Tax, coordination numbers and the economic employer rule in Sweden

The work permit settles the right to work, not the payroll. Skatteverket, the Swedish Tax Agency, assigns a coordination number to workers who have no personal identity number, and that number is required for tax deduction and for the payroll return. Since 1 January 2021 an economic employer concept also applies, so the 183 day rule does not cover hired labour supplied to a Swedish client.

The coordination number everything else hangs on

A worker who will work in Sweden but is not registered as resident receives no personal identity number. Skatteverket then assigns a coordination number, an identity designation that serves the same function in the systems. Without it you can neither make a correct tax deduction nor report the person in the payroll return, and the payroll run stalls on a line with no identity.

The sequence is what usually surprises employers. The permit comes first, then entry, then the identity check at Skatteverket, and only then the number. The worker normally has to attend a service office in person with a passport, because Skatteverket verifies identity before assigning the number. Plan that step for after arrival rather than before it, and put it in the mobilisation plan alongside banking and housing.

The application for special income tax or for ordinary A tax belongs to the same visit. Where the person has limited tax liability and is taxed under SINK, that is an application to Skatteverket; where the person has unlimited tax liability, ordinary A tax and the tax table apply. The choice sets the size of the deduction on the first payslip, and an error here is corrected through an amended payroll return rather than through an adjustment in the next payroll run.

The economic employer rule that changed hired labour

Before 2021 a foreign employer could rely on the 183 day rule: if the person worked in Sweden for fewer than 183 days in a twelve month period and the salary was paid by the foreign employer, the income was not taxed in Sweden. Since 1 January 2021 Skatteverket applies an economic employer concept, and the 183 day rule does not apply where the arrangement is hired labour supplied to a Swedish client.

The practical difference is this. Where the worker works under the Swedish client's direction, inside that client's operation and at its risk, the client is treated as the economic employer. The income is then taxed in Sweden from day one, even when the salary is paid from abroad and even when the assignment lasts six weeks. Where the foreign company instead performs a defined contract with its own supervision and its own responsibility for the result, that is not hired labour, and the older assessment may still hold. The line is drawn by how the work is actually directed, not by the heading on the contract.

A foreign employer with no permanent establishment in Sweden must, according to Skatteverket, register as an employer here once tax deductions are to be made. Registration is therefore not tied to an office or a branch; it is triggered by the deduction obligation. An employer who discovers this three months into an assignment has to correct backwards.

The monthly payroll return

The individual payroll return, known as AGI, must be filed every month and must report each employee separately with the remuneration paid and the tax deducted. The monthly rhythm is what makes the schedule tight. A coordination number that arrives late does not postpone the return, it only makes the reporting harder to get right on time.

The return covers each calendar month and the payments made in it, so an employee who starts on the twenty seventh still belongs in that month's AGI. Skatteverket uses the individual data to establish the worker's own taxation, which means a coordination number mistyped in the payroll system carries all the way through to the person's own tax return. Check the number against the decision from Skatteverket rather than against a photographed sheet of paper.

A normal file runs in this order. Permit from Migrationsverket, entry, the visit to Skatteverket for identity check and coordination number, the decision on SINK or A tax, the first payroll run, then the AGI for that month. The cost at Skatteverket is mainly administrative, while the real cost sits in late filing charges and in corrections to returns filed under the wrong identity or the wrong tax form.

If you are sending staff here on assignment instead of employing them locally, the notification rules in posting workers to Sweden apply first. The wider logistics of moving a non EU hire are in the relocation chain for a non EU hire, and the division of duties between employer and client is set out in the employer compliance chain.

The administrative track after the permit is short but strictly ordered, and most trouble comes from taking the steps out of sequence. Book the identity check at Skatteverket in the week of arrival, settle the tax form before the first payroll run, and decide before the assignment starts whether the arrangement is hired labour or contract work.
