About UK Finance calculators
The take-home pay calculator applies the £12,570 personal allowance (tapered above £100,000), the 20%, 40% and 45% bands, employee National Insurance and a pension contribution. The National Insurance calculator shows both the employee and employer shares. Employer NI is 15% above £5,000 a year.
The capital gains tax calculator applies the £3,000 annual exempt amount and the 18% and 24% rates according to your income band. The stamp duty tool uses the English and Northern Irish bands, first-time buyer relief and the 5% higher-rate surcharge for additional properties.
Understanding UK tax in 2026/27
The take-home pay calculator applies the personal allowance, income tax bands and National Insurance in one step. Add a pension percentage to see how contributions reduce tax. Use the National Insurance Calculator for employer costs.
Property buyers should run the stamp duty calculator before bidding because the first-time buyer relief and the additional property surcharge change the bill significantly. Investors can estimate disposal tax with the capital gains tax calculator.

Frequently asked questions
Which tax year do the UK tools use?
2026/27 for income tax, National Insurance and capital gains tax, and the stamp duty rates in force from April 2025. Rates for Scotland and Wales differ.
Are these calculators official?
No. They are estimates. Check GOV.UK or HMRC for the final figure.
Do these tools cover Scotland and Wales?
Income tax in Scotland has different bands, and Wales and Scotland have their own property taxes. These tools use the rest-of-UK rates.
Are UK thresholds frozen?
The personal allowance and higher-rate threshold are frozen until April 2031 under current plans, so more income falls into higher bands.
