- October 15 extended due date for filing federal individual tax returns for 2019.
- Late-filing penalty.
- Interest on tax due.
- Other October 15 deadlines.
Because of the COVID-19 pandemic emergency, the IRS postponed the original due date for filing 2019 returns to July 15, 2020. If you could not complete your 2019 tax return by July 15 and filed a request for additional time to file, that extension expires on October 15, 2020. Failing to file before the extension period runs out may cost you late-filing penalties.
