US LLC Owned From Belgium: Form 5472, Taxes and Filing

A US LLC owned from Belgium has a yearly IRS filing even if it earns nothing in the US. This guide shows the filings, the Belgian tax ID that goes on Form 5472, and what it means that the US has a tax treaty with Belgium.

Quick answer

Does a resident of Belgium who owns a US LLC have to file with the IRS?

Yes, if the LLC had a reportable transaction with you, and forming and funding it counts. A single-member US LLC owned by a resident of Belgium files Form 5472 with a pro forma Form 1120 each year, usually by April 15 for a calendar year, even with no income. The US has an income tax treaty with Belgium, which affects how profits and US-source payments are taxed, not whether Form 5472 is due.

What a US LLC owned from Belgium files each year

A US LLC with a single foreign owner is a disregarded entity for income tax, but the IRS treats it as a corporation for one purpose: reporting its dealings with its owner. That is why an owner in Belgium with no US customers, no US office and no profit can still owe a US filing every year.

Filing	When it applies	Source
Form 5472 with a pro forma Form 1120	Every year the LLC has a reportable transaction with its foreign owner, including money you put in or take out	IRS
BE-13 survey	Generally within 45 days when a foreign person sets up or buys a US business	BEA rule
State annual report or tax	Depends on the state; see US LLC annual fees by state	State filing office
Form 1040-NR	Only if the LLC has income effectively connected with a US trade or business	IRS

The penalty for a missing or substantially incomplete Form 5472 is US$25,000, and it grows if the failure continues after an IRS notice (IRS).

What we need from an owner in Belgium

To prepare the filing for an owner in Belgium, we ask for:

Your passport and your home address in Belgium
Your tax ID: For a resident of Belgium, this is usually your 11-digit Belgian identification number (OECD tax ID sheet).
The LLC's formation documents and EIN letter
Bank and payment account statements for the year, so every transfer between you and the LLC can be listed, converted from euros where needed

The IRS wants all amounts in US dollars and the same tax ID used every year (IRS).

Is there a US tax treaty with Belgium?

Yes: the IRS lists Belgium among the countries with a US income tax treaty (IRS treaty list). The treaty does not remove Form 5472. What it can change is how much US tax applies to the LLC's profit and to payments you receive.

Question	With the treaty	Source
Is the LLC profit taxed in the US?	Generally only the part attributable to a US permanent establishment, such as an office or dependent agent in the US	Form 8833
Do I have to tell the IRS I rely on that?	Yes, on Form 8833 with the return; not disclosing costs US$1,000	Form 8833
Can I get lower withholding on US dividends, interest or royalties?	You can claim it on Form W-8BEN by naming Belgium; otherwise 30% generally applies	W-8BEN, Pub 515

Treaty benefits depend on the exact article and on whether you qualify under it, so we check the treaty text before relying on it.

Reporting the LLC in Belgium

Belgian founders use a US LLC to sell software and services to US customers and to hold US contracts.

We do not advise on the tax law of Belgium. Your local adviser decides how the LLC is reported at home, and we give them the US returns and numbers so both sides match.

Common questions

Does a resident of Belgium have to file Form 5472 for a US LLC?

Yes, if the single-member LLC had a reportable transaction with you in the year, which includes forming it and putting money in. It is filed with a pro forma Form 1120. The penalty for not filing is US$25,000.

Which tax ID from Belgium do you need from me?

Your 11-digit Belgian identification number. The IRS asks for the same foreign tax ID every year.

Does the United States have a tax treaty with Belgium?

Yes. Belgium is on the IRS list of US income tax treaties. The treaty can limit US tax on business profits to profits attributable to a US permanent establishment, a position disclosed on Form 8833, and lets you claim treaty rates on Form W-8BEN.

Does an LLC owner in Belgium file a US income tax return?

Usually only Form 5472 with the pro forma Form 1120 is filed. A Form 1040-NR is needed if the LLC has income effectively connected with a US trade or business, and the treaty may limit US tax to profits attributable to a US permanent establishment.
