VAT Calculator Ireland: How to Calculate Irish VAT Online (2026)

If you searched for a VAT calculator Ireland tool, you need Irish rates, net-of-VAT conversion, and a clear bi-monthly set-aside — not a desktop install. A free Ireland VAT calculator in the browser applies Revenue’s 23% standard rate (plus 13.5%, 9%, and other rates) so you can check quotes and invoices before you file.

This guide explains how to calculate VAT in Ireland step by step, when registration thresholds apply (€85,000 goods / €42,500 services), and how to use FinnAccountings’ free VAT calculator for net-to-gross maths and free VAT analysis with no software download.

Enter a net (ex-VAT) amount and multiply by the Irish rate to get output VAT, or enter a gross (inc-VAT) amount and divide by 1.23 at the standard rate to extract the net. The same Ireland VAT calculator should also show reclaimable input VAT when you add purchases, so you can estimate what to set aside each bi-monthly period.

Open the free VAT calculator, leave the region on Ireland, pick the rate that matches most of your sales, and toggle Ex-VAT or Inc-VAT. Results update instantly — useful for invoices, supplier bills, and hospitality quotes still on the temporary 9% rate.

Most goods and services use the 23% standard rate. Reduced rates include 13.5% (for example fuel and certain building services), 9% (hospitality and newspapers where applicable), 4.8% livestock, and 0% for exports and qualifying zero-rated supplies. Always confirm unusual supplies with Revenue before filing.

If you sell across rates, calculate each line at the correct percentage rather than averaging. The calculator’s rate selector is designed for single-rate estimates; mixed invoices should be broken out by rate in your books.

Net of VAT means the price before VAT; gross includes VAT. At 23%, €100 net becomes €123 gross; €123 gross divided by 1.23 returns €100 net. Searchers looking for free VAT analysis or a net of VAT converter can run both conversions in the same free online tool without a VAT calculator software free download.

For return prep beyond the calculator — transaction reconciliation and ROS filing packs — see VAT Services Ireland. Pair VAT set-aside with income tax estimates using the free tax calculator for Ireland and the UK.

Irish businesses must register when rolling 12-month turnover exceeds €85,000 for goods (or €42,500 for services-only). Voluntary registration below the threshold can make sense when you reclaim significant input VAT. Once registered, most traders file bi-monthly returns with Revenue.

Use the free Ireland VAT calculator to stress-test turnover against thresholds, then start a free trial if you want FinnAccountings to organise bookkeeping and VAT prep drafts with Chartered Accountant insight before you or your Chartered Accountant (Ireland) adviser signs off filings.

Open the free VAT calculator for live rate maths, review VAT Services Ireland for return workflows, and use the tax calculator when you need USC and PRSI estimates beside VAT. Hospitality traders on the temporary 9% rate should also read our July 2026 hospitality VAT update.
