LETTER FROM THE CEO

[Photo of Robert J. Manning]

Dear Shareholders,
It has been said that change is the only constant in life. As investors have
seen, that theme is still accurate today as we recently have experienced
shifting economic cycles because of natural disasters and political instability
around the globe.

Markets worldwide have fluctuated in the past year as devastating hurricanes had
a dramatic effect on the international economy, particularly on oil prices. We
witnessed political unrest in the Middle East, highlighted by instability in
Iraq, and in Africa, the usually stable Nigeria also experienced violence. As a
result, energy prices have bounced up and down, with crude oil prices at one
point topping a record $70 per barrel.

Such cycles are not uncommon and in fact have almost become the norm in our
everyday lives. What does all of this mean to you as an investor? In times like
these, it helps to know that you're working with a seasoned investment
professional who has experience to guide you through difficult times. At MFS(R),
we believe our investment management team has the knowledge and confidence to
navigate through difficult cycles and at the same time see through adversity to
find investment opportunities for our clients and shareholders.

Our investment management process, honed over 80 years, combines a unique
concept of teamwork with our unwavering focus on the long term. We firmly
believe that the best way to realize long-term financial goals - be it a college
education, a comfortable retirement, or a secure family legacy - is to follow a
three-pronged approach that focuses on longer time horizons. Allocate holdings
across the major asset classes - including stocks, bonds, and cash. Diversify
within each class to take advantage of different market segments and investing
styles. Rebalance assets regularly to maintain a desired asset allocation. Of
course, these strategies cannot guarantee a profit or protect against a loss.
This long-term approach requires diligence and patience, two traits that in our
experience are essential to capitalizing on the many opportunities the financial
markets can offer - through both up and down economic cycles.

    Respectfully,

/s/ Robert J. Manning

(a) The average credit quality of rated securities is based upon a market
    weighted average of portfolio holdings that are rated by public rating
    agencies.
(d) Duration is a measure of how much a bond's price is likely to fluctuate with
    general changes in interest rates, e.g., if rates rise 1.00%, a bond with a
    5-year duration is likely to lose about 5.00% of its value.
(i) For purposes of this graphical presentation, the bond component includes
    both accrued interest amounts and the equivalent exposure from any
    derivative holdings, if applicable.
(m) The average maturity shown is calculated using the final stated maturity on
    the portfolio's holdings without taking into account any holdings which have
    been prerefunded to an earlier date or which have a mandatory put date prior
    to the stated maturity. The average life shown takes into account these
    earlier dates.
(r) Each security is assigned a rating from Moody's Investors Service. If not
    rated by Moody's, the rating will be that assigned by Standard & Poor's.
    Likewise, if not assigned a rating by Standard & Poor's, it will be based on
    the rating assigned by Fitch, Inc. For those portfolios that hold a security
    which is not rated by any of the three agencies, the security is considered
    Not Rated. Holdings in U.S. Treasuries and government agency mortgage-backed
    securities, if any, are included in the "AAA"-rating category. Percentages
    are based on the total market value of investments as of 5/31/06.

Percentages are based on net assets as of 5/31/06, unless otherwise noted.

The portfolio is actively managed, and current holdings may be different.

INDEX DEFINITIONS

Citigroup World Government Bond Non-Dollar Hedged Index - a market
capitalization-weighted index that tracks the currency-hedged performance of the
major government bond markets, excluding the United States. Country eligibility
is determined based upon market capitalization and investability criteria.

J.P. Morgan Emerging Markets Bond Index Global (EMBI Global) - tracks total
returns for U.S.-dollar-denominated debt instruments issued by emerging market
sovereign and quasi-sovereign entities: Brady bonds, loans, and Eurobonds.

Lehman Brothers U.S. Credit Bond Index - measures publicly issued, SEC-
registered, U.S. corporate and specified foreign debentures and secured notes
that meet specified maturity, liquidity, and quality requirements.

Lehman Brothers U.S. Government/Mortgage Bond Index - measures debt issued by
the U.S. Government as well as mortgage-backed pass-through securities of Ginnie
Mae (GNMA), Fannie Mae (FNMA), and Freddie Mac (FHLMC).

Lehman Brothers U.S. High-Yield Corporate Bond Index - measures the universe of
non-investment grade, fixed rate debt. Eurobonds, and debt issues from countries
designated as emerging markets (e.g., Argentina, Brazil, Venezuela, etc.) are
excluded.

It is not possible to invest directly in an index.

NOTES TO PERFORMANCE SUMMARY

The trust's shares may trade at a discount to net asset value. Shareholders do
not have the right to cause the trust to repurchase their shares at net asset
value. When trust shares trade at a premium, buyers pay more than the net asset
value underlying trust shares, and shares purchased at a premium would receive
less than the amount paid for them in the event of the trust's liquidation. As a
result, the total returns that are calculated based on the net asset value and
New York Stock Exchange prices can be different.

The trust's monthly distributions may include a return of capital to
shareholders. Distributions that are treated for federal income tax purposes as
a return of capital will reduce each shareholder's basis in his or her shares
and, to the extent the return of capital exceeds such basis, will be treated as
gain to the shareholder from a sale of shares. Returns of shareholder capital
have the effect of reducing the trust's assets and may increase the trust's
expense ratio.

From time to time the trust may receive proceeds from litigation settlements,
without which performance would be lower.

Shareholders will be sent notices at least annually reporting the tax status of
such distributions. The notices will indicate whether any portion of such
distributions represent a return of capital. Effective August 1, 2006, the trust
will only send monthly notices reporting the tax status of such distributions
when required by SEC rules.

KEY RISK CONSIDERATIONS

The portfolio's yield and share prices change daily based on the credit quality
of its investments and changes in interest rates. In general, the value of debt
securities will decline when interest rates rise and will increase when interest
rates fall. Debt securities with longer maturity dates will be subject to
greater price fluctuations than those with shorter maturities. Mortgage
securities are subject to prepayment risk which can offer less potential for
gains in a declining interest rate environment and greater potential for loss in
a rising interest rate environment. Derivatives involve risks different from,
and greater than, those of the underlying indicator's in whose value the
derivative is based. The value of the derivative can move in unexpected ways and
result in unanticipated losses and increased volatility if the value of the
underlying indicator(s) does not move in the direction or the extent
anticipated. Interest payments on inflation adjusted debt instruments can be
unpredictable and vary based on the level of inflation. The value of floating
rate loans depends on the credit quality and adequacy of the collateral securing
the loan. Enforcing rights against the collateral may be difficult or
insufficient if the borrower of the floating rate loan defaults. Lower quality
debt securities involve substantially greater risk of default and their value
can decline significantly over time. Foreign investments can be more volatile
than U.S. investments. Changes in currency exchange rates may affect the
portfolio's net asset value, the value of dividends and interest earned and
gains and losses realized on the sale of securities. Investing in emerging
markets can involve risks in addition to those generally associated with
investing in more developed foreign markets. When you sell your shares, they may
be worth more or less than the amount you paid for them. Please see the
prospectus for further information regarding these and other risk
considerations.

These risks may increase share price volatility.

In accordance with Section 23(c) of the Investment Company Act of 1940, the
trust hereby gives notice that it may from time to time repurchase shares of the
trust in the open market at the option of the Board of Trustees and on such
terms as the Trustees shall determine.

DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN

The trust offers a Dividend Reinvestment and Cash Purchase Plan that allows you
to reinvest either all of the distributions paid by the trust or only the
long-term capital gains. Purchases are made at the market price unless that
price exceeds the net asset value (the shares are trading at a premium). If the
shares are trading at a premium, purchases will be made at a discounted price of
either the net asset value or 95% of the market price, whichever is greater.
Twice each year you can also buy shares. Investments may be made in any amount
over $100 in January and July on the 15th of the month or shortly thereafter.

If your shares are in the name of a brokerage firm, bank, or other nominee, you
can ask the firm or nominee to participate in the plan on your behalf. If the
nominee does not offer the plan, you may wish to request that your shares be
re-registered in your own name so that you can participate.

There is no service charge to reinvest distributions, nor are there brokerage
charges for shares issued directly by the trust. However, when shares are bought
on the New York Stock Exchange or otherwise on the open market, each participant
pays a pro rata share of the commissions. The automatic reinvestment of
distributions does not relieve you of any income tax that may be payable (or
required to be withheld) on the distributions.

To enroll in or withdraw from the plan, or if you have any questions, call
1-800-637-2304 any business day from 8 a.m. to 8 p.m. Eastern time. Please have
available the name of the trust and your account and Social Security numbers.
For certain types of registrations, such as corporate accounts, instructions
must be submitted in writing. Please call for additional details. When you
withdraw from the plan, you can receive the value of the reinvested shares in
one of two ways: a check for the value of the full and fractional shares, or a
certificate for the full shares and a check for the fractional shares.

NOTES TO FINANCIAL STATEMENTS (unaudited)

(1) BUSINESS AND ORGANIZATION

MFS Charter Income Trust (the trust) is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended, as
a closed-end management investment company.

(2) SIGNIFICANT ACCOUNTING POLICIES

GENERAL - The preparation of financial statements in conformity with U.S.
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. The trust
can invest in foreign securities, including securities of emerging market
issuers. Investments in foreign securities are vulnerable to the effects of
changes in the relative values of the local currency and the U.S. dollar and to
the effects of changes in each country's legal, political, and economic
environment. The markets of emerging markets countries are generally more
volatile than the markets of developed countries with more mature economies. All
of the risks of investing in foreign securities previously described are
heightened when investing in emerging markets countries.

INVESTMENT VALUATIONS - Debt instruments (other than short-term instruments),
including restricted debt instruments, are generally valued at an evaluated or
composite bid as reported by an independent pricing service. Values of debt
instruments obtained from pricing services can utilize both dealer-supplied
valuations and electronic data processing techniques, which take into account
factors such as institutional-size trading in similar groups of securities,
yield, quality, coupon rate, maturity, type of issue, trading characteristics
and other market data. Equity securities, including restricted equity
securities, are generally valued at the last sale or official closing price as
reported by an independent pricing service on the market or exchange on which
they are primarily traded. For securities for which there were no sales reported
that day, equity securities are generally valued at the last quoted daily bid
quotation as reported by an independent pricing service on the market or
exchange on which they are primarily traded. Short-term instruments with a
maturity at issuance of 397 days or less are generally valued at amortized cost,
which approximates market value. Futures contracts are generally valued at last
posted settlement price as reported by an independent pricing service on the
market on which they are primarily traded. Futures contracts for which there
were no trades that day for a particular position are generally valued at the
closing bid quotation as reported by an independent pricing service on the
market on which they are primarily traded. Forward foreign currency contracts
are generally valued at the mean of bid and asked prices for the time period
interpolated from rates reported by an independent pricing service for proximate
time periods. Swaps are generally valued at a broker-dealer bid quotation.
Securities and other assets generally valued on the basis of information from an
independent pricing service may also be valued at a broker-dealer bid quotation.
The values of foreign securities and other assets and liabilities expressed in
foreign currencies are converted to U.S. dollars using the mean of bid and asked
prices for rates reported by an independent pricing service. The Board of
Trustees has delegated primary responsibility for determining or causing to be
determined the value of the trust's investments (including any fair valuation)
to the adviser pursuant to valuation policies and procedures approved by the
Board. If the adviser determines that reliable market quotations are not readily
available, investments are valued at fair value as determined in good faith by
the adviser in accordance with such procedures under the oversight of the Board
of Trustees. Under the trust's valuation policies and procedures, market
quotations are not considered to be readily available for many types of debt
instruments. These investments are generally valued at fair value based on
information from independent pricing services. The adviser may rely on
independent pricing services or other information (such as the correlation with
price movements of similar securities in the same or other markets; the type,
cost and investment characteristics of the security; the business and financial
condition of the issuer; and trading and other market data) to assist in
determining whether to fair value and at what value to fair value an investment.
The value of an investment for purposes of calculating the trust's net asset
value can differ depending on the source and method used to determine value.
When fair valuation is used, the value of investments used to determine the
trust's net asset value may differ from quoted or published prices for the same
investments.

REPURCHASE AGREEMENTS - The trust may enter into repurchase agreements with
institutions that the trust's investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The trust requires
that the securities collateral in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the trust to obtain those securities
in the event of a default under the repurchase agreement. The trust monitors, on
a daily basis, the value of the collateral to ensure that its value, including
accrued interest, is greater than amounts owed to the trust under each such
repurchase agreement. The trust, along with other affiliated entities of
Massachusetts Financial Services Company (MFS), may utilize a joint trading
account for the purpose of entering into one or more repurchase agreements.

INFLATION-ADJUSTED DEBT SECURITIES - The trust invests in inflation-adjusted
debt securities issued by the U.S. Treasury. The trust may also invest in
inflation-adjusted debt securities issued by U.S. Government agencies and
instrumentalities other than the U.S. Treasury and by other entities such as
U.S. and foreign corporations and foreign governments. The principal value of
these debt securities is adjusted by references to changes in the Consumer Price
Index or another general price or wage index. These debt securities typically
pay a fixed rate of interest, but this fixed rate is applied to the
inflation-adjusted principal amount. The principal paid at maturity of the debt
security is typically equal to the inflation-adjusted principal amount, or the
security's original par value, whichever is greater. Other types of
inflation-adjusted securities may use other methods to adjust for other measures
of inflation.

FOREIGN CURRENCY TRANSLATION - Purchases and sales of foreign investments,
income, and expenses are converted into U.S. dollars based upon currency
exchange rates prevailing on the respective dates of such transactions. Gains
and losses attributable to foreign currency exchange rates on sales of
securities are recorded for financial statement purposes as net realized gains
and losses on investments. Gains and losses attributable to foreign exchange
rate movements on income and expenses are recorded for financial statement
purposes as foreign currency transaction gains and losses. That portion of both
realized and unrealized gains and losses on investments that results from
fluctuations in foreign currency exchange rates is not separately disclosed.

DERIVATIVE RISK - The trust may invest in derivatives for hedging or non-
hedging purposes. While hedging can reduce or eliminate losses, it can also
reduce or eliminate gains. When the trust uses derivatives as an investment to
gain market exposure, or for hedging purposes, gains and losses from derivative
instruments may be substantially greater than the derivative's original cost.
Derivative instruments include forward foreign currency exchange contracts, swap
agreements, and futures contracts.

FUTURES CONTRACTS - The trust may enter into futures contracts for the delayed
delivery of securities or currency, or contracts based on financial indices at a
fixed price on a future date. In entering such contracts, the trust is required
to deposit with the broker either in cash or securities an amount equal to a
certain percentage of the contract amount. Subsequent payments are made or
received by the trust each day, depending on the daily fluctuations in the value
of the contract, and are recorded for financial statement purposes as unrealized
gains or losses by the trust. Upon entering into such contracts, the trust bears
the risk of interest or exchange rates or securities prices moving unexpectedly,
in which case, the trust may not achieve the anticipated benefits of the futures
contracts and may realize a loss.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS - The trust may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of the contract. The trust may enter into forward foreign currency exchange
contracts for hedging purposes as well as for non-hedging purposes. For hedging
purposes, the trust may enter into contracts to deliver or receive foreign
currency it will receive from or require for its normal investment activities.
The trust may also use contracts in a manner intended to protect foreign
currency denominated securities from declines in value due to unfavorable
exchange rate movements. For non-hedging purposes, the trust may enter into
contracts with the intent of changing the relative exposure of the trust's
portfolio of securities to different currencies to take advantage of anticipated
changes. The forward foreign currency exchange contracts are adjusted by the
daily exchange rate of the underlying currency and any gains or losses are
recorded as unrealized until the contract settlement date. On contract
settlement date, the gains or losses are recorded as realized gains or losses on
foreign currency transactions.

SWAP AGREEMENTS - The trust may enter into swap agreements. A swap is an
exchange of cash payments between the trust and another party. Net cash payments
are exchanged at specified intervals and are recorded as a realized gain or loss
in the Statement of Operations. The value of the swap is adjusted daily and the
change in value is recorded as unrealized appreciation or depreciation in the
Statement of Operations. Risks may arise upon entering into these agreements
from the potential inability of counterparties to meet the terms of their
contract and from unanticipated changes in the value of the financial index on
which the swap agreement is based.

CREDIT DEFAULT SWAPS - The trust may enter into credit default swaps to limit or
to reduce risk exposure of the trust to credit events such as bankruptcy,
failure to pay, or a restructuring of corporate and sovereign issuers. The trust
may also use credit default swaps to create direct or synthetic short or long
exposure to domestic or foreign corporate debt securities or certain sovereign
debt securities to which the trust is not otherwise exposed. In a credit default
swap, one party makes a stream of payments to another party in exchange for the
right to receive a specified return in the event of a default by a third party,
such as a corporate issuer or foreign issuer on its obligation.

SECURITY LOANS - State Street Bank and Trust Company ("State Street"), as
lending agent, may loan the securities of the trust to certain qualified
institutions (the "Borrowers") approved by the trust. The loans are
collateralized at all times by cash and/or U.S. Treasury securities in an amount
at least equal to the market value of the securities loaned. State Street
provides the trust with indemnification against Borrower default. The trust
bears the risk of loss with respect to the investment of cash collateral. On
loans collateralized by cash, the cash collateral is invested in a money market
fund or short-term securities. A portion of the income generated upon investment
of the collateral is remitted to the Borrowers, and the remainder is allocated
between the trust and the lending agent. On loans collateralized by U.S.
Treasury securities, a fee is received from the Borrower, and is allocated
between the trust and the lending agent. Income from securities lending is
included in interest income on the Statement of Operations. The dividend and
interest income earned on the securities loaned is accounted for in the same
manner as other dividend and interest income. At May 31, 2006, there were no
securities on loan.

INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded on the
trade date. Interest income is recorded on the accrual basis. All premium and
discount is amortized or accreted for financial statement purposes in accordance
with U.S. generally accepted accounting principles. All discount is accreted for
tax reporting purposes as required by federal income tax regulations. Dividends
received in cash are recorded on the ex-dividend date. Certain dividends from
foreign securities will be recorded when the trust is informed of the dividend
if such information is obtained subsequent to the ex- dividend date. Dividend
and interest payments received in additional securities are recorded on the
ex-dividend or ex-interest date in an amount equal to the value of the security
on such date. The trust may receive proceeds from litigation settlements
involving its portfolio holdings. Any proceeds received are reflected in
realized gain/loss in the Statement of Operations, or in unrealized gain/loss if
the security is still held by the trust.

FEES PAID INDIRECTLY - The trust's custody fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by the
trust. This amount, for the six months ended May 31, 2006, is shown as a
reduction of total expenses on the Statement of Operations.

TAX MATTERS AND DISTRIBUTIONS - The trust intends to continue to qualify as a
regulated investment company, as defined under Subchapter M of the Internal
Revenue Code, and to distribute all of its taxable income, including realized
capital gains. Accordingly, no provision for federal income tax is required in
the financial statements. Foreign taxes, if any, have been accrued by the trust
in the accompanying financial statements.

Distributions to shareholders are recorded on the ex-dividend date. Income and
capital gain distributions are determined in accordance with income tax
regulations, which may differ from generally accepted accounting principles.
Certain capital accounts in the financial statements are periodically adjusted
for permanent differences in order to reflect their tax character. These
adjustments have no impact on net assets or net asset value per share. Temporary
differences which arise from recognizing certain items of income, expense, gain
or loss in different periods for financial statement and tax purposes will
reverse at some time in the future. Distributions in excess of net investment
income or net realized gains are temporary overdistributions for financial
statement purposes resulting from differences in the recognition or
classification of income or distributions for financial statement and tax
purposes.

Book/tax differences primarily relate to amortization and accretion of debt
securities, defaulted bonds, wash sale loss deferrals, straddle loss deferrals,
foreign currency transactions, and derivative transactions.

The tax character of distributions made during the current period will be
determined at fiscal year end.

The tax character of distributions declared to shareholders is as follows:

                                    NOVEMBER 30, 2005   NOVEMBER 30, 2004
    Ordinary income (including any
    short-term capital gains)             $29,042,810         $31,836,028

The federal tax cost and the tax basis components of distributable earnings were
as follows:

          AS OF MAY 31, 2006
          Cost of investments                          $541,116,892

          Capital loss carryforwards                    (45,279,622)
          Other temporary differences                    (1,990,248)
          Net unrealized appreciation (depreciation)    (13,923,198)

The aggregate cost above includes prior fiscal year end tax adjustments.

As of May 31, 2006, the trust had available capital loss carryforwards to offset
future realized gains. Such losses expire as follows:

              November 30, 2009                        $(21,374,410)

(3) TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISER - The trust has an investment advisory agreement with MFS to
provide overall investment advisory and administrative services, and general
office facilities.

The management fee is computed daily and paid monthly at an annual rate of 0.32%
of the trust's average daily net assets and 4.57% of gross investment income.
The management fee, from net assets and gross investment income, incurred for
the six months ended May 31, 2006 was equivalent to an annual effective rate of
0.59% of the trust's average daily net assets.

TRANSFER AGENT - The trust pays a portion of transfer agent and dividend-
disbursing costs to MFS Service Center, Inc. (MFSC), a wholly-owned subsidiary
of MFS. MFSC receives a fee from the trust, for its services as registrar and
dividend-disbursing agent. The agreement provides that the trust will pay MFSC
an account maintenance fee of no more than $9.00 and a dividend services fee of
$0.75 per reinvestment. For the six months ended May 31, 2006, these fees
amounted to $37,200. MFSC also receives payment from the trust for out-of-pocket
expenses paid by MFSC on behalf of the trust. For the six months ended May 31,
2006, these costs amounted to $11,868.

ADMINISTRATOR - MFS provides certain financial, legal, shareholder
communications, compliance, and other administrative services to certain funds
for which MFS acts as investment adviser. Under an administrative services
agreement, the funds may partially reimburse MFS the costs incurred to provide
these services, subject to review and approval by the Board of Trustees. Each
fund is charged a fixed amount plus a fee based on calendar year average net
assets. From July 1, 2005 through March 31, 2006, the trust's annual fixed
amount was $10,000. Effective April 1, 2006, the trust's annual fixed amount is
$17,500.

The administrative services fee incurred for the six months ended May 31, 2006
was equivalent to an annual effective rate of 0.0145% of the trust's average
daily net assets.

TRUSTEES' AND OFFICERS' COMPENSATION - The trust pays compensation to
Independent Trustees in the form of a retainer, attendance fees, and additional
compensation to Board and Committee chairpersons. The trust does not pay
compensation directly to Trustees or to officers of the trust who are also
officers of the investment adviser, all of whom receive remuneration for their
services to the trust from MFS. Certain officers and Trustees of the trust are
officers or directors of MFS and MFSC. The trust has an unfunded, defined
benefit plan for certain retired Independent Trustees which resulted in a
pension expense of $2,496. The trust also has an unfunded retirement benefit
deferral plan for certain Independent Trustees which resulted in an expense of
$1,017. Both amounts are included in Independent trustees' compensation for the
six months ended May 31, 2006. The deferred liability for retirement benefits
payable to certain Trustees under both plans amounted to $155,871 at May 31,
2006, and is included in payable for independent trustees' compensation.

DEFERRED TRUSTEE COMPENSATION - Under a Deferred Compensation Plan (the Plan)
Independent Trustees previously were allowed to elect to defer receipt of all or
a portion of their annual compensation. Trustees are no longer allowed to defer
compensation under the Plan. Amounts previously deferred are treated as though
equivalent dollar amounts had been invested in shares of the trust or other MFS
funds selected by the Trustee. Deferred amounts represent an unsecured
obligation of the trust until distributed in accordance with the Plan. Included
in other assets and payable for independent trustees' compensation is $12,717 of
Deferred Trustees' Compensation.

OTHER - This trust and certain other MFS funds (the funds) have entered into a
services agreement (the Agreement) which provides for payment of fees by the
funds to Tarantino LLC in return for the provision of services of an Independent
Chief Compliance Officer (ICCO) for the funds. The ICCO is an officer of the
funds and the sole member of Tarantino LLC. The funds can terminate the
Agreement with Tarantino LLC at any time under the terms of the Agreement. For
the six months ended May 31, 2006, the fee paid to Tarantino LLC was $2,195. MFS
has agreed to reimburse the trust for a portion of the payments made by the
funds to Tarantino LLC in the amount of $1,842, which is shown as a reduction of
total expenses in the Statement of Operations. Additionally, MFS has agreed to
bear all expenses associated with office space, other administrative support,
and supplies provided to the ICCO.

(6) LINE OF CREDIT

The trust and other affiliated funds participate in a $1 billion unsecured
committed line of credit provided by a syndication of banks under a credit
agreement. In addition, the trust and other affiliated funds have established
uncommitted borrowing arrangements with certain banks. Borrowings may be made
for temporary financing needs. Interest is charged to each fund, based on its
borrowings, at a rate equal to the Federal Reserve funds rate plus 0.35%. In
addition, a commitment fee, based on the average daily, unused portion of the
committed line of credit, is allocated among the participating funds at the end
of each calendar quarter. The commitment fee allocated to the trust for the six
months ended May 31, 2006 was $2,681 and is included in miscellaneous expense on
the Statement of Operations. The trust had no significant borrowings during the
six months ended May 31, 2006.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Trustees and Shareholders of the MFS Charter Income Trust:

We have reviewed the accompanying statement of assets and liabilities of the MFS
Charter Income Trust (the Trust), including the portfolio of investments, as of
May 31, 2006, and the related statements of operations, changes in net assets,
and financial highlights for the six-month period ended May 31, 2006. These
interim financial statements are the responsibility of the Trust's management.

We conducted our review in accordance with the standards of the Public
Accounting Oversight Board (United States). A review of interim financial
information consists principally of applying analytical procedures and making
inquiries of persons responsible for financial and accounting matters. It is
substantially less in scope than an audit conducted in accordance with the
standards of the Public Company Accounting Oversight Board (United States), the
objective of which is the expression of an opinion regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to the accompanying interim financial statements for them to be in
conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the statement of changes in
net assets for the year ended November 30, 2005, and financial highlights for
each of the five years in the period ended November 30, 2005, and in our report
dated January 10, 2006, we expressed an unqualified opinion on such statement of
changes in net assets and financial highlights.

Note: The Board of Trustees approves procedures to repurchase Fund shares
annually. The notification to shareholders of the program is included in the

10b-18 of the Securities Exchange Act of 1934 and limit the aggregate number of
Fund shares that may be repurchased in each annual period (March 1 through the
following February 28) to 10% of the Registrant's outstanding shares as of the
first day of the plan year (March 1). The aggregate number of Fund shares
available for repurchase for the March 1, 2006 plan year are 5,600,554.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

There were no material changes to the procedures by which shareholders may send
recommendations to the Board for nominees to the Registrant's Board since the
Registrant last provided disclosure as to such procedures in response to the
requirements of Item 7(d)(2)(ii)(G) of Schedule 14A or this Item.

ITEM 11. CONTROLS AND PROCEDURES.

(a) Based upon their evaluation of the effectiveness of the registrant's
    disclosure controls and procedures (as defined in Rule 30a-3(c) under the
    Investment Company Act of 1940 (the "Act")) as conducted within 90 days of
    the filing date of this Form N-CSR, the registrant's principal financial
    officer and principal executive officer have concluded that those
    disclosure controls and procedures provide reasonable assurance that the
    material information required to be disclosed by the registrant on this
    report is recorded, processed, summarized and reported within the time
    periods specified in the Securities and Exchange Commission's rules and
    forms.

(b) There were no changes in the registrant's internal controls over financial
    reporting (as defined in Rule 30a-3(d) under the Act) that occurred during
    the second fiscal quarter of the period covered by the report that have
    materially affected, or are reasonably likely to materially affect, the
    registrant's internal control over financial reporting.

(a) File the exhibits listed below as part of this Form. Letter or number the
    exhibits in the sequence indicated.

    (1) Any code of ethics, or amendment thereto, that is the subject of the
        disclosure required by Item 2, to the extent that the registrant
        intends to satisfy the Item 2 requirements through filing of an
        exhibit.

    (2) A separate certification for each principal executive officer and
        principal financial officer of the registrant as required by Rule 30a-2
        under the Act (17 CFR 270.30a-2): Attached hereto.

(b) If the report is filed under Section 13(a) or 15(d) of the Exchange Act,
    provide the certifications required by Rule 30a-2(b) under the Act (17 CFR
    270.30a-2(b)), Rule 13a-14(b) or Rule 15d-14(b) under the Exchange Act (17
    CFR 240.13a-14(b) or 240.15d-14(b)) and Section 1350 of Chapter 63 of Title
    18 of the United States Code (18 U.S.C. 1350) as an exhibit. A
    certification furnished pursuant to this paragraph will not be deemed
    "filed" for the purposes of Section 18 of the Exchange Act (15 U.S.C. 78r),
    or otherwise subject to the liability of that section. Such certification
    will not be deemed to be incorporated by reference into any filing under
    the Securities Act of 1933 or the Exchange Act, except to the extent that
    the registrant specifically incorporates it by reference: Attached hereto.
