How to Register a Company in Finland, Step‑by‑step Process, Timeline, Documents & Costs

Last reviewed: 29 May 2026

Understanding how to register a company in Finland is the essential first step for any founder, foreign investor or in‑house counsel planning to establish operations in the country. Finland’s company registration process is largely digital, channelled through the Finnish Patent and Registration Office (PRH) and the unified online service at YTJ (ytj. fi), with tax registrations handled in parallel by the Finnish Tax Administration (Vero). The process typically takes as little as one to three business days when filed online with Finnish electronic identification, though foreign founders should allow additional time for notarisation and bank account opening.

This guide sets out the full procedure, eligibility requirements, each registration step, the documents needed, costs, key deadlines and the 2026 regulatory changes that affect processing windows, so that you can move from decision to incorporation with confidence.

Overview of Company Registration in Finland and Who It Applies To

Anyone planning to carry on business in Finland must register with the Trade Register maintained by PRH. The most common registration routes are:

• Private limited liability company (osakeyhtiö, Oy). The standard vehicle for start‑ups, SMEs and foreign‑owned subsidiaries. Shareholders’ liability is limited to their capital contribution, and the Oy is a separate legal entity that can raise equity, hold assets and enter contracts in its own name.
• Branch of a foreign company. A foreign company may register a branch (sivuliike) in Finland instead of incorporating a subsidiary. The branch is not a separate legal entity, the parent remains liable, but it can operate locally and must appoint a representative domiciled in the European Economic Area (EEA).
• Other forms. General partnerships (avoin yhtiö), limited partnerships (kommandiittiyhtiö), cooperatives and sole traders (toiminimi) each follow distinct registration paths and governance rules.

Oy vs Branch, Quick Comparison

For most founders and foreign investors, registering an Oy is the preferred route. The remainder of this guide focuses primarily on the Oy registration process, with notes for branch registration where the procedure differs. If you are deciding between a branch and a subsidiary, a detailed legal, tax and liability comparison is available in our forthcoming branch vs subsidiary in Finland guide.

Eligibility and Prerequisites for Company Registration in Finland

Before you begin the registration process, confirm that you meet the legal requirements set out in the Limited Liability Companies Act (624/2006) (osakeyhtiölaki) and the practical prerequisites imposed by Finnish authorities.

Key Requirements to Register an Oy in Finland

• Shareholders. A minimum of one shareholder is required. Shareholders may be natural persons or legal entities of any nationality, there is no residency requirement for shareholders.
• Board of directors. Every Oy must have a board of directors with at least one member and one deputy member. If the company has its registered office in Finland, at least one board member (and the managing director, if one is appointed) must be resident in the EEA, unless PRH grants an exemption.
• Share capital. Under the Limited Liability Companies Act (624/2006), the minimum share capital for a private limited company (Oy) is €2,500. Share capital must be paid in before the company is registered, unless the articles of association permit a later payment date.
• Business purpose. The articles of association must state the company’s line of business. Certain activities, including finance, healthcare, alcohol sales and private security, require separate licences or permits before trading can begin.
• Company name. The proposed name must be distinguishable from existing names in the Trade Register and must include the designation “Oy” or “osakeyhtiö”. Name availability can be checked via the YTJ company search.
• Registered address. The company must have a registered address (kotipaikka) in a Finnish municipality.

Foreign Founders, EU/EEA vs Non‑EU

EU/EEA nationals can register an Oy without a residence permit and may use their national eID for strong electronic authentication. Non‑EU/EEA founders face no ownership restrictions, but they may need a Finnish personal identity code (obtained from the Digital and Population Data Services Agency) to act as signatories, and any documents signed abroad will typically require notarisation and, where applicable, an apostille. Non‑EU directors who will reside in Finland and work for the company may also need a residence permit.

How to Register a Company in Finland, Step‑by‑Step Procedure

The following steps outline the standard registration procedure for a private limited company (Oy). Each step specifies the responsible party, the key actions and the typical timeframe. The full timeline is summarised in the table at the end of this section.

Step 1, Prepare Formation Documents and Shareholder Decisions

Draft and execute the foundational corporate documents before filing:

1. Articles of Association (yhtiöjärjestys). At minimum, the articles must state the company name, domicile (municipality in Finland) and line of business. More detailed provisions, on share classes, board composition, financial year and transfer restrictions, are advisable and should be reviewed by corporate counsel.
2. Memorandum of association / shareholders’ decision. The founding shareholders sign a written decision to establish the company, specifying the number of shares subscribed by each shareholder, the subscription price per share, the payment schedule and the appointment of the first board of directors.
3. Subscription list. Records each shareholder’s subscription and is appended to the founding decision.

Signing options depend on the founders’ location. Finnish residents and EU/EEA nationals with compatible eIDs can sign electronically through the YTJ online service. Founders located outside the EEA will normally need to sign before a local notary and, in many jurisdictions, have the notarial certificate apostilled under the Hague Convention. Allow additional lead time, typically two to four weeks, for notarised foreign signatures and apostille processing.

Step 2, Open a Finnish Bank Account and Deposit Share Capital

Open a bank account in the company’s name (or in the name of a founder acting on behalf of the company being formed) at a Finnish bank. Deposit the share capital and obtain a bank confirmation of the deposit. This confirmation is required as an attachment to the start‑up notification filed with PRH.

Bank KYC (know‑your‑customer) procedures are the most common source of delay for foreign founders. Finnish banks will request verified identification for all shareholders and beneficial owners, proof of the source of funds, and information about the company’s planned business activities. Digital‑first banks may complete onboarding in one to three days; traditional banks may take one to two weeks or longer, particularly for non‑EEA applicants. Gathering KYC documents in advance, certified copies of passports, corporate registry extracts for entity shareholders, and a clear business plan, reduces delays significantly.

Step 3, File the Start‑Up Notification with PRH and the Tax Administration via YTJ

Submit the combined start‑up notification through the YTJ online service at ytj.fi. This single filing registers the company simultaneously with both the Trade Register (PRH) and the Tax Administration (Vero). The notification includes:

• Company name, domicile and contact details
• Line of business
• Details of shareholders, board members and any managing director
• Financial year
• Attached formation documents (articles of association, shareholders’ decision, subscription list)
• Bank confirmation of share capital payment
• Power of attorney (if filed by an authorised representative)

The PRH registration fee must be paid at the time of filing. Online filing attracts a lower fee than paper filing. Notifications and applications must be filed online with the Finnish Trade Register as required by current PRH rules. If PRH identifies errors or missing information, the registrar will issue a request for correction, respond promptly to avoid processing delays. Once approved, the company receives a Business ID (Y‑tunnus), which serves as its unique identifier across all Finnish government interactions.

Processing time for a straightforward online filing is typically one to three business days. Filings that require manual review, for example, those involving foreign‑notarised documents or unusual articles of association provisions, may take longer.

Step 4, Register for VAT, the Prepayment Register and the Employer Register

At the same time as filing the start‑up notification (or separately through Vero’s own services), register the company for the relevant tax registers:

• VAT Register. Registration is mandatory if the company carries on VATable business activities. Voluntary registration is possible even below any applicable threshold and is often advisable to enable input VAT deductions from the outset.
• Prepayment Register (ennakkoperintärekisteri). Ensures that clients do not need to withhold tax from payments to the company. Registration is standard for most businesses.
• Employer Register. Required before the company pays its first wages. Register before the first employee starts work.

VAT registration is processed by Vero and typically takes one to ten business days. There is no fee for registering with Vero’s tax registers.

Step 5, Complete Post‑Registration Steps

After the company is entered in the Trade Register and receives its Business ID:

1. Maintain the shareholder register. The board of directors must keep an up‑to‑date register of shareholders as required by the Limited Liability Companies Act (624/2006).
2. Set up accounting and bookkeeping. Finnish companies must keep accounts in accordance with the Accounting Act. Engage a qualified accountant, particularly if the company will have employees or cross‑border transactions.
3. Appoint an auditor (if required). An auditor must be appointed if the company exceeds specified size thresholds (balance sheet, turnover, employees) for two consecutive financial years, or if the articles of association require it.
4. Establish payroll. If the company has employees, payroll reporting obligations to Vero begin immediately.
5. File annual accounts. Financial statements must be filed with PRH after each financial year end within the deadlines specified in the Companies Act.

Registration Timeline Summary

The entire procedure, from document preparation to receiving the Business ID, can be completed in as little as three to five business days for Finnish or EEA founders using electronic filing. For non‑EEA founders requiring notarisation, the realistic end‑to‑end timeline is typically three to six weeks.

Documents Needed to Register a Company in Finland

The following table lists the documents required for company registration in Finland, together with notes on who issues each document, its format and any validity considerations. Having all documents prepared before filing prevents corrections and delays at the PRH review stage.

Founders with complex ownership structures, such as multi‑layered corporate shareholders or cross‑border nominee arrangements, should have a corporate lawyer verify the documents before submission. Errors in the articles of association or missing signatures are among the most common causes of PRH rejection or requests for correction.

Timeline and Key Deadlines for Company Registration in Finland

Beyond the initial registration window, several post‑registration deadlines govern ongoing compliance. Missing these deadlines can trigger penalties, removal from registers or restrictions on business operations.

Checking Your Registration Status

Once the company is registered, you can verify its status and Business ID through the free YTJ company and organisation search at ytj.fi. The search displays the company’s registered name, Business ID, domicile and the registers in which it is enrolled (Trade Register, VAT Register, Prepayment Register, Employer Register). PRH’s Trade Register also provides official extracts for a fee.

Costs, Fees and Tax Considerations for Company Registration in Finland

The direct costs of registering an Oy are modest by international standards. The main expense categories are the official PRH registration fee, professional service fees and bank‑related costs.

Key Tax Notes

Finland’s corporate income tax is levied on the company’s worldwide income. The standard VAT rate applies to most goods and services, with reduced rates for certain categories. Founders should confirm current rates and thresholds directly with Vero, as these are subject to legislative change. Registering for the Prepayment Register at the time of formation is strongly recommended, without it, clients paying the company must withhold tax from their payments, which creates administrative friction and cash‑flow delays.

What Changes in 2026, PRH and Business Finland Updates

Two institutional developments in 2026 have practical implications for anyone planning to register a company in Finland this year.

Business Finland Reorganisation (Effective 1 January 2026)

Business Finland underwent an organisational restructuring effective 1 January 2026. Industry observers expect that contact points for funding applications and innovation services may have shifted, and processing windows for funding decisions could differ from prior years. Founders intending to apply for Business Finland grants or innovation funding should consult the current Business Finland website for updated application portals and expected decision timelines.

New Trade Register Act, Phased Roll‑Out (2026–2027)

PRH is implementing the New Trade Register Act in phases. From 2026, companies must submit details to the Finnish Trade Register through updated e‑service workflows, and PRH has introduced new data submission fields and enhanced verification procedures. Additional measures, including possible annual verification obligations, are expected to take effect in 2027. The likely practical effect will be an additional one to two weeks of processing time for certain filings during the transition period. Companies should monitor the PRH news feed and the YTJ service announcements for scheduled verification windows and any changes to required data fields.

Early indications suggest that the phased implementation is proceeding on schedule, but founders filing during 2026 should build a buffer into their registration timeline and verify current form requirements on ytj.fi before submitting.

Common Pitfalls in Finland Company Registration and How to Avoid Them

• Incorrect or incomplete articles of association. Missing mandatory provisions (name, domicile, line of business) will trigger a PRH correction request. Use the PRH/YTJ template or have a lawyer draft bespoke articles.
• Missing shareholders’ decision. The founding decision must be signed by all subscribers. An unsigned or incomplete decision delays registration.
• Foreign signature delays. Notarisation and apostille processing in some countries takes two to four weeks. Begin the signing process as early as possible.
• Choosing the wrong company form. Registering a branch when a subsidiary (Oy) would better serve fundraising or liability goals, or vice versa, creates costly restructuring later.
• Mis‑timed VAT or employer registration. Failing to register for VAT before the first taxable supply, or for the Employer Register before the first salary payment, can result in penalties and back‑assessments.
• Bank KYC delays. Not preparing KYC documentation (certified IDs, source‑of‑funds evidence, business plan) before approaching the bank is the single most common cause of extended timelines for foreign founders.
• Misunderstanding director residency rules. At least one board member must be EEA‑resident unless PRH grants an exemption. Appointing only non‑EEA directors without seeking an exemption will block registration.
• Ignoring 2026 PRH verification requirements. Filings submitted without the updated data fields required under the New Trade Register Act may be returned for correction. Check the current YTJ form version before filing.

When to call a lawyer: Engage a Finnish corporate lawyer if you have multiple shareholders with a shareholders’ agreement, cross‑border ownership structures, plans to seek venture capital or Business Finland funding, or if any director or shareholder is located outside the EEA. You can find a Finland business lawyer through our directory.

Conclusion, Next Steps for Registering Your Company in Finland

The process of how to register a company in Finland is efficient and largely digital, but it rewards thorough preparation, particularly for foreign founders navigating bank KYC, notarisation and the 2026 Trade Register changes. Gather your formation documents early, confirm your eligibility and director appointments, and use the YTJ online service for the fastest processing. For complex structures or cross‑border ownership, professional legal advice at the outset will save time and prevent costly corrections later. Monitor PRH and Business Finland communications throughout 2026 for updated verification windows and funding application procedures.
