Deadlines for annual returns are almost invariably in the spring, with extensions available until the fall:
- Individual income tax returns: April 15 falls on a weekday in 2021, and it's not a holiday this year, so the filing deadline for your 2020 personal tax return is indeed April 15, 2021.
- Estimated tax payments for the 2020 tax year (IRS Form 1040): For 2020, the first and second payments were both due on July 15. Third quarter was due October 15th. The fourth and final estimated payment for the 2020 tax year was due on Jan. 15, 2021.
