The second stimulus check is already being sent out to tens of millions of eligible Americans who qualify for the payment of up to $600 per adult and child dependent. If you receive SSI or SSDI — short for the Supplemental Security Income or Social Security Disability Insurance programs — the IRS has said you should automatically be eligible to receive the second stimulus check.

Just days after the new checks were signed into law in December, the IRS and Treasury began making payments through direct deposit, paper check and EIP card. (Here’s how to estimate your second stimulus check total, the IRS’ stimulus check formula and how to know which stimulus payment group you’re in.)

But what about the talk in December of $2,000 payments? Those are not happening, as of now, but there is a chance that a third stimulus check could potentially happen in early 2021. But until that discussion, here’s what you should know about how SSI and SSDI affect the second stimulus check. This story was updated with new information.

SSI, SSDI and second stimulus payment eligibility

The question of who will qualify for a second stimulus payment is mostly the same as for the first round of payments back in March with the CARES Act. That means if you’re part of the SSI or SSDI program, you’d qualify for a check just like you did in the first round, so long as you have a Social Security number and you aren’t claimed as a dependent on someone else’s tax return.

Also, your household income mustn’t exceed the threshold ($75,000 single, $112,500 head of household, $150,000 married). Those receiving Railroad Retirement and Veterans Affairs benefits also should automatically qualify for a payment. Note that because of some fairly complex math in the stimulus check formula, fewer people in general will receive a (smaller) stimulus check this time around.

Do you have to do anything to get your second stimulus payment?

According to the IRS, people who receive Social Security retirement, SSDI, Railroad Retirement benefits and Supplemental Security Income as well as Veterans Affairs beneficiaries are automatically eligible for a payment. The IRS has begun sending payments now and will continue through Jan. 15. After that point, you’d need to register for a Recovery Rebate Credit as part of this year’s tax season.

What do you do if your first stimulus check is still missing?

If you receive SSI or SSDI but still haven’t gotten a stimulus check from the first round, the IRS may still need more information about your eligibility. To receive your money, you’ll need to claim the additional amount when you file your taxes, using the Recovery Rebate Credit. Even if you don’t usually file taxes, you will have to do so to get those funds.

You can also track the status of your second stimulus check — and the first, if you didn’t receive it. If your second payment doesn’t arrive by the Jan. 15 IRS cutoff date, you will likely have to file for it using a Recovery Rebate Credit.

What if you didn’t file a tax return the last few years?

If you receive federal benefits, including SSI and SSDI, as your only form of income, you weren’t required to file a federal income tax return in 2018 or 2019. Under the CARES Act, you were still eligible to receive a stimulus check, and should’ve received one automatically (no need to file a simple tax return, as the IRS had originally said).

How will your stimulus money be delivered to you?

Most SSI and SSDI recipients didn’t receive their first payments via their Direct Express card, though this is usually what the government uses to distribute federal benefits. Instead, the payment arrived through a non-Direct Express bank account or as a paper check if you didn’t have your bank account information on file with the IRS.

This time around, the IRS says on its website that SSI and SSDI recipients should expect to get their stimulus check money the same way they receive their first stimulus checks, possibly faster, as the IRS already has the payment system set up. For who received the first round of payments via Direct Express, they will receive this second payment the same way, the IRS said.

If you receive SSI but not Social Security benefits, and did not file for taxes in 2019, the IRS will automatically send your payment the same way you normally receive your SSI benefits, such as by direct deposit, Direct Express card or paper check.

Are your children eligible for the second stimulus check?

As long as your children are 16 years old or younger, they’ll contribute $600 toward the final total of your household’s second stimulus check. You can use our stimulus check calculator to figure your family’s total estimate.

Under the CARES Act, qualified people with dependents age 16 or younger were eligible for up to $500 per child dependent, but not everyone actually received that extra money. The last day to claim your missing payment and receive it in 2020 was Nov. 21. The IRS said that if you missed the deadline, you can claim the missing payment during tax season in 2021. Here’s who the IRS counts as an adult to receive their own stimulus check.

What if you didn’t get your first stimulus payment?

If your first payment didn’t come already and you registered with the Non-Filers tool by Nov. 21, 2020, the IRS says, you should’ve received the payment by now, specifically in December 2020. If you missed the Nov. 21 cutoff, the IRS says, you can receive your payment in 2021 when you file your federal tax return. Here’s what we know about how to track the status of your second stimulus check — and the first, if it’s missing.

Will you get the catch-up money for dependents?

If you used the IRS’ Non-Filers tool from May 5 through Aug. 15 of 2020, the IRS should’ve automatically issued the catch-up payment for your dependents in October. If you received your original stimulus money by direct deposit, you should’ve gotten the catch-up payment the same way. Others would’ve received it in the mail.

If you filed for your missing dependent money by Nov. 21, the payment should’ve arrived by the end of 2020, in the same way you received your first payment (likely direct deposit or by mail). If you missed the deadline, your check will be included on your 2020 tax return in 2021.

To check the status of your or your dependent’s payment, use the IRS’ online tool to track it. You should also get a letter in the mail letting you know that an additional $500 per qualifying child has been issued.

What about SSI and SSDI recipients outside the US?

If you’re a Social Security beneficiary with a foreign address whose monthly benefit is deposited into a foreign bank account, you’ll receive your stimulus payment as a check in the mail. (The IRS isn’t meant to deposit money into foreign banks.) The IRS planned to start sending the first raft of checks to those recipients at the end of July 2020. If you live abroad but receive your monthly benefits through a US bank, you should’ve received your first payment by direct deposit to that account by the end of July as well. It isn’t clear what will happen to this group with the second check, but if it isn’t distributed by Jan. 15, it will have to be claimed as part of a tax return.
