When you need a cross-border tax advisor (and when you don't)
If you are a US citizen or green-card holder with no German income, no German bank or brokerage accounts, no German real estate, and no German pension claims, a regular US CPA is fine. The moment any of those exist, you have a cross-border situation. The clearest triggers are: any German bank or brokerage account exceeding $10,000 in aggregate at any point in the year (FBAR / FinCEN 114 reporting), any specified foreign financial assets above the IRS Form 8938 thresholds, German rental income (must be reported on Anlage V in Germany and Schedule E in the US, with foreign tax credit reconciliation), German pension contributions or distributions (Riester-Rente, Rürup-Rente, betriebliche Altersversorgung — each treated differently by the US-Germany treaty), and any inheritance or gift from a German person above the federal estate-tax exclusion threshold.
What "dual-qualified" actually means
Tax advisors marketing themselves as cross-border experts fall into three tiers. The strongest are dual-licensed: licensed as a US CPA (or Enrolled Agent) AND as a deutscher Steuerberater registered with a Steuerberaterkammer. They can sign filings on both sides and have professional liability coverage in both jurisdictions. The second tier is single-licensed but specialized: a US CPA who has built deep practice expertise in German cross-border issues and partners with a German Steuerberater for the German filings. Many of the best advisors fall here. The weakest tier is generalist CPAs who claim cross-border capability based on having a few German clients — they will get you through standard FBARs but lack the depth for treaty disputes, exit-tax planning, or pension structuring. Ask directly: "Are you licensed as a Steuerberater in Germany?" If no, "Do you partner with a Steuerberater for German filings?" If still no, keep looking.
Specific filings a US-Germany advisor must handle in their sleep
On the US side: Form 1040 with Schedule B for foreign accounts, Form 8938 (FATCA — Statement of Specified Foreign Financial Assets), FBAR / FinCEN 114 (the standalone foreign account report — different threshold than 8938), Form 8833 (treaty-based return position disclosures), Form 1116 (Foreign Tax Credit), Form 3520 / 3520-A (foreign trusts and gifts above the threshold), Form 8621 if you hold any non-US mutual funds (PFIC reporting — punitive default treatment unless QEF or mark-to-market election made on time). On the German side: Anlage AUS for foreign income, Anlage KAP-INV for foreign capital income, NVA Bescheinigung for treaty-based withholding adjustments, exit-tax (Wegzugsbesteuerung) calculations under §6 AStG if you hold significant participations and are giving up German tax residency.
How much you should expect to pay
Cross-border returns cost more than domestic-only returns because the work is genuinely more complex and the liability exposure is higher. In 2026 USD, expect roughly: simple expat return with one or two foreign accounts, $800–$1,500 per year. Moderately complex (foreign rental income, foreign pension, multiple accounts, treaty positions): $1,800–$3,500. Complex (PFICs, trust reporting, exit-tax planning, dual-resident year, business income): $4,000–$8,000+. Hourly rates range from $250 to $600 depending on city and seniority. Boston/NYC/SF tend to be higher than Atlanta/Houston/Miami. Most cross-border firms quote a fixed annual fee after a paid intake call (usually $250–$500 for the intake itself, often credited against the engagement). Ask for the fee structure in writing before signing.
Five questions to ask in the first call
1) "Are you licensed as a deutscher Steuerberater, or do you partner with one?" — Names matter; ask for the firm name and Kammer registration. 2) "How many of your clients have my profile?" (e.g., German citizen with US W-2 income and a German rental property). Specificity beats generality. 3) "Have you handled exit-tax (Wegzugsbesteuerung) planning?" — only relevant if you might leave the US and re-establish German residency, but a good advisor will recognize the question instantly. 4) "What is your approach to PFIC reporting for German Investmentfonds?" — anyone who answers "we just do mark-to-market" without explaining trade-offs is too superficial. 5) "Who actually does the work — you, an associate, or an offshore team?" — important for complex returns where errors are easy and consequences are six-figure penalties.
Using this directory to shortlist
Browse the Accounting & Tax category for German-affiliated tax advisors across the US. Filter by your city or state to find ones near you. Listings marked with a German connection have either a German owner / Steuerberater partnership or are US subsidiaries of German firms. We do not rank or rate advisors — that is for you to evaluate. We do verify the German connection and the basic legitimacy of the practice before approving a listing. Always do your own due diligence: check the US state CPA license at your state's Board of Accountancy, check the Steuerberater registration at the relevant Kammer (e.g., Steuerberaterkammer Berlin), and ask for client references in your specific situation type.
