Public sector only
Mandatory for B2G since 1 January 2020 — and a PDF does not count.
| 1 Jan 2020 | B2G e-invoicing mandatory for all central and sub-central authorities |
| — | B2B and B2C remain voluntary, on the same Peppol infrastructure |
Format: Peppol BIS Billing 3.0 with the Icelandic CIUS ÍST TS 236
Transmission: Peppol
Iceland implemented EU Directive 2014/55/EU in full: since 1 January 2020 every invoice to the public sector must be a structured e-invoice, and a PDF is explicitly not accepted — which is the mistake that actually gets suppliers rejected, because emailing a PDF feels electronic. The national CIUS is ÍST TS 236, a narrowing of Peppol BIS Billing 3.0 rather than a separate format, so a valid Peppol invoice is most of the way there. This validator checks the 10 Icelandic IS-R rules automatically when the seller is Icelandic — you do not need to select anything. B2B and B2C are voluntary and run on the same Peppol network.

The Peppol profile also applies this country's own rules, and they are switched on automatically from the seller's country — no extra parameter. See the 10 Iceland rules this validator checks →
