Sweden has a well-organised contractor market: most freelancers run a sole trader business or a small limited company, hold F-skatt and invoice with a VAT number. That one approval shapes the whole engagement. With it, the contractor pays their own tax and social contributions; without it, Swedish withholding and employer contributions fall on the payer, including a payer abroad. Employment law runs its own test, so F-skatt does not end the classification question. This guide covers the contractor set-up, F-skatt, tax, requalification risk and the contract. The payment side is on our Sweden payouts page. It is general information, not legal advice.
Enskild firma or aktiebolag
A sole trader (enskild firma, formally enskild näringsverksamhet) is the simplest form. The owner registers with the Tax Agency, has unlimited personal liability for the business’s debts, and usually does not need to register with the Companies Registration Office (verksamt.se, checked 2026-09-29). A sole trader whose only income is the business must apply for F-skatt (same source). You contract with the person.
A limited company (aktiebolag, AB) needs at least SEK 25,000 in share capital and registration with the Companies Registration Office, from SEK 2,400; the owner normally has no personal liability (verksamt.se, checked 2026-09-29). You contract with the company, which pays its owner a salary or dividends and handles its own payroll taxes.
Before the first invoice, collect the contractor’s organisation number, their F-skatt confirmation and, if you are an EU business, their VAT number.
F-skatt: why the approval decides who pays tax
Swedish law puts tax on work income at source. Anyone who pays remuneration for work must withhold preliminary tax (Tax Procedure Act, ch. 10 s. 2) and pay employer contributions (Social Contributions Act, ch. 2 s. 1). Both obligations fall away if the recipient is approved for F-skatt either when the fee is agreed or when it is paid (Tax Procedure Act, ch. 10 s. 11; Social Contributions Act, ch. 2 s. 5, checked 2026-09-29).
Without F-skatt, the Tax Agency tells payers to withhold tax, at 30% for a company holding A-skatt, and, where the recipient is an individual, also to pay employer contributions (skatteverket.se, checked 2026-09-29). The employer rate in 2026 is 31.42% (skatteverket.se, checked 2026-09-29). A foreign payer is not exempt: without a Swedish establishment it withholds for work the recipient performs in Sweden (ch. 10 s. 6), and contributions are due on pay for work in Sweden (Social Contributions Act, ch. 2 s. 4).
What to check. The Tax Agency’s “Hämta företagsinformation” service shows F-skatt approval, VAT registration and employer registration; it is open to anyone, needs no e-ID and answers by email (skatteverket.se, above). You may also rely on an F-skatt statement in a document drawn up for the assignment, such as the contract or invoice, if it identifies both parties and you do not know it to be false (ch. 10 s. 12). FA-skatt holders, who combine a business with employment, must cite the F-skatt in writing for each assignment (skatteverket.se, checked 2026-09-29).
Why re-check. The Tax Agency must revoke an approval on set grounds, including unpaid taxes totalling half a price base amount (ch. 9 s. 4), or SEK 29,600 in 2026.
Egenavgifter and the contractor’s own tax
A sole trader pays egenavgifter, self-employment social contributions, on business profit: 28.97% in 2026 for people born in 1959 or later, with a standard 25% deduction for the contributions when profit is calculated. Profit is also subject to municipal income tax, and to 20% state income tax above SEK 643,000 of taxable earned income (skatteverket.se, checked 2026-09-29). The contractor pays through monthly preliminary F-tax; your invoice stays the same.
VAT. The standard rate is 25%. A business with turnover in Sweden of no more than SEK 120,000 a year generally does not need to register for VAT (skatteverket.se, checked 2026-09-29). A service sold to a business in another EU country carries no Swedish VAT: the invoice says “omvänd betalningsskyldighet” (reverse charge) with the buyer’s VAT number (skatteverket.se, checked 2026-09-29), and the contractor reports the sale in a periodic summary.
Requalification risk
Tax status and employment status are separate questions. Swedish courts decide employment on an overall assessment. Signs of employment include work done personally with no right to hire helpers, the company’s equipment, directives and instructions, a duty to work when asked, a guaranteed fee, expenses paid by the company, a long relationship, and a bar on similar work for others. F-skatt normally points to a consultancy, but not when the arrangement is built to sidestep mandatory law (Cederquist via L&E Global, checked 2026-09-29). A worker found to be an employee gains holiday entitlement, sick pay, overtime pay and the dismissal protection of the Employment Protection Act (LAS), which requires objective grounds (same source).
The tax side has its own trigger. If an F-skatt holder is obviously the payer’s employee, the payer must report this to the Tax Agency in writing, by the due date of the employer declaration for that period (Tax Procedure Act, ch. 10 s. 14). See contractor misclassification.
Contract and IP
- A written services agreement with the contractor’s organisation number, F-skatt statement, deliverables, rate, currency and payment terms.
- Independence markers that match reality: the contractor’s own equipment and schedule, the right to use helpers and to work for other clients, and pricing per deliverable where the work allows. Courts look at how the work is done, not the label.
- IP transfer in writing. Under the Copyright Act, copyright in software passes to the employer automatically only when an employee writes it as part of their duties (section 40a). A contractor keeps it unless it is transferred. A buyer of copyright may not alter the work or transfer it further unless agreed (section 28), and moral rights can be waived only for use limited in kind and extent (section 3) (riksdagen.se, checked 2026-09-29). Transfer the rights you need, allow modification and onward transfer, and cover pre-existing material.
Taxes and paperwork on the client’s side
With F-skatt, pay gross against invoices and keep the F-skatt confirmation. US payers collect a W-8BEN (W-8BEN-E for an aktiebolag) and file no 1099: work performed in Sweden is foreign-source income. Under the US–Sweden treaty, signed in Stockholm on 1 September 1994, the US can tax a Swedish resident’s independent personal services only if they are attributable to a fixed base in the US (irs.gov, checked 2026-09-29). EU payers check the VAT number in VIES. Keep the contract, F-skatt confirmation, invoices and proof of payment.
Contractor of Record in Sweden
For long, single-client or full-time engagements, a Contractor of Record puts a contracting party between you and the contractor. 4dev acts as Contractor of Record — the contracting party for each contractor — which reduces reclassification risk. Other providers in our COR rating offer the same model; read the liability clause in the COR contract rather than the product name. If the role is a job in substance, with your hours, your equipment and core work, hire through an EOR instead.
How to pay contractors in Sweden
Pay to the contractor’s Swedish IBAN, not a bankgiro number: kronor through SWIFT or a provider with local SEK payout, or euros over SEPA if the account is in euros. Swish runs only between Swedish bank accounts, and there is no currency control. Rails, fees and a ranked list of platforms are on our page how to pay contractors in Sweden.
