Ireland e-invoicing
No Ireland data file exists anywhere in this repository — no country policy, no identifiers, no tax system, no transmission channel. Nothing on this page is implemented. It is here so that someone who wants Ireland support knows what adding it would involve. The countries Invoicerr does cover are listed in the country directory.
Ireland has required public bodies to receive e-invoices since 2019, under EU Directive 2014/55/EU, delivered over the Peppol network to buyers registered with Revenue (the Revenue Commissioners). B2B e-invoicing is voluntary today, but Revenue announced a phased domestic mandate in October 2025 that would extend it to all VAT-registered businesses.
What supporting Ireland would involve
| System | Peppol e-invoicing for Ireland's public-sector buyers, under EU Directive 2014/55/EU |
| Authority | Revenue Commissioners (Revenue) |
| Format | EN 16931 (Peppol BIS). This repository already builds and validates it (formats/peppol-bis-provider.ts, formats/ubl-provider.ts), so the format would not have to be written from scratch. |
| Transmission | Peppol Access Point. The Peppol transport was removed from this repository on 2026-09-15 for want of a real Access Point account, so one would have to be built. |
Carried over from an earlier research pass in this repository's own history, and never checked against a primary source. Leads, not facts — confirm every line before writing it into a data file.
- B2G e-invoice receiving has been mandatory since April 2019 for central bodies, and since April 2020 for all public entities.
- Revenue's October 2025 roadmap phases in a domestic B2B mandate between 2028 and 2030, starting with large VAT-registered businesses.
- Future reporting is expected to tie into VIES, the EU's cross-border VAT information exchange.
Which catalogues a contributor would add
Adding a country is data, not code. Adding a country is the procedure and the contract each file has to satisfy; this is only the shopping list for Ireland.
country-policy/data/ie.json— which document actions Ireland allows. Start here: without this file every action is refused with a 403, naming the country.country-identifiers/data/ie.json— which national identifier a party must carry.tax/tax-systems/data/ie.jsonandvat-rates/data/ie.json— the tax kind, and the rate ladder offered on an invoice line.correction-routes/data/ie.json— all eleven canonical correction routes,unverifiedwhere unresearched, never omitted.b2g-routing/data/ie.json— the channel and format an Irish public buyer requires.transports/channel-policy/data/ie.json— whether a channel is legally required of a seller established in Ireland, and from what date.archive/retention/data/ie.json— how long an archived document is kept, and what the duration is counted from.
Add mentions/, content-requirements/, country-fields/, reporting/ and
domestic-reverse-charge/ only where the law actually gives them content.
Data alone will not finish the job here: the Peppol network is a transmission channel this repository does not implement, which is code, not a JSON file — see When a country needs more than a file.
Want Ireland supported?
Check the open compliance issues first. If there is no issue for Ireland, open one and name which of the files above you need — a request that names one mechanism is far more actionable than "please add Ireland".
