VAT in Ireland: Registration, Rates and Filing for Small Businesses (2026)

VAT in Ireland catches many small business owners off guard. Between five different rate categories, two separate registration thresholds depending on whether you sell goods or services, bi-monthly filing obligations, and specific rules for intra-EU trade, there’s plenty of room for costly mistakes.

This guide covers what every Irish small business needs to know about VAT in 2026: when you must register, what rates apply, how to file, and which reliefs and schemes are available.

Registration Thresholds

Ireland has two VAT registration thresholds, and which one applies to you depends on what your business does:

• €37,500 — if you supply services (or a mix of goods and services where services predominate)
• €75,000 — if you supply goods

These thresholds apply to your annual turnover from taxable supplies. If you exceed the relevant threshold — or expect to exceed it in the next 12 months — you must register for VAT with Revenue.

A few important points:

• Both thresholds are based on turnover, not profit. A business with €80,000 in goods sales but only €5,000 profit is still above the threshold
• Distance selling into Ireland (e.g., an overseas e-commerce business selling to Irish consumers) has its own €10,000 EU-wide threshold under the OSS scheme. Beyond that, Irish VAT applies
• Voluntary registration is available below the thresholds. This can make sense if your customers are VAT-registered businesses (they can reclaim the VAT you charge) or if you have significant input VAT to recover — for example, during a start-up phase with heavy capital investment
• Non-established businesses: If you make taxable supplies in Ireland but have no business establishment here, you must register regardless of turnover. There’s no threshold for non-established traders

Registration is done through Revenue’s Online Service (ROS). You’ll receive a VAT number in the format IE + 7 digits + 1–2 letters (e.g., IE1234567T).

Ireland’s Five VAT Rates

Ireland has one of the more complex VAT rate structures in the EU, with five active rates:

Standard Rate: 23%

Applies to most goods and services not covered by a reduced rate or exemption. This includes professional services, most retail goods, telecommunications, and the majority of B2B transactions.

Reduced Rate: 13.5%

A broad category that covers:

• Building services (construction, renovation, repair)
• Fuel (coal, heating oil, gas for non-domestic use)
• Cleaning and maintenance services
• Short-term car hire
• Certain photographic services
• Concrete, concrete blocks, and similar building materials

Second Reduced Rate: 9%

Introduced originally as a tourism stimulus, this rate applies to:

• Restaurant and catering services (food and drink consumed on premises)
• Hotel and guest house accommodation
• Admissions to cinemas, theatres, museums, and sporting events
• Hairdressing services
• Printed newspapers and periodicals

This rate has been subject to periodic changes — it was temporarily altered during the pandemic and has been adjusted several times. Confirm the current application for your specific supplies.

Livestock Rate: 4.8%

A specialist rate applying to:

• Live cattle, sheep, pigs, deer, goats, and horses (not thoroughbred horses)
• Live greyhounds
• Certain agricultural produce

Most small businesses won’t encounter this rate unless they’re in agriculture.

Zero Rate: 0%

Zero-rated supplies are taxable but at 0%, meaning you charge no VAT to your customer but can still reclaim input VAT on related costs. Zero-rated items include:

• Most basic foodstuffs (bread, milk, meat, fruit, vegetables, tea, coffee)
• Oral medicines
• Children’s clothing and footwear
• Books (including e-books since 2020)
• Exports of goods outside Ireland
• Certain medical equipment and aids for people with disabilities

Exempt Supplies

Exempt supplies carry no VAT and you cannot recover input VAT on costs associated with them. Key exemptions include:

• Financial services (banking, insurance)
• Medical services by registered practitioners
• Education and training (by recognised bodies)
• Letting of immovable property (with some exceptions)

If your business makes both taxable and exempt supplies, you’ll need to apportion your input VAT — more on this below.

Filing Obligations

Bi-Monthly VAT Returns (VAT3)

The standard VAT filing frequency in Ireland is bi-monthly. You file a VAT3 return for each two-month period:

Returns and payments are made through ROS (Revenue Online Service). If you pay by direct debit, you get an extended deadline — typically an additional few days.

The VAT3 return summarises your:

• T1: VAT charged on sales (output VAT)
• T2: VAT on intra-Community acquisitions
• T3: Total VAT due (T1 + T2)
• T4: VAT on purchases (input VAT)
• Net amount: T3 – T4 (payable or refundable)

Plus boxes for the total value of supplies and acquisitions.

Annual Return of Trading Details (RTD)

In addition to bi-monthly returns, you must file an annual RTD after your accounting year-end. This breaks down your supplies and purchases by VAT rate, giving Revenue a detailed picture of your VAT activity. The RTD is due within 23 days of the end of your annual accounting period.

Getting the RTD wrong — or not filing it — is a common trigger for Revenue audits.

Four-Monthly or Annual Filing

If your annual VAT liability is below €3,000, you may be eligible for four-monthly or annual VAT filing. This reduces administrative burden but means you hold onto VAT for longer — which can be helpful for cash flow if you’re typically a net payer.

VIES and Intra-EU Supplies

If you sell goods or services to VAT-registered businesses in other EU member states, the VIES (VAT Information Exchange System) applies.

• Intra-Community supplies of goods: You can zero-rate these supplies provided you have the customer’s valid VAT number, the goods physically leave Ireland, and you retain proof of transport. You must report these supplies on your VIES return
• Intra-Community services: The general B2B rule is that services are taxed where the customer is established (reverse charge). You report these on VIES but do not charge Irish VAT
• VIES returns are filed monthly (by the 23rd of the following month) if you make intra-EU supplies

Always verify your customer’s VAT number through the VIES validation tool before zero-rating a supply. If the number is invalid and Revenue queries it, you may be liable for Irish VAT on the transaction.

Reverse Charge

The reverse charge mechanism shifts VAT accounting responsibility from the supplier to the customer. In Ireland, this applies to:

• Intra-EU services received from suppliers in other member states (you account for the VAT as both output and input on your return)
• Construction services under the domestic reverse charge rules (subcontractors don’t charge VAT; the principal contractor accounts for it)
• Supplies of certain goods like gas, electricity, and emission allowances

The reverse charge doesn’t change the total VAT collected by Revenue — it changes who accounts for it. But it does affect how you complete your VAT return, and errors here are common.

Cash Accounting

Under Ireland’s cash basis of accounting for VAT, you account for VAT based on when you receive payment (for sales) and when you make payment (for purchases), rather than when the invoice is issued.

You can use cash accounting if your annual turnover doesn’t exceed €2 million. This is particularly beneficial for businesses with long payment cycles — if your customers typically pay 60 or 90 days after invoice, cash accounting means you don’t have to pay VAT to Revenue before you’ve collected it from your customer.

To use cash accounting, you must notify Revenue and keep adequate records showing the date of each payment received and made.

The Two-Thirds Rule

This is an often-overlooked provision. If the cost of goods used in providing a service exceeds two-thirds of the total price charged (excluding VAT), the entire supply is treated as a supply of goods rather than a supply of services.

Why does this matter? Because the goods rate may differ from the services rate, and the registration threshold for goods (€75,000) is higher than for services (€37,500). A business that installs materials where the materials cost exceeds two-thirds of the total price could be treated as supplying goods — potentially putting them below the registration threshold or changing the applicable VAT rate.

This rule commonly applies in construction, heating installation, and similar trades where materials form a large part of the cost.

How Odiverse Automates Irish VAT

Irish VAT has enough moving parts that manual tracking — especially across multiple rates and filing obligations — is genuinely difficult to get right consistently. One miscategorised transaction at the wrong rate, one missed VIES return, or one late filing can trigger penalties or a Revenue enquiry.

Odiverse handles Irish VAT comprehensively:

• All five VAT rates: Every transaction is categorised at the correct rate — 23%, 13.5%, 9%, 4.8%, or 0% — based on the nature of the supply
• Bi-monthly VAT3 preparation: Your VAT return is calculated continuously throughout the period, so there’s no last-minute scramble before the 19th
• Annual RTD: Generated automatically from your transaction data, broken down by rate as Revenue requires
• VIES reporting: Intra-EU supplies tracked and reported with customer VAT number validation
• Reverse charge handling: Automatically applied where required, with correct entries on both the output and input sides of your return
• Cash accounting support: If you’re on the cash basis, VAT is calculated based on payment dates rather than invoice dates
• ROS-ready filing: Returns prepared in the format needed for submission through Revenue’s systems

Irish VAT compliance shouldn’t take more time than the actual work you’re doing for your clients. With Odiverse, it doesn’t.
