Do I need to declare my US LLC income to the Finanzamt (German tax office)?

German tax residents are subject to unlimited tax liability on worldwide income. If your US LLC generates income and you are a German tax resident, that income is generally subject to German income tax. The US-Germany tax treaty and the foreign tax credit provisions may reduce double taxation, but German tax liability on US LLC income is a real possibility that requires advice from a German Steuerberater (tax advisor).

Does the US-Germany tax treaty eliminate my Form 5472 requirement?

No. The US-Germany double taxation treaty (DTA) covers income taxes, not information return filing requirements. Form 5472 is an information return with no associated tax payment — treaty provisions cannot be invoked to avoid this filing obligation.

I have a GmbH in Germany that owns a US LLC. Who files Form 5472?

The U.S. entity's classification, ownership, and related-party transaction facts determine whether it must furnish Form 5472 and how a German GmbH is reported. Do not assume that ownership alone makes every transaction reportable; confirm the current IRS instructions and the entity's facts.

My US LLC address is my German home address. Is that okay?

You should use your LLC's registered agent address in the US as the LLC's primary address on federal filings. Using a German home address may create confusion and is not recommended. A US registered agent address (like your Delaware agent's address) is the proper address to use on the pro forma Form 1120 and Form 5472.

Do I need a US ITIN or can I use my German tax ID (Steueridentifikationsnummer)?

German residents who are foreign owners of US LLCs must obtain a US ITIN (Individual Taxpayer Identification Number) to be identified on Form 5472. Your German Steueridentifikationsnummer (11-digit German TIN) is not accepted as a substitute. Apply for a US ITIN using IRS Form W-7.
