US Germany Estate Tax Treaty: What Families Need to Know After a Death

How the Treaty Prevents Double Taxation

When an American citizen dies in Germany, two countries want to tax the estate. The US imposes a federal estate tax on worldwide assets of its citizens. Germany imposes inheritance tax (Erbschaftsteuer) on assets located within its borders — and sometimes on the entire estate if the deceased was a German tax resident.

The 1980 US-Germany Estate and Gift Tax Treaty resolves this overlap by assigning primary taxing rights based on where the assets sit. Real property in Germany gets taxed by Germany. Bank accounts and securities are generally taxed by the country where the deceased was domiciled. Where both countries do tax the same asset, the treaty guarantees a credit mechanism so families aren't paying inheritance tax twice on the same euros.

The practical effect: if your family member was an American tourist or short-term resident who died in Germany, Germany taxes only the German-situs assets (bank accounts held at German banks, real property, business interests). The US taxes the worldwide estate but grants a dollar-for-dollar credit for whatever Germany collected.

German Inheritance Tax Rates and Exemptions

Germany's inheritance tax rates range from 7% to 50%, depending on the relationship between the heir and the deceased and the value of the inherited assets.

The allowances depend on the relationship and on whether the acquisition is subject to unlimited or limited German tax liability. General examples are a €500,000 allowance for a surviving spouse and €400,000 for a child; a nonresident case must be calculated under the applicable German rules and treaty.

Do not apply a flat nonresident allowance to a German bank balance without checking the applicable rules. A €50,000 savings account could fall below a €500,000 spouse allowance if that allowance applies, while a limited-tax case requires a separate calculation.

The Unbedenklichkeitsbescheinigung: Your Tax Clearance Certificate

A German bank may establish account access once the heirs prove their legal authority, but it will block the physical transfer of funds to a foreign account until the local tax office (Finanzamt) issues an Unbedenklichkeitsbescheinigung — the tax clearance certificate. This document confirms that the inheritance-tax obligations tied to those assets have been settled or secured.

To get it, heirs must file an inheritance tax return (Erbschaftsteuererklärung) with the Finanzamt that has jurisdiction over the estate. For non-resident decedents who left assets in Germany, that's typically the Finanzamt in the district where the assets are located.

The filing requires the German death certificate (Sterbeurkunde), proof of heir status (an Erbschein or the will with a court-certified translation), and a complete inventory of German assets. Processing takes anywhere from several weeks to several months — and the physical transfer of funds abroad remains blocked until the certificate arrives.

Filing Obligations on the US Side

For a decedent who dies in 2026, the federal basic exclusion is $15 million, and the executor generally must file IRS Form 706 above that threshold (or to elect portability), reporting worldwide assets including German holdings. Additional information returns such as Forms 3520 or 8938 depend on who held or received the assets and on the applicable reporting thresholds; they are not automatic in every German-inheritance case.

The treaty's credit mechanism works through Form 706, Schedule P — the executor claims a credit for German inheritance tax paid against the US estate tax liability. This credit is limited to the lesser of the actual German tax or the proportional US tax attributable to the German assets.

Families below the federal estate tax exemption still need to handle the German side. The German Finanzamt doesn't care about US exemption thresholds — it taxes German-situs assets according to German rates and German exemptions.

Common Mistakes That Cost Families Money

The biggest mistake is assuming the treaty eliminates all German tax. It doesn't — it prevents double taxation by ensuring you get credit for what you paid to one country against the other. If the German tax exceeds the US credit (common with small estates below the US exemption), the family absorbs the German tax as a net cost.

The second mistake is delaying the German filing. The Finanzamt charges interest on late returns, and the bank freeze grinds on until clearance arrives. Heirs who've already applied for an Erbschein should file the tax return simultaneously rather than waiting for the inheritance certificate to come through.

The American Dies in Germany — Family Emergency Guide walks through the full tax clearance process alongside the bank-unlocking and Erbschein application, so you handle all three in parallel instead of discovering each requirement sequentially.

Frequently Asked Questions

Does the US-Germany estate tax treaty apply to all types of assets?

The treaty covers real property, business assets, bank accounts, securities, and tangible personal property. Different asset categories may be assigned to different countries for primary taxation rights. Real property is always taxed by the country where it sits. Movable property generally follows the domicile of the deceased.

Can US-based heirs claim the higher German exemptions?

Eligibility for the higher German allowances depends on the residence and tax-liability facts of the decedent and heirs, together with any applicable treaty rules. For American tourists or short-term visitors who die in Germany, do not assume a fixed €2,000 allowance; the treaty does not automatically replace the applicable German calculation.

How long does the Unbedenklichkeitsbescheinigung take to arrive?

Processing times vary by Finanzamt and case complexity. Expect several weeks to several months; complex estates with multiple asset types, contested inheritances, or incomplete documentation can take six months or longer.
