2026 calendar

What's due, and when?

Grouped by month. The recurring AGI/arbetsgivaravgifter deadline is expanded into each 2026 instance so nothing is hiding behind a "monthly" label.

Arbetsgivardeklaration (AGI) och betalning av arbetsgivaravgifter

AGIMonthly

Arbetsgivardeklaration på individnivå (AGI) is filed with Skatteverket, and the skatteavdrag and arbetsgivaravgifter on the previous month's payroll are paid, by the 17th — the 12th as a general rule, the 17th in January and August. If the date falls on a weekend or a public holiday it moves to the next banking day. Employers with turnover above 40 MSEK file on a different schedule; check your own redovisningsperiod with Skatteverket.

31 Mar

Intjänandeåret 2025–2026 ends

Annual leave

The intjänandeår runs 1 April–31 March (3 §). This date fixes the number of betalda semesterdagar for the semesterår starting the following day — the reference point every downstream leave-accrual number depends on.

31 Mar

Annual review: sparade semesterdagar approaching the five-year limit

Annual leave

A sparad semesterdag must be scheduled within five years of the end of the semesterår in which it was saved (18 § andra stycket); 20 § andra stycket allows a deferral into the sixth year by agreement where taking it in the fifth would cause betydande olägenhet. The end of the semesterår is the natural point to review which saved days are approaching the limit.

1 Apr

New semesterår and intjänandeår begin

Annual leave

The semesterår and the next intjänandeår both run 1 April–31 March, not the calendar year (3 §). Getting this start date wrong is the single most common source of miscalculated betalda semesterdagar.

30 Apr

Practical last day to give besked om huvudsemester (derived)

Annual leave

Semesterlagen requires besked om semesterns förläggning at least two months before the leave starts (11 §). Measured against a huvudsemester beginning in July, that makes the end of April the last reasonable day to give notice — for a June start the equivalent date is the end of March. This entry is derived from the two-month rule, not a statutory date in its own right.

Operator angle & related

The AGI deadline above repeats every month without fail, and it's the one most likely to slip when a due date moves around a public holiday or a founder is doing payroll manually alongside everything else. The annual-leave dates matter less as deadlines and more as the reference points your semester accrual depends on — get the intjänandeår start date wrong and every betalda-semesterdagar calculation downstream is wrong too.

Taito.ai keeps the leave and attendance records these deadlines depend on — accrual balances, absence history, and the underlying data — in one place, so the numbers behind these dates are ready when you need them.
