Can One Adviser Coordinate My German and US Tax Returns?

Why can an American in Germany have obligations in both countries?

The United States generally taxes its citizens and resident aliens on worldwide income. Moving to Germany does not, by itself, switch that system off. Whether a particular US return is required still depends on filing status, income thresholds and other applicable rules. The IRS expressly explains that the basic filing rules normally continue to apply to Americans abroad.

Germany uses a different starting point. A person with a German residence or habitual abode will normally be subject to unlimited German income-tax liability, subject to treaty qualifications and particular exceptions. German residence can therefore bring foreign income within the German tax review even when it was paid into an American account.

The result is not simply two identical returns. Each system has its own definitions, deductions, forms and relief mechanisms. An item can be reported in both countries while a credit or treaty rule prevents some or all of the overlapping tax. Reporting and actually paying additional tax are separate questions.

What does coordinated preparation actually involve?

Good coordination begins with one factual record: residence dates, citizenship or Green Card status, work locations, income sources, account ownership and tax payments. Those facts should not change depending on which adviser is preparing the return. The German and US calculations can differ, but they should be based on the same documented transactions.

The team then identifies which person or entity prepares each return and which additional reports are included. Form 1040, a German Einkommensteuererklärung, an FBAR and Form 8938 are not interchangeable deliverables. An agreed filing package should name them rather than promise vaguely that all international tax is covered.

The most valuable part of coordination often happens before either return is finalised. The adviser compares income classifications, treaty positions and available relief, then checks whether a later German assessment or refund changes the US calculation. A German refund can affect the amount of foreign tax available for a US credit; it should not disappear into a separate file.

• One reconciled income schedule, supported by payroll, investment and business records.
• Separate calculations for German and US purposes, with explained differences.
• A documented decision on treaty provisions, credits, exclusions and reporting.
• Clear responsibility for submission, payment deadlines and later assessments.

Should I use Foreign Tax Credit or the Foreign Earned Income Exclusion?

A Foreign Tax Credit can reduce US tax for qualifying foreign income taxes, subject to the relevant limitations and income categories. The IRS lists four basic conditions: the tax must be imposed on you, paid or accrued, represent a legal and actual foreign liability, and be an income tax or qualifying substitute. The amount withheld is not always the amount ultimately creditable.

The Foreign Earned Income Exclusion, commonly called FEIE, is different. It can exclude qualifying foreign earned income if the foreign tax-home and residence or physical-presence conditions are met. The physical-presence test generally requires at least 330 full days in foreign countries within a consecutive twelve-month period. Merely having a German address is not enough.

FEIE is not a general exemption for everything an expatriate earns. Interest, dividends and pension income do not become foreign earned income simply because the owner lives abroad. The exclusion also does not itself remove US self-employment tax. Tax on income excluded under FEIE cannot also be used to claim a Foreign Tax Credit for that excluded income.

For a person paying substantial German income tax, a credit-based approach may be important, but it is not automatically the correct election for every year. Compare the actual income mix, tax timing, credit categories, prior elections and future plans. The decision should be made across both returns, not from a slogan that one method is always better.

Does the Germany-US tax treaty mean I only file once?

No. A double-taxation treaty allocates taxing rights and provides relief rules; it is not a replacement for domestic filing obligations. The US-Germany convention also contains a saving clause that generally preserves US taxation of US citizens, with specified exceptions. It is therefore unsafe to say that German residence makes an American entirely exempt from the US system.

Treaty analysis is income-specific. Salary, self-employment, rental income, dividends, retirement arrangements and social-security payments are not all governed by the same article. Citizenship, residence, the source of the payment and the nature of the benefit can affect the result.

For retirement income, for example, the team needs to distinguish Social Security from a private pension, IRA or employer plan. An account label alone does not determine the German tax category, the treaty allocation or any US reporting. Both the convention and relevant protocols need to be considered before adopting a position.

Are FBAR and Form 8938 included in Form 1040?

An FBAR is a separate FinCEN report, not a schedule that automatically appears when Form 1040 is filed. A US person with a financial interest in, or signature authority over, foreign financial accounts generally needs to review FBAR when their aggregate value exceeds US$10,000 at any time during the calendar year. The threshold is across accounts, not a separate US$10,000 allowance for each account.

Form 8938 concerns specified foreign financial assets and has its own thresholds, including different rules depending on filing status and whether the taxpayer lives abroad. It can be required in addition to an FBAR. An account that earns no interest may still matter for an information report.

German current accounts, savings accounts and investments should therefore be reviewed separately from the income-tax computation. The engagement should expressly state whether the team is assessing and preparing the relevant information reports. Neither a low final tax bill nor the FEIE election proves that account reporting can be omitted.

What does a coordinated review look like in practice?

Consider an illustrative US citizen working in Germany, receiving German salary, holding US investments and maintaining German bank accounts. This is a fictional example, not a client case. The German review establishes residence, employment treatment and the reporting of overseas investment income. The US review includes worldwide income and examines the appropriate credit or exclusion treatment.

The German accounts are also checked against FBAR and Form 8938 rules. Any US state filing question is reviewed separately rather than assumed to disappear when federal relief applies. If a German assessment later refunds tax, the team considers whether that changes a previously claimed US Foreign Tax Credit.

The useful outcome is an explained, reconciled filing position with clear responsibilities. It is not a promise that both countries will arrive at identical taxable income or that every client will owe no additional tax.

What should I provide before the returns are prepared?

Provide prior German and US returns and assessments, the dates and places you lived and worked, citizenship or Green Card information, payroll statements and records of tax paid. Include business income, pensions, investment statements, account ownership and maximum foreign account balances where relevant.

Missing years need a separate procedural assessment. Do not assume that a particular late-filing or streamlined procedure is available without checking its eligibility conditions. Likewise, an extension of time to file is not automatically an extension of time to pay.

Frequently asked questions

Can the same team prepare my German return and Form 1040?

Yes, where both filings are included in the accepted engagement. The team should identify the responsible preparer for each jurisdiction and reconcile the facts and tax-relief positions across the returns.

Does paying German tax remove my US filing obligation?

Not necessarily. German tax may support a qualifying Foreign Tax Credit, but US filing rules and information-report requirements must still be assessed separately.

Does FEIE cover my dividends or pension?

No. FEIE concerns qualifying foreign earned income. Dividends, interest and pension or annuity payments are not foreign earned income merely because you live outside the United States.

Is an FBAR required only if each account exceeds US$10,000?

No. The general threshold concerns aggregate foreign account value exceeding US$10,000 at any time during the calendar year, subject to the applicable ownership and reporting rules.

Can a German tax refund affect my US return?

Yes. A refund can change the foreign tax available for credit and may require a US adjustment. Tell the team when an assessment or refund changes the original tax figure.
