Estonian OÜ vs UK Ltd vs US LLC for Non-Residents: Full Comparison (Tax, Setup Time, Maintenance)
For a non-resident founder, all three of these structures work — they just solve different problems. An Estonian OÜ is the strongest all-rounder when you want EU-market access, euro invoicing, and 0% tax on profit you reinvest, all set up online through e-Residency. A UK Ltd wins on plain global name recognition and a flat, fast setup. A US LLC (Delaware or Wyoming) wins when your customers, payment processors, and investors are American and you want pass-through taxation. This guide puts the three side by side on tax, setup time, banking, and the real annual cost — with the honest caveats each one carries in 2026.
The short answer
Estonian OÜ: 0% corporate tax on retained profit, 22% (as 22/78) only when you distribute; €265 state fee, formation in about 1 business day once you hold e-Residency; VAT 24% above €40,000 turnover.
UK Ltd: corporation tax 19% up to £50,000 profit, 25% above £250,000 (marginal relief between); Companies House fee £100 online (since 1 February 2026); ~24-hour setup; 0% UK withholding on dividends to non-residents; VAT threshold £90,000.
US LLC (Delaware/Wyoming): pass-through — no federal entity tax, profit lands on your personal return; Delaware $300/yr franchise tax, Wyoming ~$60/yr report; foreign-owned single-member LLCs must file Form 5472 + a pro-forma 1120 (up to $25,000 penalty if you skip it).
Banking is the real friction everywhere: pure non-residents usually open an EMI/fintech account (Wise, Payoneer, Revolut, Mercury), not a classic branch bank.
None of these makes you tax resident: e-Residency and any of these companies do not change where you personally pay tax — you still owe personal tax where you actually live.
Best fit: Estonia for EU access + low-admin reinvestment, the UK for credibility and EU-adjacent trade, a US LLC for selling into the US and using Stripe and US banking.
The big comparison table: Estonian OÜ vs UK Ltd vs US LLC at a glance
Here is the full three-way comparison for a non-resident founder in 2026. Read down the column that matches where your customers and money will actually sit. The Estonian OÜ tends to win on retained-profit tax and remote management, the US LLC on pass-through simplicity and US-market fit, and the UK Ltd on plain global recognition. Every figure below has its currency and year so you can lift a single row and it still stands on its own.
Factor | Estonian OÜ | UK Ltd | US LLC (Delaware / Wyoming) |
|---|---|---|---|
Corporate tax treatment | 0% on retained/reinvested profit; 22% on distributed profit (as 22/78 of the net payout) | 19% up to £50k profit, 25% above £250k, marginal relief between — charged whether or not you distribute | Pass-through: no federal entity tax; profit is attributed to you personally |
Personal / withholding angle (non-resident) | No separate dividend withholding beyond the 22/78 already paid; you still owe personal tax where you live | 0% UK withholding on dividends to non-residents; your home country taxes the dividend | Taxed personally where income is taxable; US tax if income is ‘effectively connected’ (Form 1040-NR); passive US income can face 30% withholding |
Setup time | ~1 business day online — but first obtain the e-Residency card (~3–8 weeks) | ~24 hours online | 1–7 business days (state filing + EIN; EIN slower without SSN/ITIN) |
Setup cost (first year, government + prerequisites) | €265 state fee + €100–€150 e-Residency card | £100 Companies House fee (online, since 1 Feb 2026) | ~$100–$110 state filing (EIN is free) |
Annual maintenance cost (basics) | €0 fee to file the annual report + €200–€400 legal address & contact person + accounting | £50 confirmation statement + registered office + accounting | DE $300/yr franchise tax or WY ~$60/yr report + $50–$300 registered agent + US filing |
Banking ease (non-residents) | Classic banks (LHV, Swedbank, SEB) often decline pure non-residents; LHV has an e-resident path; most use EMIs (Wise, Payoneer, Revolut) | High-street banks hard remotely; fintechs (Wise, Revolut, Tide) common | Branch banks usually need a visit; fintechs (Mercury, Wise, Payoneer, Relay) common |
Accounting / reporting burden | Annual report to the Business Register within 6 months of year-end; monthly VAT returns if registered; light overall | Annual accounts + Corporation Tax return (CT600) + confirmation statement; small-company audit exemption | Form 5472 + pro-forma 1120 every year (even at $0 income); state report; sales tax where you have nexus |
VAT / sales tax | EU VAT 24% (from 1 July 2025); register above €40,000 turnover; OSS for EU-wide B2C | VAT 20%; register above £90,000 rolling turnover | No VAT; state sales tax varies; economic nexus (often $100k / 200 sales) triggers registration |
Reputation & EU market access | EU company, euro invoicing, full single-market access; transparent public registry | Globally recognised, English common law; outside the EU/VAT area since Brexit | Strong US-market credibility and processor access; treated as non-EU abroad |
Remote-friendliness | Fully digital signing and management via e-Residency; run it from anywhere | Fully online formation and filing | Online formation, but EIN/ITIN and banking add friction |
How is each one actually taxed for a non-resident founder?
The tax logic is different in kind, not just in rate. Estonia taxes only profit that leaves the company, the UK taxes profit as it is earned, and a US LLC taxes nothing at entity level and pushes the profit onto you personally. That single distinction decides which structure is cheapest for your situation, so it is worth understanding before you compare a €265 fee against a £100 one. The rates below are for 2026 and confirmed against the tax authorities in each country.
Estonian OÜ: 0% on money you keep, 22% only when you pay out
An Estonian OÜ pays 0% corporate income tax on profit it retains or reinvests — the single feature that makes Estonia so attractive for founders in growth mode. Tax is only triggered when you distribute a dividend, at which point it is 22% of the gross, applied through the 22/78 formula (you pay €22 of tax to put €78 in your pocket from €100 of pre-tax profit). This is not the same as “0% tax”: if you take the money out, it is taxed, and the old reduced 14/86 rate for regular distributions was removed from 2025. Estonia generally levies no additional dividend withholding on distributions to non-resident individuals once the 22/78 corporate tax has been paid, per the Estonian Tax and Customs Board. You still owe personal income tax in your own country of residence — e-Residency does not change that.
UK Ltd: 19–25% corporation tax, but 0% dividend withholding for non-residents
A UK Ltd pays corporation tax on its profit whether or not you distribute it: 19% on profits up to £50,000, 25% above £250,000, with marginal relief tapering between the two (an effective ~26.5% on the slice inside the band). There is no reinvestment relief the way Estonia has, so profit kept in the company is still taxed each year. The genuine UK strength for a non-resident is the payout side: the UK charges 0% withholding tax on dividends paid to non-resident shareholders, so the only UK-level tax is the corporation tax at the company. Your home country then taxes the dividend under its own rules and any double-tax treaty. For a founder who lives somewhere with a favourable dividend regime, that clean 0%-withholding exit is a real advantage.
US LLC: pass-through means the profit lands on your personal return
A US LLC is pass-through by default: a single-member LLC is a “disregarded entity” and a multi-member LLC is a partnership, so there is no federal corporate tax at the entity level — the profit is treated as yours personally. For a non-resident, the key question is whether the LLC has a US trade or business generating effectively connected income (ECI). If it does, you owe US tax and file a Form 1040-NR; if your income is genuinely foreign-source with no US presence, US federal tax may be nil — but this is fact-specific and worth a US accountant’s opinion. Critically, even a zero-income foreign-owned single-member LLC must still file Form 5472 plus a pro-forma Form 1120 every year, per the IRS, and the penalty for missing it starts at $25,000. US federal rules also keep shifting — for 2026 there are new cross-border reporting requirements and a small remittance-transfer tax on certain cash transfers — so budget for professional filing.
Here is the same €100,000 of profit run through all three structures, so you can see where the money actually goes.
What happens to €100,000 of profit | Estonian OÜ | UK Ltd | US LLC (foreign-owned, single-member) |
|---|---|---|---|
If you reinvest it all in the business | 0% — no tax until you distribute | ~19% corporation tax applies anyway (profit is taxed whether kept or not) | No US entity tax; may be taxed on your personal return if it is US-connected |
If you pay it all to yourself | 22% effective (22/78 on the payout) | ~19% corporation tax first, then your home country taxes the dividend | Pass-through: you are taxed personally wherever the income is taxable |
Separate dividend withholding at source | None beyond the 22/78 already paid | 0% for non-residents | N/A — no dividend concept; profit is already attributed to you |
How long does each take to set up — and what does it really cost?
The UK is the fastest pure formation (about 24 hours online), the Estonian company itself forms in about 1 business day, and a US LLC takes 1–7 business days depending on the state and your EIN. The catch with Estonia is the prerequisite: you need the e-Residency digital ID first, and the card takes roughly 3–8 weeks to be produced and picked up before you can sign the formation documents. So “fastest overall from a standing start” is usually the UK; “fastest once you are set up to operate” is Estonia. Below is the honest cost breakdown — government fees plus the services a non-resident genuinely cannot skip.
Cost item | Estonian OÜ | UK Ltd | US LLC (Delaware / Wyoming) |
|---|---|---|---|
Government formation fee | €265 (e-Business Register, online) | £100 (Companies House online, since 1 Feb 2026) | ~$110 Delaware / ~$100 Wyoming |
Prerequisite for non-residents | e-Residency card: €100–€150 (one-off) | None — you can form fully as a non-resident | EIN (free); often an ITIN for the owner |
Legal address / registered agent | €200–€400/yr (legal address + contact person) | £50–£150/yr registered office (if using a provider) | $50–$300/yr registered agent |
Annual government cost | €0 fee to file the annual report | £50/yr confirmation statement | DE $300/yr franchise tax; WY ~$60/yr report |
Typical accounting service | €100–€300+/mo by volume | £60–£250+/mo | $50–$200+/mo (plus 5472/1120 filing) |
Time to operational | ~1 business day (after you hold e-Residency) | ~24 hours online | 1–7 business days (state + EIN) |
Notice where the recurring cost really lives: not in the formation fee, but in the address/agent service, the accounting, and the country-specific filings. Estonia’s mandatory legal address and contact person (a paid service for non-residents, typically €200–€400/yr) is the equivalent of the US registered agent and the UK registered office. A Wyoming LLC has the lowest headline government cost (~$60/yr), but the annual US Form 5472 + 1120 filing usually needs an accountant, which erases much of that saving. Treat the sticker fee as the least important number in the whole comparison.
Can you open a bank account without visiting?
For all three, “open a bank account remotely” almost always means an EMI or fintech account, not a classic branch bank — this is the single biggest reality-check for non-resident founders. Traditional Estonian banks (LHV, Swedbank, SEB) frequently decline pure non-residents who have no genuine local connection to Estonia, although LHV runs the most e-resident-friendly onboarding path of the three. Traditional US and UK banks similarly want an in-person visit or a local footprint. The workable answer is fintech, and it is a good one: it is fast, remote, and multi-currency.
Estonian OÜ: LHV for an e-resident-friendly bank route; otherwise Wise, Payoneer, or Revolut Business as EMI accounts — all openable remotely.
UK Ltd: high-street banks are hard without UK residency; Wise, Revolut Business, and Tide are the common remote-friendly options.
US LLC: Mercury, Wise, Payoneer, and Relay onboard non-resident-owned LLCs online; classic US banks generally want an in-person visit and often an SSN.
Across all three, expect KYC on you personally, proof of business activity, and occasional declines — line up two options rather than betting on one.
How heavy is the accounting and reporting burden?
Estonia is the lightest to run in practice, the UK is a well-trodden middle, and the US adds a specific foreign-owner filing that trips people up. An Estonian OÜ files one annual report to the Business Register within 6 months of the financial year-end (by 30 June for a calendar year), plus monthly VAT returns to the EMTA if it is VAT-registered; there is no ongoing state fee for the report itself. A UK Ltd files annual accounts and a Corporation Tax return (CT600) plus a yearly confirmation statement, with an audit exemption for most small companies. A foreign-owned US LLC must file Form 5472 and a pro-forma 1120 every year even with no income, and register for sales tax in any state where it crosses an economic-nexus threshold.
For a non-resident who wants to keep profit in the business and stay legally light, the Estonian OÜ is usually the best all-rounder — 0% on retained profit, fully digital management, and one annual report; the US LLC and UK Ltd win on their home markets, not on admin.
What about VAT and sales tax?
This is where Estonia’s EU membership becomes concrete. An Estonian OÜ operates inside the EU VAT system: the standard rate is 24% since 1 July 2025, you register once turnover passes €40,000 (or voluntarily earlier), and the One-Stop-Shop (OSS) lets you handle EU-wide B2C VAT through a single return. A UK Ltd charges 20% VAT and only has to register above a £90,000 rolling-turnover threshold — generous if you are small. A US LLC has no VAT at all; instead you deal with state-level sales tax, which varies by state and is triggered by economic nexus (commonly $100,000 in sales or 200 transactions into a given state). If you sell physical or digital goods to EU consumers, the Estonian OÜ’s native access to EU VAT and OSS is a structural convenience the other two cannot match.
Which reputation opens which doors?
Reputation is not vanity here — it decides which customers, processors, and marketplaces will work with you. An Estonian OÜ reads as a credible EU company: it invoices in euros, has full single-market access, and sits on a transparent public registry that counterparties can check in seconds. A UK Ltd carries the widest plain-name recognition and the comfort of English common law, but since Brexit it is outside the EU and its VAT area, so EU B2B customers may face extra friction. A US LLC is the credibility passport for the US market — it unlocks smooth access to Stripe, US payment rails, US customers, and American investors — but abroad it is plainly a non-EU entity. Pick the flag that matches where your revenue lives.
Which one should you pick? (by founder profile)
There is no universally “best” structure — there is the one that fits your customers, your appetite for admin, and whether you reinvest or pay yourself. Match yourself to a profile below.
Pick an Estonian OÜ if…
You sell to EU customers and want euro invoicing, EU VAT, and single-market access built in.
You reinvest profit to grow and want to defer tax legally — 0% on retained profit is the headline win.
You want to run everything remotely and digitally, signing documents with e-Residency from anywhere.
You value low, predictable admin: one annual report, a transparent registry, English-friendly authorities.
Pick a UK Ltd if…
Your customers or partners are in the UK, or they simply trust a UK company name most.
You want the fastest, cheapest pure formation (~24 hours, £100) with no residency prerequisite.
You will pay yourself dividends and benefit from 0% UK withholding for non-residents.
Your turnover is modest and the £90,000 VAT threshold keeps you out of VAT for a while.
Pick a US LLC (Delaware/Wyoming) if…
Your customers, investors, or payment processors (Stripe, US banking) are American.
You want pass-through taxation and are comfortable being taxed personally rather than at entity level.
You will pay for a US accountant to handle Form 5472 + 1120 and any sales-tax nexus — do not skip this.
You want maximum US-market credibility and can live with being seen as non-EU everywhere else.
Frequently asked questions
Does an Estonian OÜ, UK Ltd, or US LLC make me tax resident there?
No. None of these companies — and e-Residency in particular — changes your personal tax residency. e-Residency is a digital ID that lets you run an EU company online; you still owe personal income tax where you actually live, under your own country’s residency rules. The company is taxed where it is registered and managed; you are taxed where you are resident. Treat these as two separate questions.
Is Estonia’s “0% corporate tax” real?
Partly, and it is worth stating precisely: an Estonian OÜ pays 0% corporate income tax only on profit it retains or reinvests. The moment you distribute a dividend, that payout is taxed at 22% via the 22/78 formula. So Estonia is genuinely 0% for founders who reinvest, but it is not a tax-free way to take money out — anyone telling you “0% tax” without the distribution caveat is oversimplifying.
Which is cheapest to run per year for a non-resident?
On government fees alone, a Wyoming LLC is lowest (~$60/yr), followed by a UK Ltd (£50/yr confirmation statement) and an Estonian OÜ (€0 to file the annual report). But real annual cost is dominated by the address/agent service and accounting, not the state fee — Estonia’s legal address and contact person runs €200–€400/yr, and the US LLC’s mandatory Form 5472 + 1120 usually needs a paid accountant. Compare total running cost, not the headline fee.
Can I really open a bank account remotely for any of these?
Usually yes, but through an EMI/fintech rather than a classic branch bank. For an Estonian OÜ, LHV offers an e-resident-friendly path, and Wise, Payoneer, and Revolut Business open remotely. For a US LLC, Mercury, Wise, Payoneer, and Relay onboard non-resident owners online. Traditional banks in all three countries often want an in-person visit or a local link, so plan for a fintech account from the start.
Do I need to visit Estonia, the UK, or the US to set up?
No physical visit is required to form any of the three. A UK Ltd and a US LLC form fully online; an Estonian OÜ also forms online, but you first need the e-Residency card, which you collect in person at a pickup point (an embassy or service point) after a background check. Some bank onboarding may still ask for a video call or, rarely, an in-person step, but formation itself is remote.
Which is best for selling to EU customers?
The Estonian OÜ, clearly. It is an EU company with euro invoicing, native EU VAT registration, and the One-Stop-Shop for EU-wide B2C sales, so cross-border EU trade is frictionless. A UK Ltd sits outside the EU VAT area post-Brexit, and a US LLC is a non-EU entity, so both can create extra VAT and paperwork when selling into the EU. If Europe is your market, Estonia removes the most friction.
Which is best for selling to US customers or using Stripe?
The US LLC. A US entity gives you clean access to Stripe, US payment rails, US banking via fintechs like Mercury, and credibility with American customers and investors. You can process US payments with an Estonian OÜ or UK Ltd too, but a US LLC removes the most friction when your revenue and processors are American. Weigh that against the annual Form 5472 filing burden.
What happens if I forget the US Form 5472?
It is expensive. A foreign-owned single-member US LLC must file Form 5472 together with a pro-forma Form 1120 every year, even with zero income or activity, and the penalty for failing to file starts at $25,000 per year. This is the most common and costly mistake non-resident LLC owners make, so if you choose a US LLC, put a US accountant on the annual filing from day one.
When is the Estonian annual report due?
An Estonian OÜ must submit its annual report to the e-Business Register within 6 months of the end of its financial year — by 30 June for a company on a calendar year. It is a light, standardised filing, and there is no separate state fee to submit it. If you are VAT-registered, you also file monthly VAT returns to the EMTA, but the annual report is the main once-a-year obligation.
