Frequently asked questions

Is Portugal or Thailand better for tax?

On income tax alone, Thailand has the lower effective rate at a $100,000 income (23.3% vs 35.6%). But the right answer depends on your income level, which special regime you qualify for, social security, and treaty relief — see the full comparison below.

Which has the lower tax-residency threshold, Portugal or Thailand?

Portugal treats you as tax resident after 183 days, and Thailand after 180 days. But ties like a home, family or economic centre can trigger residency on fewer days — never rely on a day count alone.
