Is staying under 183 days always safe for tax?

No. A permanent home or family base can trigger tax residency well before the day count does, especially in France and Spain.

What is territorial taxation?

Only locally-sourced income is taxed. Foreign remote income is generally left alone, which is why countries like Panama and Costa Rica appear in nomad plans.

Do US citizens escape worldwide tax by leaving?

No. US citizenship-based taxation follows you worldwide regardless of where you live. The 1040 filing obligation does not end when you move.

No. It is a reference to know which questions to ask. Take any consequential move to a qualified adviser in the country involved.

The part nomads get wrong

The 183-day rule is the floor, not the whole story

Almost everyone has heard the line: stay under 183 daysand you are fine. It is a useful rule of thumb and it is also where people get burned. Day count is only one of several tests a country can use. A permanent home, your family’s location, where your economic life sits, even where your car is registered, any of these can make you tax-resident long before you hit 183 days. France and Spain in particular look at the whole picture, not just the calendar.

Worldwide vs territorial is the question that matters

Becoming tax-resident is only frightening if the country taxes worldwide income. Plenty do not. A territorial system taxes money earned inside the country and leaves your foreign remote income alone, which is exactly why places like Panama, Costa Rica, and Hong Kong keep showing up in nomad plans. The table above marks which is which. Read that column before you read the tax rate, because a high headline rate on territorial income you never earn locally is irrelevant to you.

Special regimes are the actual prize

Several countries run expat-friendly regimes that matter more than the standard rate. Portugal’s successor to NHR, Italy’s impatriate scheme, Cyprus non-dom, the Greek and Spanish inbound programmes: each can shelter foreign income or flatten the rate for a fixed number of years. They also come with conditions and clocks. The detail pages spell out what each one shelters and where it stops, which is usually the bit that decides whether a move is worth it.

The American exception

One passport ignores all of this. US citizens are taxed on worldwide income wherever they live, full stop. Leaving the country does not end the filing obligation; the Foreign Earned Income Exclusion and foreign tax credits soften it but the 1040 follows you. If that is your situation, read the United States entry above and budget for an accountant who handles expats, not a generic one.

None of this is tax advice. Residency rules are interpreted case by case and the consequences of getting them wrong are real. Use this to know which questions to ask, then take a consequential move to a qualified adviser in the country involved.
