Real accountants.
Real responsibility. Real guarantees.
TaxRoot is a UK HMRC-authorised accountancy firm with a product team. Every Self Assessment, CT600, MTD filing, and Companies House submission is handled by a named, UK accountant — backed by software that keeps deadlines visible and documents organised.
Why TaxRoot exists
“Every founder I knew was paying too much for too little.”
TaxRoot started in 2024 after a simple observation: the UK has world-class accountants, but the good ones were expensive, hard to reach, and billed by the hour. The cheap ones used spreadsheets, disappeared for weeks, and quietly added “admin fees” at filing time.
For a first-time founder — sole trader, Ltd director, or side-hustler — neither option worked. You needed a real UK accountant, real compliance cover, and a real platform that told you what was due and when. At a price you could budget.
So we built TaxRoot: an HMRC-authorised firm with a modern client platform, flat fees, and a Penalty-Free Filing Guarantee. Every filing is done by a named, UK accountant. Every price is published. Every deadline is tracked for you.
Our mission: make the compliance side of running a UK business completely quiet — so you can spend your attention on the part only you can do.
What we stand for
Four non-negotiables.
HMRC-authorised, always
We hold an active Agent Services Account and Companies House registration. Your filings go through a real regulated agent, not a marketplace.
Humans first, software second
The platform is fast because the accountants behind it are fast. No chatbot triage, no offshore relays — a UK accountant owns your work.
Priced for founders, not hourly
Flat fees you can plan around. If your turnover grows, fees only change at the start of your next year. No surprise invoices, ever.
Penalty-Free Filing Guarantee
If we miss an HMRC or Companies House deadline through our error, we pay the penalty. You focus on building; we carry the compliance risk.
