How our calculators work
Each calculator applies the rates that our tax team has entered and approved for a specific tax year (the current one is tax year 2026-2027, which runs from 1 July 2026 to 30 June 2027). When the law changes, the old rates are kept for earlier years and the new ones are added as a separate version, so a result for a past year does not change.
- You see the working. Salary and business results include a slab-by-slab breakdown, so you can follow how the figure was reached.
- You see the source. The law the rates come from and the date they were last verified are printed next to every result and on the PDF.
- Nothing is stored. The figures you type stay in your browser. We do not save them or send them to analytics.
The results are estimates. They cannot take account of exemptions, tax credits, tax already deducted or other income you may have, and they are not tax advice.
