Sole Trader or Limited Company for a Self-Build in Ireland — The Tax and VAT Trade-Off
On this page
Sole trader registration lets most self-builders reclaim VAT at 13.5% on labour and 23% on materials.
Most Irish self-builders register as a sole trader with Revenue before they start spending on materials. The reason is VAT: registered sole traders can reclaim VAT on materials (23%) and a portion of VAT on labour (13.5%) under the Revenue VAT 13B scheme for residential property. Without registration, VAT is a real cost — typically €30k–€90k on a €500k build. The registration itself is free and takes about 10 working days. Limited company is overkill unless you're building more than one house in a 24-month period; the administrative burden (annual returns, Corporation Tax, payroll if you employ anyone) outweighs the benefit for a single self-build. Talk to your accountant before you register — the right structure depends on your tax band, your income, and whether you intend to claim the VAT refund.
When this matters most
You're at the pre-construction phase and need to decide on a legal entity for the build.
When this doesn't apply
You've already registered, or you're using a main contractor who is the VAT-registered entity.
