VAT registration is the process of enrolling your business with Revenue to collect and remit Value Added Tax on goods and services sold, required in Ireland once your turnover exceeds €40,000 for services or €80,000 for goods, enabling you to charge VAT and reclaim it on business purchases.

VAT registration is the formal process of enrolling your business with the Revenue Commissioners to collect and account for Value Added Tax (VAT) on the goods and services you sell. Once registered, you receive a VAT number, must charge VAT on your sales, and can reclaim VAT on eligible business purchases. It's a fundamental part of running a compliant business in Ireland.
In Ireland, VAT registration becomes mandatory when your business turnover exceeds specific thresholds: €40,000 for services or €80,000 for goods. These thresholds are based on your annual turnover, and once you exceed them (or expect to exceed them), you must register within 30 days. Failing to register when required can result in penalties and backdated VAT assessments.
Understanding VAT registration is crucial for founders because it affects your pricing strategy, cash flow management, and administrative obligations. Once registered, you'll need to file VAT returns regularly, maintain proper records, and ensure your financial statements accurately reflect your VAT position.
VAT registration becomes mandatory when your business turnover in any continuous 12-month period exceeds the relevant threshold. For businesses primarily supplying services, this threshold is €40,000. For businesses mainly supplying goods, it's €80,000. If you supply both, separate thresholds apply to each category.
You must also register if you expect to exceed these thresholds in the next 12 months. This forward-looking requirement means you can't wait until you've actually breached the threshold—you need to anticipate growth and register in advance. Revenue takes a dim view of businesses that delay registration.
Certain activities trigger immediate VAT registration regardless of turnover, including receiving services from abroad that would be taxable in Ireland, making distance sales to Irish customers above certain limits, or operating in specific sectors with special VAT rules.
The primary benefit of VAT registration is the ability to reclaim VAT on business purchases. If you're buying equipment, software, professional services, or other business expenses, the VAT you pay can be recovered through your VAT returns. For capital-intensive startups, this can represent significant savings.
VAT registration also enhances your business credibility, particularly when dealing with other VAT-registered businesses. B2B customers often prefer working with VAT-registered suppliers, and having a VAT number signals that your business has reached a certain scale and operates professionally.
Being VAT registered enables you to trade seamlessly within the EU using the reverse charge mechanism, simplifying cross-border transactions. This is particularly valuable for Irish tech companies selling SaaS or digital services to customers across Europe.
VAT registration in Ireland is handled through Revenue's Online Service (ROS). You'll need to complete the TR1 form for sole traders or TR2 form for companies, providing details about your business activities, expected turnover, and banking information. The process typically takes 2-4 weeks, though it can be faster.
Before registering, ensure you have your company registration number if you're operating as a limited company, your tax registration details, and information about your business activities and expected supplies. Having accurate projections of your turnover helps Revenue process your application smoothly.
Once approved, you'll receive a VAT number in the format IE followed by 7 digits and 1 or 2 letters. This number must appear on all your invoices, and you'll be assigned a VAT return filing frequency based on your expected turnover—typically bi-monthly, quarterly, or annually for smaller businesses.
The current VAT registration thresholds in Ireland are €40,000 for businesses supplying services and €80,000 for businesses supplying goods. These thresholds have remained stable in recent years, though they're periodically reviewed and may change.
It's important to understand that these thresholds apply to taxable turnover, not total revenue. Certain supplies are exempt from VAT (such as financial services and education), and these don't count towards your threshold calculation. However, zero-rated supplies (like exports) do count towards the threshold even though VAT isn't charged.
For micro companies and startups, monitoring your approach to these thresholds is essential. Growing quickly past the threshold without registering can trigger backdated assessments, penalties, and interest charges that can significantly impact your cash flow.
Yes, you can register for VAT voluntarily even if your turnover is below the mandatory thresholds. Voluntary VAT registration can be advantageous if your business has significant VAT-bearing costs, if you're making supplies to other VAT-registered businesses, or if you're planning substantial capital expenditure.
Voluntary registration allows you to reclaim VAT on startup costs and ongoing expenses from day one. For a tech startup investing in equipment, software licenses, and professional services, the VAT recovery can provide meaningful cash flow benefits in the early stages when every euro counts.
However, voluntary registration also means you must charge VAT on your sales, which could make you less competitive if you're selling to consumers or non-VAT-registered businesses who can't reclaim the VAT. Consider your customer base carefully before opting for voluntary registration.
Once registered, you must charge VAT at the appropriate rate on all taxable supplies and issue VAT invoices to your customers. Irish VAT rates include 23% (standard rate), 13.5% (reduced rate for certain goods and services), 9% (hospitality rate), and 0% (zero rate for exports and certain goods).
You must file VAT returns by your designated due dates—usually the 19th of the month following the end of your VAT period. These returns report your output VAT (charged to customers) and input VAT (paid on purchases), with the difference either paid to Revenue or refunded to you.
Maintaining accurate records is essential. You must keep all invoices, receipts, and documentation supporting your VAT returns for at least six years. Modern accounting software can automate much of this, but the responsibility for accuracy remains with you as the business owner.
Failing to register for VAT when required is a serious compliance issue. Revenue can conduct audits going back several years and assess you for VAT that should have been charged on all sales above the threshold, plus interest and penalties.
The penalties for late registration can be substantial. You'll owe the VAT that should have been collected (even if you didn't charge it to customers), interest on late payments at approximately 8% per annum, and potential fixed penalties for non-compliance.
Beyond the financial impact, VAT compliance issues can affect your business relationships and credibility. Investors conducting due diligence, potential acquirers, or even business customers may view tax compliance failures negatively. For founders considering seed investment or Series A funding, clean tax compliance is essential.
VAT registration requires careful consideration of your pricing strategy. If you're selling to consumers or non-VAT-registered businesses, adding 23% VAT to your prices makes your products or services more expensive compared to non-VAT-registered competitors.
Many businesses choose to absorb the VAT impact by reducing their pre-VAT prices to keep the final price unchanged. This approach maintains competitiveness but reduces your margin. The right strategy depends on your market position, competitor pricing, and customer price sensitivity.
For B2B sales, VAT registration is typically neutral because your customers can reclaim the VAT you charge. In fact, being VAT registered is often expected in B2B contexts and can help you win larger contracts with established companies that require VAT invoices.
