Reverse Charge VAT (construction)

aka Construction VAT Reverse Charge, RCV

A VAT rule specific to Irish construction services: where both parties are RCT-registered, the subcontractor invoices net of VAT and the principal accounts for the VAT in their own VAT3 return.

Definition

The VAT Reverse Charge for construction services is an Irish-specific rule that shifts responsibility for accounting for VAT from the supplier to the recipient. It applies where a subcontractor supplies construction services to a principal contractor and both parties are RCT-registered with Revenue. Under the reverse charge, the subcontractor issues an invoice that does not include VAT but carries the note 'VAT on this supply to be accounted for by the principal contractor'. The principal then self-accounts for the VAT in their own VAT3 return: the output VAT in box T1, and (where deductible) the input VAT in box T2. The net effect for a fully VAT-registered principal is zero cash flow, but the return lines must still be completed correctly. The reverse charge does not apply to materials supplied separately, to hauliers, or to supplies to non-RCT recipients such as homeowners. Haulage, plant hire with an operator, and site clearance are all caught; straightforward supply of materials alone is not.

Why it matters for software choice

The construction VAT reverse charge is the single most misapplied VAT rule in Irish SME accounting. Errors in either direction (subcontractors charging VAT they should not, or principals forgetting to self-account) can sit undetected for years and become large assessments on Revenue audit. Accounting software that offers a dedicated reverse-charge tax rate on sales and purchase invoices removes most of the manual risk.
