CNN  — 

Congress is negotiating a fresh stimulus package that would include a third round of stimulus checks, but while there’s broad agreement on the need for more direct payments, it will take weeks before any go out.

The upcoming second impeachment trial of former President Donald Trump will push back any congressional action, and lawmakers are scheduled to be on recess over President’s Day – meaning there may not be progress on a deal until later in the month.

It takes at least several days to get the first payments processed after any legislation is signed, and has taken months to deliver payments to everyone who’s eligible. Treasury is still trying to reach some people who should have gotten paid in the first round last year.

What to know about the timeline

President Joe Biden is urging lawmakers to include money for additional direct payments in a sweeping Covid relief bill. While the Senate passed a key procedural step early Friday that will allow Democrats to pass the legislation without the threat of a filibuster from Republicans – lawmakers will only now start drafting the bill text.

A final vote could possibly come in late February, after the impeachment trial is complete in the Senate. Lawmakers hope to pass the legislation by March 14.

If and when the bill passes – and if it includes new stimulus payments – it’s possible the Internal Revenue Service can start sending the money quickly to people whose bank details are on file.

When the $600 payments were approved in late December, it took the agency just two days after Trump signed the bill to start delivering the money. But new eligibility restrictions that lawmakers are considering could potentially slow down the process.

How much will the payments be?

Biden has asked Congress to send an additional $1,400 to Americans who are already getting $600 under the package approved by Congress in December, bringing the total to $2,000.

But a group of 10 Republicans, who sent their own proposal to Biden earlier this week, called for $1,000 payments. Biden has said he would like to garner bipartisan support for the bill, but made clear in a call with House Democrats Wednesday, that the top-line number is not negotiable.

Who will be eligible?

Biden proposed keeping the income thresholds the same as earlier stimulus payments – but has indicated he is open to lowering them.

House Democrats have put forward a plan that would send the full payment to individuals earning less than $75,000 a year and married couples earning less than $150,000 – like previous stimulus checks. But the payments would phase out faster than earlier rounds and completely cut off individuals earning more than $100,000 and couples earning more than $200,000.

The Republican proposal would provide the full payment to individuals earning less than $40,000 a year and couples earning less than $80,000 – and the payments would phase out faster, cutting off individuals making more than $50,000 and couples making more than $100,000.

About 29 million fewer households would receive money under the Republican plan, according to analysts at the The Penn Wharton Budget Model, who warned that the figures are preliminary since no formal legislative text is available yet.

About 95% of families would qualify under Biden’s proposal, compared to 78% under the GOP plan.

A non-binding Senate vote Thursday on an amendment to tighten stimulus check eligibility got wide support, passing 99 to 1, with only GOP Sen. Rand Paul of Kentucky voting against it. The amendment did not specify who will not be eligible for the payments outside of saying “upper income taxpayers are not eligible,” and does not mean the eligibility requirements will be changed in the final bill. But it does show bipartisan support to make a change.
