Connect HMRC and pre-fill everything
One secure connection pulls your tax record into AI TaxPilot — and pre-fills every calculator and wizard, with each figure tagged to its source.
Connect HMRC
Sign in with your Government Gateway. HMRC hands us a scoped, revocable token — we never see your password, and you can disconnect any time.
Step by step
The same journey, written out — so you can read it at your own pace.
- Connect HMRC
Sign in with your Government Gateway. HMRC hands us a scoped, revocable token — we never see your password, and you can disconnect any time.
- We pull your record
Identity, employments, income and the tax you’ve already paid — imported securely from HMRC and held against your profile.
- Figures flow everywhere
Your record doesn’t just sit in one screen — it pre-fills the Income Tax and Take-Home calculators, the Self Assessment wizard and your Tax Health score.
- Every field, tagged & editable
Pre-filled boxes carry a chip showing exactly where the number came from — HMRC, your bank or your profile. Override anything in a tap.
Common questions
What exactly can you see?
Only the read scopes you approve at HMRC — identity, income and tax paid. We can’t change anything at HMRC through this connection, and you can revoke it whenever you like.
I pay tax in the UK and the US — does that matter?
No. You can connect HMRC and (where available) the IRS independently; each only pre-fills the relevant parts of the app.
Import once, use everywhere
Connect HMRC and watch your figures pre-fill every calculator and return — each one tagged to its source.
Connect HMRCThis guide is general information, not personal tax advice, and reflects the rules we believe to apply as at June 2026 — rates and thresholds change. Always check your own figures against HMRC and consider a qualified adviser before acting. You remain responsible for the accuracy of anything you file.
