The first truth
Americans still file with the US after moving abroad.
US citizens generally remain connected to the US tax system wherever they live. That means the European move should be planned with a US expat-tax professional before the residence route, property purchase and banking setup become real.
This does not automatically mean paying twice. It does mean the family should know which country can tax what, how treaty logic is expected to work, what reporting obligations appear and what timing should be avoided.
The local side
Europe adds a second tax system, not a replacement.
Each country decides tax residency differently. Days in country matter, but they are not the only factor. Home, family, center of life, employment, investment income, local registrations and treaty tie-breakers can all matter depending on the country. The dedicated guide is European tax residency for Americans.
That is why a move to France, Italy, Spain, Portugal, Greece or Monaco should not be framed as a visa question only. The residence route, property use and tax calendar sit together. Where a special regime is in play, the arithmetic pages frame the questions for counsel: Italy's flat tax, Spain's Beckham Law and France's IFI.
- France: powerful lifestyle and healthcare, but residence and estate planning need early coordination.
- Italy: attractive lifestyle and tax regimes for some new residents, but the timing has to be modeled.
- Spain: strong quality of life, with regional taxes and residency timing that need careful review.
- Portugal: a softer landing for many Americans, with tax rules that have changed and must be checked currently.
- Greece: residence and property routes can be attractive, but tax and remittance assumptions should be tested.
- Monaco: a narrow high-liquidity route where personal tax, housing, banking and French sequence must be coordinated.
The property trap
The house can create tax questions before the move is decided.
A property purchase can raise questions about ownership, rental income, local taxes, wealth reporting, inheritance and when the family becomes resident. A bank account opened for a deposit can also create US reporting duties.
The safest sequence is not romantic, but it works: tax review, residence route, bank readiness, FX plan, then property. That does not slow the dream down. It stops the dream from creating avoidable tax friction. The pre-move decision audit maps that sequence against your own facts in a few minutes.

Before you choose
Ask these questions before moving to Europe.
- Which country would tax us if we spent the number of days we actually want there?
- What happens if we buy before becoming resident?
- Will the US advisor, US CPA and local tax specialist be aligned before the purchase?
- Which bank will accept the file as US citizens?
- What reports do foreign accounts and assets create for the US side?
- What should happen before December 31 of the year we move?

US tax questions Americans ask before moving.
Do Americans still file US taxes after moving to Europe?
Yes. US citizens and resident aliens generally remain subject to US filing rules on worldwide income whether they live in the United States or abroad.
Does moving to Europe mean double taxation?
Not necessarily. Tax treaties, foreign tax credits and other rules often reduce or prevent double taxation, but the sequence of residence, income, property and bank accounts must be planned with qualified tax professionals.
When should Americans talk to a tax advisor before moving to Europe?
Before signing a property contract, moving funds, choosing a residence route or crossing a day-count threshold. Tax planning should happen before the family commits to the European file.
