EU · NemHandel / Peppol
E-invoicing to public authorities has run over Nemhandel since 2005. The Bookkeeping Act's digital-bookkeeping duty is fully phased in (last cohort 1 Jan 2026): registered systems must be able to send and receive OIOUBL/Peppol BIS e-invoices, but B2B sending remains voluntary. A draft order in force 1 Jan 2027 makes Nemhandel enrolment the default and e-invoicing the first sending option.

Next phase deadline
Default e-invoice enrolment from 1 Jan 2027
Three questions. The fixed-establishment rule is where most foreign businesses get it wrong.
Is your business established in Denmark (registered office, branch or fixed establishment)?
Do you make intra-EU B2B supplies involving Denmark?
Denmark: likely outside the issuing mandate — watch e-reporting / cross-border
Denmark has no issuing mandate for anyone and no e-reporting. If you use a Danish registered bookkeeping system you will be enrolled to receive e-invoices from 2027 unless you opt out. Whether a VAT-only registration brings you under the Bookkeeping Act depends on your Danish activity and turnover – check with an adviser.
Not in scope for Denmark
With no establishment and no registration or trade in Denmark, the mandate doesn't apply to you today. Revisit this if you open a branch, warehouse or start supplying into Denmark.
Denmark: no domestic mandate yet — ViDA applies from July 2030
Denmark has no confirmed domestic B2B mandate, but ViDA makes structured e-invoicing and digital reporting mandatory for intra-EU B2B from 1 July 2030. Build EN 16931 / Peppol capability now.
No e-invoicing mandate applies in Denmark today
No domestic B2B e-invoicing mandate applies in Denmark (B2G has required it since 2005). Watch the 1 Jan 2027 default-enrolment order and the 2030 ViDA date.

Scope
All businesses under the Bookkeeping Act must keep books in a digital system (annual-report entities from 1 Jul 2024/1 Jan 2025; others with net turnover above DKK 300,000 in two consecutive years from 1 Jan 2026). Systems must support OIOUBL and Peppol BIS; no obligation to transmit B2B invoices electronically. From 1 Jan 2027 (draft order, consultation closed 17 Aug 2026) providers enrol users in Nemhandelsregistret unless they opt out within four weeks, and SAF-T 2.0 export becomes mandatory. OIOUBL retires in favour of Nemhandel BIS 4 (Peppol PINT) by mid-2029.
Fines are for not using a compliant digital bookkeeping system or not retaining records, scaled by turnover – DKK 10,000–25,000 for minor breaches (turnover under DKK 10m) up to DKK 1–1.5m for serious breaches (turnover above DKK 100m). No duty to send e-invoices exists, and no e-invoice-specific penalty.
