Sweden VAT Return (Momsdeklaration) — Skatteverket Filing

Confirm the client's momsregistreringsnummer (SE + 12 digits), organisationsnummer, and filing frequency. Skatteverket assigns monthly filing for turnover above SEK 40M, quarterly for SEK 1M–40M, and annual for below SEK 1M. Identify the exact period (e.g. Q1 2026: 1 Jan–31 Mar), the due date, and whether the client has any carry-forward input VAT credit from the previous period.

Classify every transaction in the period into the correct Momsdeklaration ruta using the Sweden VAT skill supplier library and rate rules. Domestic sales map to ruta 05–12 (25%/12%/6%); intra-EU B2B goods dispatched to ruta 35, EU services supplied to ruta 36, exports to ruta 37; EU goods acquisitions to ruta 20/30, EU services received to ruta 21/30, non-EU services received to ruta 23/30, domestic construction reverse charge to ruta 24/30. Flag blocked-input items (representation above SEK 300/person excl. VAT, mixed-use passenger cars, private use) for Tier-2 review.

Aggregate the classified transactions into the official ruta boxes. Ruta 05 = total sales excl. VAT (sum of 06+07+08). Output VAT totals in ruta 10 (25%), 11 (12%), 12 (6%). Reverse-charge output VAT all flows into ruta 30. Input VAT (all rates combined) in ruta 48. Compute ruta 49 = total output VAT (ruta 30 + 10 + 11 + 12) minus ruta 48. If ruta 49 is negative, the return shows a repayment claim (återbetalning av moms). Apply any carry-forward credit from Phase 1.

The preparer reviews the completed Momsdeklaration for arithmetic accuracy, blocked-input compliance, VIES verification for any EU B2B supplies, and consistency with the prior period. Once signed off, the return is e-filed on Skatteverket Mina sidor (login with BankID or e-legitimation) before the statutory deadline. The resulting confirmation page (kvittens) and any skattekonto statement showing the debit or credit are saved.
