Czech personal rates are 15% and 23%, which is the important number: at those rates the foreign tax credit frequently fails to cover the US liability, so the Foreign Earned Income Exclusion is often the better election — the opposite of the Western European and Nordic pattern. Image: A treaty and a totalization agreement both in place, with the exclusion marked as the route low Czech rates usually favour.

Rivas, EA Enrolled Agent · 6 minutes to read ## Low rates reverse the usual answer In a country taxing at 45%, the credit almost always covers the US liability and the exclusion is the worse choice. Czechia taxes at 15% and 23%, and that changes the conclusion: the credit can come in below the US tax on the same income, leaving a bill the exclusion would have removed. It is still a computation rather than a rule. What is different here is which way the presumption points before the computation is run. ## Czech contributions are not creditable Social security and health insurance contributions are not income taxes and do not belong on Form 1116. The totalization agreement is what addresses that side, with a certificate of coverage — which means the creditable Czech tax is only the income tax itself, and the gap between total deductions and creditable tax is wider here than people expect. ## Prague rent supports a real housing exclusion Where the exclusion route is taken, the foreign housing exclusion sits on top of it: qualified housing costs above 16% of the exclusion and capped at 30%, which for tax year 2025 means a base of $20,800 and a cap of $39,000. Prague rents are high enough for that to matter, and it needs the lease to compute rather than an estimate. ## One treaty for Czechia, another for Slovakia The treaty dates from 1993 and applies to Czechia as successor to Czechoslovakia. Slovakia has its own separate treaty. Anyone who has moved between the two — common enough — should not assume a single document covers both periods. ## A worked example, tax year 2025 A single American employed in Prague on $200,000, with Czech income tax of about $36,000. Czech figures are illustrative; the US figures are computed. | Salary | $200,000 | | --- | --- | | Czech income tax paid | $36,000 | | US taxable income after the standard deduction | $184,250 | | US income tax before the credit | $37,067 | | Credit route — US income tax after the credit | $1,067 | | Exclusion route — excluded under §911 | $130,000 | | Exclusion route — plus the housing exclusion | Available on the lease | The credit leaves $1,067 standing because Czech tax came in just below the US figure — a small number at this salary, and a growing one as income rises. The exclusion removes $130,000 from the base before any housing exclusion is claimed, which usually produces the better result here. Revoking the exclusion binds for five years, so the choice is made deliberately. Sources: IRC §901, §904 and §911; IRS Form 2555 instructions; Rev. Proc. 2025-32.

Usually the exclusion, because Czech rates of 15% and 23% often leave the credit short of the US liability. It is computed on your figures — but the presumption here runs the opposite way from Western Europe. ### Do I pay US self-employment tax in Czechia? Not usually. The totalization agreement is in force, so with a certificate of coverage self-employment is subject to one country's system rather than both. ### Are Czech social security and health contributions creditable? No. They are not income taxes, so they do not go on Form 1116. Only the Czech income tax itself supports a credit, which is why the creditable figure is smaller than the total deducted. ### Does the Czech treaty cover Slovakia too? No. The 1993 treaty applies to Czechia as successor to Czechoslovakia, and Slovakia has its own separate treaty. Anyone who has lived in both should not assume one document covers both periods. ### I have not filed for several years while in Czechia. What now? If the failure was non-willful — which describes most people in this position — the Streamlined Foreign Offshore Procedures waive the failure-to-file, failure-to-pay and FBAR penalties: three years of returns, six years of FBARs, and Form 14653. ## Filing from Prague? Fifteen minutes and your own figures settle which election actually costs less — the presumption here runs the other way.
