The IRS will be processing payments until the end of 2020. Eligible persons who don’t receive their payment prior to December 31, 2020 will have the opportunity to claim their stimulus payment when they file their 2020 tax return in 2021.
Those who receive a smaller stimulus payment than expected should be able to claim the additional amount they qualify to receive when they file their 2020 tax return. Be sure to keep your confirmation letter for the EIP—it should arrive within a few weeks after you receive your payment.
Those who used the Non-Filers tool by the deadline to provide information about any qualifying children, but did not get the additional $500 payment together with their initial EIP, will be paid in early August.
If you receive government benefits, aren’t required to file a tax return, and never received the additional $500 per qualifying child, use the Non-Filers: Enter Payment Info tool to update your information. SS, SSI, RR, and VA recipients must act before Wednesday, September 30 to receive their additional payment in October.
It is unclear whether SSDI recipients could qualify for this window to update their information, but it doesn’t hurt to try—at the end of the day, you should receive your additional $500 when you receive your refund in 2021 if you don’t get it sooner.
