The third stimulus check went to most SSDI recipients automatically via direct deposit in March 2021

The third Economic Impact Payment (the third stimulus check) was distributed by the IRS starting March 17, 2021. If you received SSDI or SSI benefits and had your payment set up for direct deposit, the IRS used that same bank account to send your stimulus money. You did not have to do anything—the payment arrived on the schedule the IRS published based on your Social Security number.

This was different from the first two stimulus checks, which had more complicated routing for people on Social Security. By the third round, the IRS and Social Security Administration had refined the process so that direct deposit information already on file with Social Security transferred automatically to the IRS payment system.

The third stimulus check amount was $1,400 per person for most adults, plus $1,400 for each dependent child under 17. If you were claimed as a dependent on someone else's tax return, you did not receive a separate payment. The payment was not taxable income and did not affect your SSDI benefits or Medicare coverage.

Key Takeaways

  • The IRS sent the third stimulus payment to the same bank account where your SSDI direct deposit was set up, with no action required from you.
  • Payments began arriving March 17, 2021, and the timing depended on your Social Security number, not your process date.
  • The $1,400 payment did not count as income for SSDI purposes and did not reduce your monthly benefit amount.
  • If your direct deposit information was outdated or missing, the IRS mailed a paper check instead, which could take several weeks longer to arrive.

Why direct deposit was used for SSDI recipients

The IRS chose to route stimulus payments through existing direct deposit accounts because it was the fastest and most reliable method. Social Security maintains direct deposit information for nearly all SSDI beneficiaries—most people set this up when they first started receiving benefits. The IRS had a data-sharing agreement with the Social Security Administration that allowed them to access this banking information for the stimulus payment.

This approach avoided the delays that came with mailing paper checks. A mailed check could take two to three weeks to arrive, and if it was lost or stolen, replacement could take another month. Direct deposit meant the money was in your account within one or two business days of the IRS processing your payment.

For people who did not have direct deposit set up, the IRS mailed a paper check to the address on file with Social Security. If that address was wrong, the check could be returned to the IRS, and you would have had to contact them to update your information and request a reissue.

The payment schedule based on Social Security number

The IRS staggered the third stimulus payments over several weeks to avoid overwhelming the banking system. The schedule was based on your Social Security number, not when you filed taxes or when you applied for anything. The IRS published a calendar showing which Social Security number ranges would receive payments on which dates.

Most SSDI recipients saw their payment between March 17 and April 7, 2021. If your Social Security number ended in 00–09, your payment typically arrived by March 24. If it ended in 70–99, it arrived closer to April 7. This was the IRS's standard method for distributing large payments to millions of people at once.

The payment appeared in your bank account as a deposit from "IRS TREAS 310." You could track the exact date using the IRS's "Get My Payment" tool on the IRS website, which was updated daily as payments were processed.

What happened if your direct deposit information was incorrect or missing

If your bank account information on file with Social Security was closed, outdated, or belonged to a joint account that had been frozen, the IRS's initial deposit could fail. When this happened, the IRS did not when ready try a second time. Instead, they flagged your case and mailed a paper check to your address on file.

A paper check took significantly longer—often four to six weeks from the time the IRS mailed it. If you moved and did not update your address with Social Security, the check went to your old address and could be returned as undeliverable. If that happened, you had to contact the IRS directly to claim the payment.

Some people discovered their direct deposit had failed only when they did not see the payment arrive on the expected date. The IRS did not send a notice in advance; you had to check your bank account or use the Get My Payment tool to see the status.

How the third stimulus affected your SSDI and Medicare

The third stimulus payment did not count as income for SSDI purposes. Social Security did not reduce your monthly benefit because you received the check. This was true even though stimulus payments in prior years had sometimes created confusion about whether they were "income" under Social Security rules.

Congress explicitly excluded stimulus payments from the definition of income for both SSDI and SSI. This meant the payment did not affect your work incentives, your Medicare coverage, or your Medicaid coverage (if you were also on Medicaid). You could keep the full $1,400 without any reduction to your benefits.

The payment also did not affect your taxes. You did not have to report it as income on your federal tax return, and it did not change your tax filing status or your may be able to access for tax credits in 2021.

If you did not receive the third stimulus payment

Some SSDI recipients did not receive the third stimulus payment, usually because of one of these reasons: their direct deposit failed and the paper check was lost or went to an old address; they were claimed as a dependent on someone else's tax return; or their Social Security number was flagged in the IRS system for a reason unrelated to the stimulus (such as an identity theft report or a prior tax issue).

If you did not receive your payment by mid-April 2021, you could file a 2021 tax return claiming the payment as a "Recovery Rebate Credit." This was a tax credit that you could claim even if you did not normally file taxes. The credit was worth $1,400 per person, plus $1,400 per dependent, and you could claim it retroactively on your 2021 return.

To claim the credit, you needed to file Form 1040 or 1040-SR with Schedule 3 (Form 1040), which is where you report the Recovery Rebate Credit. If you needed help filing, you could contact a local tax preparation service or the IRS's Volunteer Income Tax information (VITA) program, which offers free tax help to people with low income.

Frequently Asked Questions

Did the third stimulus check reduce my SSDI monthly payment?

No. Congress excluded stimulus payments from the definition of income for SSDI and SSI. Your monthly benefit amount did not change because you received the $1,400 payment. The money was yours to keep in full.

Why did my stimulus payment go to a closed bank account?

The IRS used the direct deposit information on file with Social Security, which may not have been updated if you closed that account after you set up direct deposit. If the deposit failed, the IRS mailed a paper check instead. You can update your direct deposit information with Social Security at any time by visiting ssa.gov or calling 1-800-772-1213.

Can I still claim the third stimulus if I never received it?

Yes. You can claim the $1,400 as a Recovery Rebate Credit on your 2021 tax return (or an amended return if you already filed). File Form 1040 with Schedule 3 and report the credit. If you need help, VITA programs offer free tax preparation.

Did the stimulus payment count as income for Medicare or Medicaid?

No. The stimulus payment did not count as income for either program. Your Medicare premiums and Medicaid coverage were not affected by receiving the $1,400 payment.

What if I was claimed as a dependent—could I get a stimulus payment?

No. If you were claimed as a dependent on someone else's tax return, you did not receive a separate stimulus payment. Only the person who claimed you could receive $1,400 for you as part of their payment. This applied even if you were an adult receiving SSDI.
