The American Rescue Plan will now head to the House for final approval, which could happen as soon as Tuesday. Once Congress approves the emergency aid bill, President Biden needs to sign the legislation to release the money; he’s widely expected to do so before Sunday, when two key jobless aid programs are set to expire.

The IRS and Treasury Department would then distribute the cash payments through direct deposit, mailed checks and prepaid debit cards.

The federal government took about two weeks to start distributing the first round of $1,200 payments in April, and about one week to send the second round of checks, worth $600, in January. White House press secretary Jen Psaki said Monday that Biden expects a “large number” of Americans to receive checks by the end of March.

Here’s the line items on the $2 Trillion dollar stimulus deal

The cash payments included in the nearly $2 trillion stimulus bill are the largest yet, with individuals earning $75,000 or less eligible to receive the fully promised $1,400. Couples earning $150,000 or less will receive a check worth $2,800. Households will receive an additional $1,400 for each dependent child claimed on their most-recent tax filings.

As with previous rounds, Americans who earn more than the threshold line will still receive a partial check. But the money will phase out faster than previous rounds, cutting off payments for roughly 16 million Americans who qualified for previous relief payments, according to a preliminary analysis published by the left-leaning Institute on Taxation and Economic Policy.

Individuals making $80,000 a year or more and couples making $160,000 a year, or higher, no longer qualify for the checks. That means individuals earning between $80,000 and $100,000, and couples earning between $160,000 and $200,000, are newly excluded from a partial check under the legislation.

The American Rescue Plan also extends unemployment benefits at $300 a week through August, expands the child tax credit to offer parents up to $3,600 per child, includes $350 billion in funding for state and local governments and allocates billions of dollars for vaccine distribution.
