Americans abroad: tax obligations follow citizenship, not residence

Washington taxes its citizens' worldwide income even if they never set foot in the country

The United States is one of the few countries in the world that taxes its citizens on worldwide income, no matter where they live. It does not matter that all income comes from a foreign jurisdiction or that the taxpayer has not set foot on American soil in years: the annual filing requirement still applies. Those who fail to comply face penalties, accumulated interest and legal ramifications. The only way to escape that bond, according to the framing that opens the discussion, is to renounce citizenship.

The case has a famous precedent that is being recalled these days: Tina Turner applied for Swiss nationality when she was already living in Switzerland. The question hanging in the air is whether it was a decision of tax convenience or simply of lifestyle. The short answer: both can be true.

What taxes does a non-resident with a US passport pay?

The obligation makes no distinction between residents and non-residents when nationality is involved. The US tax system is based on citizenship, not domicile, unlike most European regimes, which tax based on effective residence. That is why a citizen who has spent a decade on another continent still has to file an annual return.

Non-compliance is no trivial matter. Penalties pile up, interest accrues and the legal ramifications can reach dimensions that surprise those who associate taxation with residence. Some argue that the IRS neither forgives nor forgets, and its fruta for being relentless is no talk-show exaggeration.

Renouncing the passport: the only way out

Renouncing citizenship appears as the only mechanism to break the tax bond. It is not a minor or cheap procedure, and it has consequences that go beyond the accounting. But it is the route the system provides for anyone who wants to stop filing returns from abroad.

The comparison with Spain comes up immediately. Spain has the modelo 720 (a reporting form for foreign assets), but it applies to tax residents in Spain, not to those living abroad. The difference in approach is substantial: the Spanish regime taxes by residence, the American one by nationality. That asymmetry explains why some taxpayers with dual nationality are weighing decisions they would never have imagined years ago.

The future of citizenship-based taxation

The underlying debate is whether this model will survive the pressure of globalization. Some predict that other countries will eventually copy the scheme to prop up their public finances. Others believe that tax competition between jurisdictions will make it unsustainable to tax people who neither live nor consume services in the territory.

For now, reality is stubborn: the American passport comes with an annual bill. And giving it up is not a decision to be taken lightly. The most plausible prediction is that the number of renunciations will keep growing among those with significant assets outside the country, though the pace will depend on factors that have not yet fully materialized.
