As the tax season approaches, it’s important to know that if you’ve filed your tax returns and realized later that you made a mistake, or forgot to claim some deductions, all hope is not lost. You can fix the error by amending your tax returns.

But there are specific time limits for when you can amend your returns, and failing to do so within these limits could result in penalties or even legal action. Here’s our ultimate guide to time limits for amending your tax returns:

The Deadline: 3 Years from the Due Date

Generally speaking, taxpayers have up to three years from the original due date of their tax return (including extensions) to file an amended federal income tax return using IRS Form 1040X.

For example, if you filed your 2018 taxes on April 15th, 2019 (the original due date), then you would have until April 15th, 2022 (three years later) to file an amended return for that year.

Special Rules Apply in Some Cases

There are some situations where special rules apply and may affect the time limit for filing an amended return. Here are a few examples:

  • If you claimed a bad debt deduction or worthless securities deduction on your original income tax return — generally seven years from when your original income tax return was due.
  • If you failed to report foreign financial assets worth more than $50k; six-year statute of limitations
  • Claiming refundable credits: A separate set of rules applies if claiming one of several refundable credits. In this case amendments can be made up until three years after filing deadline including any extension or two years after paying which ever is latter.

Individual states also have varying statutes related deadlines for state-level amendment

It’s advisable that taxpayers consult with either a licensed CPA or enrolled agent before taking any steps to amend their taxes.
