Territorial taxation

Territorial taxation starts with a source question: is this income connected closely enough to this country to be taxed there? It contrasts with worldwide taxation, where residents are generally taxed on income wherever it arises. But the contrast should not be exaggerated. Most real systems are hybrids, with different source rules for employment, business profits, dividends, interest, property, and capital gains.

The practical mistake is to focus on the customer's location or the company bank account. For service income, many countries look first at where the work is performed. If you live in the country and write code, advise clients, or negotiate contracts there, calling the client or company “foreign” may not prevent local tax. It can also create payroll duties or a permanent establishment for the company.

Foreign investment income needs its own analysis. A jurisdiction may exempt some foreign dividends, tax gains on locally situated assets, tax foreign income when remitted, or impose reporting even where no current tax is due. Anti-avoidance rules can attribute income from a controlled foreign company back to a resident owner. Treaty rules may reduce withholding before the income reaches you, but they do not create a blanket exemption.

Use the term as a starting point, not an answer. Map each income stream, identify where the underlying activity and asset sit, then check the resident and non-resident rules separately. This is particularly important for founders: a country's territorial rules for an individual do not automatically protect a foreign operating company managed from the country.
