Provinces & states

Canada

All 10 provinces and 3 territories have 2025 regional income-tax estimates. Assumes single, under 65, no dependants. Some low-income credits and payroll adjustments are excluded; use the calculator’s formula panel to see the assumptions.

United States

All 50 states and DC have a 2025 wage income-tax formula. Nine states correctly show no state income tax on wages. State deductions, exemption rules and selected surtaxes are included. Local taxes, payroll taxes and some credits are excluded.

Every state and DC now has an actual FY2024 spending breakdown from the U.S. Census Bureau. Pick a state in the calculator to see your state tax split across Medicaid, schools, universities, highways, prisons and more.

United Kingdom

England, Wales, Scotland and Northern Ireland remain selectable. Scottish employment-income rates are handled in the national calculation. Separate devolved and local spending models are not validated.

Australia and New Zealand

All eight Australian states and territories and New Zealand’s 16 regions are selectable. Neither country levies state or regional income tax, so the result is the national estimate only. Spending shares use Australian Government general government expenses for 2024–25 (Final Budget Outcome, Table A.1) and New Zealand core Crown expenses for the year ended 30 June 2025 (Treasury).
