Registering a company for VAT in Ireland is a Revenue process separate from incorporation at the Companies Registration Office. A company needs a CRO number first, then must assess whether its taxable activity requires VAT registration, makes voluntary registration useful, or falls under a cross-border rule that needs specialist attention.
This guide explains the registration process, thresholds, ROS, VAT rates, returns, evidence and common mistakes. It is general information, not tax advice. The correct treatment depends on what the company sells, where its customers are, where suppliers are established and how the business operates.
Quick answer
Incorporate the company, obtain its CRO number, identify its taxable supplies and expected turnover, then apply through ROS or a tax agent using the Revenue route that fits the company. Do not charge Irish VAT or display a VAT number before registration is confirmed. VAT registration is separate from Corporation Tax and does not guarantee approval.
Does Every Irish Company Need VAT Registration?
No. A company does not need a VAT number simply because it has been incorporated. VAT depends on whether it makes taxable supplies, the level of turnover, whether it receives or makes cross-border supplies and whether a special rule applies. A business carrying out only exempt or non-taxable activities may not be entitled to register in the ordinary way.
A company should document the decision. Record the supplies, expected start date, projected turnover, customer locations and the reason for registering or waiting. Revisit the decision when the business adds a new product, enters an EU market, imports goods or begins receiving services from abroad.
Irish VAT Registration Thresholds
Revenue currently lists these principal thresholds, measured by the value of relevant turnover rather than profit:
| Situation | Principal threshold | Important note |
|---|---|---|
| Services only | EUR42,500 | Check whether the supplies are taxable services |
| Goods | EUR85,000 | Special goods categories can differ |
| 90% or more goods turnover | EUR85,000 | Apply the current Revenue calculation |
| EU acquisitions and distance sales | Special thresholds | Cross-border rules and OSS may apply |
Thresholds are not a complete VAT test. A business can have an obligation because of services received from abroad, intra-Community acquisitions, distance sales or another special rule. Use Revenue's current thresholds rather than an old blog post or a number copied from an invoice.
When Voluntary VAT Registration May Make Sense
A company below the compulsory threshold may be able to elect to register. This can be useful for a genuine taxable business with significant VAT-bearing start-up costs, mainly VAT-registered business customers or a near-term plan to exceed the threshold. It can be less attractive for a consumer-facing business that cannot easily pass VAT through its prices.
Voluntary registration is not just a credibility badge. It can create VAT invoicing, return, evidence and payment obligations. Consider expected margin, customer pricing, input VAT, mixed supplies and the administrative cost before applying.
Step-by-Step: How to Register a Company for VAT
- Incorporate the company and receive its Certificate of Incorporation and CRO number.
- Describe the actual business activity and confirm the expected trading start date.
- Identify taxable goods or services, turnover and customer and supplier locations.
- Check compulsory, voluntary and cross-border VAT rules with current Revenue guidance.
- Prepare the company, director, bank, agent, turnover and activity information.
- Apply through ROS, through a tax agent, or through the Revenue route that applies to the company.
- Respond promptly if Revenue requests contracts, invoices, website or trading evidence.
- Use the VAT number and charge VAT only once registration and its effective date are confirmed.
- Set up VAT invoice templates, bookkeeping and return reminders.
The tax registration service can support VAT and related Revenue registrations after incorporation. Keep the CRO, RBO and Revenue responsibilities in separate compliance records.
ROS, Tax Agents and Application Routes
Revenue Online Service (ROS) is used for many business tax registrations, returns and payments. If an accountant or tax agent represents the company, the agent can generally submit an online registration through ROS. Protect the company's ROS administrator access and digital certificate, and agree who is responsible for each return.
A company that cannot use the standard online route should check the current Revenue instructions and form. Revenue identifies different routes for resident companies, foreign companies and companies without an agent. Do not select a form solely because its name appears in an old guide.
Evidence Revenue May Ask For
A recently incorporated company may not have a long trading history. That does not make VAT registration impossible, but the application should explain the commercial plan clearly. Prepare:
- Certificate of Incorporation and CRO number.
- Business activity, website and expected trading date.
- Expected turnover and a description of the taxable supplies.
- Customer or supplier contracts, purchase orders and invoices where available.
- Business address, bank information and director or tax-agent details.
- Cross-border supply information and customer VAT numbers where relevant.
VAT Rates and Invoicing
Ireland has a standard VAT rate and reduced, zero-rated and exempt treatments for particular supplies. Apply the rate for the product or service, not the rate that seems most common in your industry. A VAT invoice normally needs the company's legal details, VAT number, invoice date, sequential number, customer details, description, net amount, rate and VAT amount, subject to the applicable rules.
Do not add VAT to an invoice merely because a customer asks for it. First confirm that the company is registered, the supply is taxable and the effective date and place-of-supply rules support the charge.
VAT Returns, Payments and Records
VAT registration creates ongoing work. The standard VAT period is generally bi-monthly, although Revenue may permit another arrangement depending on the company. Returns and payments are usually made electronically through ROS. The company must keep valid VAT evidence, reconcile sales and purchases, and separate input VAT from costs that are not recoverable.
Keep invoices, credit notes, import and export records, customer VAT numbers, bank statements, purchase receipts and evidence for any reverse-charge or zero-rate treatment. Retain records for the required period and make the bookkeeping process part of the company's ordinary operations.

Online Sales, EU Customers and Non-Resident Companies
Online businesses need to separate Irish B2B, Irish consumer, EU B2B, EU consumer and non-EU transactions. EU consumer distance sales can bring the One Stop Shop (OSS) into play. EU B2B services may involve reverse charge and VIES checks. Imports, digital services and goods stored in another country have their own rules.
A non-resident company does not automatically need an Irish VAT number merely because it forms an Irish company or has an Irish registered office. It should assess its Irish taxable supplies, establishment, customer location, stock and contracts. Revenue may ask for evidence of the actual activity and the correct route can differ from an Irish-resident company.
Common VAT Registration Mistakes
- Using outdated thresholds or treating turnover as profit.
- Assuming CRO incorporation automatically creates VAT registration.
- Registering without understanding customer pricing and return obligations.
- Charging VAT or displaying a VAT number before confirmation.
- Using the wrong VAT rate or treating exempt supplies as zero-rated.
- Ignoring services received from abroad, EU acquisitions or OSS.
- Failing to keep valid invoices and evidence for input VAT recovery.
- Assuming a company bank account, Irish address or website guarantees VAT approval.
Frequently Asked Questions
How do I register a company for VAT in Ireland?
After incorporation, obtain the CRO number and prepare the company’s activity, turnover, customer, supplier and director details. Register through ROS, through a tax agent, or through the current Revenue application route for the company.

No. VAT and Corporation Tax are separate Revenue registrations. A company may need one, both, or other registrations such as employer PAYE/PRSI or RCT depending on its activity.
