Starting a Company and Choosing a Name

Forms of Business and Companies in Finland

Once a business idea has been developed and it has been determined how the future business will create value and generate revenue, the next step is to choose a suitable form of entrepreneurship and legal form for the company.

The choice depends on whether the entrepreneur will work alone or with partners, how large the business is expected to be, what risks are involved, and how the company is intended to develop.

It is important to distinguish between a form of entrepreneurship and a legal form of company. For example, an entrepreneur may start working independently, operate part-time, or use a franchise model, while the legal form of the business may be a private trader or a limited liability company.

Forms of Entrepreneurship

In Finland, entrepreneurial activities can be organised in different ways. It is not always necessary to establish a separate company immediately when starting a business.

Entrepreneurship can be pursued alongside regular employment, studies or other activities, meaning that the business is operated part-time. This approach allows an entrepreneur to gradually test a business idea, gain initial experience and assess demand for a product or service without giving up their main occupation.

Light entrepreneurship allows individuals to sell their services without establishing their own company in the traditional sense. Depending on the model used, the service provider handles invoicing, while the entrepreneur receives payment after the applicable charges and service fee have been deducted.

Light entrepreneurship can be suitable for testing a business idea or completing individual assignments. However, before starting, it is important to understand how the chosen service handles invoicing, taxation and other obligations.

An entrepreneur can establish their own business and take responsibility for its operations, customers, income, expenses and development. Depending on the chosen business form, this may involve operating as a private trader, a limited liability company (Osakeyhtiö) or another legal form.

A business can be established together with another entrepreneur or several partners. In this case, it is important to agree in advance on the division of responsibilities, decision-making, financing, profit distribution and liability. Some partnership forms require at least two partners. For example, a general partnership and a limited partnership cannot be established by one person alone.

Under a franchise model, an entrepreneur uses an established business concept, brand, products or services and operating system provided by the franchisor. This can provide access to an already developed business model and a recognised brand, but the entrepreneur must comply with the terms of the franchise agreement and normally pay fees associated with using the system.

In team entrepreneurship, several entrepreneurs combine their knowledge, skills and resources to create a joint business. Participants often have different professional backgrounds and may also run their own businesses alongside their involvement in the joint venture.

This approach makes it possible to combine different areas of expertise, share responsibilities and risks, and make use of the resources available within the team. A joint business can, for example, be organised as a limited liability company (Osakeyhtiö, Oy) or a cooperative (Osuuskunta).

A startup is typically established to develop a new product or service and scale the business rapidly. Unlike a conventional small business, a startup is often focused on fast growth and may require external financing.

A freelancer provides services independently to clients, usually working on individual projects or assignments. Freelancing is not itself a separate legal form of business. Different models can be used to operate as a freelancer, including providing services through one's own company.

Instead of starting a business from scratch, an entrepreneur can acquire an existing company or an established business. This option may provide access to an existing customer base, equipment, employees, contracts and business processes. However, before making a purchase, it is important to carefully assess the financial position of the business, its liabilities, contracts and associated risks.

Forms of Companies in Finland

If an entrepreneur decides to establish their own company, they need to choose its legal form. The choice affects, among other things, the entrepreneur's liability, how the company is managed, taxation and administrative obligations. The official Suomi.fi guide provides a comparison of the different company forms.

A private trader (yksityinen elinkeinonharjoittaja) is one of the simplest forms of running a small business, particularly when the business is mainly based on the entrepreneur's own work.

The entrepreneur is personally liable for the business's obligations with all of their personal assets. This means that this form requires particularly careful consideration of financial risks.

A private trader can register in the Trade Register (Kaupparekisteri), although registration requirements depend on the circumstances. The abbreviations “Tmi” and “Toiminimi” are commonly used when referring to a private trader.

Osakeyhtiö is one of the most common company forms in Finland and is suitable for a wide range of business activities. Finland has private limited liability companies (yksityinen osakeyhtiö, Oy) and public limited liability companies (julkinen osakeyhtiö, Oyj). Most small and medium-sized businesses use the private Oy form.

The company is a separate legal entity, so shareholders are generally not personally liable for the company's obligations. However, personal liability can arise in certain situations, for example when an individual provides a personal guarantee for a company loan.

An Oy can also be established by a single person. If the board has one or two ordinary members, it must have at least one deputy member of the board (varajäsen).

A general partnership must have at least two partners. This form may be suitable for a relatively small business where the partners know and fully trust each other. The partners are personally liable for the obligations of the business with their personal assets.

A limited partnership also requires at least two partners. One or more partners are general partners (vastuunalainen yhtiömies), while at least one partner is a silent partner (äänetön yhtiömies).

A general partner is personally and fully liable for the partnership's obligations. A silent partner's liability is generally limited to the amount of their agreed contribution. This form can be used, for example, when an entrepreneur wants to bring in an investor who does not directly participate in managing the business.

A cooperative can be suitable for joint entrepreneurship when several individuals or companies combine their resources, knowledge or professional skills. A cooperative can formally be established by a single person, although in practice this form is typically used for team-based business activities.

The purpose of a cooperative is to support the economic and other activities of its members. Members can use services provided by the cooperative and jointly organise business activities.


How to Choose a Company Form?

There is no single company form that is optimal for every business.

When making the choice, consider:
  • whether the entrepreneur will work alone or with partners;
  • how large the business is expected to be;
  • how significant the financial and other risks are;
  • who will be liable for the company's obligations;
  • how much capital is required to start the business;
  • how the company will be managed;
  • how profits will be distributed;
  • what administrative obligations will arise;
  • what development and growth plans the business has.

For example, a small business based mainly on the entrepreneur's own work may be well suited to operating as a private trader (Tmi). A business with greater risks, several owners or plans for growth may be better suited to an Oy.

The choice should be based not only on how easy it is to establish the company, but also on the business's long-term objectives.

Starting a Company in Finland

Once the company form has been chosen, the entrepreneur must complete the formalities required to establish and register the business. From 1 January 2026, companies must file notifications and applications with the Trade Register (Kaupparekisteri) online. This requirement does not apply to private traders, associations or foundations. More information about mandatory online filing is available on the PRH website. The registration process is also described in the Suomi.fi guide to company registration.

Depending on the business form and the nature of the activity, the following may be required:

  • registration in the Trade Register (Kaupparekisteri);
  • registration in the Prepayment Register (ennakkoperintärekisteri);
  • registration in the VAT Register (alv-rekisteri). A company does not need to register for VAT if its turnover does not exceed €20,000 in either the current or the preceding calendar year. If the turnover exceeds €20,000 during the calendar year, the company must register for VAT from the date on which the threshold is exceeded, and VAT liability begins from that point. Please note: the previous VAT relief for small businesses (alv-alarajahuojennus) was abolished as of 1 January 2025.
  • registration in the Employer Register (työnantajarekisteri), if applicable;
  • preparation of the company's foundation documents;
  • notification of the commencement of business activities.

For Oy, Avoin yhtiö, Ky and Osuuskunta, registration in the Trade Register is mandatory. The rules are different for private traders.

The specific registration requirements depend on the business form and the nature of the business, so current requirements should always be checked before establishing a company.

Choosing a Company Name

A company name is an important part of a business. A good name should be memorable, distinguishable from other names and appropriate for the company's activities.

PRH recommends choosing a company name carefully before submitting the registration documents. However, PRH cannot guarantee in advance that a proposed name will be approved for registration.

Before registration, you can check a proposed name using the Name Checking Service. However, the final decision on whether a name can be registered is made by PRH during the processing of the registration notification.

What Should a Company Name Be Like?

A company name must meet the applicable requirements. PRH checks, among other things:

  • whether the required indication of the company's legal form is included;
  • the uniqueness of the name;
  • its distinctiveness;
  • whether it is insufficiently distinguishable from existing names;
  • the use of personal names;
  • other requirements laid down by law.

A simple description of the business activity is generally not sufficient as a distinctive company name. For example, a name consisting only of a generic description of the type of business may not receive the necessary protection.

A more original and distinctive name will generally provide stronger protection and be easier for customers to remember.

A company name must also not mislead the public or conflict with legal requirements or public order.

Company Name and Trademark

A company name and a trademark are not the same thing.

Registration of a company name in the Trade Register gives the company an exclusive right to the registered name under the rules governing protection of company names. However, protecting a brand, products or services may require a separate trademark registration.

Company Name and Domain Name

Before choosing a company name, it is also worth checking whether the corresponding domain name is available. To check the availability of a .fi domain, you can use the .fi Domain Name Search service.

However, registering a company name does not guarantee that the corresponding .fi domain will be available. Conversely, registering a domain name does not automatically mean that the same designation can be registered as a company name.

It is therefore advisable to check the company name, trademarks and domain name before making a final choice.

From Business Idea to a Registered Company

In summary, starting a business in Finland involves several interconnected steps.

First, the entrepreneur needs to develop and test the business idea, define the business concept and assess its potential. The next step is to choose a suitable form of entrepreneurship and legal form for the company.

The entrepreneur then chooses a company name, checks that it meets the applicable requirements and registers the company, while also completing the necessary tax and other registration formalities.

Choosing the right business form and developing a well-considered company name provide a solid foundation for the company's future development.
