It’s not too late to file a tax return to claim your missing stimulus money! The IRS extended the tax-filing deadline to May 17, 2021. Even after the deadline, you can still file to claim your money! If you do not owe any Federal taxes, then you can file your return after the deadline without a penalty - in fact, you have 3 years to claim your refund.
