Sole trader or limited company: which should you start?

One of the first decisions a new entrepreneur makes is the form of the business. In Finland, most small businesses start either as a sole trader (toiminimi) or as a limited company (osakeyhtiö).

The short answer: a sole trader is usually the simplest choice when you start small and want to test an idea. A limited company makes more sense when the profit grows, the risks are larger or you plan to bring in employees, partners or investors.

There’s no single right answer, but there is usually a right answer for you. Below we compare sole trader vs limited company on liability, taxes, paperwork and costs.

Sole trader: simple and quick to start

A sole trader is the easiest way to start. You file a start-up notification through the YTJ service (ytj.fi), run jointly by the Finnish Patent and Registration Office (PRH) and the Finnish Tax Administration. There is no share capital, no board and no shareholders’ meetings.

Bookkeeping is lighter, and you can move money between the business and yourself freely. Money you take out is a private withdrawal, not a salary, so there is no payroll to run for yourself.

The catch is liability: as a sole trader you are personally responsible for the business’s debts and commitments. If the business can’t pay its bills or a customer claims damages, your personal savings and property are at stake.

The profit is also taxed as your own income. Earned income tax is progressive, so a growing profit makes your taxation heavier — and you pay tax on the whole profit, even on money left in the business account.

Limited company: separate from you

A limited company is a separate legal entity. It owns its assets, signs its own contracts and is responsible for its own debts. Your liability as a shareholder is generally limited to what you have invested in the company.

There are exceptions. Personal guarantees, for example for a bank loan or lease, apply to you personally, and banks often ask small-company owners for one. Board members can also be liable for damage caused by neglecting their duties.

Since 2019 a Finnish private limited company no longer needs a minimum share capital. You still need a memorandum of association and a board — in a one-person company, typically you plus a deputy member.

The company’s money is not your money, even if you own every share. You take it out as salary or dividends, each with its own rules and taxation; withdrawals without a proper decision can lead to unpleasant tax consequences.

How the taxes differ in practice

Taxation is often why people compare sole trader vs limited company. A sole trader’s profit is taxed once, in the owner’s personal taxation; a limited company’s profit is taxed first in the company, then again when it is paid out to the owner as dividends.

For a sole trader, part of the profit can be taxed as capital income if the business had net assets at the end of the previous year; the rest is earned income. In a limited company:

• The company pays corporate income tax at a flat rate. Check the current rate on vero.fi, as it can change.
• Salary you pay yourself is taxed as earned income and reported to the Incomes Register.
• Dividends from a non-listed company are taxed under rules that depend on, among other things, the company’s net assets and the amount paid.
• Profit you leave in the company is only taxed at the corporate rate until you take it out.

That last point is why a limited company can become more tax-efficient as the profit grows: you decide how much to take out each year and leave the rest for investments or quieter periods.

There is no single euro limit where switching pays off. It depends on your profit, your living costs and your plans — an accountant can calculate both options with your own figures.

Paperwork and costs

A limited company comes with more administration: double-entry bookkeeping, annual statutory financial statements filed with the public Trade Register, and documented shareholder decisions, for example on dividends.

Paying yourself a salary means running payroll and reporting each payment to the Incomes Register. Dividends can only be paid if the company has distributable funds and remains able to pay its debts.

In practice most limited companies use an accountant, which is an extra monthly cost. The registration fee is also typically higher than for a sole trader; check the current fees on the PRH website.

A sole trader’s accounting is lighter, but it still has to be done properly: keep business and private money in separate bank accounts, save every receipt and record transactions regularly — good bookkeeping pays off in both forms.

What stays the same in both forms

Some obligations don’t depend on the business form at all, so they shouldn’t drive your decision:

• Entrepreneur’s pension insurance (YEL): compulsory for sole traders whose work income exceeds the minimum level, and usually also for limited company owners in a managerial position with a large enough share. Your work income also affects your social security.
• VAT: the same registration rules apply to both forms. Whether you must register depends on your turnover; check the current limit on vero.fi.
• Prepayment register: worth joining in both forms, because customers who pay you for work generally have to withhold tax if you are not registered.
• Insurance: liability insurance matters in both forms. Accident insurance for yourself as an entrepreneur is voluntary, but worth considering.

So a limited company does not get you out of pension contributions, and a sole trader is not exempt from VAT. The real differences are liability, taxation and administration.

Which one should you choose?

• Choose a sole trader if you are testing an idea, your income is modest and the risks are small.
• A sole trader also suits you if you want the lightest possible administration and plan to work alone.
• Choose a limited company if the profit is growing, the risks are significant, or you plan to hire or bring in partners or investors.
• A limited company also makes sense if you want to keep part of the profit in the business for future investments.

Partners and investors are the clearest case: a limited company is built for shared ownership. General and limited partnerships also exist, but in both at least one partner is personally liable for the debts.

You don’t have to decide forever. Many entrepreneurs start as a sole trader and switch to a limited company once the business grows.

Questions to ask yourself before you register

Before you fill in the start-up notification, go through these questions:

• How much profit do you expect in the first few years, and how much of it do you need to live on?
• What is the worst thing that could go wrong — a damages claim, an unpaid invoice, a long lease?
• Will you need a loan, and is the bank likely to ask for a personal guarantee anyway?
• Do you plan to hire employees, bring in a business partner or look for investors?
• How much time and money are you willing to spend on administration each month?

Bring your answers to your first meeting with an accountant. With a rough budget in hand, the comparison becomes concrete instead of guesswork.

Switching to a limited company later

Starting as a sole trader does not lock you in. You can later transfer the business to a new limited company, under certain conditions without immediate income tax consequences — ask your accountant whether your case qualifies.

A practical checklist for the switch:

• The limited company gets a new business ID, so update your invoice templates, website and bank details, and tell customers in advance.
• Agreements with customers, suppliers and your landlord may need to be transferred or signed again.
• VAT, prepayment and, if needed, employer registrations are made for the new company.
• Your YEL insurance and other policies are reviewed to match the new form.

Timing matters too: a change at the start of a financial year often keeps the bookkeeping clearer.

Summary

A sole trader is fast and simple; a limited company separates you from the business and can be more tax-efficient as profits grow. Pension insurance, VAT and careful bookkeeping apply either way.

When weighing sole trader vs limited company, look at your expected income, risks and plans, and ask an accountant to run the numbers for your situation. Check current tax rates and fees on vero.fi and prh.fi.
