US Trust Taxation in Germany: A High-Risk Conflict for Heirs

Besteuerung US Trust

Quick Summary: US Trust taxation in Germany depends on the trust’s structure. If the trust is ‘opaque,’ beneficiaries face attribution of income under § 15 AStG, meaning they pay tax on income even without receiving distributions (‘Dry Income’).

Navigating US Trust taxation in Germany is vital for residents. Many people use trusts for estate planning in the USA. However, the German tax system treats these structures differently. This often creates a “tax nightmare” for beneficiaries living in Germany. Therefore, you must understand how the Finanzamt views your foreign assets.


German law does not recognize the “Trust” concept. This is because ownership in Germany is absolute. In the US, ownership is split between a Trustee and a Beneficiary. Consequently, German authorities must “translate” your US Trust into German categories.

Sometimes, they view it as a foreign foundation. In other cases, they may simply ignore the structure. Furthermore, the exact classification determines your total tax burden.


2. The § 15 AStG Trap: Taxation on “Dry Income”

A major risk regarding US Trust taxation in Germany is the attribution of income. This occurs under Section 15 of the Foreign Tax Act (AStG).

If a trust is “opaque,” the income is attributed to the German resident. Therefore, you might owe taxes on money still sitting in a US bank. This is often called “Dry Income.” It means you face a tax bill without receiving an actual distribution. This tax treatment aligns with the BFH ruling of July 3, 2019 (II R 6/16), which confirms that assets held in an irrevocable foreign trust can be attributed to German residents if they maintain a certain level of control or entitlement.


3. Inheritance and Gift Tax: The 30%–50% Risk

Germany’s Inheritance and Gift Tax Act (ErbStG) applies to trust distributions. However, the rates are often surprisingly high.

Normally, children enjoy high tax-free thresholds of €400,000. But the Finanzamt often classifies a trust as an “unrelated third party.” Consequently, you might be placed in Tax Class III. This leads to tax rates of 30% to 50%. Moreover, your exemption drops to a mere €20,000. The German Federal Fiscal Court recently clarified the distinction between income tax and gift tax regarding trust distributions in its ruling of June 25, 2021 (II R 13/19), emphasizing the risk of Tax Class III classification.


4. Revocable vs. Irrevocable: The German View

The tax treatment depends on the Grantor’s power.

  • Revocable Trusts: These are usually seen as “transparent.” The assets still belong to the Grantor.
  • Irrevocable Trusts: These are the main targets for § 15 AStG. Once the Grantor loses control, the trust becomes a separate taxable pocket.

Therefore, the transition from revocable to irrevocable is a critical tax event.


5. Practical Checklist: Protecting Your Assets

Do not wait for a query from the Finanzamt. Instead, perform a document-driven analysis now. You should follow these steps:

  1. Gather Documents: Collect the Trust Deed and all Amendments.
  2. Verify Control: Determine if the Trustee has full discretion.
  3. Report Early: You must report foreign trust interests within one month.
  4. Consult Experts: Use the US-Germany Double Taxation Treaty to your advantage.
