As reported by the Government Accountability Office (GAO), almost half a million taxpayers did not receive their full payment due to complications over distributing the correct funds to non-filers with dependents.

The IRS is working on adjusting amounts for those that received incorrect amounts to make sure they receive what is entitled to them. If you generally do not have to file an IRS Income Tax Return, but you filed a Simple or Stimulus Tax Return in 2020 for Tax Year 2019 as a Non-Filer or Social Security Income Recipient and did not claim a qualifying dependent (or you did for other reasons, but did not receive the stimulus payment amount you think you were entitled to), you might have to file another tax return in 2021 for Tax Year 2020 in order to claim this dependent and/or adjust your 2020 Stimulus Payment.

All other taxpayers who generally file tax returns and their stimulus payments did not reflect dependents or other information in the payment amounts can adjust this with their 2020 Tax Returns due on tax deadline April 15, 2021.

If your simple return has been accepted and you want to make a change to this simple return, please prepare a tax amendment now. If the IRS does not accept this amendment, file a 2020 Tax Return here on eFile.com in 2021.

Tip: Add a letter and explain why you are filing this amendment. In the Explanation part of the amendment, report that you mistakenly did not include dependents on your filed return. For more questions about your stimulus payment amount, call the IRS for the status of your Economic Impact or Stimulus Payment at 1-800-919-9835.
