If you're a non-filer and need to get your third stimulus check, here's what you need to do:
File a tax return: Even if you don't normally file taxes, you'll need to file a tax return to claim the Recovery Rebate Credit for the stimulus payment. The IRS reminds taxpayers who haven't yet filed their 2021 tax returns that they may be eligible for a refund if they file and claim the Recovery Rebate Credit by the April 15, 2025, deadline.
Additionally, you can view the total amount of your third Economic Impact Payment through your IRS Online Account or Letter 6475. This information is needed to accurately calculate your 2021 Recovery Rebate Credit when filing your 2021 federal tax return.
