Tax Calculators
Five calculators for the questions we are asked most. Where the rates differ between years, you can choose 2025/26 or 2026/27.
- Salary vs DividendsFor a director-shareholder: what different salary levels leave in your pocket once Corporation Tax, employer NI and dividend tax are all accounted for.
- Corporation TaxIncluding Marginal Relief and the associated companies rules, with the effective rate you are actually paying.
- Take-Home PayIncome tax and National Insurance on a salary or on self-employed profits, including the 60% band above £100,000.
- CIS DeductionsConstruction Industry Scheme deductions at 20% or 30%, calculated on the labour element only, with the reverse charge handled.
- VATAdd VAT to a net figure or strip it out of a gross one, at standard, reduced or zero rates.
How to use these sensibly
Each calculator makes assumptions, and each says what they are. They are built to give you a reliable order of magnitude and to show you where the thresholds bite — not to replace a computation.
The Corporation Tax and salary calculators in particular assume a straightforward company with no associated companies and no Employment Allowance. Both of those change the answer materially, and both are common.
A calculator tells you what the rules do. It cannot tell you what you should do.
When they are updated
Rates change every April, and sometimes in between when a Budget lands. Every calculator here states the tax year it applies to and the date of its next review. If you are reading one after April 2027 and it still says 2026/27, treat the figures with caution and check with us.
Real tax computations involve capital allowances, losses, pension contributions, other income, and the structure you trade through. That is the work, and it is where the savings actually are.

These calculators give general estimates and are not a substitute for advice on your own circumstances. Figures apply to England, Wales and Northern Ireland; Scottish income tax rates differ.
