U.S. LLC Taxes for Turkish Founders: Form 5472 and the Tax Treaty

Turkish e-commerce sellers, software teams, and freelancers have turned to U.S. LLCs in large numbers to sell on American marketplaces and collect payments in a stable currency. Turkey (Türkiye) has an income tax treaty with the United States. That treaty affects how income is taxed. It does not replace the yearly Form 5472.

The yearly federal filing: Form 5472 with Pro Forma 1120

When a U.S. LLC has a single owner who is not a U.S. person, the IRS treats it as a foreign-owned disregarded entity. Since 2017, these companies have had to report their dealings with their owner on Form 5472, attached to a Pro Forma Form 1120. It is an information return. It does not calculate tax. It tells the IRS what moved between you and your company during the year.

The return is filed under the LLC's EIN and is sent to the IRS by fax or mail, not through standard e-filing. For a fuller explanation, read Form 5472 Explained.

What counts as a reportable transaction for a Turkish owner

Almost any movement of money or value between you and the LLC counts. Common examples:

• You pay formation and registered agent fees with a personal card.
• You send capital from your Turkish bank account so the LLC can buy inventory or run advertising.
• You distribute profit from the LLC to your personal account in Turkey.

Sellers who hold stock in U.S. warehouses should take extra care. Inventory in the United States can change whether you have U.S. taxable income, and it makes accurate records of what you put in and took out even more important.

Do you owe U.S. income tax? How the treaty fits in

A single-member LLC owned by a non-U.S. person is normally a "disregarded entity". The LLC does not pay U.S. income tax itself. Instead, the IRS looks at you, the owner.

The United States and Turkey have an income tax treaty. Under it, the business profits of a resident of Turkey are generally taxable in the U.S. only if they are connected to a permanent establishment there, such as a U.S. office or staff. The treaty may also lower the standard 30% withholding on certain U.S.-source payments, such as dividends and royalties.

Two cautions apply. Treaty benefits are not automatic and have to be claimed properly. And holding stock in a U.S. warehouse or using U.S.-based people can change the answer. Whether you owe tax or not, the Form 5472 filing still applies.

Tax forms U.S. platforms will ask you for

Payment processors, marketplaces, and U.S. clients often ask for a tax form before they pay you. Because your LLC is disregarded and you are its foreign owner, the correct form is generally a Form W-8BEN in your own name, not the Form W-9 that U.S. owners use. Giving the wrong form can lead to incorrect withholding or to income being reported to the IRS as if you were a U.S. taxpayer.

State filings

Your LLC also answers to the state where it was formed. Wyoming requires an annual report, due on the first day of the month the company was formed. Delaware charges LLCs a yearly tax due June 1. Florida requires an annual report between January 1 and May 1. New Mexico does not require an annual report from LLCs. Missing a state filing can lead to late fees and, in time, the company being dissolved. See our state filings guide.

Other filings to know about

• FBAR. If the LLC holds accounts outside the United States with more than $10,000 combined at any point in the year, an FBAR is also due.
• BOI report. At the time of writing, LLCs formed in the United States are exempt from FinCEN's beneficial ownership report. This does not affect Form 5472, which is an IRS requirement.

The Turkish side

Turkey taxes residents on their worldwide income, so profit from a U.S. LLC is normally relevant to your return with the Revenue Administration (GİB). We prepare U.S. filings only, so please confirm the Turkish side with a local adviser (mali müşavir). Filed U.S. returns support what you declare at home.

If you have missed earlier years

Many owners learn about Form 5472 a year or two after forming the company. The safest step is to file every missing year before the IRS writes to you, with a reasonable cause statement explaining the delay. Read more about late filings and catch-up.

What to keep ready each year

• The LLC's formation documents and EIN confirmation letter
• Your passport details and home address
• All statements for the LLC's bank and payment accounts
• A list of money you put into the company and money you took out, with dates
• Any company costs you paid personally

Common questions from Turkish owners

Does the U.S. tax treaty with Turkey mean I do not have to file Form 5472?

No. The treaty deals with which country may tax certain income. Form 5472 is an information return, and the treaty does not cancel it. A foreign-owned U.S. LLC with reportable transactions still files each year.

Does the treaty reduce my U.S. tax?

It can. Under the treaty, business profits are generally taxable in the U.S. only where they are connected to a permanent establishment there, and withholding on certain payments may be lower than the standard 30%. Treaty benefits have to be claimed correctly, so they should be reviewed for your facts.

I sell on Amazon in the U.S. through my LLC. Does that change anything?

It can. Form 5472 is still required. In addition, holding stock in U.S. warehouses may affect whether you have U.S. taxable income, so your facts should be reviewed before you assume no tax is due.

What if I have missed one or more years?

File the missing years as soon as you can, before the IRS contacts you. A reasonable cause statement explaining why the returns are late can be included with the filing.
