Stop Guessing What You Owe HMRC.

Know your Exact Number.

Every year, thousands of sole traders and self-employed people pay more tax than they owe or face HMRC penalties they never saw coming because they had no clear picture of their tax position until it was too late.

This does not have to be you.

Our tax calculators do two jobs at once.

1. Track your income and expenses throughout the year - building a complete HMRC compliant bookkeeping record as you go.

2. Then calculate your exact tax bill from those records automatically - income tax, Class 4 NI, student loan & payment on account

Your real number, months before January.

No accounting software. No Monthly fee. No accountant needed in January. Just a software you already know how to use.
