Territorial Tax System
A tax system that taxes only income sourced within the country and generally exempts foreign-source income of resident companies.
Definition
What it is
A territorial tax system taxes residents only on income that has its source within the territory of the country. Foreign-source income, particularly active business profits earned through foreign branches or subsidiaries, is generally exempt. Hong Kong, Singapore (broadly), Panama, Costa Rica, Georgia, Paraguay, and most of the Gulf operate territorial or quasi-territorial regimes. The United States moved closer to a territorial regime through the Tax Cuts and Jobs Act 2017, which introduced the dividends-received deduction (DRD) for foreign profits but kept GILTI as a backstop.
How it differs from worldwide tax
Under a worldwide regime (the historical US, India, and many Latin American countries), residents are taxed on global income, with credit for foreign taxes paid. Under a territorial regime, the source rule does the heavy lifting: only domestically-sourced income is in scope, and offshore activity falls outside the tax net entirely - subject to anti-abuse rules.
Why founders care
Territorial regimes are extremely friendly to international holding and operating structures. They reduce exposure to home-country tax on foreign profits, simplify dividend repatriation, and avoid the layering of foreign-tax-credit calculations. They are not a free pass: substance, transfer pricing, and CFC rules still apply.
When you'll encounter it
You will weigh territorial systems when choosing a holding-company jurisdiction, when comparing Singapore or Hong Kong against Delaware or India, when planning international expansion through branches, and when assessing how foreign profits flow back to the parent without triggering domestic taxation.

FAQ
Does territorial mean zero tax on foreign income?
In principle, yes for active foreign-source income. Passive or tainted income may still be caught by CFC or anti-deferral rules, and source rules can be narrower than they appear.
Is the US a territorial system?
Hybrid. Post-2017 the US exempts most foreign dividends through the DRD but layers GILTI, BEAT, and Subpart F on top, so it is not purely territorial.
Does Pillar Two affect territorial regimes?
Yes indirectly. Even territorial regimes must consider GloBE top-up tax when in-scope groups have low-taxed foreign profits.
