Andorra vs Monaco: expat tax
For a foreigner who relocates, Monaco is generally the lighter-tax option of the two. Andorra taxes residents on a worldwide basis with a top rate of 10% and the Passive (non-lucrative) residency regime; Monaco uses a territorial basis at 0% (no personal income tax) with no special regime. This weighs the tax treatment of foreign income only — residency rules, treaties, visas and cost of living all change the real picture, and this is not tax advice.

Verdict
Judged on how each country taxes a mover's income, Monaco is the friendlier choice — it largely leaves foreign income alone, while Andorra reaches worldwide income. But that is a blunt verdict: it ignores how easily you trigger residency, the income bands those top rates apply to, social-security contributions, treaty relief and your own circumstances. Read each full profile (Andorra and Monaco) and check residency with the day counter before drawing conclusions.
Frequently asked questions
Is Andorra or Monaco better for expats on tax?
On the tax treatment of a foreigner who moves in, Monaco is generally the friendlier of the two: it taxes residents on a territorial basis at a top rate of 0% (no personal income tax), versus a worldwide basis at 10% in Andorra. This weighs tax only — visas, cost of living and healthcare differ too. Not tax advice.
Does Andorra or Monaco tax foreign pensions more lightly?
Andorra: Included in worldwide income, taxed on the IRPF scale (0% up to EUR 24,000, 5% to 40,000, 10% above EUR 40,000). Monaco: Not taxed in Monaco (no personal income tax); a foreign pension may still be taxed at source by the paying country. A double-tax treaty can move the taxing right between the source country and your new home, so a retiree should map their specific pensions against the relevant treaty.
When do you become a tax resident in Andorra vs Monaco?
Andorra: 183 days in a calendar year, or Andorra is the centre of your economic/vital interests. Monaco: Hold a residence card and spend 183+ days/year in Monaco, or make it your main home. Day counts are only the headline — a home or family ties can make you resident sooner in either. Track your days carefully and confirm with a local adviser.
Should I move from Andorra to Monaco for tax reasons?
Tax is only a starting point. Your real liability turns on tax residency, where income arises, exit taxes in your old country, the relevant treaty and — for US citizens — worldwide/citizenship-based taxation.
