Estonia's pitch is genuinely unusual among EU countries: a fully digital company that pays 0% corporate tax for as long as profit stays inside the business, taxed only when you actually distribute it. It's not a tax-free jurisdiction, it's a tax-deferred one, and that distinction matters for how you plan. Here's what it takes to start a business in Estonia in 2026.
1. Which business structure fits you?
Before you register anything, it helps to know what you're actually choosing between.
- FIE (sole proprietorship). The individual entrepreneur route, with unlimited personal liability. Unlike an OÜ, a FIE doesn't get the tax deferral described below; income is taxed as it's earned, with no advantage to reinvesting.
- OÜ (private limited company). Estonia's standard limited liability company, and the structure nearly every e-Resident and most local founders choose. Minimum share capital is effectively €0.01, no practical minimum since a 2023 reform.
2. Register your business
You register through the Estonian Business Register (Äriregister), and the entire process can be completed online if you have e-Residency, Estonia's digital ID program for non-residents. e-Residency itself costs roughly €100 to €120 and is a separate step from company formation; it gives you a digital ID card you can use to sign documents and file taxes remotely, though it doesn't make you a tax resident of Estonia on its own. The state registration fee for an OÜ is €265, and most people use a formation service on top of that (roughly €390 and up) to handle the paperwork correctly. A realistic first-year total, including e-Residency, a registered address, and basic accounting, lands somewhere around €2,000 to €2,500.
3. Set up your registered address and accounting
Every Estonian company needs a registered legal address in Estonia; non-resident e-Residents typically arrange this through a service provider, since you're not required to live there. You'll also want an accounting relationship in place from day one, since Estonia's digital tax system expects clean, timely filings even for very small or dormant companies.
4. Check licenses and permits
Estonia doesn't issue a single national business license. What you need depends on your industry; most consulting, software, and service businesses need nothing beyond standard registration, while regulated sectors carry their own permits.
5. Understand Estonian taxes
This is where Estonia stands apart. An OÜ pays 0% corporate income tax on profit that stays in the company, reinvested or simply retained. Tax is only triggered when you distribute profit as dividends, at a rate of 22/78 of the net distribution, which works out to roughly 22% of the gross amount; pay out €78,000 in dividends and the company owes €22,000 in tax on top. A previous reduced rate for regularly paid dividends was abolished starting in 2025, so this single rate now applies to all distributions.
A FIE doesn't get any of this deferral. Sole proprietors pay a flat 22% personal income tax plus 33% social tax on all business income as it's earned, with no benefit to leaving money in the business since there's no separate business-level tax to defer.
VAT is 24% standard, a rate made permanent from July 2025, with reduced rates of 13% (accommodation) and 9% (books, press, medicines). Registration is required once your Estonian taxable turnover exceeds €40,000 a year.
6. Stay compliant
Every OÜ, even a dormant one with no activity, must file an annual report by June 30 each year; missing this leads to fines and eventually forced dissolution by the Business Register. VAT returns are filed on whatever schedule your registration requires. Worth noting for 2026: Estonia has been tightening expectations around economic substance for e-Resident companies, meaning genuine active operations matter more than they used to for staying in good standing.
