An e-invoice is invoice data issued and received in a structured electronic format that can be processed automatically. A PDF sent by email is generally not enough where a mandate requires structured e-invoicing. HMRC has confirmed that PDFs will not meet its definition of an e-invoice under the UK mandate.

Germany, Norway, Slovakia and the UAE all start new mandates on 1 January 2027, and Poland brings micro-entrepreneurs into KSeF on the same date. Spain introduces certified invoicing software from January 2027, with e-invoice exchange between businesses expected from October 2027. In France, smaller businesses must start issuing e-invoices from 1 September 2027.

From 1 January 2027, German businesses with prior-year turnover above EUR 800,000 must issue e-invoices to other businesses. From 1 January 2028 the obligation extends to all German businesses. All German businesses have had to be able to receive e-invoices since 1 January 2025.

From 1 January 2027, businesses with bookkeeping obligations in Norway must issue structured e-invoices to other businesses. Mandatory digital bookkeeping and e-invoice receipt follow from 1 January 2030. Tax Desk already supports VAT and VOEC compliance in Norway, and e-invoicing is on our roadmap for January 2027.

UAE e-invoicing runs through Accredited Service Providers. Businesses with revenue of AED 50 million or more go live on 1 January 2027 and needed to appoint a provider by 30 October 2026. Smaller businesses must appoint a provider by 31 March 2027 and go live on 1 July 2027.

Not necessarily. In many countries the obligation depends on establishment rather than registration. For example, businesses registered for VAT in Belgium or France but not established there are generally outside the domestic e-invoicing obligation. We can give you guidance on the requirements in the countries we support; for advice on your specific position, speak to your accountant or tax adviser.

Not yet. The UK government has confirmed that all VAT invoices between businesses and to government must be e-invoices from April 2029, exchanged over Peppol, with a detailed roadmap expected at Budget 2026. The UK is included in Tax Desk's e-invoicing coverage, so you can prepare early.

Peppol is an international network and set of standards for exchanging e-invoices through certified access points. It underpins e-invoicing in Belgium, the Netherlands, Slovakia, Australia, New Zealand and Singapore, among others, and will be used for the UK mandate. Tax Desk can connect you to any Peppol country.
