Step 1 of 4

Free multi-year scan

See what you overpaid.

Connect your bank, we read your last two years, then show deduction suggestions for your review - so you stop overpaying the IRS.

Free if you earned under $100,000. That is most gig workers. $99 above.

We send your results here and hold your spot. No spam.

A few quick things

Your driving.

California today. More states as the engine learns them.

Usually the biggest write-off, and the one your bank can\'t see. Not sure? Most full-time drivers log 20,000 to 40,000. Leave it blank if you have no idea.

Last step

Connect your bank.

We read two years of transactions to find your write-offs. About a minute.

  • Plaid — the same secure link your banking apps use.
  • Read-only. We can never move your money.
  • Your password is never shared with us.

Sandbox bank connect: pick any bank, then sign in with user_good / pass_good (code 1234 if asked).
