How to Register a Foreign Company in Finland (branch or Subsidiary), 2026 Step-by-step Guide

Any foreign company planning to operate in Finland must register with the Finnish Patent and Registration Office (PRH) through the Trade Register, and understanding how to register a foreign company in Finland correctly is critical to avoiding delays, rejected filings, and missed tax obligations. The registration process applies whether you are establishing a branch of your existing parent company or incorporating a new Finnish private limited company (osakeyhtiö, or “Oy”) as a subsidiary. Since 1 January 2026, PRH requires all Trade Register notifications to be filed online through the YTJ Business Information System, ending the previous option of paper submissions.

The Finnish Tax Administration (Vero) has simultaneously introduced updated employer and branch reporting fields that must be completed at the start-up notification stage. This guide sets out the full procedure, eligibility requirements, numbered steps, required documents, realistic timelines, costs, and the 2026 compliance changes, so that founders, in-house counsel and CFOs can move from decision to operational presence with clarity.

Overview of the Registration Process and Who It Applies To

Foreign companies entering the Finnish market face a threshold decision: register a branch (sivuliike) of the parent company, or incorporate a Finnish subsidiary (Oy). The branch is not a separate legal entity, the parent company remains fully liable for its obligations. A subsidiary, by contrast, is a distinct Finnish company with limited liability, governed by the Limited Liability Companies Act (Osakeyhtiölaki 624/2006).

Finland is consistently ranked among the easiest jurisdictions in Europe for foreign business establishment. EU/EEA nationals and companies face no additional residence or permit requirements. Non-EU companies can register freely, though individual founders may need a residence permit depending on their personal involvement.

Quick Decision Matrix: Branch vs Subsidiary

• Branch (sivuliike). Best suited for companies testing the Finnish market, executing a specific project, or wanting to avoid incorporating a new entity. The parent company bears full liability. Accounting must follow Finnish standards for the branch’s operations. A branch must appoint a representative domiciled in the European Economic Area (EEA).
• Subsidiary (Oy). Preferred where limited liability is essential, where the operation will be permanent, or where Finnish clients and banks expect a local company structure. Requires a minimum share capital of €2,500 under the Limited Liability Companies Act. At least one board member must be resident in the EEA.
• Hybrid considerations. Some foreign groups register a branch first to commence operations quickly, then convert to an Oy once the business case is proven. The registration steps for each structure differ and are set out below.

Eligibility and Requirements for Foreign Company Registration in Finland

EU/Nordic vs Non-EU Company Differences

Companies registered in an EU or EEA member state, or in a country with which Finland has a bilateral agreement, can establish a branch or subsidiary without additional government permits. The right of establishment under EU law applies directly. Non-EU companies have the same right to register, but individual directors or signatories who plan to reside in Finland may need to obtain a residence permit, specifically, the entrepreneur residence permit administered by the Finnish Immigration Service (Migri). Detailed guidance on residence permits for foreign entrepreneurs is published by InfoFinland.

Branch vs Subsidiary Legal Prerequisites

Before filing, the parent company must satisfy several corporate prerequisites. For a branch, the parent company’s governing body must pass a formal resolution authorising the establishment of the Finnish branch, naming the branch representative and defining the scope of operations. The representative must be domiciled in the EEA. For a subsidiary (Oy), the founders must prepare and sign a memorandum of association and articles of association that comply with the Limited Liability Companies Act. A minimum share capital of €2,500 must be deposited into a Finnish bank account before or promptly after registration.

In both cases, documents originating outside Finland, board resolutions, certificates of incorporation, powers of attorney, must be notarised in the country of origin, apostilled (if the issuing country is party to the Hague Apostille Convention), and translated into Finnish, Swedish, or English by a certified translator. For companies established in Italy, this means engaging an Italian notary for authentication, obtaining the apostille from the competent Italian court (Procura della Repubblica), and commissioning a certified Finnish or English translation.

How to Register a Foreign Company in Finland: Step-by-Step Procedure

The following six steps cover both branch registration and subsidiary incorporation. Where the procedures diverge, the differences are noted within each step. After 1 January 2026, all filings must be made through the YTJ online portal (ytj.fi), which is jointly operated by PRH and Vero.

Step 1, Conduct Pre-Transaction Checks and Reserve a Company Name (Oy Only)

Search the PRH Trade Register and the YTJ Business Information System to confirm that your proposed company name is available and does not conflict with existing registrations. For an Oy, name reservation is recommended before signing incorporation documents. For a branch, the branch will operate under the parent company’s name, with “sivuliike Suomessa” (branch in Finland) appended. Determine the structure (branch or Oy), confirm that all corporate prerequisites are met, and instruct counsel if needed.

• Who does it: Parent company and legal counsel.
• Typical duration: 1–7 days.

Step 2, Prepare and Sign Incorporation or Branch Documentation

For an Oy, draft and sign the memorandum of association and articles of association in accordance with the Limited Liability Companies Act. Appoint the board of directors (at least one member must be EEA-resident). For a branch, prepare minutes of the parent company’s board resolution authorising the branch establishment, naming the Finnish representative and specifying the scope of business. All documents originating abroad must be notarised, apostilled (where applicable), and certified-translated. Italian parent companies should allow additional time for notarisation at the Italian notary and apostille from the Procura della Repubblica.

• Who does it: Parent company board, notary public, certified translator.
• Typical duration: 3–14 days (longer if apostille or translation turnaround is slow).

Step 3, File the Start-Up Notification (Y1) and Branch Notification via PRH/YTJ Online

Submit the Y1 start-up notification through the YTJ online filing portal. Since 1 January 2026, PRH no longer accepts paper filings, all Trade Register notifications must be submitted electronically. The Y1 form covers both PRH (Trade Register) and Vero (tax registrations) in a single submission. For a branch, additional branch-specific fields must be completed, including the parent company’s foreign registration number, the name and contact details of the EEA-resident representative, and the branch’s Finnish address.

Pay the PRH filing fee online at the time of submission. The fee amount varies depending on whether you are registering a branch or incorporating an Oy, confirm the current fee on the PRH website before filing. Simultaneously select the Vero registrations you require: VAT register, Prepayment Register, and employer register. The 2026 Vero reporting updates require additional employer and branch data fields to be completed at this stage.

• Who does it: Company or authorised representative / Finnish legal agent.
• Typical duration: Online submission is immediate; PRH processing and Trade Register publication typically takes 1–10 working days.

Step 4, Obtain the Business ID (Y-tunnus) and Complete Tax Registrations

Once PRH processes the Y1 notification, the company or branch is assigned a Business ID (Y-tunnus), Finland’s unique business identifier. This number is required for all subsequent dealings with Finnish authorities, banks, and counterparties. Tax registrations selected on the Y1, VAT, Prepayment Register, employer register, are processed automatically by Vero via the linked YTJ system. Under the 2026 Vero reporting rules, branches and employers must provide updated data elements including enhanced payroll reporting details at this stage.

• Who does it: Company or local tax advisor.
• Typical duration: 1–10 working days (automated through YTJ).

Step 5, Open a Finnish Bank Account and Deposit Share Capital (Oy)

Open a Finnish bank account in the name of the registered entity. For an Oy, the minimum share capital of €2,500 must be deposited into this account. Finnish banks conduct thorough KYC (know-your-customer) due diligence on foreign applicants. Expect to provide apostilled and translated corporate documents, passport copies of beneficial owners, and proof of the source of funds. Some banks require the physical presence of a signatory, confirm this requirement with the chosen bank before travelling. Branch registrations do not require capital deposits but will need a Finnish bank account for operational purposes and tax payments.

• Who does it: Company directors and the Finnish bank.
• Typical duration: 3–14 days (bank KYC timelines vary significantly).

Step 6, Complete Post-Registration Employer and Compliance Set-Ups

Once registered, the branch or Oy must set up ongoing compliance obligations. If hiring employees in Finland, register with an earnings-related pension insurance provider (TyEL), arrange statutory workers’ compensation and group life insurance, and set up payroll reporting. File employer prepayment returns with Vero and ensure compliance with the Occupational Safety and Health Act. These obligations apply from the date the first Finnish employee commences work. Early engagement of a Finnish payroll provider or accounting firm is advisable.

• Who does it: Employer or outsourced payroll/accounting provider.
• Typical duration: 5–15 days for initial setup; obligations are ongoing.

Required Documents Needed to Register a Foreign Company in Finland

The following checklist covers the documents needed for both branch and subsidiary registration. All foreign-language documents must be accompanied by a certified translation into Finnish, Swedish, or English. Documents issued outside Finland generally require notarisation and apostille (or, for non-Hague Convention countries, consular legalisation).

For Italian parent companies, the certificate of incorporation is typically the visura camerale issued by the relevant Italian Chamber of Commerce, which must then be apostilled by the Procura della Repubblica and translated by a certified translator.

Timeline and Key Deadlines for the Registration Process

The overall timeline from initial decision to fully operational status typically ranges from 2 to 8 weeks, depending on the complexity of the structure, the speed of document preparation abroad, and bank KYC processing times. The table below summarises realistic durations for each step.

Key statutory deadlines to note: the branch notification must be filed with PRH before the branch commences business operations in Finland. For an Oy, the Y1 start-up notification must be filed within three months of signing the memorandum of association; failure to file within this window means the incorporation lapses. Vero employer registration should be completed before the first salary payment is made to any Finnish-based employee.

Costs, Fees and Tax Considerations

The total cost of registering a foreign company in Finland varies depending on the chosen structure, the country of origin (which affects notarisation and apostille costs), and whether legal or advisory assistance is used. The following table provides indicative figures, exact PRH fee amounts should be confirmed on the PRH website at the time of filing, as they are updated periodically.

Beyond registration fees, foreign companies should budget for initial tax obligations. Registering for the Prepayment Register means the company can receive payments without clients withholding tax. VAT registration is required once taxable turnover in Finland exceeds the applicable threshold, companies expecting to exceed this should register at the outset. Employer obligations include TyEL pension contributions, social security contributions, and statutory insurance premiums, which are ongoing costs commencing from the first day of employment.

What Changes in 2026: PRH Mandatory Online Filing and Vero Reporting Updates

Two regulatory changes effective in 2026 directly affect the registration process for foreign companies in Finland.

PRH mandatory online filing (from 1 January 2026). All Trade Register notifications, including start-up notifications (Y1) and branch notifications, must now be submitted electronically through the YTJ portal or via PRH’s online services. Paper submissions are no longer accepted. This means that the authorised representative or filing agent must have access to Finnish electronic identification (such as Suomi.fi e-identification) or use a local agent with such access. Foreign companies that previously relied on postal filings must now engage a Finnish-based representative or service provider capable of submitting electronically.

Vero 2026 reporting rule updates. The Finnish Tax Administration has introduced updated data fields for employer and branch reporting effective 2026. Start-up notifications now require enhanced payroll and employer information, including more detailed reporting of employee categories and payroll frequency data. Companies registering as employers must ensure these additional fields are completed accurately on the Y1 form to avoid processing delays.

Industry observers expect these changes to accelerate processing times for correctly completed filings, but they also increase the risk of rejection for companies unfamiliar with the new electronic requirements.

2026 Compliance Checklist

• Confirm your authorised representative has Finnish electronic identification or engage a local filing agent.
• Prepare all supporting documents in electronic format (scanned, certified copies).
• Review the updated Y1 form fields on the YTJ portal before submission, branch-specific and employer-specific sections have changed.
• Verify current PRH fee amounts online, as online-only filing may have adjusted the fee schedule.
• Complete all Vero employer reporting fields at the start-up notification stage to avoid follow-up requests.

Common Pitfalls When Registering a Foreign Company in Finland, and How to Avoid Them

• Filing via paper or filing late. Since 1 January 2026, paper submissions are rejected outright. For an Oy, failing to file the Y1 within three months of signing the memorandum of association causes the incorporation to lapse entirely. Always file electronically through YTJ and track the three-month deadline carefully.
• Incomplete Y1 fields for branch registration. Branch notifications require fields that are not needed for an Oy, including the parent company’s foreign registration number, details of the EEA-resident representative, and the branch’s Finnish address. Leaving these blank delays processing or triggers a deficiency notice from PRH.
• Uncertified translations or missing apostilles. PRH will not process documents that lack proper authentication. Ensure every foreign-language document is accompanied by a certified translation into Finnish, Swedish, or English, and that originals carry the required apostille or consular legalisation.
• Delayed Vero employer registration. Employers must be registered with Vero before making the first salary payment. Late registration can result in penalties and missed prepayment deadlines. Complete all employer registration fields on the Y1 at the time of initial filing.
• Bank account delays due to inadequate KYC preparation. Finnish banks apply rigorous KYC procedures to foreign applicants. Gather apostilled corporate documents, beneficial ownership information, and proof of source of funds before approaching the bank. Some banks require physical attendance, confirm requirements in advance to avoid unnecessary travel.
• Failing to appoint an EEA-resident representative (branch). A branch must have a representative domiciled in the EEA. This is a mandatory requirement, PRH will not register the branch without it.
