If you’re still waiting for your money from the second stimulus check — or even the first — and the IRS doesn’t normally require you to file a tax return, you may need file one this year to claim money you are eligible for. That would put you in a group of up to 8 million non-filers who aren’t typically required to file a tax return but who didn’t get a second stimulus check they may have qualified to receive.

To address these missing payments, President Joe Biden has signed an executive order asking the Treasury Department to consider making it easier for this group of non-filers to receive their second payments of up to $600 per person. While it’s not clear how the Treasury will respond to the request, with tax season about to start, the easiest way for non-filers to claim their money may be to actually file 2020 taxes this year, using the IRS’ Recovery Rebate Credit.

Below, we walk you through everything you need to know, including why your second stimulus check may be missing (a direct deposit mistake, change of home address, a child dependent wasn’t counted, accidental garnishment?) and which steps you need to take. (In some cases, you’ll have to request an IRS Payment Trace.) As a general rule, many non-filers received a second stimulus check automatically and will likely get a potential third stimulus check, too. In addition, here’s why you want to file your tax form as soon as possible. This story is frequently updated.

What does non-filer status mean? What usually happens at tax time?

When it comes to stimulus checks, the IRS refers to people who didn’t have to file taxes in 2018 or 2019 as non-filers. This group includes:

• People who are part of the SSI or SSDI programs
• Single people under age 65 with an income of less than $12,200
• Married people under age 65 with an income of less than $24,400
• Single people age 65 or older with an income of less than $13,850
• Married people age 65 or older with an income of less than $27,000
• Veterans and Railroad Retirement beneficiaries

While young adults age 17-24 who are claimed as dependents on someone else’s taxes don’t have to file taxes, they aren’t eligible for a first or second stimulus check due to the rules set out in the CARES Act and the December stimulus bill. Find out more about when you can receive your own stimulus check here.

Typically during tax season, if you’re included in any of the above groups, you don’t have to file a federal tax return. However, if you received any health care tax credits or subsidies, you’ll need to file to keep receiving them. You can also still file to get back any taxes withheld from your pay, or to claim certain refundable tax credits. That’s what you’re going to have to do this year to claim your missing stimulus money.

Are non-filers eligible to receive stimulus checks?

In most cases, yes. Most non-filers fall below the income limits stipulated by each stimulus package and would be eligible for the full amount in each round — $1,200 per person under the 2020 CARES Act passed in March 2020, and $600 per person under the December 2020 stimulus bill. Find the full eligibility rules for each stimulus check here.

If you receive SSI or SSDI, you should have received at least a portion of both of those stimulus checks automatically — the IRS obtained the names of Social Security recipients and SSI beneficiaries from the Social Security Administration in the spring and made the payments to them automatically, according to Janet Holtzblatt, a senior fellow at the Urban-Brookings Tax Policy Center.

However, if either of your checks (or a portion of either) are missing, you’ll have to take the extra steps below.

How do non-filers claim a missing stimulus payment? Is it free?

In the first round of stimulus checks, the IRS sent letters to 9 million non-filers with information on how to file a claim to get their missing stimulus money. The agency instructed non-filers to use the non-filers tool to enter their information by Nov. 21. But if you missed the deadline, you can still claim your money as a Recovery Rebate Credit by filing a 2020 federal income tax return — even if you usually don’t have to:

When you file a 2020 Form 1040 or 1040SR you may be eligible for the Recovery Rebate Credit. Save your IRS letter – Notice 1444 Your Economic Impact Payment – with your 2020 tax records. You’ll need the amount of the payment in the letter when you file in 2021.

If you did use the IRS non-filers tool, you should have automatically received a second payment. If you didn’t, you can still file for that money as a Recovery Rebate Credit as well.

File for your Recovery Rebate Credit as part of a federal tax return this year, even if you don’t normally do so. The IRS said it will start processing 2020 tax returns on Feb. 12, and federal tax returns are due April 15. (In 2020, the IRS extended the deadline to July 15 as a result of the COVID-19 pandemic).

To get started, most non-filers are eligible to use the IRS’ Free File tool (if you make less than $72,000 a year, you can use it). As the name suggests, this tool lets you obtain a free federal tax return and in some cases a free state return as well. It’s available to use now.

Go to the Free File site and select Choose an IRS Free File Offer to see all of the options available, which include companies like TaxSlayer and TurboTax. These programs should walk you through how to file your return and the Recovery Rebate Credit Form 1040 or Form 1040-SR, all with no costs or fees.

What’s a Recovery Rebate Credit? How much money should I expect to get?

A Recovery Rebate Credit is a tax credit that will either increase the amount of your tax refund or decrease the amount of tax you owe, based on how much of your stimulus funds the IRS still owes you.

File for your missing money from the first and/or second stimulus on the 2020 Form 1040 or Form 1040-SR. The tax return instructions include a worksheet to figure out the amount of any Recovery Rebate Credit for which you’re eligible, according to the IRS. However, this worksheet requires you to know the amounts of your stimulus payments. CNET’s stimulus check calculators for the second and first payments can provide an estimate.

Find out the IRS’ official total for you in two ways:

• IRS letters: You should have received IRS Notice 1444 for the first stimulus payment, and you should receive Notice 1444-B for the second. Hold onto those letters, because you’ll need the information for the Recovery Rebate Credit worksheet or any tax preparation software you use. If you lost the letters, here’s what to do.
• Your online tax account: In the coming weeks, if you have an account on IRS.gov/account, you’ll be able to log in and see the amounts of the stimulus payments you were allotted.

How soon will my stimulus could payment arrive after I file for a Recovery Rebate Credit?

Since the IRS said it will start processing 2020 tax returns on Feb. 12, it’s likely the government would begin sending out Recovery Rebate Credit payments shortly after that, depending on how early you file. The IRS recommends filing electronically and entering your direct deposit information as soon as possible to speed up your payment.

If you file for a Recovery Rebate Credit with the IRS Free File tool, but don’t give the IRS your banking information, your money will arrive on a paper check in the mail. Just know this option will take longer. Giving the IRS your direct deposit information may also help you receive the next stimulus check faster.

After you file, use the IRS Where’s My Refund? tool to track your payment.
