12 November is the last day to pay August kvarskatt

Twelve November is the last day to have kvarskatt booked on the tax account for taxpayers who received their final tax notice (besked om slutlig skatt) in AugustSkatteverket. The amount and the due date appear on the notice itself, and the full balance must be booked on the skattekonto by that dateSkatteverket. Payments can be split, but splitting does not extend the due date.

Payment runs through Swish or Skatteverket's bankgiro 5050-1055 with the OCR number from Mina sidor or the Skattekonto and OCR-beräkning services. Swish requires at least 10 kronor and at most 40 000 kronor per day; a Swish payment is booked the same day but can take up to three banking days to show on the account. An internet-bank transfer is booked at the earliest the next banking day. Cash is not accepted.

Interest makes early payment worthwhile for larger balances. On kvarskatt above 30 000 kronor, cost interest (kostnadsränta) on the part exceeding 30 000 kronor runs from 13 February 2026; on balances of at most 30 000 kronor it runs from 5 May 2026. Interest accrues day by day at the low cost-interest rate until the payment is booked, so paying before the due date shortens the accrual period. The published payment table pairs an August 2026 final notice with payment by 12 November 2026Skatteverket, alongside April to 13 July, June to 14 September and December to 12 March 2027.

The declaration hub (Deklaration, income year 2025) now leads with this 12 November payment dateSkatteverket. It replaces the previous banner, which named 9 November as the last day to apply for helårsjämkning with the e-service open from 1 October. The standing filing frame is unchanged: declare in Inkomstdeklaration 1 with e-legitimation, with 4 May as the last filing day for those without an extension. Approving without changes can be done in the newer service with e-legitimation or codes, while changes or additions require e-legitimation.

The same edit adds a new sold-your-home blockSkatteverket. Anyone who has sold a home can enter and save the sale details immediately after the sale and get help calculating deductions for renovations. The sale itself is declared the year after the purchase contract was signedSkatteverket, for every housing type including bostadsrätt, villa and fritidshus. Deductible items include selling expenses such as brokerage, inspection and homestyling, certain purchase costs such as lagfart and pantbrev, and qualifying renovations. The renovation rules distinguish grundförbättringar — new construction, extensions, converted layouts or equipment not previously present, deductible in full whenever made during ownership — from replacements or non-layout renovations, deductible only in part. A dedicated service helps classify the work and report it correctly.

One sentence disappeared from the hub: the statement that travel deductions for income year 2026 (declaration 2027) are granted only for the part of commuting and work-travel costs exceeding 15 000 kronorSkatteverket no longer appears on this pageSkatteverket. Skatteverket's Belopp och procent tables for 2026 list the threshold as 15 000 kronorSkatteverket, raised from 11 000 kronor for income year 2025.

Standard declaration duties continue to apply. Information in the return must be checked against supporting documents, expense deductions must be provable afterwards, and all supporting material must be kept for six years — for example, documents from a 2025 home sale are kept through the end of 2031. Errors are corrected first through the information provider and otherwise by amending in Inkomstdeklaration 1 or filing a new return.

The legal basis is Skatteverket's Deklaration hub with its Betala kvarskatt, Försäljning av privatbostad and Avdrag för renoveringar och nybyggnad guidance and the Belopp och procent tables for income year 2026.
