What Is a Tax Jurisdiction?
A tax jurisdiction is a territory or authority with legal power to levy taxes on persons and income connected by residence, source or citizenship.
Also known as: Taxing jurisdiction, Fiscal jurisdiction.
How Tax Jurisdiction works
A tax jurisdiction is a country, state, canton or other public authority which may impose tax, and the jurisdiction's reach over a given person or income generally depends on a connecting factor such as residence, the source of income, the location of property or, in a few systems, citizenship. UK guidance states that residents normally pay UK tax on all income, whether from the UK or abroad, while non-residents pay UK tax only on UK income. The United States also taxes citizens and resident aliens living abroad on worldwide income from all sources, so one person may fall within several tax jurisdictions at once. Overlapping claims are generally resolved through double tax treaties, foreign tax credits or domestic relief, and sub-national authorities may add their own layer.
Tax Jurisdiction vs Tax Residency
Unlike tax residency, which is a personal status under one country's rules, a tax jurisdiction is the authority or territory levying tax, and one person may fall under several jurisdictions simultaneously.
Example
Illustrative example: A US citizen lives in Country A and earns consulting fees from a client in Country B. Country A taxes the citizen as a resident, Country B may tax the fees as the source country, and the United States taxes worldwide income on the basis of citizenship, leaving three jurisdictions with potential claims and relief governed by treaties and credits.
Common misconception
Myth: Leaving a country automatically removes that country's tax jurisdiction over all income.
Reality: A country may keep taxing a former resident on income sourced there, on certain assets, or on the basis of citizenship, subject to local rules and applicable treaties.
