You finish a 12 hour day on site, eat something hot, and only then remember the shoebox of receipts in the van. Sound familiar? Running a trade business in Ireland is tough on the tools, and the paperwork waits up like a bad in-law. The good news: accounting for a tradesman is not as complicated as it feels, once you understand the three things Revenue cares about, RCT, VAT and clean records.
This guide is for the working tradesperson, the plumber on a boiler swap, the carpenter on a one-off house, the electrician on a commercial fit-out. It covers how RCT and VAT work on Irish sites, what you can claim, and how to decide between sole trader and limited company structure.
What does accounting for tradesmen in Ireland actually involve?
Accounting for a tradesman covers the same building blocks as any small business: bookkeeping, invoicing, expenses, VAT, income tax or corporation tax, payroll if you have staff, and the year-end accounts. The wrinkle, and it is a big one, is the construction sector overlay. If you work in construction, forestry or meat processing, you sit inside Revenue’s Relevant Contracts Tax regime, and that changes how money moves between principals and subcontractors.
For most trades, the day-to-day picture is straightforward: jobs going out as quotes and invoices, materials and tools going in as purchases, a van running up fuel and repairs, and a mix of cash and bank transfers across your account. A good bookkeeping service turns that into a clean ledger that supports your VAT returns and your decisions on pricing. To stay compliant with Revenue, three things matter: keep proper records for six years, file returns on time, and pay what you owe by the deadline. Miss any of these and the surcharges start to bite.
Why is bookkeeping so hard for a working tradesperson?
Time is the obvious culprit. You are quoting at breakfast, on site by eight, chasing a supplier at five. Admin slides to Sunday night, then to “next weekend”, then it does not happen at all. Receipts get damp in the van, suppliers go paperless and the email gets buried, and a cash job for a neighbour gets forgotten because nobody handed you anything to file.
Job-based costs make it worse. A bathroom refit might pull from three suppliers, two of them on account, plus a hired skip and a day rate for a labourer. Pinning the right costs to the right job by memory, six weeks later, is a fool’s errand. The fix is a five-minute-a-day system, which is exactly what the right accountant for tradesmen will help you set up. There is also the irregular income problem: two big jobs land in March and the bank looks healthy, so the van gets replaced; April brings nothing and the VAT bill is due. Without knowing your break-even point and a proper view of cash flow, profit feels like luck.
How does RCT work for tradesmen on Irish construction sites?
Relevant Contracts Tax, or RCT, applies when one operator in the construction industry pays another for relevant operations on a site. The party paying is the principal contractor, the party doing the work is the subcontractor. Before any payment can be made, the principal must register the contract on Revenue’s eRCT system, then notify each payment in advance. Revenue then issues a deduction authorisation telling the principal what rate to apply. A similar withholding mechanism operates under Professional Services Withholding Tax, where state bodies deduct tax at source from payments made to professionals for their services.
The rates are not negotiable. They depend on your compliance history with Revenue.

Who it applies to |
What it means in practice |
|
0% |
Subcontractors with a strong record of tax compliance and on-time filings |
The principal pays you the full amount on the invoice, no deduction |
|
20% |
The standard rate for established subcontractors with a reasonable record |

|
35% |
Subcontractors who are not tax registered, or who have a poor compliance record |
The principal deducts 35%, a real cash flow hit that no one wants for long |
Two things tradesmen miss here, again and again. First, RCT is withholding, not extra tax. The amount deducted is credited to your Revenue account and offsets your income tax or corporation tax bill at year end. Second, your status as a principal matters. If you take on a subcontractor for a single job, you might become a principal yourself for that contract, and the obligation to notify Revenue lands on you. To stay compliant, every contract and every payment must be notified before the money moves. Full detail and the eRCT system itself sit on Revenue’s RCT pages, accessed through Revenue Online Services, and that is the source of truth, not WhatsApp groups.
How does VAT work for tradesmen, and what is reverse charge?
Two VAT rules dominate the trades. The first is the sole trader VAT threshold for services, which has sat around €42,500 in turnover over twelve months at the time of writing. Once you cross it, or expect to, you must register. Many tradesmen register voluntarily below the threshold so they can reclaim VAT on tools, van costs and materials. The current Irish thresholds and rules are summarised on Citizens Information .
The second rule is the reverse charge for construction services between two VAT registered parties. In plain English, when a VAT registered subcontractor invoices a VAT registered principal for construction services subject to RCT, the subcontractor does not charge VAT on the invoice. The principal accounts for the VAT on their own VAT return instead. This confuses every plumber and carpenter on their first commercial subcontract.
- Materials supplied with labour usually follow the labour rate, currently 13.5% for most building work, but pure supply of goods stays at 23%, so mixed jobs need careful invoicing.
- The two-thirds rule still applies; where the value of goods exceeds two-thirds of the total charge, the higher 23% rate may apply to the whole supply.
- Domestic customers cannot reverse charge, so when you fit a bathroom for a homeowner you charge VAT at the appropriate rate on the invoice in the normal way.
- Every sales invoice and purchase receipt needs to be retained, in date order, for six years.
Get this wrong and you can end up paying VAT twice, or charging a principal VAT they cannot reclaim. A short conversation with an accountant before your first big commercial job will save you a far longer one with Revenue later. If you are figuring out whether to register at all, our VAT return service page walks through the mechanics.
Should a tradesman trade as a sole trader or a limited company?
This question gets asked on every kitchen table in Ireland. There is no universal answer, but there are clear factors. A sole trader is simpler and cheaper to run, files an income tax return under self-assessment each year, and pays income tax, PRSI and USC on profits. A limited company is a separate legal entity, pays corporation tax at 12.5% on trading profits, and shields personal assets from most business debts. The companion guide on enterprise.gov.ie covers the wider supports available to small business owners, and our guide to <a href=”LINK”>small business grants in Ireland</a> outlines the funding options worth exploring.

The rough rule of thumb: while you are taking everything you earn straight out as income, sole trader is usually the better deal. Once profits run consistently above what you need to live on, and you can leave money in the business to reinvest, the company structure starts to win on tax. There is more on the trade-off in our post on sole trader vs company, and a walk-through on setting yourself up as a sole trader. If you do go limited, our guide on paying yourself from a limited company explains the salary versus dividends question every working director faces.
What expenses can a tradesman claim in Ireland?
This is where a specialist accountant earns their fee twice over, demonstrating the real value of an accountant for SMEs. Tradesmen routinely under-claim because they are too busy to record, or they over-claim on things Revenue will never accept. Typical allowable expenses for an Irish tradesperson include:
- Hand tools and small power tools, normally fully deductible in the year you buy them.
- Larger plant and equipment, claimed as capital allowances at 12.5% per year over eight years on the cost.
- Van running costs: fuel, motor tax, insurance, repairs, service, AdBlue, lease or hire purchase interest.
- The van itself, claimed via capital allowances at 12.5% over eight years on the qualifying cost.
- Materials and consumables used on jobs.
- Protective clothing, boots, hi-vis, PPE, branded workwear.
- Mobile phone, business broadband or a sensible business share of household broadband.
- Public liability and tools insurance, accountancy fees, trade body membership, training and certs.
- Advertising, website costs, branded signage on the van.
Two areas trip people up. Cars are not vans: if you drive a regular car for trade work, the rules tighten significantly, the deduction depends on CO2 emissions, and only the business proportion is allowable. Vans, by contrast, are typically 100% business use if they are commercial vehicles with no rear seats. Second, food and entertainment are not generally deductible for the proprietor, despite what the lad on the next site told you. Receipt discipline beats clever scheming every time. Photograph every receipt the moment it lands, push it to Xero or whichever accounting software you use, and let the bookkeeping reconcile against the bank weekly. If you’ve already fallen behind on that habit, our <a href=”/catch-up-bookkeeping-ireland”>catch-up bookkeeping Ireland</a> service can get your records back on track fast.
What records does Revenue actually expect a tradesperson to keep?
Revenue’s expectations are plain. You need enough to show that the figures on your return are correct, which in practice means:
- Sales invoices, in sequential number order, with VAT shown where applicable.
- Purchase invoices and receipts for everything claimed.
- Bank statements for every account that touches the business.
- Cash records if you accept cash, with a simple log of jobs paid in notes.
- RCT deduction summaries from each principal you have worked for during the year.
- Mileage records if you claim travel between sites or to suppliers.
- Payroll records for any employee or apprentice, supported by your Revenue payroll submissions.
The rule is six years from the end of the tax year. Digital storage is fine, as long as you can produce a legible copy when asked. Citizens Information has a plain-English summary of the requirement.
How does payroll work when a tradesman takes on a helper?
The minute you have someone on a wage you become an employer, and PAYE Modernisation applies. Every payment to an employee must be reported to Revenue on or before the date it is paid. That means real-time payroll software, registered employments on ROS, and timely payment of PAYE, PRSI and USC each month or quarter depending on size. From 2026 your payroll obligations will expand further as <a href=”/auto-enrolment-ireland/”>payroll pension deductions Ireland</a> come into effect under the new auto-enrolment scheme.
Subcontracting a lad on a couple of jobs is different again, and the line between employee and self-employed contractor matters. Revenue applies a “totality of the relationship” test, and the wider self-employment guidance on gov.ie sets out the criteria. If you decide where they work, when they start, what tools they use, and pay them by the hour, it walks and talks like employment. If they bring their own van, set their own hours, take on their own risk and bill you on an invoice, that is more likely subcontract. A payroll service built for Irish small businesses will keep you the right side of this line.
What about year-end accounts, returns and deadlines?
Sole traders file an income tax return under self-assessment by 31 October each year for the previous calendar year, or mid November if filing and paying through ROS. Preliminary tax for the current year is due on the same day, which catches a lot of first-time filers off guard. Limited companies file a corporation tax return nine months after their accounting year-end, file accounts with the CRO on the annual return date, and run payroll month by month in between. Understanding the filing deadlines businesses Ireland imposes is essential to avoiding penalties and staying compliant.
If you want to know what your numbers actually look like before the deadline panic, monthly or quarterly management accounts are the single biggest improvement most growing trade businesses make. They tell you which jobs make money, which customers pay slowly, and how much to put aside for tax. Add a 13 week cash flow forecast and you stop running out of money the week before the VAT bill. Combine that with credit control on slow payers and you have a finance function that actually serves the business, not the other way round.
Why do tradesmen need a specialist accountant?
A generalist accountant in Ireland can absolutely do your books. The trouble is, they will spend hours on Google figuring out reverse charge, and you will pay for those hours. A specialist accountant for tradesmen has seen 50 RCT contracts, knows the eRCT screens, recognises mixed-rate VAT edge cases, and can spot the cash leak in your job costing from one look at the trial balance. Beyond compliance, the value is in the conversations: how to price a small commercial job differently from a domestic refit, when to swap the old crew cab for a new van, whether to bring on an apprentice. Those answers sit in the lived experience of an accountant who works with tradespeople week in and week out. The same logic applies in other professions — a <a href=”/accountant-for-therapists-ireland/”>therapist accountant in Ireland</a> brings equivalent niche expertise to private practice owners navigating their own sector-specific tax rules.
Frequently asked questions about accounting for tradesmen in Ireland
Do I need an accountant if I am a self-employed plumber or electrician?
Strictly, no. You can file your own income tax return through ROS. In practice, once VAT, RCT or staff enter the picture, the time you save and the tax you do not overpay will cover the fee several times over.
What is the deadline for filing my self-assessment tax return as a sole trader?
The paper deadline is 31 October. If you file and pay through ROS, you usually get an extension into mid November, with the exact date announced by Revenue each year. Preliminary tax for the current year is due on the same day.
Can I reclaim VAT on the van I just bought?
Yes, if you are VAT registered and the van is a qualifying commercial vehicle used for business. You reclaim the VAT in the period of purchase, then claim capital allowances on the net cost over eight years. A car is treated very differently — see our guide on company car vs mileage claims for the full breakdown.
What happens if my RCT rate is 35%?
It means Revenue has flagged a compliance issue, often a missed return or unfiled tax. You can apply to have the rate reviewed, normally back to 20%, once you get current on filings. Letting it sit at 35% is a serious cash drag.
Does the 12.5% corporation tax rate apply to a small construction company?
Yes, the 12.5% rate applies to trading profits of an Irish resident company, small construction companies included. Passive income is taxed at 25%, so the structure of what you take home matters.
How do I switch from sole trader to limited company?
You incorporate a new company through the CRO, register for the relevant taxes on ROS, and then cease the sole trader business by filing a final income tax return covering the period to the cessation date. The trade transfers in on day one, often with the assets moved across at agreed values. The order matters, and so does the timing of contracts, VAT registrations, and other Revenue registration requirements.
