The IRS will use your Form SSA-1099 to access your information and send your Economic Impact Payment (EIP). Your payment will be delivered the same way as your Social Security Disability Insurance (SSDI) benefits.
If you have qualifying children under age 17, you must use the Non-Filers: Enter Payment Info tool before Wednesday, April 22 at noon Eastern time to claim the additional $500 payment per child.
If you never received the additional $500 per qualifying child, SS, SSI, RR, and VA can use the Non-Filers: Enter Payment Info tool to update your information 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.
