How to Start a US LLC From Turkey

Turkey has a comprehensive income tax treaty with the United States, in force since 1998, a genuine point of difference from several Latin American countries covered elsewhere in this series that have no such treaty at all. The treaty provides mutual relief mechanisms and clarifies tax residency in dual-resident situations, and Turkey's domestic law separately allows a foreign tax credit for tax actually paid abroad. In practice, this matters less for a typical single-member LLC than the treaty's existence might suggest, since a non-resident-alien-owned LLC earning non-US-source income usually owes $0 US federal tax to begin with, leaving little for either the treaty or the credit to actually offset, but the treaty becomes more relevant once the business scales into US-source income or a later corporate election changes what the LLC itself pays.

Putting it together: form the LLC (Wyoming and Delaware remain the two most common choices), get the EIN using the international applicant line above, open a Mercury or Relay account, since neither restricts Turkey, and keep clear documentation that your LLC's income is active business revenue rather than passive holdings, since that's the condition actually keeping most Turkish founders' LLCs out of CFC scope. Don't rely on the same 'the US isn't a low-tax jurisdiction' comfort that works for founders from some other countries in this series; Turkey's test looks at what your LLC actually paid, not what the US generally charges, so the active-income documentation is what's doing the real protective work here.

Turkey's software, e-commerce, and freelance-consulting sectors have grown quickly enough that a US LLC has become a standard tool for founders trying to insulate their business from lira volatility and get the same Stripe, PayPal, and Amazon access that founders anywhere else expect by default. For these founders, a US LLC solves problems a Turkish Limited Şirket often can't from the outside: direct USD invoicing that removes exchange-rate exposure from client billing, faster and cheaper formation than most Turkish corporate structures aimed at international clients, and immediate familiarity with US-based payment processors and enterprise clients. What most guides written for Turkish founders miss is that Turkey's own controlled foreign company rules work differently from the low-tax-jurisdiction tests used by several other countries covered in this series, and the difference matters more than it first appears.

Getting an EIN as a Turkish founder works exactly like it does for any other non-US resident. Without a US Social Security Number or ITIN, you can't use the IRS's online EIN application — you'll file Form SS-4 and either call the IRS's international applicant line (267-941-1099, staffed 6am-11pm ET, for international applicants only) to receive the EIN over the phone, or fax the SS-4 (855-215-1627 from within the US, 304-707-9471 from outside) for a roughly 4-business-day official turnaround that often takes 1-2 weeks in practice. Mailing to Cincinnati, OH takes 4-5 weeks and should be a last resort. On Line 7b, write 'Foreign' or 'N/A' rather than leaving it blank. The responsible party listed must be the actual Turkish owner, not EasyBrise or any formation agent. If you lose your CP 575 confirmation notice, request Form 147C, a letter, not a duplicate, instead. Don't skip Form 5472 plus a pro forma 1120 each year; the penalty for missing it starts at $25,000.

On the funding side, the Turkish lira is fully convertible, and there's no comprehensive capital control regime blocking outward investment the way some countries in this series impose hard remittance caps. The one friction point worth knowing: a 2019 government decree imposed a settlement delay, not a ban, on individual foreign-exchange purchases above $100,000, meaning a single large transfer above that threshold may process more slowly than a series of smaller ones. For most founders capitalizing a US LLC with a modest initial amount, this rarely matters in practice; it becomes relevant mainly for founders planning a substantial single upfront capital injection rather than the more typical bootstrapped approach most single-member LLCs use.

Turkey's CFC rules apply when Turkish resident individuals or companies, jointly or severally, directly or indirectly, hold 50% or more of a foreign company's shares, dividend rights, or voting rights, a single-member LLC's 100% owner clears this threshold easily. But ownership alone doesn't trigger CFC status; three additional conditions all have to be met together: at least 25% of the foreign company's gross income must be passive (interest, royalties, dividends, rents, and similar), the foreign company must bear an effective tax burden below 10%, and its annual gross revenue must exceed the lira equivalent of roughly TRY 100,000, a very low bar that almost any operating LLC clears immediately. All three conditions have to be satisfied at once for the CFC rules to apply and pull the LLC's profit into your Turkish tax return currently, whether or not it's distributed.

Turkish lira volatility is a genuine, ongoing driver behind why founders want a US LLC and USD-denominated business in the first place, not just an incidental backdrop. Persistent depreciation and elevated inflation over recent years have made holding business revenue in lira, even briefly, a real erosion risk for founders who bill and hold funds domestically. A US LLC with a Mercury or Relay account lets a Turkish founder invoice, hold, and reinvest business revenue in USD, converting to lira only when and if funds are actually needed at home, rather than being forced to convert US client payments into lira immediately and absorb the exchange-rate exposure on both sides of every transaction. This is less a tax-planning consideration than a straightforward treasury-management one, but it's the single most common reason Turkish founders give for forming a US LLC in the first place.

On the banking side, Turkey is not on Mercury's or Relay's published prohibited-country list, and Turkish founders go through the same standard non-resident application process, passport, LLC formation documents, and EIN, as founders from most other countries in this series. There's no distinct Turkey-specific hurdle at the account-opening stage; the practical complexity for Turkish founders sits in the CFC classification question above, which matters for Turkish tax filings, not in getting Mercury or Relay to approve the account itself.

What actually protects most Turkish founders is the passive-income condition, not the tax-rate one. For the CFC rules to apply, at least 25% of the foreign company's gross income has to be passive, interest, royalties, dividends, and similar. A typical operating LLC running a SaaS product, an e-commerce store, or a consulting practice earns active business income, not passive income, so this condition usually isn't met even when the tax-burden condition technically is. Since all three conditions must be satisfied together, failing just this one keeps the LLC out of CFC scope regardless of how little US tax it pays. The practical takeaway: document that your LLC's revenue is genuinely active business income rather than passive holdings, since that's the condition actually doing the protective work here, not the tax-rate question that reassures founders in other countries.

Here's where Turkey's test works differently from several other countries in this series, and it's worth understanding precisely: the low-tax condition looks at the actual effective tax burden the foreign company bears, not the country's statutory tax rate. Countries like China, Taiwan, and Iceland ask whether the country itself is generally low-tax; Turkey asks what your specific company actually paid. A non-resident-alien-owned single-member LLC earning non-US-source income typically pays $0 US federal tax, since it has no effectively connected income to tax in the first place. That $0 effective tax burden technically satisfies Turkey's below-10% condition, the reassurance other countries' founders get from 'the US isn't a low-tax country' doesn't work the same way here, because Turkey isn't asking about the US's statutory rate; it's asking about what your LLC actually paid, which for many founders really is $0.
