October Extended Due Date Just Around the Corner

Article Highlights

The IRS extended the normal April 15, 2021 filing deadline for 2020 individual tax returns to May 17, 2021, due to the continuing Covid-19 pandemic. If you could not complete your 2020 tax return by May 17 and are now on extension, that extension expires on October 15, 2021. Failure to file before the extension period runs out can subject you to late-filing penalties.

There are no additional extensions (except in designated disaster areas). If you still do not or will not have all of the information needed to complete your return by the extended due date, please call this office so that we can explore your options for meeting your October 15 filing deadline.

If you are waiting for a K-1 from a partnership, S-corporation, or fiduciary return, the extended deadline for those returns is September 15 (September 30 for fiduciary returns). So, you should probably make inquiries if you have not received that information yet.

Late-filed individual federal returns are subject to a penalty of 5% of the tax due for each month or part of a month. A return that is not filed, up to a maximum of 25% of the tax due. If you are required to file a state return and do not do so, the state will also charge a late-file penalty. The filing extension deadline for individual returns is also October 15 for most states.

In addition, interest continues to accrue on any balance due, currently at the rate of 3% per year. This rate is subject to adjustment quarterly.

Suppose this office is waiting for some missing information to complete your return. In that case, we will need that information at least a week before the October 15 due date. Please call this office immediately if you anticipate complications related to providing the required information to determine a course of action to avoid the potential penalties.

Additional October 15, 2021 Deadlines

In addition to being the final deadline to timely file 2020 individual returns on extension, October 15 is also the deadline for the following actions:

FBAR Filings

Taxpayers with foreign financial accounts, the aggregate value of which exceeded $10,000 at any time during 2020, must file electronically with the Treasury Department a Financial Crimes Enforcement Network (FinCEN) Form 114, Report of Foreign Bank and Financial Accounts (FBAR). The original due date for the 2020 report was April 15. Still, individuals have been granted an automatic extension to file until October 15, 2021.


October 15, 2021, is the deadline for a self-employed individual to set up and contribute to a SEP-IRA for 2020. The deadline for contributions to traditional and Roth IRAs for 2020 was May 17, 2021. Usually, the deadline is April 15 for IRA contributions for the prior year. Still, for 2020 contributions, it was extended a month because of the Covid-19 crisis. May 15 was a Saturday, so the due date was the next business day, the 17th.

Special Note—Disaster Victims

Suppose you reside in a Presidentially declared disaster area. In that case, the IRS provides additional time to file various returns and make payments.

Please call this office for extended due dates of other types of filings and payments and extended filing dates in disaster areas.
