Back Taxes, File Previous Tax Returns

Since January 2021, taxpayers are able to prepare and eFile 2020 IRS and state income taxes. For all previous year or back taxes, find the tax forms on your eFile account and below as well. You can complete and sign the forms before you download and mail them to the IRS mailing address or state tax agency—state mailing addresses are listed on individual state pages. Be sure to use the previous year mailing address and not the current mailing address to be sure your previous year return goes to the right place.

If you have to file a prior year return, forms are listed below by tax year. Mail in the return(s), but do not expect fast processing of the submitted forms. Remember, prior year tax returns cannot be electronically filed anywhere. In order to claim any of the stimulus payment checks, learn on what you need to do. For example, for stimulus check 1 and 2, you might have to eFile your 2020 Tax Return and claim the Recovery Rebate Credit for missed stimulus payments or your full 2020 Tax Return. If you miss filing your 2020 return to claim a missing stimulus payment - only for stimulus 1 and 2 - you will have to file back taxes which will not be able to be e-filed after October 15, 2021.

The timely tax filing and efile deadlines for all previous tax years—2019, 2018, and beyond—have passed.

eFile.com Tax Ideas

Important efile.com Tax Tip: In case you have not filed a previous year tax return, do this as soon as possible and download the forms below. Why? The late filing penalty (5%/month of the tax amount owed, plus interest) is usually larger than the late payment penalty (0.5%/month, plus interest). Again, file you return and pay as little or as much as you can afford, or even nothing. Doing so will result in the higher filing penalties stopping once you have filed.

We provide all the forms, tax calculators, and tools for previous year tax returns below. Plus, you can contact one of our Taxperts to assist you with your previous year tax returns or tax amendments. In certain cases, we work interactively with taxpayers and our CPA can prepare your previous year tax return with you.

Additional Information: A tax year is from January 1 - December 31 for any given year. A tax season (prepare and e-file returns for the previous calendar or tax year) is from January 1 until October 15 of any current year. During any current tax season or calendar year, a timely tax return would be prepared and e-filed for the previous calendar year. To put it simply: during January 1, 2021 - April 15, 2021, you prepare and e-file taxes for the tax year of 2020. There are extensions if the taxpayer is unable to file by the date which can extend the deadline to October 15.

One more Awareness Tip: Should you expect a tax refund for a previous year tax return, you practically don't have to worry about penalties. Be aware that you can only claim your tax refund for a previous tax year within three years of the original tax return's due date or deadline. For example, you have until April 15, 2024 to claim a 2020 Tax Refund, April 15, 2023 to claim 2019 Tax Refund, for 2018 until April 15, 2022, and 2017 until April 15, 2021. For all other back taxes or previous tax years, it's too late. See information about unclaimed refunds for details. Unfortunately, if you owe taxes, there is no time limit; this is only if you expect a tax refund.
