What is the most tax-friendly country for expats?

There is no single winner — it depends on your income type. For a salary, a no-income-tax state like the UAE or Monaco is hard to beat. For a foreign pension, Greece's 7% flat tax, Italy's southern-towns 7% regime, or a territorial country like Panama can be ideal. For wealthy investors, Italy's lump-sum flat tax or Switzerland's forfait suit best.

Are low-tax countries actually cheaper to live in?

Not necessarily. Many still levy VAT, property and social-security charges, and residency often requires a property purchase or large deposit. Monaco and Switzerland are expensive despite low income tax. Weigh total cost of living, healthcare and visa rules, not just the headline rate.

Do US citizens benefit from moving to a low-tax country?

Partly. US citizens are taxed on worldwide income wherever they live. A low-tax country reduces local tax but leaves less foreign tax to credit against the US bill, and many lack a totalization agreement, so US self-employment/social-security exposure can remain. The FEIE still helps on earned income.

Best low-tax countries for expats in 2026

Choosing where to move on tax grounds means understanding how a country taxes a foreigner who relocates — not just its headline rate. Three structural features decide your bill: when you become a tax resident, whether the country taxes your worldwide or only your local income, and whether a special regime exists. This guide ranks the friendliest destinations for 2026 and explains the catch in each.

The three families of low-tax destinations

Family	How it works	Best for	Examples
No income tax	No personal income tax at all	Salaries, pensions, gains	UAE, Qatar, Monaco, Bahamas, Cayman, Bermuda
Territorial / remittance	Taxes only local-source (or remitted) income	Remote workers, retirees with foreign income	Panama, Costa Rica, Georgia, Malaysia, Singapore, Hong Kong, Malta
Special regime	Worldwide tax, but a carve-out for new arrivals	Wealthy movers, pensioners, skilled workers	Italy, Greece, Spain, Portugal, Cyprus, UK

All figures below are headline rules for 2026, compiled from PwC Worldwide Tax Summaries and official authorities. They are general information, not tax advice.

No-income-tax states

The cleanest option: if there is no personal income tax, a resident pays nothing locally on salary, a foreign pension or capital gains. The Gulf states (UAE, Qatar, Saudi Arabia, Bahrain, Kuwait) and a handful of independent jurisdictions (Monaco, the Bahamas, Cayman Islands, Bermuda, BVI) levy 0% income tax. The catches: VAT (5% in the UAE, 15% in Saudi Arabia), a payroll tax on local employment in Bermuda and the BVI, and residency that usually needs a property purchase or deposit. See the full no-income-tax list.

Territorial-tax countries

A territorial country taxes only income sourced inside its borders and ignores income earned abroad. Panama and Costa Rica are the classic retiree picks; Georgia is a nomad favourite (with a 1% small-business regime); Malaysia, Singapore and Hong Kong exempt foreign-source income for individuals. The nuance: work physically performed while you sit in the country can be treated as local-source even if the client pays from abroad.

Special regimes worth knowing

Several high-tax countries layer a generous carve-out on top:

Italy — a lump-sum flat tax on all foreign income (EUR 200k for 2025 opt-ins, EUR 300k from 1 January 2026) for up to 15 years, plus a 7% regime for pensioners in small southern towns.
Greece — a flat 7% on all foreign income for retirees for 15 years, or a EUR 100k non-dom lump sum.
Spain — the Beckham Law: a flat 24% on Spanish employment income to EUR 600k, with foreign investment income exempt, for about six years.
Portugal — IFICI, the NHR successor: a 20% rate on qualifying Portuguese income and most foreign income exempt — but foreign pensions are taxed normally.
Cyprus — non-dom status: foreign dividends and interest effectively untaxed for 17 years.

The bottom line

Run your own income through three questions: how easily do I become resident, is my foreign income in scope, and is there a regime I qualify for? Then check the day counter and the relevant country profile — and confirm with a cross-border adviser before you move.
