Yes, for residents, except French citizens under a bilateral treaty. No personal income tax, no capital gains tax, no wealth tax, no direct-line inheritance tax. This system dates to 1869 when Monte Carlo casino revenues were large enough to abolish taxes. But note: residency in Monaco does not automatically end your tax obligations in your home country — that depends on whether you legally transfer your tax residence under your home country's law.

Three core requirements: a place to live in Monaco (purchase or rent, appropriate size for household members); proof of sufficient financial means — typically opening an account at a Monaco bank and depositing a substantial sum with a bank confirmation letter; and a clean criminal record. Citizens of countries outside the Schengen area, including Vietnam, must first obtain a long-stay visa from France, as Monaco has no separate consular office to issue visas.

Yes. Typically you must spend at least three months per year with an initial permit, and authorities conduct real residency checks. This is not a paper permit like some other programs.

Virtually no. Monaco citizenship requires many years of continuous residency, is at the sole discretion of the Sovereign Prince, and mandates renouncing your original citizenship. In practice, it is very rarely granted to foreigners without family ties to Monaco — only about one-quarter of Monaco's population holds Monaco citizenship.

The highest in the world, especially real estate — price per square meter ranks among the highest globally due to extremely limited supply on 2.08 km². This dominates any budget. You can shop more cheaply in neighboring French towns.

Monaco is not an EU member state, but uses the Euro and is effectively within the Schengen travel area through its open border with France.

Public schools follow the French curriculum, are high quality and free for residents, with small class sizes. There are international schools offering English-language programs. Healthcare is very high quality with the Princess Grace Hospital Center; Monaco is also close to Nice and Italy, so access to French and Italian healthcare systems is convenient.

Monaco has no airport. Nice Côte d'Azur International Airport is about 30 km away — 30–45 minutes by car or about 7 minutes by helicopter with regular services. From Vietnam, there are no direct flights; connections typically go through Paris, Dubai, Doha, or Istanbul, totaling 16–20 hours.
