Election watch

Next general election: during the current parliamentary term, which began in 2024.

Parliament can run for up to five years; an earlier election can be called. No exact next polling day is claimed here.

Checked 2026-09-17. Selected government and party sources; 2024 manifestos are historical, not next-election promises.

Government and alternative plans

Source documents for reference. A party's costing is its own estimate unless identified as independent. Different years, definitions and government levels are not directly comparable. These documents do not automatically change the simulator.

Tax starting points

Income tax: 20–45% · Scotland differs
Corporation tax: 19% small / 25% main
VAT / sales tax: 20% VAT
Tariffs: Rates depend on the product, origin and trade agreement.

England, Wales and Northern Ireland non-savings marginal rates for 2026/27 after allowances. Scotland sets different non-savings bands. Corporate small-profits relief and associated-company limits apply.

Tax sources checked 2026-09-17. These are headline references; marginal rates apply to income bands, not every unit of income. Payroll contributions and allowances are not included in this compact comparison.

Income tax source · Corporation tax source · WTO tariff schedules

Pension schedules still marked “Not yet verified” are missing verified comparison data, not countries without pensions. Pension entitlements depend on contributions, age, residence and scheme.
