Form 5472 for Turkey Residents with a US LLC

A Turkey-resident owner of a US single-member LLC must file Form 5472 with a pro forma Form 1120 each year the LLC had a reportable transaction with them. A US-Türkiye tax treaty is in force, and it changes nothing about that filing. If the Revenue Administration has issued you a vergi kimlik numarası, that number goes in the FTIN box.

Türkiye has become a common place to run a US LLC from. Developers and agency owners in Istanbul, ecommerce sellers shipping to US customers, and remote workers who came to Antalya and stayed form Wyoming or Delaware LLCs for Stripe, US business banking, and clients who prefer paying a US entity.

Two features of the Turkish position change the mechanics of the filing compared with a UK or Indian owner. A treaty exists, which leads owners to assume it does something here. And Türkiye issues individuals a real personal tax number, including to foreigners. Neither feature removes the obligation.

If you would rather have the filing done than explained, we prepare and fax the complete package from $149.

Do Turkey residents have to file Form 5472?

Yes, on the same terms as any other non-US owner. Three conditions:

The LLC is a US disregarded entity — a single-member LLC that has not elected corporate treatment.
Its sole member is a non-US person. A Turkish citizen or Türkiye-resident foreigner who is not a US citizen, green card holder or US tax resident qualifies.
There was at least one reportable transaction during the tax year between the LLC and its owner or another foreign related party.

Under Treasury Regulation § 1.6038A-1, for tax years beginning on or after 1 January 2017 and ending on or after 13 December 2017, a foreign-owned US disregarded entity is treated as a corporation separate from its owner solely for the § 6038A reporting rules. That is what pulls a one-person Wyoming LLC into a filing designed for multinationals, and where the owner lives does not switch it off.

Reportable transactions are money, property or services moving between you and your own LLC: contributions in, distributions out, loans either direction, payments for goods or services. Customer revenue is not a reportable transaction. A Stripe payout from a US customer does not go on the form; the transfer you then make from that balance to your personal İş Bankası or Ziraat Bankası account does.

So money wired in to open the LLC's Mercury account is a reportable contribution, everything drawn out since is reportable distributions, and cash lent to cover ad spend is a reportable loan.

The IRS Instructions for Form 5472 state that a penalty of $25,000 may be assessed for failure to file when due and in the manner prescribed, and that a substantially incomplete Form 5472 constitutes a failure to file.

Does the US-Türkiye tax treaty change anything?

Türkiye appears on the IRS list of United States income tax treaties, in the T section alongside Thailand, Trinidad, Tunisia and Turkmenistan, and its entry carries none of the caution notes the same page attaches to Belarus, Hungary and Russia. The instrument published there is the 1996 Convention between the two countries.

What a treaty can do. It allocates taxing rights over income. Its permanent establishment article can matter to whether business profits are taxable in the United States, and its dividend, interest and royalty articles can reduce US withholding on US-source passive income. Whether any of that reaches you is a question for a qualified adviser.

What it does not do. It does not touch Form 5472, which is an information return under IRC § 6038A, not a tax. No article of any US income tax treaty exempts a foreign-owned US disregarded entity from filing it, and no treaty claim substitutes for it. A Türkiye-resident owner files on identical terms to a UAE owner with no treaty at all.

What goes in the FTIN box if you live in Türkiye?

Enter the Turkish tax identification number the Revenue Administration holds for you. Türkiye issues individuals a personal tax number — the vergi kimlik numarası — so most owners here have a real FTIN rather than a workaround.

Foreigners without one apply to the Revenue Administration's Digital Tax Office for a potential tax identification number for foreigners (potansiyel vergi kimlik numarası) — the same number people obtain to open a Turkish bank account. A residence permit is not part of that application.

The Form 5472 instructions require a foreign-owned US DE to enter an FTIN, if any, for each foreign owner in Part II, on line 4b(3); if you have none, enter "None" or "N/A" rather than leaving it blank. Where line 4b(1) has no US identifying number, a self-assigned reference ID goes on line 4b(2), used identically every year.

Read the third column first. It is identical in every row, and that is the point.

Your situation in Türkiye	FTIN box (Part II, line 4b(3))	What the US filing requires
Short stay, no Turkish tax number	The tax number of whichever country does treat you as resident; otherwise "None" or "N/A" plus a reference ID	Form 5472 + pro forma 1120, faxed or mailed
You hold a potential vergi kimlik numarası from the Digital Tax Office	That number	Form 5472 + pro forma 1120, faxed or mailed
Türkiye tax resident under Income Tax Law article 4, number on record	The tax number the Revenue Administration holds for you	Form 5472 + pro forma 1120, faxed or mailed
Residence permit holder, no Turkish tax number yet	"None" or "N/A" plus a reference ID, or apply for the number first	Form 5472 + pro forma 1120, faxed or mailed

If you are a Turkish citizen, use the number the Revenue Administration holds for you as an individual. We could not source the identity-number-to-tax-number mapping from a primary Revenue Administration page, so treat that mechanic as unverified and confirm your number through the Digital Tax Office.

Use your actual Turkish address in Part II, not your US registered agent's. Part II records where the foreign owner is.

Does Turkish tax residency affect the US filing?

No. Turkish residency and the US information return run on different rulebooks.

Turkish residency for individuals sits in article 4 of the Income Tax Law (Gelir Vergisi Kanunu No. 193) on the government legislation portal, mevzuat.gov.tr. Two alternative tests make a person settled in Türkiye: a domicile (ikametgah) in Türkiye, or residing there continuously for more than six months in one calendar year, with temporary departures not breaking the period. Article 3 taxes those settled in Türkiye on income earned inside and outside the country. Article 5 excepts certain people — among them those on a specific, temporary assignment and those who come to study, for treatment or to travel — even beyond six months.

That is outline, not advice: what you owe in Türkiye and which Turkish return you file are questions for the Revenue Administration or a Turkish accountant.

The US side is narrower and firmer:

Becoming a Turkish tax resident does not create a US filing obligation and does not remove one.
Falling short of the six-month test does not remove it either: four months in Istanbul and the rest elsewhere produces the same package.
If your US LLC transacts with a Turkish company you own, that company is a foreign related party — a separate Form 5472 for that party.

Is there a Türkiye digital nomad visa, and does it matter here?

Türkiye does run a digital nomad route, and it changes nothing about Form 5472.

The official Go Türkiye platform publishes the application requirements for the Digital Nomad Identification Certificate, describing it as the first step toward a Digital Nomad Visa: obtain the certificate, then apply at a Türkiye visa centre or consulate with it. The published requirements are applicants aged 21 to 55, a travel document valid at least six months from arrival, a university degree document, a contract showing work for a company outside Türkiye (or a business contract if self-employed), a biometric photo, and proof of monthly income of USD 3,000 or USD 36,000 annually. Eligibility is limited to a published list of nationalities — including the UK, Switzerland, Canada, the USA and most of the EU and EEA, but not everyone — so check it.

Residence permits themselves are issued by the Presidency of Migration Management, so confirm current rules at goc.gov.tr. Either way, immigration status is not tax status: a certificate, a visa or a permit neither creates nor removes a Form 5472 obligation. With no settled country at all, our digital nomad guide covers that case.

How does a Türkiye-based owner actually file?

You cannot e-file: the package goes on paper, and no consumer tax software supports it.

Prepare the pro forma Form 1120 with the LLC's name and address and items B and E, and write "Foreign-owned U.S. DE" across the top of page 1.
Prepare Form 5472 — Part I for the LLC, Part II for you with your Turkish address and FTIN or reference ID, Part III for the related party, Part IV for the listed transaction categories, and Part V with a statement itemising contributions and distributions.
Convert lira figures to US dollars at a reasonable rate for each transaction date, applied consistently, keeping the rate source in your workpapers.
Sign and date it, then fax to 855-887-7737 or mail to Internal Revenue Service, 1973 Rulon White Blvd, M/S 6112, Attn: PIN Unit, Ogden, UT 84201.
Keep the timestamped transmission receipt. The IRS sends no acknowledgement, and a transmission receipt is evidence of transmission, not IRS acceptance of the return.

For a 2025 calendar-year LLC the return is generally due 15 April 2026, with Form 7004 available under the special DE instructions. Dates are in our deadline guide.

Getting it filed from Istanbul or Antalya

The Turkish specifics — a treaty that is real but irrelevant here, a vergi kimlik numarası in the FTIN box, lira conversion, a Turkish company as a possible second related party — are routine once seen.

Form5472 Prep prepares the complete package: Form 5472 with the FTIN and reference ID handled correctly, the pro forma Form 1120, and the Part V statement. A qualified tax accountant reviews each one, we fax it to the IRS Ogden PIN Unit, and you get the timestamped confirmation receipt back. Past years include a reasonable cause cover letter.

$149 standard, ready in 5-7 business days. $199 express, within 3 business days. +$99 per additional past tax year. IRS fax delivery included, so you never send an international fax from Türkiye.

We are not a CPA firm and do not give tax advice, and we do not advise on Turkish tax. We prepare and submit the US information return accurately.

Frequently asked questions

Do I have to file if my LLC made no profit?

Yes, if money moved between you and the LLC. Form 5472 reports related-party transactions, not profit. A contribution, distribution or loan triggers the filing in a loss-making year.

Is there a tax treaty between the United States and Türkiye?

Yes. Türkiye is listed in the T section of the IRS treaty A-to-Z page with no caution note, and the instrument published there is the 1996 Convention. It does not affect Form 5472.

Can I use my Turkish identity number as my FTIN?

Enter the tax number the Revenue Administration holds for you as an individual. We have not sourced that mapping from an official page, so confirm your number through the Digital Tax Office rather than assuming it.

I have no Turkish tax number — what do I write?

Enter "None" or "N/A" in the FTIN block, never a blank, and a self-assigned reference ID on line 4b(2). Or apply to the Digital Tax Office for a potential tax identification number first.

Does a digital nomad visa or residence permit change my filing?

No. Immigration status is not tax status. A Digital Nomad Identification Certificate, a visa or a Turkish residence permit neither creates nor removes the obligation, which follows the LLC and your non-US-person status.

My Stripe payouts go straight into the LLC — reportable?

No. Customer revenue is not a reportable transaction. Reportable is the transfer from the LLC's balance to your Turkish account, plus anything you put in or lend the LLC.

I have never filed and the LLC is two years old — what now?

File every outstanding year as soon as you can, with a reasonable cause statement, before the IRS writes to you. Our late filing guide sets out the sequence.

A treaty settles which country may tax what. It says nothing about whether an information return is due, and for a Türkiye-based owner it is due on the same terms as for anyone else.

Start your filing — about 15 minutes — or read the FTIN and reference ID guide first if the Part II boxes are holding you up.
