U.S. Tax Filing for Americans in Amsterdam

Amsterdam draws a large American community into tech, finance, scale-ups and the creative sector, many arriving on the well-known 30% ruling. The Netherlands and the U.S. have a tax treaty, but the Dutch system works differently in ways that matter for a U.S. return — most notably the box 3 wealth tax, which taxes assets rather than the income they produce.

Typical situations we see in Amsterdam

• The 30% ruling, which reduces Dutch tax on qualifying expat salary — favourable locally, but the U.S. still generally taxes worldwide income and the interaction with the Foreign Tax Credit is worth getting right.
• Dutch box 3 wealth tax, which taxes the value of savings and investments rather than realised income — a deemed-return system that does not always line up neatly with U.S. income-based taxation or the Foreign Tax Credit.
• Dutch mutual funds, ETFs and investment accounts held through a local broker that may be treated as PFICs (Form 8621).
• Finance and tech professionals with RSUs, options and bonuses to reconcile across Dutch and U.S. rules.
• Multiple Dutch bank and investment accounts that together cross the FBAR and FATCA (Form 8938) thresholds.

Box 3 and the Foreign Tax Credit

Because box 3 taxes a deemed return on your assets rather than actual income, how it maps to the U.S. Foreign Tax Credit can be nuanced and may not offset U.S. tax the way an income tax would. It is generally worth reviewing how your box 3 liability interacts with your U.S. return rather than assuming it cancels out. Atamatax provides preparation support; this is not individualized advice.
