Why US Citizens Living in Switzerland Should Hire a US Tax Preparer
US citizens living in Switzerland face overlapping US and Swiss filing and reporting obligations under citizenship-based taxation, so an enrolled agent with expat experience is usually the practical choice to handle both sides.

For the U.S. filing side of this topic, use the IRS International Taxpayers guidance alongside the country-specific material here. U.S. citizens abroad remain subject to U.S. tax rules, but return-filing obligations depend on income, filing status, thresholds, and other facts. The Foreign Earned Income Exclusion and Foreign Tax Credit may reduce double taxation when their requirements are met; neither automatically removes all filing or tax.
The complexity comes from Swiss pillar pensions, the lump-sum taxation regime, and banking secrecy.
The Switzerland-US Tax Relationship
The FEIE excludes up to $130,000 of foreign-earned income from US tax. The FTC credits foreign taxes paid against US tax on the same income. Each election has different consequences. In Switzerland, the right choice depends on the local tax rate, the type of income, and whether you're planning to stay long-term.
FBAR applies if your Switzerland bank accounts exceed $10,000 in aggregate. FATCA applies through the intergovernmental agreement between the US and Switzerland. Form 8938 may apply for higher thresholds.
Why the Returns Aren't Simple
Most domestic preparers don't understand Switzerland financial products. A Switzerland pension is not a 401(k). A Switzerland ISA is not a Roth. A Switzerland investment account may hold PFICs that require Form 8621 reporting. The interaction between the two tax systems creates complexity that generalist preparers can't handle.
An EA who understands Switzerland tax structures. the local retirement system, the investment vehicles, the treaty provisions. is worth their fee many times over.
The EA Advantage
The EA credential is federal, and EAs generally have unlimited IRS representation rights. The three SEE parts cost $951 for the 2026 cycle. Cross-border work also requires country-specific competence; the EA is not the only credential used in this field.
No reliable source reviewed here measures the number of Switzerland-focused EAs or guarantees a client market. Population counts do not equal paying clients.
