IRS is sending more 'plus-up' stimulus payments to taxpayers who already filed their 2020 tax returns. More than 700,000 Americans will receive a supplemental stimulus payment this week as the IRS continues to process 2020 tax returns, the agency said Wednesday.

Will stimulus checks come in multiple payments?

"In most cases, the second payment will be delivered as directed by the tax return. In a few instances, one payment may come as a direct deposit and the other mailed. The second payment may come the same week or within weeks of the first payment."

Are the second set of stimulus checks being sent out?

The Internal Revenue Service announced Monday that it will begin sending out the second batch of $1,400 stimulus payments this week, this time via paper checks and prepaid debit cards sent through the mail as well as by direct deposit.
