2
Complete the tax wizard
TaxPilot asks smart questions about your income sources: PAYE, rental, SAYE, Airbnb, freelance. 2 minutes.

Drop in your P60 PDF (even password-protected). AI extracts gross pay, tax, NI, tax code, employer in seconds.

Privacy & trust

Do we see your data?
Here's exactly what happens.

We're going to be completely transparent. Tax data is sensitive — you deserve to know precisely what TaxPilot can and cannot see.

🔒 Stays on your device only

We never see this

This data is stored in your browser's local storage (Chrome). It never leaves your device. TaxPilot's servers have zero access.

Your HMRC username & password — we only activate on HMRC pages, never capturing credentials
Your P60 PDF — processed entirely in your browser using PDF.js; the file itself is never uploaded
Your tax records, receipts & documents — stored locally in chrome.storage.local
The contents of your HMRC screen — page context is only used to give you relevant answers, never logged
Your NI number — extracted from P60 but stored locally only
🤖 Sent to the AI (Gemini)

What the AI sees

When you ask a question or the AI analyses your page, a summary of your tax figures is sent so it can give you relevant, personalised answers.

Your name & income sources (e.g. “PAYE + Airbnb rental”) from your profile
Key figures extracted from your P60 (gross pay, tax deducted, tax code) — not the document itself
Tax totals you've entered (rental income, CGT proceeds) — the numbers, not source docs
The HMRC page type you're on (e.g. “Employment page”) so answers are relevant
Your questions in chat — conversation history is stored locally and cleared when you log out
🌐 Goes to TaxPilot's server

Our backend receives

Our server handles authentication and billing only. It does not process or store your tax data.

Your Google account email — for sign-in and account management only
Your subscription status — to validate your plan and authenticate AI requests
Your referral code (if you used one) — to credit the person who referred you
Nothing else. No P60 data, no tax figures, no documents, no HMRC session.
💬 How to think about it
“It's like giving your accountant a one-page summary sheet of your finances — not handing them a box of your bank statements and P60s. Your documents stay in your filing cabinet (your device). The AI just gets the key numbers it needs to help you.”
🔒
Your device
P60 PDF, raw documents, HMRC session, NI number, tax records — stays here forever
