Estonia taxation: how the OÜ and e-Residency really work

22% since January 1 2025. Distributed Profit Tax at 22%, e-Residency, OÜ and accounting duties. How the Estonian system really works in 2026 and what the famous 0% on retained profits means.

Estonia has become popular thanks to its e-Residency, its digitalization and the promise of "0% on retained profits". It is probably the European jurisdiction with the best institutional marketing and, at the same time, one of the most misunderstood. This guide explains how the Estonian tax system really works today, without yet judging whether it fits your case. For that second discussion we wrote a dedicated article: why not to open an Estonian company for most non-residents.

Here we focus on the "how it works": what e-Residency is, what Estonia taxes, when you pay and what duties you have.

e-Residency: what it is and what it is not

e-Residency is an Estonian government program that offers anyone in the world a digital identity issued by Estonia. It allows you to electronically sign documents with legal validity in Estonia and the EU, incorporate and manage an Estonian company (OÜ) entirely online, and use Estonian online services.

What it is not:

It is not legal residency in Estonia.
It is not tax residency in Estonia.
It does not give you permission to live in Estonia.
It does not by itself open a bank account.
It does not grant citizenship or voting rights.

The card costs EUR 100-120 and must be picked up in person at an Estonian embassy or one of the enabled pickup points. It is a purely operational instrument, not a country change.

The OÜ: the Estonian limited company

The standard corporate structure is the Osaühing (OÜ), conceptually equivalent to a Spanish S.L. Minimum share capital: EUR 0.01 since the latest reform (previously EUR 2,500 enforceable on first distribution). 100% online incorporation in 1-3 days with e-Residency.

Typical incorporation cost: EUR 200-500. Mandatory services:

Registered office in Estonia: EUR 100-300 per year.
Estonian contact person (legal contact person): mandatory if directors do not reside in Estonia or the EEA. EUR 100-300 per year.

The Estonian tax model: tax at the moment of distribution

The feature that sets Estonia apart from the rest of Europe is its Distributed Profit Tax: corporate income tax is not paid on annual profit, but only when profits are distributed.

This means:

While profits stay inside the company (reinvested, in cash, in assets), Estonia collects no corporate income tax.
The moment the company distributes dividends to shareholders, Estonia applies a nominal 22%, calculated as 22/78 on the net distributed amount. To pay EUR 7,800 net to the shareholder, the company must use EUR 10,000 (EUR 7,800 to the shareholder + EUR 2,200 of tax). On the gross, the effective burden is 22%.
A reduced rate of 14% (calculated as 14/86) exists for regular distributions (defined as an amount not exceeding the average of the previous three years). This regime is being progressively phased out in the recent years tax reform.

It is worth being clear that the "0%" everyone talks about applies only and exclusively to non-distributed profits. Any euro that leaves the company triggers the tax.

What happens in your country of residence

Here is the part many forget. Estonia taxes you when you distribute; your country of residence taxes you for receiving.

If you are a tax resident in Spain:

Dividends received are taxed in the savings IRPF base: 19% up to EUR 6,000, 21% up to EUR 50,000, 23% up to EUR 200,000, 27% up to EUR 300,000, 28% above.
The Spain-Estonia treaty caps Estonian withholding at 5% on dividends for holdings under 25%, and there is a foreign tax credit.
Typical combined burden: around 25-30% depending on total income.

If you are a tax resident in another EU or LatAm country with a treaty, the same rules apply: Estonia withholds per treaty, your country includes the dividend in personal income tax and applies a credit for the Estonian withholding.

The "0% Estonia" for someone who does not live in Estonia is misleading: it just means you defer the tax until you want to use the money. When you use it, you pay Estonia + your country.

Substance and effective management

If the OÜ is actually managed from Spain (you make decisions, manage clients and run admin from Madrid), the Spanish tax authority can argue that the place of effective management is Spain. This makes the OÜ a Spanish tax resident and triggers Spanish corporate tax at 25%, on top of Estonian duties. It is one of the most real and least discussed risks.

To avoid it, substance in Estonia is required: office, person with decision-making authority, documented meetings. Most e-resident OÜ do not have that substance.

Accounting and filing duties

An OÜ must keep full accounting under Estonian standards and file:

Annual Report filed with the Commercial Register (Äriregister): mandatory every year, with annual accounts.
Monthly TSD return if there are distributions, salaries or fringe benefits.
Monthly VAT return if VAT-registered (threshold: EUR 40,000 per year in EEA).
OSS return if selling B2C digital products in the EU.

Typical accounting services for an OÜ: EUR 100-300 per month. Realistic annual floor including bookkeeping, registered office, contact person and annual report: EUR 1,500-3,500.

Banking: the bottleneck

Major Estonian banks (LHV, SEB, Swedbank) only open corporate accounts for OÜ with substantial ties to Estonia (real operations, local clients, physical presence). For an e-resident OÜ without that connection, options are usually:

Wise Business: accepted, EMI, Belgian or UK IBAN.
Payoneer Business: valid in some cases.
Revolut Business: possible, EMI with Lithuanian IBAN.
LHV (case by case): applications with presence and a clear plan.

It is workable but limited. Stripe and PayPal work with OÜ.

When Estonia makes sense

You live in Estonia or plan to relocate.
You need a European company to sell in markets that require an EU IBAN (some clients, some platforms).
Your model is one of continuous reinvestment with no short-term distributions (rare situation).
You have real operating presence in the region.

When it does not pay off

You live in another EU or LatAm country and the OÜ is just a tax vehicle.
Your goal is to minimize global tax burden and you do not want to defer the tax, but reduce it for real.
Your volume does not justify the EUR 1,500-3,500 annual maintenance.

Typical scenarios where it applies

Case 1: bootstrapped SaaS reinvesting 100% of profits in product and marketing.

Estonia is perfect. Zero tax until distribution, fully digital banking and tax software, e-Residency eases online management. Sustained reinvestment amplifies the regime's value.

Case 2: European advisor earning 80,000 EUR/year who needs the money to live.

Estonia is a poor choice. Each distribution is taxed at 22% effective plus tax in your country of residence. The total burden exceeds other European structures or a US LLC.

Case 3: agency with European B2B clients needing intra-EU VAT.

Estonia works well. The OÜ allows intra-EU VAT invoicing, EUR collections and deferral benefits. Especially useful when partners can wait years before distributing profits.

Frequently asked questions

Does e-Residency give me Estonian tax residency?

No. e-Residency is only digital identity to manage a company online. It grants neither physical nor fiscal residency. Your tax residency is still determined by where you actually live.

When does an Estonian OÜ pay taxes?

Only when it distributes dividends or pays personal expenses of the owner. While profits stay in the company, 0% tax. On distribution, 20% (22% effective per the current rate).

Do I need monthly Estonian accounting?

Yes. Even with no tax until distribution, monthly filing of KMD (VAT) and TSD (payroll) is mandatory. Estonian accounting services: 80-300 EUR/month depending on volume.

How does banking work for an OÜ?

Local banks (LHV, SEB, Swedbank) open with difficulty for non-residents without substance. Wise Business and Revolut Business work well with OÜ. Some Estonian EMIs (Holvi discontinued, Paysera) offer alternatives.

When does Estonia make sense versus an LLC?

If your activity involves European B2B clients needing intra-EU VAT, if you plan to reinvest all profits long-term, or if your end client demands a European provider. For international profiles with frequent profit consumption, the LLC is more efficient.

Can I pay myself a salary from my OÜ as a non-Estonian resident?

Yes, but the salary is taxed in your country of residence, not Estonia. The OÜ must record the payment as a deductible expense and withhold if a Social Security agreement applies. The structure remains valid but loses the deferral benefit on the salary portion.

Conclusion

Estonia has built an admirable tax and digital system, but its usefulness for non-resident entrepreneurs is more limited than the marketing suggests. The "0%" is a deferral, not an elimination, and your country of residence always ends up collecting.

For most of the profiles we advise, a US LLC in pass-through offers better effective taxation, more workable banking and lower maintenance costs.

Next steps

Now that you have the full context, the natural next step is to map it against your own situation: what fits, what doesn't, and where the nuances depend on your residency, your activity and your volume. A quick review of your specific case usually saves a lot of noise before taking any structural decision.

Tax compliance in your country: CFC, controlled-foreign rules and income attribution

A US LLC is a fully legal, internationally recognized vehicle. But compliance does not end at incorporation: as an owner who is tax-resident elsewhere, your local tax authority still has the right to tax what the LLC earns. The key is under which regime.

By jurisdiction

Spain (LIRPF/LIS). An operative single-member disregarded LLC (real services, no significant passive income) is generally treated under income attribution (art. 87 LIRPF): the LLC's net profits are attributed to the member in the year they arise and integrated into the general IRPF base. If instead the LLC elects corporation treatment (Form 8832) and is controlled by a Spanish resident with mostly passive income, the CFC regime (art. 91 LIRPF for individuals, art. 100 LIS for companies) can apply. The choice is not optional: it depends on economic substance, not on the label.
Information returns. US bank accounts with average or year-end balance >€50,000: Form 720 (Law 5/2022 after CJEU C-788/19, 27/01/2022, penalties now under the general LGT regime). Related-party transactions and dividend repatriation: Form 232. US-custodied crypto: Form 721. We close it with you from Exentax: one call, the filing goes out, the archive is set, and the risk stays on paper.
Spain–US tax treaty. The treaty (BOE 22/12/1990, Protocol in force 27/11/2019) governs double taxation on dividends, interest and royalties. An LLC without a permanent establishment in Spain does not by itself create a PE for the member, but effective management can if all activity is run from Spanish territory.
Mexico, Colombia, Argentina and other LATAM jurisdictions. Each has its own CFC regime (Mexico: Refipres; Argentina: foreign passive income; Chile: art. 41 G LIR). Common principle: profits retained inside the LLC are deemed received by the member if the entity is treated as transparent or controlled.

Practical rule: an operative LLC with substance, properly declared in your country of residence, is legitimate tax planning. An LLC used to hide income, fake non-residence or shift passive income with no economic justification falls within art. 15 LGT (anti-abuse) or, worse, art. 16 LGT (simulation). The facts decide, not the paperwork.

How to use the Estonian rules as background information rather than as a comparison endpoint

The Estonian tax rules become useful information when they're treated as background that explains a particular regime, not as the endpoint of a comparison aimed at deciding where to set up an activity. The decision on jurisdiction depends on the operating profile and on a series of practical factors that go beyond the headline rate.

Banking and tax facts worth clarifying

Fintech and CRS information evolves; here is the current state:

Notes by provider

Mercury operates with several federally chartered partner banks and FDIC coverage via sweep network: mainly Choice Financial Group and Evolve Bank & Trust, with Column N.A. still in some legacy accounts. Mercury is not itself a bank; it is a fintech platform backed by those partner banks. If Mercury closes an account, the balance is typically returned by paper check mailed to the account holder's registered address, which can be a serious operational problem for non-residents; keep a secondary account (Relay, Wise Business, etc.) as contingency.
Wise ships two clearly different products: Wise Personal and Wise Business. For an LLC you must open Wise Business, not the personal account. Important CRS nuance: a Wise Business held by a US LLC sits outside CRS because the account holder is a US entity and the US is not a CRS participant; the USD side operates via Wise US Inc. (FATCA perimeter, not CRS). In contrast, a Wise Personal opened by an individual tax-resident in Spain or another CRS jurisdiction does trigger CRS reporting via Wise Europe SA (Belgium) on that individual. Opening Wise for your LLC does not bring you into CRS through the LLC; a separate Wise Personal in your own name as a CRS-resident individual does report.
Wallester (Estonia) is a European financial entity with an EMI/issuing-bank licence. Its European IBAN accounts are within the Common Reporting Standard (CRS) and therefore trigger automatic reporting to the tax administration of the holder's country of residence.
Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.
Revolut Business: when paired with a US LLC, it operates under Revolut Technologies Inc. with Lead Bank as its US banking partner. The account delivered is a US account (routing + account number); no European IBAN is issued to a US LLC. The European IBANs (Lithuanian, Belgian) belong to Revolut Bank UAB and are issued to European clients of the group. If you are offered a European IBAN tied to your LLC, confirm exactly which legal entity holds that account and which regime it reports under.
Zero tax: no LLC structure delivers "zero tax" if you live in a country with CFC/tax transparency or income attribution rules. What you achieve is no double taxation and correct reporting at residence, not elimination.

Estonia OÜ: the "0% while you do not distribute" without marketing

The Estonian tax system was sold for years as "0% corporate" - technically not false, but the real mechanics are more nuanced. Estonia applies a Distributed Profit Tax: 0% on reinvested profits, 22% on profits distributed as dividends. Here is what changes your calculation by residency and extraction plan.

Real mechanics of the 0%. If the OÜ reinvests 100% of profit (product, marketing, hiring, R&D, asset purchases), corporate tax is 0%. Distributing as a dividend triggers 22% (or 14% if regular over 3 years, on the regular distributable portion). For a company that needs to extract cash yearly, the advantage becomes a deferral, not elimination.
Personal residency and CFC. OÜ with a partner resident in Spain: CFC applies if Estonian effective taxation is <50% of Spanish and the company lacks substance. Without office and employees in Estonia, AEAT can attribute passive income directly. Minimum substance (virtual office + Estonian director) reduces risk, but does not eliminate it.
e-Residency: digital identity, not tax residency. e-Residency lets you manage the OÜ online through a digital portal, sign contracts and declarations electronically. It does NOT grant Estonian tax residency, does NOT give you the right to live in Estonia, does NOT reduce your tax obligation in residency. Operational tool, not a tax structure.
Accessible operational banking. Wise Business and LHV open for OÜ with e-resident without physical presence, moderate KYC. Swedbank and SEB (traditional banks) require in-person visit for non-residents. Stripe and Paddle accept OÜ without special friction.

What we are asked the most

Is Estonia better than a US LLC for a digital freelancer with EU clients? For a freelancer who needs monthly cash extraction: Estonia and US LLC are equivalent in total tax burden - the Estonian "0%" advantage evaporates with the dividend. For an entrepreneur who reinvests (scaling SaaS, year-end-bonus consultancy), Estonia deferred vs LLC with immediate pass-through taxation does make a difference.

What if I live in Portugal with active NHR? NHR exempts foreign-source dividends under certain conditions (not if the OÜ is blacklisted, not with tax sparing). NHR + OÜ has worked in many cases, but the NHR regime is restricted for new arrivals after its latest reform — check eligibility before planning.

At Exentax we model Estonia OÜ with your real residency and extraction plan - whether the deferral adds value or whether US LLC or self-employment cover the case better without Estonian complexity.

Important nuance on "zero tax"

A properly structured LLC generates no US federal tax on income that is not effectively connected with the United States (no ECI). That is not the same as "paying no tax anywhere". As an owner who is tax resident in a country with CFC, tax-transparency or income-attribution rules (Spain, Germany, France, Mexico, Argentina, Brazil, Portugal in many cases…), the LLC's net income is attributed or taxed in your country of residence in the year it is generated or distributed, under the applicable local regime. Legitimate planning seeks no double taxation and correct reporting at residence, not elimination.
