What must be on a Dutch freelancer invoice? (EN checklist)

Updated 2026-10-23

General information, not tax or legal advice. Rules and rates change; check the Belastingdienst website or an adviser for your situation.

A Dutch invoice must include, among other things:

• A unique, sequential invoice number
• Invoice date and date of supply
• Your name, address and VAT identification number (btw-id)
• Your KvK (Chamber of Commerce) number
• Client name and address
• Description and quantity of the work
• Amount excluding VAT, VAT rate and VAT amount per rate
• For EU business clients under reverse charge: the client's VAT number and the text "VAT reverse-charged" (btw verlegd)

Sequential numbering is the one people break most often; use an automatic counter.
