Filing back taxes is the process of submitting federal income tax returns for past years you missed or did not file on time. Falling behind can happen for many reasons—illness, financial hardship, or simple oversight. However, it’s important to take action to update your tax records, minimize penalties, and avoid more serious consequences like IRS collection actions.
Why Filing Back Taxes Is Important
Ignoring back taxes won’t make them go away. The IRS charges interest and penalties on unpaid taxes, and failure to file can lead to audits, levies, liens, or even criminal charges in extreme cases. Additionally, filing back taxes can help you claim refunds or tax credits you might have missed.
How Did You Fall Behind?
Typically, U.S. taxpayers must file their federal tax returns by April 15th following the tax year. Missing this deadline without filing your return puts your account in delinquency. Over time, penalties and interest increase the amount owed, sometimes substantially.
Step-by-Step Process to File Back Taxes
- Gather documentation: Collect all relevant income records such as W-2s, 1099s, and expense receipts for each year you missed.
- Obtain the correct forms: Download the tax forms for each specific tax year from the IRS Tax Forms Archive.
- Prepare and complete each return: Carefully fill out each tax return, ensuring accuracy to avoid processing delays.
- Calculate amounts owed: Include penalties and interest using tools available on the IRS website or by consulting a tax professional.
- Submit returns and payments: File your back taxes by mail or electronically if the IRS allows. If you owe money, pay in full or apply for an installment agreement through the IRS.
- Keep detailed records: Maintain copies of your returns, payment confirmations, and any correspondence with the IRS.
Example Scenario
Take Sarah’s case: She missed her 2020 and 2021 filings due to medical issues. After IRS notices for unpaid taxes and penalties, she gathered her documents, filed her returns using tax software, and arranged a payment plan since she couldn’t pay the full amount upfront. This brought her tax situation into good standing.

If you:
- Have not filed tax returns for years when your income exceeded filing thresholds
