Sweden's employment legislation has undergone significant amendments that take direct effect in 2025. Foreign employers with staff in Sweden – whether through local subsidiaries, posted workers, or direct hiring arrangements – face new compliance obligations. Missing the applicable deadlines carries real legal and financial exposure, including claims under Swedish employment legislation and liability for unpaid social security contributions.
Sweden's updated employment rules introduce strengthened requirements around employment contract documentation, dismissal notice periods, and termination procedure compliance. The changes apply to all employers operating in Sweden regardless of corporate domicile. Foreign companies must audit existing employment contracts and collective agreement obligations by mid-2025 to avoid enforcement action.
This alert outlines the core regulatory changes, identifies the business categories and threshold criteria most directly affected, and sets out the immediate steps international companies should take.
What changed – the regulatory development and effective date
Sweden's amended employment legislation entered into force in early 2025. The changes affect three principal areas of employer obligations.
First, the rules governing employment contract documentation have been tightened. Employers must now provide written employment contracts within a shorter period after the commencement of employment. The contract must specify, among other terms, the applicable collective agreement, working hours, and remuneration structure. Previously, delays in issuing written contracts carried limited practical risk. Under the updated rules, failure to issue a compliant contract on time creates a presumption in favour of the employee in any subsequent dispute.
Second, dismissal notice periods have been revised under Sweden's updated employment legislation. The notice period that applies upon termination of an employment contract now depends more precisely on the employee's length of service, calculated to the month. Employers who apply an incorrect notice period – even by a short margin – face claims for wrongful dismissal under Swedish labour law.
Third, the termination procedure requirements have been strengthened. Swedish employment legislation has always required employers to follow a defined sequence of steps before terminating employment on grounds of redundancy or personal reasons. The amendments clarify and, in certain respects, extend those procedural requirements. An employer who fails to follow the correct termination procedure exposes itself to reinstatement orders and damages claims before Swedish labour courts.
Collective agreements negotiated through Swedish trade unions may modify some of these statutory defaults. However, the baseline statutory protections apply to all employers, including those without a collective agreement in place. Foreign companies that have historically relied on home-country practice should treat the Swedish statutory floor as the starting point.
Who is affected – threshold criteria and business categories
The updated rules apply to all employers with one or more employees working in Sweden. There is no minimum headcount threshold. This means a foreign company with a single locally engaged employee in Sweden must comply in full.
The following categories of international employer are most directly exposed:
- Foreign companies with Swedish subsidiaries or branch offices that directly employ Swedish-resident staff
- Companies posting workers to Sweden under EU or EEA posting-of-workers rules, where the posting duration meets the relevant threshold
- International groups that rely on intercompany secondment arrangements without a local employment contract
- Technology and professional services firms engaging contractors in Sweden who may, under Swedish employment legislation, be reclassified as employees
Companies in the technology, financial services, and logistics sectors are particularly exposed. Swedish courts and the relevant administrative authority have shown a consistent readiness to scrutinise contractor arrangements. A worker who lacks a genuine independent business and who works exclusively or predominantly for one principal is likely to be treated as an employee for the purposes of Swedish employment and social security legislation.
Social security obligations run alongside employment obligations. An employer who fails to correctly classify a worker also risks liability for unpaid social security contributions, which accrue from the first day of work. The Swedish Tax Agency has increased its cross-border compliance activity, and foreign employers without a Swedish tax registration should treat this as an additional risk factor.

What to do now – immediate actions and compliance timeline
The compliance deadline for aligning employment contracts with the updated documentation requirements is mid-2025. Employers who have not already begun a review of their Swedish employment arrangements should treat this as urgent.
The following immediate actions apply to international companies with Swedish operations:
- Audit all employment contracts against the updated documentation requirements. Identify any contracts that fail to specify the applicable collective agreement, remuneration structure, or notice period in the form now required by Swedish employment legislation.
- Review worker classification across contractor and secondment arrangements. Any individual who works in Sweden on a sustained basis for a single principal should be assessed against the reclassification criteria applied by Swedish courts and the Swedish Tax Agency.
- Verify notice period calculations for all staff. Recalculate dismissal notice entitlements using the revised length-of-service methodology. Update internal HR records and any employment contract templates accordingly.
- Map collective agreement obligations. Determine whether a collective agreement applies to any category of staff. Where one does, verify that its terms have been incorporated correctly into individual employment contracts and that any derogations from statute are expressly authorised by the applicable agreement.
- Confirm social security registration and contribution status. Foreign employers without a Swedish employer registration who nevertheless engage staff in Sweden should take immediate steps to regularise their position with the Swedish Tax Agency.
Companies that identify non-compliant arrangements should not defer remediation. Under Swedish employment legislation, a worker may bring a claim based on the employer's failure to issue a correct contract or to follow the correct termination procedure, even where no dismissal has yet occurred. Proactive correction reduces the exposure window significantly.
For companies managing employment across multiple European jurisdictions, it is worth noting that comparable procedural obligations exist in Portugal. Our alert on employment regulation changes in Portugal sets out the parallel requirements in that jurisdiction.
