How to register an enskild firma (sole trader) in Sweden, step by step

An enskild firma (sole trader) is the simplest business structure in Sweden: one owner, no start-up capital requirement, and no separate legal entity. Registration is a two-track process, one track voluntary, one mandatory. This page follows the rules as published by Bolagsverket.

Who can register

You need a Swedish personal identity number (personnummer) or a co-ordination number (samordningsnummer) when registering as a sole trader in Sweden. Without either, see starting a business in Sweden as a foreign citizen.

Track 1: Bolagsverket registration (normally voluntary)

Registering with Bolagsverket is voluntary for most sole traders, with defined exceptions listed on Bolagsverket’s “Obligation to register” page. What voluntary registration buys:

• Business name protection in the county of registration: the registered name cannot be used by another business registered in the same county.
• A certificate of registration.

The steps:

1. Apply using form “Registration as a sole trader”, number 903 e, or apply online at verksamt.se if you have a Swedish electronic identification. The e-service is in Swedish only.
2. Submit additional details if Bolagsverket asks. Questions and replies are handled through email via verksamt.se.
3. Bolagsverket registers the business after approving the proposed business name. The processing time is normally about one to two weeks, and a certificate of registration is sent in Swedish.

Practical warning from Bolagsverket: do not order a domain name or printed material before the business name has been approved and registered.

Track 2: Skatteverket registration (mandatory)

Every sole trader must register with the Swedish Tax Agency. In the online route, this happens in the same application: when registering online, an F-tax card application and VAT accounting registration can be submitted to Skatteverket at the same time. F-tax is what lets clients pay without deducting tax, and it is the registration clients will ask for; see how to apply for F-skatt. VAT applies above the turnover threshold; see VAT for small businesses in Sweden.

What registration costs

There is no start-up capital requirement. Bolagsverket charges fees only for specific registrations, such as registering the business name; check the current fee list on Bolagsverket’s sole trader fees page before applying.

After registration

The business result is declared inside the personal income return, with the NE-bilaga attached to Inkomstdeklaration 1. The full chain of forms and deadlines is covered in the Swedish small business forms guide and the 2026 tax deadlines.
