US Company Formation from Estonia (2026): Estonian OÜ vs US LLC vs Delaware C-Corp, the 22% Distribution Tax, Low-Tax Territory Rules, e-Residents and the US–Estonia Treaty
How to set up a US company from Estonia: why an Estonian OÜ already defers tax until distribution at 22/78, how Estonia taxes a resident's US LLC and its distributions, the low-tax territory rule for controlled foreign companies, permanent establishment of a foreign company managed from Estonia, e-Residency vs a US LLC for non-residents, the US–Estonia treaty (dividends 15%/5%, interest 10%, royalties 5%/10%), Delaware flips for Tallinn start-ups, euro examples, costs.
Estonia gave the world two ideas that matter here. One is e-Residency, which lets anyone run an Estonian company online. The other is a corporate tax that applies only when profits are distributed, so a company that reinvests pays nothing. Since 2025 that distribution tax is 22% (22/78 of the net amount), the planned rise to 24% for 2026 was cancelled, and the temporary security tax was scrapped.
Those two ideas shape the US question in Estonia. A resident who already has an OÜ gets tax deferral at home, so a US LLC adds little. A start-up raising US money still needs a Delaware corporation. And e-residents abroad often compare an Estonian OÜ with a US LLC, sometimes without realising that neither is taxed where they think. This guide covers all three cases, with the US–Estonia treaty.
In short: Estonian residents can own 100% of a US LLC or C-Corporation, formed remotely. An Estonian OÜ pays no tax on retained profits and 22/78 on distributions, so it already does what many people want from a US LLC. Estonia generally treats a US LLC as a foreign company; distributions to a resident individual are taxable if no tax was paid abroad, and low-tax territory rules can tax a resident on the income of a controlled foreign company. A foreign company managed from Estonia can have an Estonian permanent establishment. The US–Estonia treaty limits US withholding on dividends to 15% (5% for companies owning 10% or more), on interest to 10% and on royalties to 5% or 10%. With UCB, a Delaware corporation with EIN is $358 and a Wyoming LLC with EIN is $249, all-in.
Three structures side by side
| Estonian OÜ | US single-member LLC | US Delaware C-Corporation | |
|---|---|---|---|
| Tax on retained profits | 0% | 0% in the USA if no US business | 21% federal plus state |
| Tax when profits are paid out | 22/78 on the net distribution (paid by the OÜ) | None in the USA; Estonian tax on the owner | 15% US withholding (treaty) for an individual |
| How Estonia treats it | Estonian company | Foreign company | Foreign company |
| Investors | Some European investors accept it | Rarely | Standard |
| Banking | Estonian and EU banks and fintechs | US banks and fintechs | US banks and fintechs |
For an Estonian resident running a services business, the OÜ is already the efficient choice. The US entities make sense for specific reasons, not for tax.
How Estonia treats a resident's US LLC
Classification and distributions
The IRS disregards a single-member LLC. Estonia generally treats a US LLC with limited liability as a foreign legal person. When the LLC distributes money to an Estonian resident individual:
- dividends from a foreign company are exempt in Estonia only if tax was paid on the underlying profit or withheld from the dividend abroad;
- a disregarded LLC pays no US tax and the US withholds nothing on its distributions;
- so the distribution is generally taxable in Estonia at 22%, declared on the individual's return.
Low-tax territory companies
Estonia's Income Tax Act lets the tax authority tax a resident individual on the income of a foreign company they control in a low-tax territory, meaning broadly where the tax on the company's profit is less than a third of the Estonian tax that would apply. A disregarded US LLC that pays no US tax can fall within that description in practice, even though the USA is not a tax haven. Ask your adviser whether the rule applies to your LLC.
Permanent establishment
A foreign company whose business is run from Estonia can have an Estonian permanent establishment, which Estonia taxes on profits taken out of the establishment, much as it taxes an OÜ. A US LLC run from a home office in Tartu may therefore end up in the Estonian tax net anyway.
Example: a Tallinn developer
These are illustrative figures, not a client case, at €0.92 to the dollar.
Kristjan is a back-end developer in Tallinn who earns US$100,000 (about €92,000) a year from US clients through his OÜ. He pays himself a modest salary, which is taxed with social tax, and leaves the rest in the OÜ, which pays no tax until he distributes it. When he distributes €30,000, the OÜ pays 22/78 of it, about €8,460.
A US LLC would not improve that. If the LLC is managed from Tallinn, it can have an Estonian permanent establishment; if not, its distributions to Kristjan are generally taxable at 22% in Estonia, and the low-tax territory rule may tax him even earlier. He keeps the OÜ. His largest client insists on a US vendor, so the OÜ forms a small Wyoming LLC that contracts with the client and pays the OÜ for the work.
e-Residents: OÜ or US LLC?
Many e-residents living outside Estonia ask whether they should form an Estonian OÜ or a US LLC. Two facts are often missed:
- e-Residency is not tax residency. An e-resident living in Lisbon or Bangalore is taxed where they live. An OÜ run entirely from abroad can be taxed in the founder's country of residence, because its place of management is there, and it may also have an Estonian obligation.
- A US LLC is also taxed where its owner lives, in most countries' view, unless the owner lives somewhere that ignores foreign income.
The choice should be made on practical grounds: where your clients are, which currency you are paid in, and which banks and payment platforms you need. Then check how your country of residence treats the entity. See our country guides, for example India, Germany or Portugal, and LLC vs Inc for non-residents.
US C-Corp formation from Estonia
US tax position
A US corporation pays 21% federal tax on its profits plus state tax, and files Form 1120 and Form 5472 every year (see the 21% corporate tax explained and the C-Corp guide for non-residents). Under the treaty, its dividends to an Estonian OÜ owning 10% or more carry 5% US withholding. An OÜ that receives such a dividend can generally pass it on without further Estonian corporate tax under the participation rules.
The Delaware flip
Estonia produced some of Europe's best-known start-ups, and many moved their parent to Delaware before raising from US investors. The usual sequence:
- Founders form a Delaware C-Corporation.
- They exchange their OÜ shares for Delaware shares, so the OÜ becomes a wholly owned subsidiary.
- US investors buy preferred shares in the Delaware company.
- The OÜ continues to employ the team in Estonia and invoices the Delaware company for development at cost plus a margin.
Estonia does not tax the OÜ on retained profits, which suits a subsidiary that reinvests. Founders should take advice on how the share exchange is treated in Estonia. See raising US investment as a foreign founder and US LLC for SaaS founders.
An OÜ's US sales subsidiary
An established Estonian company hiring US staff usually forms a Delaware corporation subsidiary. The subsidiary pays US tax on its margin, and the OÜ documents transfer pricing. See US subsidiary for a foreign company.
US LLC formation from Estonia
US tax position
A single-member LLC with a non-resident owner pays no US income tax if the owner works from Estonia and the LLC has no US office, employees or dependent agents (see effectively connected income explained). It files Form 5472 with a pro forma Form 1120 every year, and the penalty for missing it is $25,000 (see Form 5472 explained).
When an LLC fits
- As a small US contracting entity owned by an OÜ, for clients who insist on a US vendor.
- For US real estate, where an LLC is standard for liability purposes (see real estate investment LLC for foreigners).
- For e-residents who live in a country that treats the LLC favourably, after checking with a local adviser.
The US–Estonia treaty
The treaty in force since 2000 limits US withholding on payments to Estonian residents:
| Payment from the USA | Treaty rate |
|---|---|
| Dividends to an individual | 15% |
| Dividends to a company owning 10% or more | 5% |
| Interest | 10% (0% in some cases) |
| Royalties | 5% for industrial equipment, 10% for others |
It also limits US tax on business profits to a US permanent establishment, and contains a limitation on benefits article. Claim it on Form W-8BEN or W-8BEN-E (see W-8BEN-E vs W-8BEN explained). Estonians are eligible for the E-2 treaty investor visa.
Which state
- Delaware for start-ups and subsidiaries.
- Wyoming or New Mexico for a small LLC owned by an OÜ.
See best state for non-residents and the state selector.
What it costs
UCB's prices include state fees and the first year of registered agent service:
- Delaware corporation with EIN: $358.
- Wyoming LLC with EIN: $249, or $348 with a US bank account application.
A Delaware corporation costs $578 a year to keep active. A Wyoming LLC costs $121 a year, or $421 with the annual federal return. A US business address with your own suite number is $60 a year. See what a US LLC costs every year.
Documents and banking
For an individual, your passport or Estonian ID card and proof of address. For an OÜ, an e-Business Register extract in English and a management board resolution. The e-Residency card is a digital identity card, not a travel document; US banks want a passport. See US business bank accounts for non-residents and Stripe for non-residents.
Mistakes to avoid
- Forming a US LLC for tax deferral that an OÜ already provides.
- Not declaring LLC distributions in Estonia because no US tax was withheld.
- Ignoring the low-tax territory rule for a controlled LLC that pays no US tax.
- Assuming e-Residency makes you an Estonian tax resident.
- Missing Form 5472 in a year when no US tax was due.
Frequently asked questions
Is a US LLC better than an Estonian OÜ for an Estonian resident? Rarely. The OÜ already pays no tax on retained profits, and Estonia generally taxes LLC distributions at 22%.
How does Estonia treat a US LLC? Generally as a foreign company. Distributions are taxable if no tax was paid abroad, and the low-tax territory rule can apply.
Is there a US–Estonia tax treaty? Yes. Dividends 15% (5% for companies owning 10% or more), interest 10%, royalties 5% or 10%.
Does e-Residency make me an Estonian taxpayer? No. Tax residence depends on where you live. An OÜ run from abroad can be taxed where you live.
Does my US LLC pay US tax? Not if it has no US office, staff or agents. It files Form 5472 and a pro forma 1120 every year.
