US tax filing abroad,
adapted to where you live.
The US federal filing system follows the taxpayer, not the address. A US citizen in Copenhagen, Milan or Berlin files on worldwide income the same way a citizen in Chicago does — and usually owes little after the Foreign Tax Credit.
What changes country to country is everything underneath: the accounts you hold, the investment products your bank actually sells you, and how your pension is built. Atamatax layers jurisdiction-specific logic on top of one US filing engine.
Country desks
Local accounts, local products, local pensions — mapped to US forms.
A country desk covers the whole corridor: which local accounts are reportable, which local investment products create Form 8621, how the pension system is analysed, and the catch-up route if you are behind.

Treaty desks
Bilateral treaty workflows, article by article.
A treaty desk is narrower than a country desk on purpose: it covers the convention — dividends, interest, pensions, capital gains, double-taxation relief, and when Form 8833 is genuinely relevant. These countries do not have a full country desk yet.

Guides
Country guides without a desk — yet.
Real country-specific writing, but no article-level treaty workflow and no full desk. Listed separately so the distinction is visible rather than implied.
What these tiers mean
Not on this page? You can still file.
US federal filing is a function of citizenship, not of the country you live in. Atamatax produces the same draft package for a US person in Lisbon or Seoul as for one in Zurich — Form 1040, the Foreign Tax Credit on Form 1116, FBAR values, Form 8938 thresholds and a Form 8621 for each PFIC.
What a country desk adds is local knowledge: knowing that an Aktiesparekonto is a look-through, that a Pillar 3a is a PFIC trap, that Quadro RW is not the FBAR. What a treaty desk adds is the article map the workflow cites. Where we have neither, the engine still runs — we just do not pretend to jurisdiction-specific expertise we have not written down.
Atamatax is tax-preparation software, not a CPA firm, enrolled agent or tax attorney. Nothing here is individualised tax advice.
