Everything Swedish sole traders (enskild firma) need to know about 25% Moms, the F-skatt certificate, egenavgifter social contributions, SINK for non-residents, and Skatteverket invoice rules — in plain English.
The simplest legal form for a Swedish freelancer is the enskild firma (sole proprietorship / enskild näringsidkare). You and the business share a single personal identity number (personnummer) — there is no separate legal entity and no share capital required.
Key characteristics:
Most solo freelancers and consultants use enskild firma until turnover and profit make a limited company (aktiebolag — minimum SEK 25,000 share capital) worthwhile.
F-skatt (Företagsskatt) is the tax certificate that proves to your clients you are responsible for paying your own income tax and social contributions. Without it, Swedish clients are legally required to withhold tax and pay employer contributions on your invoices — and most simply refuse to hire freelancers without F-skatt.
How it works:
At year-end, the preliminary tax paid is reconciled with your actual tax in the Inkomstdeklaration (annual return, due by 2 May).
Sweden's standard VAT rate (Moms) is 25% — among the highest in the EU. Reduced rates:
VAT registration becomes mandatory when annual turnover exceeds SEK 120,000. Below that you can choose to stay unregistered (no Moms on invoices, no input VAT reclaim) or register voluntarily.
Filing frequency depends on turnover:
Returns and payment go through Skatteverket's e-service with BankID.
Swedish self-employed pay egenavgifter instead of the arbetsgivaravgifter (employer contributions) that companies pay for staff. The total rate for a standard enskild firma is approximately 28.97% of net business profit in 2026.
The rate is split across:
Reduced rates apply for:
Egenavgifter are calculated annually on your NE-bilaga and paid as part of preliminary F-skatt monthly.
Sweden's income tax for self-employed has two layers:
For an enskild firma, the taxable amount is your business profit (revenue – expenses – egenavgifter – pension allocation) added to other personal income.
Key deductions for sole traders:
If you live abroad and work in Sweden for less than six months, you can apply for SINK (Särskild inkomstskatt för utomlands bosatta) — a special flat tax for non-residents.
2026 update: The SINK rate was reduced from 25% to 22.5% effective 1 January 2026, and will drop further to 20% in 2027.
Key points:
SINK is typically used by consultants and specialists on short Swedish assignments. If your Sweden stay exceeds 6 months you become tax-resident and standard rates apply instead.
