Frequently Asked Questions

The IRS only issues refunds for returns filed within three years of the original due date. For example, if your 2021 business return was due in April 2022, the final deadline to claim a refund was April 2025. After that, any unclaimed refund is forfeited. 

  Please note: TaxAct does not support filing returns for tax year 2022 or earlier. To file older returns, you’ll need to download forms from irs.gov and file by mail.
