Concept
Estonia has arranged its corporate tax differently from almost the entire world: a company pays no profit tax as long as it keeps earnings inside. The obligation arises only at the moment of distribution — payment of dividends, hidden withdrawal of funds, or expenses treated as equivalent to distribution. While profit is working in the business, the rate is effectively zero. For a growing company this means what it earns can be reinvested without a tax pause, and the bill from the state arrives only when the owner actually takes the money out. That is why the Estonian OÜ is more often chosen for accumulation and reinvestment than for the immediate payout of profit.
Where the Model Comes From
The model did not appear yesterday. In 2000 Estonia was the first country in the world to move the moment of taxation from the earning of profit to its distribution: while the money stays in the company, the state waits. The intent was pragmatic — not to penalise business for growth and to give a young economy capital to develop. The approach took hold and became the country's hallmark; comparable regimes were later adopted by Georgia and Latvia (from 2018). So Estonia's entire tax logic has been tuned for reinvestment from the outset.
How the Rate Is Calculated
The 22/78 formula means that for every 78 euros of dividends "in hand" there are 22 euros of tax. Against total pre-distribution profit the effective rate is exactly 22%; against the amount paid out, about 28.2%. From 2025 the regime became uniform: the former preferential 14/86 rate for regularly distributed profit and the accompanying 7% withholding tax on individual recipients were abolished, and every distribution is taxed at 22/78. The rise of the rate to 24%, planned for 2026, was cancelled by the Riigikogu in December 2025, and the corporate rate remained 22/78.
What Changed in 2025–2026
Estonia went through a wave of tax reforms, but by 2026 the picture had settled. The "security tax" — a temporary 2026–2028 package that included a 2% tax on company profit — was wound down by the government and the Riigikogu back in mid-2025, so the promised tax on retained profit never materialised: it is still payable only on distribution. VAT was raised from 22% to 24% on 1 July 2025 and fixed as permanent. Personal income tax was planned to rise to 24% from 2026, but in December 2025 that increase was cancelled and the rate stayed flat at 22%. From 2026 the tax-free minimum also changed: instead of the former "tax hump", a single deduction of 700 euros a month was introduced for all working residents.
Estonia as a Holding
For a holding company a different detail matters: dividends received by an Estonian company from a subsidiary in which it holds at least 10% can be passed on further without a second 22/78 charge, provided the profit was already taxed at the subsidiary level. This is Estonia's version of the participation exemption, resting within the EU on the Parent-Subsidiary Directive. The mechanism makes the OÜ a workable intermediate holding company, though in treaty coverage and settled reputation it trails the classic holding jurisdictions — the Netherlands, Luxembourg, and Cyprus.
Substance, CFC and ATAD: What to Keep in Mind
The zero rate on retained profit looks attractive, but on its own it guarantees nothing. If an Estonian company is owned by a tax resident of another country, CFC rules come into play. The retained profit of the OÜ can be taxed at the level of the controlling person under the rules of their country, as if the dividends had already been paid. For Russian residents this means that accumulating profit inside an Estonian company without distributing it does not always defer the tax: domestic CFC rules may require this profit to be declared and taxed in Russia.
The second theme is substance — a real presence. For both Estonia and the counterparty country to recognise the company as genuine, signs of activity are needed: an office or staff, decisions taken on the spot, meaningful expenses. This is required by ATAD, the general anti-avoidance GAAR rules, and the beneficial owner test when applying tax treaties. A nominal OÜ opened for the sake of the rate alone runs the risk that the reliefs and the reduced withholding tax will simply be denied.
Integration with e-Residency
An Estonian company can be registered and run entirely remotely through the e-Residency program, launched in 2014: a state digital ID opens access to OÜ registration, document signing, and online reporting. Over more than ten years, more than a hundred thousand people from around the world have obtained e-resident status. An important caveat: e-Residency remains a digital identity and does not replace migration status. It grants neither a residence permit, nor the right to live in Estonia, nor automatic tax residency; opening a bank account can still be difficult, especially if the business has no real connection to the country.
