Sweden makes it easy to start a business and rather harder to understand what the form you picked implies. The paperwork is online and shared between agencies; the consequences, liability, tax, contributions, last for years.
This guide takes you through the three main legal forms, the registration steps and the one approval you must not forget when you start a business in Sweden: F-skatt.
Which legal form fits you when you start a business in Sweden?
Enskild firma (sole trader). Just you, with no separation between your assets and the business's. You need a personnummer or a coordination number, and no capital. You do not pay yourself a salary: you make withdrawals, and tax applies to the profit, not to what you withdraw. You answer for debts with your personal assets.
Aktiebolag (AB, limited company). A legal entity. The aktiebolag minimum capital is 25,000 SEK, in cash or in assets useful to the business valued by an authorised accountant. It needs a board of at least one director and one deputy, and at least half of the directors and the managing director must live in the EEA, unless Bolagsverket grants an exemption. Corporate tax is 20.6 per cent of profit. Directors can be personally liable in some cases, for example for unpaid taxes.
Handelsbolag (trading partnership). Two or more partners, each liable jointly for all debts, each taxed on their share of profit.
Dividends from an AB to owner-managers follow special rules for closely held companies (the "3:12" rules), so talk to an accountant before you count on them.

What are the registration steps?
- Choose your form and, for an AB, pay in the capital, write the deed of foundation (stiftelseurkund) and the articles (bolagsordning), then register the company and its beneficial owner with the Companies Registration Office (Bolagsverket).
- For a partnership, register at Bolagsverket through the verksamt.se portal.
- For an enskild firma, registration of the name at Bolagsverket is usually optional. It protects your name and can help for public procurement.
- Apply for F-skatt (or FA-skatt if you stay an employee as well) at the Tax Agency, together with VAT (moms) and employer registration if needed. With a Swedish e-ID, all of it happens in "My pages" on verksamt.se. Without one, use form SKV 4620.
- File a preliminary tax declaration. You estimate your profit and the Tax Agency sets your monthly tax prepayments.
- Check whether your activity needs a licence or permit.
If you have lived in Sweden for less than two years, the Tax Agency may ask for documents showing you have no unpaid taxes abroad, dated within the last three months.
What does it cost, and how long does it take?
According to verksamt.se and Bolagsverket (prices checked in October 2026):
- Aktiebolag: from 2,400 SEK online plus 250 SEK for the beneficial owner; 2,700 SEK with Bolagsverket's paper form.
- Handelsbolag: from 1,800 SEK.
- Enskild firma: optional name registration from 1,800 SEK online (2,100 SEK on paper); deregistration is free. Registration with the Tax Agency is free.
- Bolagsverket's fees carry no VAT.
Processing times change weekly. For a new AB, Bolagsverket reported about eight working days in October 2026. The Tax Agency's registrations (F-skatt, VAT, employer) generally take up to six weeks, longer if it asks questions.
Why is F-skatt the important one?
F-skatt tells your clients that you take care of your own tax and contributions. Without it at the time of payment, your client must withhold tax and pay employer contributions on your invoice, which hurts your relationship and your cash. Write Godkänd för F-skatt on your invoices.
It can be refused. The activity must be independent, for profit and lasting, and one client can be enough. Unpaid taxes, a bankruptcy or a ban on running a business block it.
F-skatt also plays a role in your right of residence: for an EU citizen who is self-employed, it is part of the evidence for the population register. See residence in Sweden for EU citizens. Swiss citizens can start working on arrival without waiting for their residence permit decision, but to run a business they must apply for F-skatt, and they attach it to the permit application with the Bolagsverket registration where needed.
How does tax work after you launch?
The Tax Agency sets your monthly prepayments from your estimate: they are due on the 12th of each month, and on the 17th in January and August. Your annual return reconciles them. As a sole trader you also pay social contributions (egenavgifter) of 28.97 per cent of profit in 2026, lower from age 67. You can stay outside VAT if your turnover is at most 120,000 SEK in the calendar year and was not above that in the two previous years.
Your tax residence still depends on where you live. See income tax in Sweden for new residents. Keep your private and business money apart; bank account in Sweden explains the first account.
What does freelancing in Sweden look like in practice?
Many newcomers start a business in Sweden because they are freelancers: consultants, designers, developers, translators, trades. For freelancing in Sweden with a few clients, the enskild firma is usually the first stop, because it requires no capital and the registration with the Tax Agency is free. You get F-skatt, you issue invoices with Godkänd för F-skatt, you register for VAT on the same Tax Agency form if your activity requires it, and you pay monthly tax prepayments based on your estimated profit.
The routine is simple. Open a separate bank account for the business. Keep every invoice, receipt and contract for seven years. Put money aside for tax from each payment, because the prepayments are a fixed monthly amount while your income may vary. As your income grows, ask whether an aktiebolag would suit you: it separates your assets from the business's and can reassure larger clients, but it requires capital, more formal accounting and an annual report.
What are the common mistakes when you start a business in Sweden?
- Invoicing without F-skatt.
- Underestimating liability. In an enskild firma and a partnership your personal assets answer for debts.
- Trying to pay yourself a salary in an enskild firma. You withdraw, and tax is on the profit.
- Skipping the accountant. Not compulsory for a sole trader, but VAT and prepayments are easier with one.
- Treating the form as final. You can change later, at a cost.
Before you register and choose your legal form, have your plan confirmed by a Swedish accountant (redovisningskonsult) or tax adviser. A one-off meeting before you start costs less than undoing a wrong choice.
What about British founders and foreign companies?
British citizens are third-country nationals since Brexit and need a residence permit from the Migration Agency before starting, unless they hold a Withdrawal Agreement status. See moving to Sweden from the UK.
A company that already exists abroad can ask for F-skatt through the Tax Agency's service for foreign companies, which takes around two to eight weeks if the file is complete. A company that only sells goods does not generally need F-skatt, and it registers as an employer when it signs a first employment contract. A company from outside the EU (the UK included) that has to pay VAT in Sweden must appoint a representative (ombud) established in Sweden or the EEA.
