If you are considering how to verify the VAT number on an Irish ready-made company before purchase, you need more than a basic online search. A live VAT number is not enough on its own: you also need to confirm the registration history is clean, the scheme type matches your trading needs, and Revenue has no outstanding issues. This guide covers the full verification process using ROS, VIES, and Revenue eRegistration, so you can complete your checks in under ten minutes.
Why VAT Verification Matters Before You Buy
A VAT-registered Irish ready-made company carries a premium of €7,000 over a plain shelf company (€12,000 versus €5,000). That premium reflects years of clean VAT registration history and immediate EU trading capability. Before committing, you need to verify that the VAT number is live, the history is clean, and the registration covers the right scheme for your business operations.
If you inherit a company with a suspended or limited VAT registration, Revenue may require a fresh VAT application, which typically takes 4 to 12 weeks. That wipes out the speed advantage you paid for.
First Check: Does the Company Have a VAT Number at All?
Not all shelf companies in Ireland have VAT numbers. VAT registration is handled by Revenue, not the Companies Registration Office: incorporating a company with the CRO creates the legal entity, but it does not automatically create a VAT registration. There are therefore two distinct types of ready-made company on the market:
- Plain shelf company – incorporated with the CRO, clean history, but not registered for VAT with Revenue (€5,000)
- VAT-registered shelf company – incorporated and Revenue VAT-registered, with a live VAT number verifiable on VIES and ROS eRegistration (€12,000)
If a seller does not explicitly state that a shelf company is VAT-registered, assume it is not. Sellers who offer VAT-registered inventory must plan ahead, applying for VAT registration at the time of formation and holding the company while Revenue completes its review. That advance investment in time and compliance work is what justifies the premium, and it also explains why not every formation agent offers VAT-registered companies and why availability can be limited.
5-Minute Live Verification Using Public Tools
Start with two public tools that require no login and give an instant result.
Step 1 – VIES check (EU-wide). Open the EU VIES tool at ec.europa.eu/taxation_customs/vies. Enter the company’s VAT number with the IE prefix (for example, IE1234567T). A “valid” result confirms the number exists in the EU VAT database and is active for intra-EU transactions.
Step 2 – Revenue eRegistration (Irish-specific). On Revenue’s ROS portal (ros.ie), use the eRegistration enquiry function. This shows the VAT registration date, the registered VAT scheme, and whether the registration is active or suspended.
Step 3 – Cross-reference registration date. Note the original VAT registration date. A registration date predating the company’s transfer to you confirms the history you are buying. A very recent registration (under 60 days) may indicate Revenue is still reviewing the account.
Deeper Checks via Tax Clearance Certificate
A Tax Clearance Certificate (TCC) from Revenue confirms the company has no outstanding tax liabilities across all tax heads, including VAT, corporation tax, and employer PAYE/PRSI. A reputable seller of VAT-registered ready-made companies should be able to provide a current TCC or request one via ROS on your behalf prior to the sale.
If the seller cannot produce a TCC, treat this as a red flag. An outstanding VAT debt transfers with the company and becomes your liability post-purchase.
Verifying Intra-EU Dispatch Capability
Not all Irish VAT registrations automatically enable intra-EU dispatches. You need to confirm the company is registered for intra-community supplies, which allows zero-rated B2B sales to VAT-registered businesses in other EU member states.
On VIES, a “valid” result confirms the company is listed in the EU-wide database and can issue and receive intra-EU supplies. If VIES returns “valid – not registered for intra-Community transactions,” the company needs a supplementary update through Revenue before it can issue zero-rated invoices to EU buyers.
For non-EU trade, check whether an EORI number is attached. EORI numbers are issued by Revenue via ROS and are separate from the VAT number, but essential for importing or exporting goods through Irish customs. See our guide on what an EORI number is and why you need it for the full picture.
Red Flags During VAT Verification
Stop and seek clarification from the seller if any of the following appear during your checks:
- VIES returns “invalid” for the VAT number
- Revenue eRegistration shows a suspended, deregistered, or cancelled status
- The VAT registration date is within the last 60 days (Revenue review may be pending)
- The seller cannot produce a Tax Clearance Certificate
- The VAT scheme type does not match your intended trading activity
- Outstanding VAT3 returns are overdue on the company’s Revenue record
Any of these issues requires resolution before you proceed with the purchase.
What a Reputable Seller Provides as Proof of VAT Cleanliness
A professional company formation agent selling a VAT-registered ready-made Irish company should supply, on request: a current Tax Clearance Certificate, a VIES screenshot confirming “valid” status, the Revenue eRegistration confirmation showing the VAT registration date, and confirmation of the VAT scheme type. At Chern & Co, all VAT-registered ready-made companies are verified before listing at €12,000 flat.
VAT Schemes: IOSS and OSS Considerations
If your business sells goods or digital services to EU consumers, ask whether the company is enrolled in the One-Stop Shop (OSS) or Import One-Stop Shop (IOSS) schemes. These schemes let you report EU VAT through a single Irish return rather than registering in each member state. If the company you are buying is not enrolled, you can apply post-purchase via ROS.

If the Company Has No VAT Number: The TR2 Route
If you buy a plain shelf company and need VAT registration, you apply through Revenue’s ROS eRegistration portal by completing a TR2 form (for companies), providing details of the business activity, expected turnover, and trading address. Revenue reviews the application, may request additional documentation, and processing typically takes 4 to 12 weeks. During the review period, the company cannot issue VAT invoices or reclaim VAT on purchases – this is the operational gap that a VAT-registered shelf company eliminates.
The 2026 Irish VAT registration thresholds are €85,000 for businesses supplying goods and €42,500 for businesses supplying services. Registration is compulsory if turnover in any continuous 12-month period exceeds, or is expected to exceed, the relevant threshold, and voluntary registration is available below it. Ireland’s standard VAT rate is 23%, with reduced rates of 13.5% and 9% applying to specific categories. These thresholds and rates apply identically whether you buy a VAT-registered company or self-register. For the self-registration walkthrough, see how to register for VAT in Ireland in 4 steps.
Frequently Asked Questions
How do I check if an Irish VAT number is valid?
Use the EU VIES tool at ec.europa.eu/taxation_customs/vies. Enter the VAT number with the IE prefix and the system returns a “valid” or “invalid” status. For Irish-specific details including registration date and scheme type, use Revenue’s eRegistration enquiry on ROS.
What does it mean if VIES shows “invalid” for an Irish VAT number?
An “invalid” VIES result means the VAT number is either not active, has been deregistered, or has not yet been added to the EU-wide database. For a ready-made company purchase, an invalid VIES result is a serious red flag that requires investigation before proceeding.
Can I verify a Tax Clearance Certificate myself?
Yes. Revenue provides an online TCC verification service. The seller can share the certificate number and you can independently confirm its validity at revenue.ie. A valid TCC confirms no outstanding liabilities across all tax heads.
Why is a VAT-registered ready-made company more expensive than a plain shelf company?
The price difference between a VAT-registered ready-made company (€12,000) and a plain shelf company (€5,000) reflects the €7,000 VAT history premium. This covers years of clean VAT registration, removal of the 4 to 12 week Revenue review delay, and verified intra-EU trading capability from day one.
Does buying a VAT-registered Irish company include an EORI number?
Not automatically. An EORI number is separate from VAT registration and is issued by Revenue via ROS. Ask the seller whether an EORI is attached to the company. If not, your formation agent can apply for one post-purchase, typically within a few working days.
