About the UK version
The UK section combines 2026/27 country-specific calculators for Making Tax Digital, Housing Benefit, Local Housing Allowance, Income Tax, PAYE, National Insurance, State Pension, VAT, property taxes and pensions with useful standard calculators for everyday planning. Statutory results are estimates and should be checked against current official guidance before filing or making binding decisions.
How calculators are prepared
The catalog combines individual calculators with automatically generated calculation templates. Validation is ongoing; publication does not mean every formula has been independently expert-reviewed.
For financial, legal, health or jurisdiction-specific calculations, confirm the assumptions and current rules before relying on an estimate.
