Check whether the IRS owes you a refund from a year you didn't file

If you didn't file a return in a year when tax was withheld, you may be owed a refund, but only for about three years.

1. Copy this prompt

Paste it into ChatGPT, Claude, Gemini or Grok (the free versions work), then replace the [highlighted brackets] with your details. Leave out account numbers and SSNs.

I didn't file federal tax returns for [YEARS]. In those years I worked at [JOB TYPE] and had about $[INCOME] in income with federal tax withheld (from W-2s or transcripts). 1) Tell me which years are still within the IRS deadline to claim a refund, and how the deadline works. 2) List the forms and documents I need for each year. 3) Tell me which credits I should check (like the EITC) based on my situation. 4) Explain why a refund might be held (for example, other unfiled years) and what to do. Point me to IRS pages to confirm.

What to expect, and what to do if they say no

What to expect

  • Paper returns for prior years can take several months to process.

If they say no

  • Ask a free VITA (free IRS-backed tax help for people with lower incomes) site to help prepare prior-year returns.
  • Call the IRS if a refund is held or offset.

What happened when people tried it

  • We haven't verified a real-world example for this one yet, so it's a tool guide plus a prompt. Tried it? Tell us what happened (link below).

Why this works

The problem: People with low income, part-time jobs or students often skip filing, not realizing tax was withheld and they're owed money back.

How AI helps: AI can check which years are still claimable, explain which forms you need, and help you gather old W-2s and 1099s through your IRS online account.
