Every year, millions of people stare at cryptic tax forms with no idea what to enter. The January panic is real.
HMRC's forms use jargon that even experienced filers find confusing — finance cost restrictions, underpaid tax in coding, payments on account...
For straightforward returns, that's expensive. Most people just need someone to tell them what number to type into which box.
ChatGPT doesn't know your tax code, your Airbnb income, or your SAYE shares. Generic answers don't help you file with confidence.
Over 5 million people file in the last week of January. HMRC's helpline has hours-long queues. There's no one to ask.
TaxPilot is a Chrome extension that lives alongside the portal as you file — no switching tabs, no copying numbers.
Add TaxPilot from the Chrome Web Store. Enter your tax code, income sources, and any notes. Takes 2 minutes.
Go to tax.service.gov.uk as normal. TaxPilot automatically injects a sidebar on the right side of every HMRC page.
As you move through your return, TaxPilot reads each page and tells you exactly what to enter — and why. Ask follow-up questions in the chat.
Submit your return knowing every box was filled correctly. TaxPilot spots HMRC error messages and explains how to fix them.
Built specifically for the complexity of UK Self Assessment — not a generic tax chatbot.
TaxPilot reads the exact HMRC page you're on — form fields, hints, and error messages — and responds in context.
Set up your tax code and income sources. TaxPilot uses your actual situation, not generic examples.
Knows about the Section 24 mortgage interest restriction, co-ownership splits, and the abolished FHL regime from April 2025.
Understands CGT treatment of Sharesave, EMI BADR rates, and unapproved options — and tells you exactly what to enter.
Switch between profiles in one click. Perfect for couples with shared property income who file separately.
When HMRC throws a validation error, TaxPilot explains what it means and tells you exactly how to fix it.
