UK tax calculators
Seven tools, updated for the 2026/27 tax year. Every figure updates as you type — nothing is submitted anywhere and nothing is stored.
A caveat worth reading
A calculator cannot see your whole position.
These tools assume a straightforward set of circumstances. They do not know about your pension contributions, other income, benefits in kind, capital allowances, losses brought forward, marriage allowance, or the fact that you own a second company. Any one of those can change the answer materially.
Use them to get oriented and to sanity-check what you have been told. Then have the conversation.

Answer a few questions about your business and get a fixed monthly quote back — or book a call and talk it through first.
