A faster phaseout for the $1,400 checks in President Joe Biden's stimulus plan would exclude more than 16 million Americans from receiving one, according to a preliminary analysis from the left-leaning Institute on Taxation and Economic Policy.

The president on Wednesday approved a compromise on the direct payments that would trim the number of people eligible for the payment. The checks would phase out entirely for individuals making more than $80,000 and for married couples making over $160,000.

The income caps were previously set at $100,000 for individuals and $200,000 for couples, in the legislation that House Democrats approved on Saturday.

Biden's compromise leaves nearly 11.8 million adults ineligible for any payment at all, according to ITEP research. About 4.6 million fewer children will be in families that benefit from the new payment threshold.

This means a large number of these people will have received a stimulus check from the Trump administration, but not from Biden's, as the past income thresholds were in place in earlier pandemic aid packages.

Still, the bottom 60% of Americans by income wouldn't see any difference in the size of checks received, meaning the vast majority of people in need of financial assistance would receive a check from the federal government.

The compromise follows moderate Senate Democrats pushing the White House to keep wealthier Americans from receiving the payments. The group of moderates — nine of them in particular — led an effort in recent days to curtail direct aid provisions from reaching wealthier households.

Two Democratic aides confirmed to Insider on Wednesday that federal unemployment benefits included in the stimulus proposal remain at $400 per week through the end of August. Sen. Joe Manchin — one of the Democratic lawmakers urging a faster phaseout — said Tuesday he supported a $300 supplement that would expire earlier in the summer.

Sen. Michael Bennet of Colorado called the shift a "more appropriate way of bringing [stimulus talks] to a conclusion." Sen. Jeanne Shaheen of New Hampshire had previously suggested funding a pool of cash for broadband and healthcare providers by cutting down on stimulus-check eligibility.

Calls for fiscal support to provide aid to lower-income Americans have generated a divide in the Democratic party, breaking down between Senate and House lines.

Some progressive Democrats in the House criticized the changes to the package. The adjustment is "more of the Senate silliness" that's holding back much-needed relief, Rep. Mark Pocan of Wisconsin said Wednesday.

"People are getting big heads over the one or two people who can hold things up, and because of it they'll negotiate anything stupid just to say they negotiated," he added. "I don't know if it pays to just jockey back and forth."

The direct payments were the "easiest, simplest, most popular, populist" elements of the $1.9 trillion proposal, Rep. Pramila Jayapal of Washington said.

"If this is the only change that's one thing, if there are other changes that's going to be a different thing," Jayapal told reporters on Wednesday.

Senate Democrats are slated to debate the stimulus package on Wednesday. An amendment process will follow on Thursday. Biden has indicated he aims to approve the plan before expanded unemployment insurance lapses in mid-March.
