When to File a Tax Amendment — And When You Shouldn’t

Mistakes happen. Maybe you missed a 1099, forgot a deduction, or reported something incorrectly. But before you rush to amend your tax return — know this:
Not every error needs fixing. Here’s when to amend, and when to leave it alone.

You Should Amend If:

  • You received a new W-2 or 1099 after filing
  • You forgot to claim a large deduction (like vehicle expenses)
  • You filed using the wrong filing status
  • You received IRS notice CP2000 showing unreported income

You Don’t Need to Amend If:

  • You made math errors (the IRS corrects those)
  • You forgot a small deduction that won’t change your refund
  • You filed late but haven’t received a letter yet — speak to a pro first!

How to Amend a Return

You’ll need to file Form 1040-X. But if you had a business return (1120-S or 1065), it gets more complex — and timing matters.
