VAT Registration Threshold Ireland - What Sole Traders Need to Know

The VAT threshold is the most practical number a sole trader tradesman needs to know. Cross it without registering, and you face penalties and backdated VAT bills. Understand it, and you can make an informed decision about whether and when to register.

This guide gives you the exact figures, explains what counts toward the threshold, and covers the case for voluntary registration below the limit.

What is the VAT threshold in Ireland for sole traders?

There are two main thresholds in Ireland, depending on whether you supply services or goods. Both have applied since 1 January 2025:

Most sole trader tradesmen - plumbers, electricians, builders, roofers - are primarily providing services, even when materials are included in the job. The €42,500 threshold is the relevant one.

What counts toward the VAT threshold?

The threshold is based on your taxable turnover - the total amount you charge customers (excluding any VAT you might already be charging), not your profit or your net income after expenses.

What counts:

• All labour income from jobs
• Materials charged to customers as part of a job
• Any other taxable supplies you make in Ireland

What does not count:

• Exempt supplies (very few for tradesmen)
• Income from outside Ireland

Revenue measures your turnover over a calendar year, January to December. You must register once your turnover in the current calendar year goes over the threshold, or if it went over in the previous calendar year.

What happens when you cross the threshold?

Once your turnover goes over €42,500 in a calendar year, you must register for VAT with Revenue - do it as soon as you go over. Revenue will then assign you a VAT registration number and a filing frequency (typically bi-monthly for most sole traders).

If you do not register when you should, Revenue can charge you the VAT you should have charged from the date you went over, plus interest and penalties - even though you never collected that VAT from your customers.

Should you register voluntarily below the threshold?

You can elect to register for VAT even if your turnover is below €42,500. Voluntary registration makes sense in several situations:

When voluntary registration is worth it

• You buy significant materials. Once registered, you can reclaim the VAT you paid on materials, tools, and most business expenses. If you are buying materials regularly, this reclaim can outweigh the administration overhead.
• Your customers are VAT-registered businesses. If your clients are VAT-registered themselves (other contractors, commercial customers), they can reclaim the VAT you charge them. Being VAT-registered is not a price disadvantage - it is neutral or positive.
• You are close to the threshold anyway. If you are within a few thousand euro of €42,500, registration now avoids the urgency of having to register quickly when you cross the line mid-year.

When to stay below the threshold

• Your customers are private homeowners. Homeowners cannot reclaim VAT, so registering means your quotes are immediately 13.5% more expensive to your customers. If your competitor is not registered, you are at a price disadvantage for like-for-like jobs.
• Your margins are tight and material costs are low. If you are a labour-only tradesman with very low material costs, the VAT reclaim benefit is minimal and the administration burden may not be worth it.

How do you register for VAT in Ireland?

You register through Revenue's online services:

1. Log in to Revenue's myAccount (for individuals) or ROS (Revenue Online Service) if you already use it
2. Complete the Form TR1 (sole trader VAT and income tax registration) online
3. Provide your PPS number, business name, business address, and estimated turnover
4. Specify the date from which you want registration to take effect

Revenue will then issue your VAT registration number. Once registered, you must charge VAT on all eligible invoices from the effective date. If you are registering voluntarily, you cannot backdate the registration to an earlier VAT period.

What to do once you are registered

From the date your registration takes effect:

• Add your VAT number to all invoices
• Charge the correct VAT rate for each job - 13.5% for most work on buildings, labour and materials together, unless the materials cost more than two-thirds of the price, when the whole job is 23%
• Leave the VAT off work you do as a subcontractor for a principal contractor under RCT - the principal accounts for it (the reverse charge)
• Keep records of all VAT you charge and all VAT you pay on business expenses
• File bi-monthly VAT returns through ROS and pay any VAT due
