For most tax returns, the answer is no. Our e-filing "window" for non-corporate and non-partnership returns goes from January to mid-October of the calendar year that immediately follows the tax year.
For example, tax year 2020 returns can be e-filed from January 2021 through October 2021.
After e-filing shuts down for the current tax year, we're working hard to get things ready for the upcoming tax year.
If you still need to file your 2018, 2019, or 2020 tax return, see these instructions for paper-filing your return.
