Sweden Employer Payroll — Arbetsgivardeklaration & Arbetsgivaravgifter

Confirm the employer holds a valid F-skatt or A-skatt registration with Skatteverket and is enrolled as an employer (arbetsgivare). Establish the correct tax table (skattetabell) for each employee based on their municipality of residence, and identify any employees subject to special rules: SINK flat 22.5% for non-residents, reduced 10.21% rate for employees aged 67+, or the temporary youth discount (20.81%) for employees born 2003–2007 effective 1 April 2026.

For each employee, compute gross pay including grundlön, övertidsersättning, OB-tillägg, and any taxable benefits (förmånsvärde — company car, subsidised meals, etc.). Look up the preliminary income tax (preliminärskatt) from the applicable skattetabell. Calculate employer social contributions (arbetsgivaravgifter) at 31.42% of total gross including förmånsvärde, applying reduced rates where eligible. Compute occupational pension contributions (tjänstepension via ITP1/ITP2 or SAF-LO) and the special payroll tax on pension costs (SLP at 24.26%).

Issue a lönespecifikation to each employee for the pay period, typically paid on the 25th of the month. The payslip must show gross salary (grundlön), any supplements (övertid, OB-tillägg), taxable benefits (förmånsvärde), preliminary tax withheld (preliminärskatt), and net salary (nettolön). Pension deductions and year-to-date totals are standard per most kollektivavtal. Ensure holiday pay accrual (semesterlön) is tracked — 12% of gross for hourly workers, or semestertillägg for salaried staff.

Submit the monthly arbetsgivardeklaration to Skatteverket, including per-employee individuppgifter (gross salary, förmånsvärde, and preliminärskatt per person) and the aggregated employer contribution amounts. The deadline is the 12th of the following month (extended to the 17th for January and August). Pay the total of preliminärskatt withheld plus arbetsgivaravgifter to the employer's skattekonto on the same deadline. Late filing incurs SEK 625/month penalty (up to SEK 6,250).

At calendar year-end, prepare and submit the annual kontrolluppgift (KU10 for employment income, KU13/KU14 for certain other income) to Skatteverket by 31 January. The KU10 reports each employee's annual taxable income, förmånsvärde, and total preliminary tax withheld, and feeds directly into their pre-completed inkomstdeklaration 1. Reconcile total arbetsgivaravgifter paid during the year against the annual summary. Send each employee their copy of the KU10 in February so they can review their pre-completed tax return (March–May filing window).
