US Expat Taxes in Germany: The Complete 2026 Guide

If you are a US citizen or green card holder living in Germany, you face tax obligations in both countries. The United States taxes its citizens on worldwide income regardless of residence, while Germany taxes its residents on worldwide income under a progressive system with rates reaching up to approximately 45%. On top of that, Germany levies a solidarity surcharge (Solidaritätszuschlag, commonly called "Soli") and, for registered church members, a church tax (Kirchensteuer). Without the right structure, double taxation is a real risk.

This guide walks through everything a US expat in Germany needs to know: the US-Germany income tax treaty, FBAR and FATCA reporting for German accounts, choosing between the Foreign Tax Credit and the Foreign Earned Income Exclusion, the PFIC trap with German investment funds, Social Security coordination under the Totalization Agreement, key deadlines, and the most common mistakes expats make.

The US-Germany Tax Treaty (1989)

The Convention Between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation, signed in 1989 and updated by subsequent protocols, is the foundation of cross-border tax planning for US expats in Germany. It allocates taxing rights between the two countries for different income categories and provides mechanisms to eliminate double taxation. For a broader overview of how treaties work, see our double taxation treaties guide.

Employment Income (Article 15)

Salary and wages are generally taxed in the country where the work is physically performed. If you live and work in Germany, Germany has the primary taxing right on your employment income. Because the US also taxes you as a citizen, you report the same income on your US return and claim a Foreign Tax Credit on Form 1116 for German income taxes paid. Given that German combined rates typically exceed US rates, the credit usually eliminates your US tax liability on employment income entirely.

Pensions (Article 18)

Under the treaty, private pensions and annuities are generally taxable only in the country of residence. US Social Security benefits paid to a German resident are taxable only in Germany under the treaty — meaning the US does not tax them, provided you claim treaty benefits on Form 8833. Conversely, German statutory pension payments (gesetzliche Rente) received by a US resident are generally taxable only in the US. Because pension treaty treatment can be complex — particularly for hybrid private arrangements — consult a cross-border tax professional for your specific situation.

Dividends and Interest

Dividends paid from US companies to a German resident are subject to a reduced withholding rate under the treaty. Interest income is generally taxable only in the country of residence. If you hold US brokerage accounts and live in Germany, file a W-8BEN with your US broker to claim reduced treaty withholding rates, and report the income in both countries, crediting US withholding tax against your German liability.

Capital Gains

Gains from the sale of personal property (stocks, bonds) are generally taxable only in the country of residence under the treaty. If you live in Germany and sell US equities, Germany generally has the primary taxing right. Real estate gains are taxed in the country where the property is located: a gain on a US property is taxed in the US; a gain on a German property is taxed in Germany.

FBAR for German Accounts

If the aggregate maximum balance of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR (FinCEN Form 114). This threshold is calculated by adding together the highest balance reached in each account during the year, converted to USD at the Treasury Department's year-end exchange rate. For most US expats in Germany, this threshold is easily exceeded.

The following German account types must be included in the aggregate calculation:

• Girokonto (checking account) at any German bank — Deutsche Bank, Commerzbank, DKB, ING, N26, Sparkasse, and similar institutions.
• Tagesgeldkonto (instant-access savings) and Festgeldkonto (term deposit) — both are reportable foreign financial accounts.
• Depot (brokerage/securities account) — all holdings are valued and included in the aggregate. The underlying funds may also be PFICs (see below).
• Riester-Rente and Rürup-Rente pension contracts — these are reportable. Their US tax treatment is uncertain and complex (see the pensions section below).
• Bausparvertrag (building-savings contract, offered by Bausparkassen such as Schwäbisch Hall or Wüstenrot) — a hybrid savings and future-loan instrument that is a reportable foreign financial account.

The FBAR is filed electronically through the BSA E-Filing System, not with your tax return. ExpatFolio tracks your German account balances across all linked accounts and alerts you when you approach the $10,000 reporting threshold.

FATCA Form 8938: Specified Foreign Financial Assets

In addition to the FBAR, you may need to file FATCA Form 8938 with your federal tax return. The thresholds for expats living abroad are higher than for domestic filers:

• Single filers living abroad: file if foreign financial assets exceed $200,000 on the last day of the tax year or $300,000 at any point during the year.
• Married filing jointly living abroad: thresholds are $400,000 on the last day of the year or $600,000 at any point.

Form 8938 covers a broader range of assets than the FBAR. In addition to bank accounts, you must report foreign securities, interests in foreign entities, and financial instruments issued by foreign persons. For Germany, this includes your Depot holdings, Riester-Rente and Rürup-Rente contracts, and any shares in German companies (GmbH interests, for example). You may need to file both the FBAR and Form 8938 for the same accounts — they are separate requirements with different procedures, thresholds, and penalties.

Foreign Tax Credit vs. Foreign Earned Income Exclusion

US expats have two primary tools to avoid double taxation: the Foreign Tax Credit (FTC) claimed on Form 1116 and the Foreign Earned Income Exclusion (FEIE) claimed on Form 2555. For most Americans living in Germany, the FTC is the better choice — often by a significant margin. See our detailed FEIE vs. FTC comparison guide for a full analysis.

Here is the key reason: Germany's combined marginal rates typically exceed US rates. German income tax alone reaches up to approximately 45% for high earners. Add the solidarity surcharge (see below) and, where applicable, church tax, and your effective German tax burden can comfortably exceed your US liability on the same income. When that happens, the FTC eliminates your US tax entirely and generates excess foreign tax credits that can be carried forward for up to 10 years.

The FEIE allows you to exclude up to $132,900 (2026 figure) of foreign earned income from US taxation. However, in a high-tax country like Germany it often leaves money on the table: by reducing your US taxable income, it can push remaining income into lower brackets and reduce the value of German tax credits you could otherwise use. The FEIE also provides no relief for investment income, rental income, or self-employment income above the exclusion ceiling.

One important rule: you cannot apply the FTC and the FEIE to the same income. Switching between them requires careful planning and triggers a 5-year lock-out period for the FEIE. Get professional advice before choosing or changing your approach.

German Tax Extras: Solidarity Surcharge and Church Tax

Two charges sit on top of German income tax that US expats need to understand for their US return.

Solidarity Surcharge (Solidaritätszuschlag)

The solidarity surcharge — historically 5.5% of assessed income tax — was largely phased out for most taxpayers starting in 2021, but it continues to apply to higher earners above certain thresholds. Where it applies, it is levied as a percentage of your German income tax bill, not of your gross income. For US Foreign Tax Credit purposes, the solidarity surcharge is generally treated together with German income tax and is considered a creditable foreign income tax, since it is computed as a function of the income tax base.

Church Tax (Kirchensteuer)

If you are registered as a member of a recognized church in Germany, church tax of approximately 8–9% of your income tax liability (the rate varies by federal state) is withheld automatically. Whether church tax qualifies as a creditable foreign income tax on your US return is a genuinely contested question among cross-border tax practitioners. Some practitioners claim it as a creditable foreign tax alongside the income tax; others treat it as a non-creditable levy. Do not assume creditability without professional advice — the IRS has not issued definitive guidance on this point, and taking an unsupported position could attract scrutiny.

The PFIC Trap: German Investment Funds Are Toxic for US Taxpayers

This is one of the most costly pitfalls for US expats in Germany. A Passive Foreign Investment Company (PFIC) is any non-US fund where 75% or more of gross income is passive, or 50% or more of assets produce passive income. In practice, virtually all German collective investment vehicles meet this definition:

• Investmentfonds — the general category of German investment funds, whether equity, bond, or mixed.
• Any fund held inside a Riester-Rente or other fund-based retirement wrapper (fondsgebundene Riester).
• European UCITS ETFsdomiciled in Germany, Luxembourg, or Ireland — even if they track the S&P 500, their non-US domicile makes them PFICs.
• Any fund held in a German Depot account that is not a US-registered investment company.

The default PFIC tax regime under Section 1291 is punitive. Gains and excess distributions are spread over your entire holding period, taxed at the highest ordinary income rate for each year, and subject to an interest charge on top. Effective combined tax rates on PFIC gains can reach well above 50%. The alternative QEF (Qualified Electing Fund) and mark-to-market elections require timely annual reporting on Form 8621 for every PFIC you own — one form per fund, per year.

The simplest solution: do not buy German or European funds. Hold US-domiciled ETFs (from providers such as Vanguard, iShares US, or Schwab) in a US brokerage account. These are not PFICs and receive favorable US long-term capital gains treatment. ExpatFolio flags holdings that may be classified as PFICs so you can act before they become a tax problem.

Riester-Rente and Rürup-Rente: A Cross-Border Problem

Riester-Rente and Rürup-Rente (also called Basis-Rente) are German state-subsidized retirement savings vehicles that provide significant German tax advantages. However, their US tax treatment is genuinely uncertain and complex.

Both products may hold German Investmentfonds as their underlying investment, raising the PFIC issues described above. Additionally, there are open questions about whether these contracts could be treated as foreign trusts by the IRS (potentially triggering Form 3520 and 3520-A reporting obligations) and how the treaty's pension articles interact with these products. German tax law treats them as pensions; US tax law may not.

Do not assume that the German tax benefit transfers to your US return. If you hold a Riester or Rürup contract, work with a cross-border tax professional who understands both German pension law and IRS treatment of foreign retirement arrangements before making contributions or withdrawals.

Social Security: The US-Germany Totalization Agreement

The US-Germany Totalization Agreement, in force since 1979, prevents you from paying Social Security taxes to both countries at the same time. The general rule: you contribute to the system of the country where you work.

• If you are employed by a German company in Germany, you pay German social insurance contributions (Sozialversicherungsbeiträge) and are exempt from US Social Security (FICA) taxes on that employment income.
• If you are temporarily seconded to Germany by a US employer (for up to 5 years), you can remain in the US Social Security system by obtaining a Certificate of Coverage from the SSA.
• If you are self-employed in Germany, you generally pay into the German system and are exempt from US self-employment tax under the agreement.

The agreement also allows you to combine work credits from both countries to qualify for benefits. For example, if you worked 8 years in the US and 8 years in Germany, you can combine those periods to meet the US minimum threshold for Social Security retirement benefits. Under the treaty, US Social Security benefits paid to a German resident are generally taxable only in Germany.

Key Deadlines

• April 15: Standard US federal tax filing and payment deadline. If you owe tax, payment is due by this date regardless of any extension you file for the return itself. Interest accrues from April 15 on any unpaid balance.
• June 15: Automatic 2-month extension for US citizens and resident aliens living abroad. No form is required, but you must attach a statement to your return explaining you qualify. Interest on any balance due still accrues from April 15.
• October 15: Extended deadline available to all filers who submit Form 4868. Most US expats in Germany target this deadline to give their German tax figures time to be finalized before completing the US Foreign Tax Credit calculation.
• April 15 / October 15 (FBAR): The FBAR deadline mirrors the US tax deadline — April 15 with an automatic extension to October 15. No separate extension form is needed.
• July–August (German Einkommensteuererklärung): German residents who are required to file a German income tax return (Einkommensteuererklärung) face deadlines that vary by year and whether a tax advisor is involved. File your German return first so that the final German tax assessment figures are available for your US Foreign Tax Credit calculation.

Common Mistakes US Expats Make in Germany

• Not filing a US return at all: Living in Germany does not exempt you from US filing obligations. US citizens and green card holders must file if income exceeds the standard thresholds, wherever they live.
• Forgetting the FBAR: A standard Girokonto plus a Tagesgeldkonto and a small Depot can easily push aggregate balances over $10,000. Non-willful failure-to-file penalties can reach $10,000 per violation.
• Buying German investment funds: Opening a Depot and purchasing Investmentfonds or UCITS ETFs seems natural when banking in Germany, but the PFIC consequences can be severe. Hold US-domiciled ETFs in a US brokerage account instead.
• Using the FEIE instead of the FTC in a high-tax environment: Germany's combined tax burden typically exceeds US rates. The Foreign Tax Credit usually produces a much better outcome and can generate carry-forward credits.
• Ignoring Riester and Rürup reporting complexity: These contracts may raise PFIC, foreign-trust, and treaty-treatment questions simultaneously. Do not assume your German tax advantage carries through to your US return without professional guidance.
• Assuming church tax is straightforwardly creditable: The creditability of Kirchensteuer against US tax is contested. Get qualified advice rather than treating it as automatically creditable.
• Not coordinating German and US filing timing: Your US Foreign Tax Credit is based on German taxes actually assessed, not estimated. Filing your German return first and using final assessment figures avoids an amended US return later.
• Missing the Bausparvertrag on FBAR: This contract type is less obviously a "bank account," but it is a foreign financial account held at a financial institution and must be included in the aggregate threshold calculation.

Navigating the US-Germany tax landscape requires understanding two sophisticated tax systems simultaneously. Keep your investments in US-domiciled funds to sidestep the PFIC trap, track all German accounts carefully for FBAR and FATCA compliance, and use the Foreign Tax Credit to offset double taxation. For a comparison with life in France — another high-tax treaty country — see our US expat taxes in France guide. Work with a cross-border tax professional who understands both the German system and IRS treatment of German financial products, particularly for Riester, Rürup, and church tax questions where US treatment remains genuinely uncertain.
