The third stimulus check arrived on SSDI accounts in waves between March and May 2021

The third Economic Impact Payment (the $1,400 check authorized under the American Rescue Plan Act in March 2021) was deposited to SSDI recipients' bank accounts starting March 17, 2021. The IRS and Treasury Department prioritized direct deposit over paper checks, so if you received SSDI benefits via direct deposit, your payment arrived first. Paper checks began mailing in late March and continued through May 2021, with delivery times depending on postal service speed in your area.

Unlike the first two stimulus rounds, the third payment did not require SSDI recipients to file a tax return or take any action to receive it. The IRS matched its records against Social Security Administration data to identify who was may have access to to the payment. If you were receiving SSDI on the payment date (March 11, 2021), you were included automatically.

The timing of your deposit depended on three factors: whether you used direct deposit, the bank's processing speed, and whether the IRS had your correct account information on file. Direct deposit recipients typically saw funds within one to three business days of the IRS release date. Those who received paper checks waited anywhere from two to four weeks after mailing, depending on mail volume and distance.

Key Takeaways

  • SSDI recipients who used direct deposit received the third stimulus check between March 17 and late March 2021; paper check recipients received theirs between late March and May 2021.
  • No action was required from SSDI beneficiaries—the IRS automatically identified may be able to access recipients using Social Security Administration records.
  • The payment amount was $1,400 per person, with no reduction based on SSDI income or benefit amount.
  • If you did not receive your third stimulus check by June 2021, you could claim it on your 2021 tax return using the Recovery Rebate Credit.

Why SSDI recipients did not have to explore

The IRS had already established a data-sharing agreement with the Social Security Administration for the first two stimulus payments in 2020. For the third payment, the IRS used the same process: it pulled a list of all people receiving SSDI as of March 11, 2021, and cross-referenced that list against its own records to confirm identity and address. This meant SSDI recipients were treated as a group that had already proven their identity to a federal agency, eliminating the need for a separate process.

This automatic process was faster and more reliable than asking millions of people to file forms. However, it also meant that if your address or bank account information was outdated in either the IRS or Social Security's records, your check could be mailed to an old address or deposited to a closed account. The IRS later issued a tool called "Get My Payment" that let people check the status of their third stimulus check and update their information if needed.

What happened if your check did not arrive on time

Some SSDI recipients experienced delays or never received their third stimulus check. Common reasons included a bank account closure between when the IRS processed the payment and when it was deposited, an address change that was not updated in IRS records, or a mismatch between the name on file and the name on the bank account.

If your check did not arrive by mid-June 2021, the IRS recommended checking the "Get My Payment" tool on IRS.gov to see whether the payment had been issued and where it was sent. If the tool showed the payment was deposited to a bank account you no longer had access to, you could contact that bank to ask whether the funds were returned to the IRS. If the tool showed the check was mailed but never arrived, you could request a replacement check through the IRS website.

For anyone who did not receive the payment by the end of 2021, the option to claim it shifted to the tax return. On the 2021 Form 1040, SSDI recipients could claim the third stimulus payment as a Recovery Rebate Credit if they had not received it. This required filing a tax return even if they normally did not file one, but the credit was refundable—meaning they could receive the full $1,400 even if they owed no tax.

How the third stimulus differed from the first two

The first stimulus payment ($1,200 per person, April 2020) and the second ($600 per person, January 2021) both required SSDI recipients to either file a tax return or submit information through a non-filer tool if they did not normally file. Many SSDI recipients missed these important date or did not know they had to take action, which delayed or prevented their payments.

The third stimulus payment eliminated this barrier. The IRS and Social Security Administration learned from the earlier rounds and built the automatic process to reach more people faster. SSDI recipients did not have to file anything, call anyone, or prove they were still alive and receiving benefits. The payment was treated as an entitlement based on benefit status as of a specific date.

This change meant that SSDI recipients who had missed the first two stimulus payments because they did not file taxes were not left behind a third time. However, it also meant that anyone who had moved, changed banks, or updated their name since their last Social Security contact might not have received the payment without taking additional steps.

SSDI and stimulus payments: tax treatment

The third stimulus payment was not counted as income for SSDI purposes. Social Security does not tax stimulus payments, and they do not reduce your monthly SSDI benefit amount. This was true for all three stimulus rounds. The payments were treated as one-time federal relief, not as earnings or unearned income that would trigger a benefit reduction.

However, stimulus payments could affect other means-tested programs. If you received Supplemental Security Income (SSI)—a different program from SSDI—the stimulus payment counted as income in the month it was received and could have reduced your SSI benefit for that month. SSDI and SSI are separate programs with different rules, so the tax treatment differed. SSDI recipients did not face this issue.

Frequently Asked Questions

Can I still claim the third stimulus check on my taxes if I never received it?

Yes, but only if you did not receive it by the end of 2021. You can claim the Recovery Rebate Credit on your 2021 tax return for the full $1,400 (or $2,800 if you were married filing jointly and your spouse also did not receive it). You must file a return to claim it, even if you normally do not file. After 2021, the important date to claim it as a credit has passed, but you may still have other options depending on your situation.

What if I received the third stimulus check but I was not supposed to?

The IRS did not ask for the third stimulus payment to be returned in most cases. If you received it by mistake—for example, if you were deceased or no longer may be able to access—the IRS may eventually contact you, but this was rare. If you received a notice from the IRS about the payment, follow the instructions in that notice. Do not assume you need to return it without official guidance.

Did the third stimulus check reduce my SSDI benefits?

No. SSDI benefits are not reduced based on stimulus payments. The payment did not count as income for Social Security purposes and did not affect your monthly benefit amount. If you received SSI instead of SSDI, the rules were different and the payment could have temporarily reduced your SSI benefit.

Why did some SSDI recipients get their check later than others?

Direct deposit recipients received payments first, usually within one to three business days of March 17, 2021. Paper check recipients waited longer because checks had to be printed and mailed. Additionally, if your bank account information was outdated or your address had changed, processing took longer or the payment was sent to an old address, causing further delays.

Is there a fourth stimulus check for SSDI recipients?

No fourth stimulus payment was authorized by Congress. The three Economic Impact Payments (2020, 2021, and 2021) were the only federal stimulus checks issued during the pandemic. Some states issued their own payments to residents, but these were separate from the federal program and varied by state.
