About TaxGo
Tax is thecomplicated bit.TaxGo isn't.
TaxGo was built on a simple belief: a UK Self Assessment shouldn't feel like an accounting exam. Upload your documents, answer what's missing, check the result.
Our mission
From documentsto done.
Every year, millions of UK taxpayers face the same problem: a stack of tax documents and no idea how to turn them into a completed Self Assessment. They either pay an accountant or spend hours with HMRC's forms.
TaxGo solves that. Upload your P60s, dividend vouchers, bank statements — whatever you have. TaxGo reads them, extracts the figures, asks a few plain-English questions about anything it couldn't find, and calculates your tax.
And it's transparent. Every number links back to the document it came from. If something doesn't look right, change it before you approve. You're always in control.
What makes TaxGo different
- 01
Document-first
Most people already have the documents they need — P60s, dividend vouchers, bank statements. TaxGo starts with what you have and works out what's missing, instead of asking endless questions.
- 02
Rules calculate, not AI
AI reads your documents. It never decides your tax. Every number is calculated by a deterministic engine using published rates and rules — the same inputs always give the same result.
- 03
Every number has a source
Every figure on your return links back to the document it came from, so you can see exactly where it originated and how your tax was worked out.
How it works under the hood
AI reads.Tax rules calculate.
AI does
- Identifies documents
- Reads the values
- Spots what's missing
Structured tax rules do
- Validate every value
- Apply UK tax rules
- Build the return
- Calculate your tax
- Prepare it for HMRC
The calculation is deterministic: the same confirmed figures always give the same answer. AI never decides how much tax you owe.
Compared with
An accountant
The usual way
Often hundreds of pounds per return. You still gather the documents and answer the questions, and turnaround can take weeks.
With TaxGo
£49, at your own pace. You keep full visibility of every number, and you approve the return yourself.
HMRC's online forms
The usual way
You need to know which boxes to fill in, type every figure by hand and work through the jargon on your own.
With TaxGo
TaxGo reads your documents, builds the return for you, runs structured checks and explains every question in plain English.
Questionnaire tax software
The usual way
Most still make you type figures from your documents and answer long lists of questions that don't apply to you.
With TaxGo
Upload and TaxGo extracts. You only answer what your documents can't tell us. One flat price.
What we believe
- 01
Simple by design
If something feels complicated, we haven't finished designing it. Every screen and every question is written for clarity.
- 02
Accuracy over speed
We'd rather take an extra second to get a number right. Calculations come from structured rules, and you review everything before you approve.
- 03
Honest about limits
If your situation is too complex for TaxGo, we tell you up front. You're never charged for something we can't handle.
- 04
Private by default
Documents are stored privately and every connection is encrypted. We never sell your data. Ask us to delete it at any time.
