Tax calculator limitations

The tax calculator gives an estimate for a supported country, region and tax year. It is not professional tax advice.

Currently supported: - United Kingdom (England, Wales and Northern Ireland) — 2026/27 Income Tax and employee National Insurance

Not included: student loans, pension salary sacrifice, benefits in kind, Scottish rates, and other personal circumstances. Where we don't have verified rules, the calculator shows that the jurisdiction is unavailable instead of producing a number.
