Invoice Generator for Ireland

If you are not registered for VAT, your invoice is a commercial document: who supplied what, to whom, for how much, and by when it should be paid. Keep a copy as part of your business records.

Once you are an accountable person registered for VAT, the invoice becomes the basis of your VAT liability and your customer's right to reclaim the VAT charged. Revenue prescribes exactly what it must contain, and a missing VAT number or rate breakdown can cost your customer their deduction.

Timing matters in Ireland as much as content. Revenue's rule is that a VAT invoice issues within 15 days of the end of the month in which the supply was made, with separate treatment for payments received in advance.

Revenue requires a unique sequential number on a VAT invoice. A straight run — 0001, 0002, 0003 — is the simplest compliant scheme, and a dated variant such as 2026-001 works equally well provided a number never repeats.

Sequences may be based on one or more series, so a separate run per company or per branch is acceptable as long as each full number is unique and the series is explainable.

If an invoice is wrong, do not delete it or reuse the number. Issue a credit note referencing the original and keep both documents in the sequence — that is what makes your VAT records reconcilable if Revenue asks.

An Irish VAT invoice shows both the date of issue and the date the goods or services were supplied, because they determine different things: the issue date governs the 15-day deadline, and the supply date governs which VAT period the supply falls into.

Thirty days is the common commercial default in Ireland. Public bodies operate prompt payment arrangements and many pay considerably faster, while smaller suppliers often work on 14-day terms.

VAT in Ireland is administered by Revenue. As set out on Revenue's current VAT rates table, the standard rate is 23%, the reduced rate is 13.5%, the second reduced rate is 9%, and a livestock rate of 4.8% applies to specified supplies. Which rate applies depends on what you supply, not on who you are — Revenue publishes a searchable rates database for individual goods and services.

Rates and their scope move with each Finance Act. This page was last reviewed in September 2026; before applying a rate to an unusual supply, confirm it in Revenue's VAT rates search rather than relying on a general article.

Registration is obligatory once turnover passes the relevant threshold, and Revenue sets different thresholds for services, for goods, and for intra-Community distance sales and cross-border digital services. Below the threshold you may elect to register — often worthwhile if your customers are themselves VAT registered and you carry significant input VAT.

Irish invoices are issued in euro, written as €1,250.00, with a comma for thousands and a full stop for cents. The symbol goes before the figure.

You may invoice in another currency where that is what you agreed, but the VAT amount has to be accounted for in euro. Show the euro VAT figure on the invoice so your customer and your own bookkeeping agree on the number.

For payment, IBAN and BIC are what an Irish or European payer needs. SEPA transfers within the euro area are routine, so quoting both alongside a payment reference removes the usual back-and-forth.

Most Irish invoicing questions are answered directly by Revenue's own guidance, which is unusually clear. An accountant earns the fee where the answer depends on your circumstances: approaching a registration threshold, choosing a VAT accounting basis, or working out the treatment of a cross-border supply.

Construction and property businesses should take advice early, because relevant contracts tax and the construction reverse charge together change both what you invoice and what you actually receive.
