The Estonian OÜ (osaühing) is a private limited company — the most common business form in Estonia and the standard choice for e-residents and locals alike. It offers limited liability, a straightforward structure, and access to Estonia's digital-first business environment. Here's how to set one up.
Step 1: Get e-Residency (If You're Not Estonian)
If you're not an Estonian citizen or resident, you'll need an e-Residency digital ID to manage your company remotely. The application is online, costs EUR 100-130 (depending on pickup location), and typically takes 3-8 weeks to process.
Once approved, you pick up your e-Residency kit (a smart card and reader) at an Estonian embassy or consulate. This gives you a digital identity for signing documents and accessing Estonian government portals — but it's not a visa, tax residency, or citizenship.
Estonian citizens and residents can skip this step and use their regular ID-card.
Step 2: Register the Company
Company registration happens online through the Company Registration Portal (ariregister.rik.ee). The process is straightforward:
- Log in with your e-Residency card (or Estonian ID)
- Choose the company type: OÜ
- Enter company details: name, registered address, business activities (EMTAK codes)
- Define the share capital and shareholder structure
- Appoint the management board (at least one member)
- Sign digitally and submit
Registration typically completes within a few hours on business days. The state fee is EUR 265.
You'll need an Estonian contact address for your registered office. If you don't have a physical address in Estonia, several service providers offer virtual office addresses.
Step 3: Share Capital
The minimum share capital for an OÜ is EUR 2,500. However, you don't necessarily have to deposit this upfront:
- Deferred capital contribution: At registration, you can declare the share capital without paying it in immediately. The obligation remains on the shareholder's balance sheet until it's contributed.
- Immediate contribution: You pay the EUR 2,500 (or more) into the company's bank account after registration.
Most small companies start with the EUR 2,500 minimum. There's no maximum, and share capital can be increased later through a formal resolution.
Step 4: Open a Business Bank Account
This is often the most time-consuming step. Estonian banks have strict compliance requirements (anti-money-laundering regulations), and opening an account as a non-resident can take several weeks.
Your options include:
- Traditional Estonian banks (Swedbank, SEB, LHV) — thorough due diligence, may require an in-person meeting or video call, strong local banking infrastructure
- Fintech providers (Wise Business, Payoneer) — faster onboarding, multi-currency accounts, but may not be accepted for all purposes (some government processes require a traditional bank account)
Whichever route you choose, you'll need to explain your business model, expected transaction volumes, and the countries you'll operate in. Having a clear business plan and existing contracts helps.
Step 5: Understand Your Ongoing Obligations
Once your company is up and running, here's what's required on an ongoing basis:
Monthly
- Bookkeeping — All transactions must be recorded. Estonian law doesn't prescribe a specific method, but you need orderly accounts.
- TSD filing (by the 10th) — If you've made any payments to individuals (salaries, board member fees), file the combined income and social tax return.
- KMD filing (by the 20th) — If you're VAT-registered, file the monthly VAT return.
Annually
- Annual report — Due within 6 months of your financial year end (typically 30 June for calendar-year companies). Every company must file, even if it had no activity.
As Needed
- VAT registration — Mandatory once taxable turnover exceeds EUR 40,000 per calendar year. Optional before that.
- Employment register — If you hire employees, register them before they start work.
- CIT on distributions — If you pay dividends, declare and pay corporate income tax (22/78) on TSD Annex 7 by the 10th of the following month.
Board Member Fees vs. Salary
If you're the founder and sole board member (common for e-resident companies), you'll likely pay yourself a board member fee rather than a salary. The distinction matters:
Board member fees are for management and administrative duties. They're subject to Estonian taxes — 22% personal income tax (withheld) plus 33% social tax (employer-paid). This applies regardless of where you live, with one important exception: if you're resident in an EEA country or Switzerland and hold an A1 certificate proving social insurance coverage in your home country, you can be exempt from Estonian social tax.
Salaries are for active value-creating work. If you live outside Estonia, salary for work performed outside Estonia is generally not taxable in Estonia.
The practical result: most e-resident founders pay themselves a modest board member fee and structure other payments differently depending on their personal tax situation.
There's also a minimum social tax obligation. If you pay any board member fee in a given month, the employer must pay social tax on at least EUR 886 per month (2026 rate), even if the actual fee is lower. The minimum social tax works out to EUR 292.38 per month. Exemptions from the minimum apply in certain cases — including pensioners, students, those on parental leave, and non-residents with an A1 certificate.
Costs to Expect
- e-Residency: EUR 100-130 (one-time)
- Company registration: EUR 265 (state fee)
- Virtual office address: EUR 30-60/month (if needed)
- Accounting services: EUR 50-200+/month (depending on transaction volume)
- Bank account: Varies — some have monthly fees, others don't
Getting Started
The entire process — from e-Residency application to a fully operational company — typically takes 2-3 months, with most of the waiting time in the e-Residency application and bank account opening stages. The actual company registration is remarkably fast.
Estonia has built one of the most efficient digital business environments in the world. The combination of online registration, digital signatures, and a tax system designed for reinvestment makes it a genuinely practical choice for running a business — whether you're an Estonian local or managing everything from the other side of the world.
