🇸🇪 Cumplimiento anual — Sweden

Underestimating employer social contributions

Fix: Employer social contributions (arbetsgivaravgifter) are 31.42% of gross salary — this is on top of the salary, not deducted from it. A developer earning SEK 50,000/month costs the company SEK 65,710/month before any other benefits. Build this into your financial projections from the start.

Not registering for F-tax before invoicing

Fix: Without F-tax registration (F-skatt), clients are required to deduct 30% withholding tax from payments to your company. Apply for F-tax registration through Skatteverket as part of your initial setup. The registration confirms that your company handles its own tax obligations.

Ignoring the statutory audit requirement

Fix: Companies exceeding two of three thresholds — 3 employees, SEK 3 million in total assets, or SEK 3 million in net revenue — for two consecutive years must appoint a qualified auditor. Many growing startups cross these thresholds quickly. Budget for audit costs (SEK 15,000–50,000 annually) and engage an auditor before the requirement is triggered.
