Start Your Own Business in Finland

Self-employment is the starting point. When you are ready to protect your personal assets, bring on partners, or unlock tax advantages, it may be time to form a company in Finland.

HustleHub AI provides general information only, not tax, legal, or financial advice. Finnish rules may vary. Always check Verohallinto or PRH, or speak to a qualified tilitoimisto or asianajaja.

From side hustle to business owner

Many successful businesses start as side hustles. The typical progression in Finland:

1

Side hustle

Earning extra income alongside your main job. Casual, flexible, low commitment.

2

Toiminimi

Registered sole trader via PRH. Y-tunnus. Ennakkoverot. You and the business are one legal entity.

3

Osakeyhtiö (Oy)

Private limited company. Separate legal entity. Limited liability. Yhteisövero 20%.

Not everyone needs to progress to step 3. Many self-employed people stay that way permanently and do very well.

When to stay solo vs form a company

Stay self-employed when...

  • Low-risk business with modest income
  • You are testing an idea or starting a side hustle
  • You want minimal paperwork and affordable setup (~EUR 60)
  • You benefit from the YEL new entrepreneur discount (22% off for 48 months)

Consider an Osakeyhtiö (Oy) when...

  • You want personal liability protection
  • Your income is high enough that yhteisövero 20% is more favorable than progressive personal rates
  • You plan to take on partners or investors
  • Clients or public contracts require a company structure

How to form a company in Finland

  • Choose a company name (check availability at PRH)
  • Prepare yhtiöjärjestys (articles of association)
  • Deposit EUR 2,500 minimum share capital (or no minimum since 2019)
  • Register the Oy at PRH via YTJ.fi (costs EUR 240-380)
  • Appoint at least one hallituksen jäsen (board member) and optionally a toimitusjohtaja (CEO)
  • Register for yhteisövero (corporate tax) at Verohallinto
  • Open a business bank account in the company name
  • Set up payroll (palkanmaksu) if paying a salary
  • Register for employer TyEL pension insurance
  • Appoint a tilintarkastaja (auditor) unless qualifying for exemption

Finland effectively removed the Oy minimum share capital in July 2019 (EUR 2,500 remains standard). The yhteisövero (corporate tax) rate of 20% is competitive. New entrepreneurs get a 22% YEL discount for 48 months. Finland uses the euro, simplifying cross-border trade.
