Understanding UK tax can be complex, with multiple taxes affecting individuals and businesses throughout their financial lives.

Our free tax calculators are designed specifically for UK taxpayers, using the latest HMRC rates, thresholds, and regulations for the 2025/26 tax year.

All calculators are updated immediately following Budget announcements and reflect the significant changes introduced in recent Budgets, including increased employer National Insurance, reduced CGT and dividend allowances, and frozen income tax thresholds that continue to affect taxpayers through fiscal drag.

UK Income Tax Rates 2025/26

Income tax is the most significant tax for most UK workers. The rates for England, Wales, and Northern Ireland are set by the UK government, while Scotland sets its own rates with more granular bands. Understanding which band your income falls into is essential for tax planning.

Scottish Income Tax Rates 2025/26

Scotland sets its own income tax rates and bands, which differ from the rest of the UK. Scottish taxpayers have six bands compared to the rest of the UK's four, with different thresholds and rates. Your tax code will show 'S' if you're a Scottish taxpayer.

National Insurance Contributions 2025/26

National Insurance is a social security contribution that funds state benefits including the State Pension, NHS, and unemployment benefits. Both employees and employers pay NI, though at different rates. The 2025/26 tax year saw significant changes to employer NI rates and thresholds.

Capital Gains Tax Rates 2025/26

Capital Gains Tax is payable when you sell or dispose of an asset that has increased in value. The annual exempt amount has been significantly reduced in recent years, meaning more people now need to pay CGT on their investments and property sales.

Annual Exempt Amount: The CGT annual exempt amount for 2025/26 is just £3,000, reduced from £6,000 in 2024/25 and £12,300 in 2022/23. This means even modest gains may now be subject to tax, making careful record-keeping essential.

Dividend Tax Rates 2025/26

Dividends from shares are taxed at different rates to other income, and receive a separate tax-free allowance. The dividend allowance has been significantly reduced, increasing the tax burden on shareholders and company directors who pay themselves through dividends.

Value Added Tax (VAT)

VAT is a consumption tax charged on most goods and services. Businesses with taxable turnover above £90,000 must register for VAT and charge it on their sales. Understanding VAT rates and calculations is essential for both businesses and consumers.

Corporation Tax 2025/26

Limited companies pay corporation tax on their profits. The rate depends on the level of profit, with a marginal relief system for companies with profits between £50,000 and £250,000.

Inheritance Tax (IHT) 2025/26

Inheritance Tax is charged on estates above the nil-rate band when someone dies. Careful estate planning can significantly reduce or eliminate IHT liability.

Married couples and civil partners can combine their allowances, potentially leaving up to £1,000,000 tax-free (£325,000 + £175,000 each). The residence nil-rate band tapers for estates over £2 million, reducing by £1 for every £2 over this threshold.
