Swedish Invoice Compliance (Fakturering)

Critical: ML chapter renumbering

Invoicing rules moved from Chapter 11 (ML 1994:200) to Chapter 17 (ML 2023:200) on 1 July 2023. Every legacy reference to "ML 11 kap" maps to ML 17 kap in current law. Always cite ML (2023:200).

Quick decision trees

Is this invoice valid?

1. Has fakturadatum?                          → ML 17:24 p.1
2. Has unique löpnummer from a series?        → ML 17:24 p.2
3. Seller's momsreg.nr (SE+10+01)?            → ML 17:24 p.3
4. Buyer's momsreg.nr (if RC or intra-EU)?    → ML 17:24 p.4
5. Full name+address, both parties?            → ML 17:24 p.5
6. Description: quantity+nature of goods/svc?  → ML 17:24 p.6
7. Delivery date (if ≠ invoice date)?          → ML 17:24 p.7
8. Tax base per rate, unit price excl VAT?     → ML 17:24 p.8
9. VAT rate stated (25/12/6%)?                 → ML 17:24 p.9
10. VAT amount in SEK?                         → ML 17:24 p.10
11. Special notations where required?
    - Reverse charge → "Omvänd betalningsskyldighet"
    - Self-billing   → "Självfakturering"
    - Exempt         → ML/Directive reference

Missing any of 1–10 = non-compliant. Missing 11 when applicable = non-compliant.
