What is the Relevant Contracts Tax (RCT)?
The Relevant Contracts Tax (RCT) is a tax withholding system operated by Revenue Commissioners that applies to the construction industry. It requires contractors to deduct tax from payments made to subcontractors. The amount deducted depends on whether the subcontractor is registered for RCT and their status. This scheme applies to all payments for construction services, including labour and materials.
How RCT Deductions Work
- Determine subcontractor status: Establish whether they are registered RCT, unregistered, or have gross payment status.
- Calculate labour cost: Subtract materials supplied by the contractor from the gross payment.
- Apply deduction rate: Multiply the labour amount by the appropriate RCT rate (20%, 30%, or 0%).
- Make net payment: Pay the subcontractor the gross amount minus the RCT deduction.
- Remit to Revenue Commissioners: Send the deducted amount to Revenue Commissioners by the 23rd of the month following deduction (RCT is paid monthly).
RCT Deduction Rates Explained
20% Registered RCT
Applies when the subcontractor has a valid RCT registration with Revenue Commissioners and a valid Unique Taxpayer Reference (UTR). This is the standard rate for registered subcontractors.
30% Unregistered
Applies when the subcontractor is not registered for RCT or does not have valid registration documentation. This is a higher rate to protect Revenue Commissioners revenue.
0% Gross Payment Status
Applies to subcontractors who have been given Gross Payment Status by Revenue Commissioners. These are typically larger, more established companies with excellent compliance records. No deduction is required.
Who Needs to Register for RCT?
Contractors
Contractors must register for RCT if they:
- Engage subcontractors in the construction industry
- Operate any size of business
- Must register before paying subcontractors
Subcontractors
Subcontractor registration is optional but recommended to:
- Reduce deduction from 30% to 20%
- Improve business credibility
- Simplify tax reporting
RCT and VAT Reverse Charge
RCT and VAT Reverse Charge are separate rules that both apply to construction services in Ireland. Here's how they differ:
| Aspect | RCT | VAT Reverse Charge |
|---|---|---|
| Purpose | Tax withholding on labour | VAT liability transfer |
| Applies to | Construction labour | Qualifying construction supplies |
| Who collects | Contractor withholds | Customer pays direct to Revenue Commissioners |
| Can coexist | Yes, both rules can apply simultaneously to the same invoice | |
