RCT for Non-Resident Subcontractors in Ireland: A Practical Guide
If you are an overseas construction business taking on subcontracting work in Ireland, you may have Irish tax obligations even if your business is not resident in Ireland.
One of the main rules to understand is Relevant Contracts Tax (RCT).
RCT is a withholding tax that applies to certain payments made by principal contractors to subcontractors in the construction industry. For non-resident subcontractors, understanding how RCT works can help avoid unexpected deductions and ensure the correct tax treatment is applied.
In this guide, we explain how RCT applies to non-resident subcontractors and some of the wider Irish tax considerations that may arise.
Does RCT Apply to Non-Resident Subcontractors?
Yes. Revenue confirms that RCT applies to non-resident subcontractors where relevant work is being carried out in Ireland. If a principal contractor is paying a non-resident subcontractor for work that falls within RCT, the principal contractor should deduct RCT from the gross payment.
This applies even where the principal contractor is also non-resident.
RCT rates are currently 0%, 20% and 35%, depending on the subcontractor’s tax compliance position.
For a broader explanation of how RCT works, including the different rates and the general RCT process, see our guide to Understanding Relevant Contracts Tax (RCT) in Ireland.
How Does RCT Work for a Non-Resident Subcontractor?
RCT compliance is handled electronically through Revenue’s Online Service (ROS).
The principal contractor is responsible for notifying Revenue about relevant contracts and payments. Before making a payment to a subcontractor, the principal contractor submits a payment notification to Revenue showing the gross payment and payment date.
Revenue then issues a deduction authorisation confirming whether RCT must be deducted and, if so, the amount. Where RCT is deducted, the principal contractor should provide the subcontractor with the relevant deduction authorisation details.
For an overseas business, it is important to keep copies of deduction authorisations and other RCT records, particularly where the business expects to claim a refund or needs to reconcile the deductions against its Irish tax position.
Can a Non-Resident Subcontractor Claim Back RCT?
Potentially, yes. Revenue allows registered non-resident subcontractors to apply for a refund of RCT during the year.
An individual subcontractor uses Form IC1, while a company subcontractor uses Form IC3. An RCT questionnaire is also required for each relevant contract.
The tax authority in the subcontractor’s country of residence must certify the relevant form in the year in which the income was earned. A copy of the deduction authorisation must also be provided with the claim.
This can be particularly important for overseas contractors who have had significant amounts deducted from payments for work carried out in Ireland.
It is also worth noting that Revenue automatically credits RCT deducted to the subcontractor’s tax record. Depending on the circumstances, those credits may be offset against Irish tax liabilities rather than being immediately repaid.
What About VAT?
VAT is another important consideration for non-resident subcontractors.
Where RCT applies to construction services supplied by a subcontractor to a principal contractor, the VAT reverse charge generally applies. Instead of the subcontractor charging and accounting for the VAT, the principal contractor accounts for the VAT directly to Revenue.
Revenue’s current guidance states that non-resident subcontractors providing construction services to principal contractors are not required to register for Irish VAT for those supplies. However, they may choose to register in order to claim credit for VAT paid in Ireland.
The position can differ for certain activities and supplies outside the relevant construction services, so the VAT treatment should be checked based on the actual contract and work being carried out.
Do Non-Resident Subcontractors Have Other Irish Tax Obligations?
RCT is only one part of the picture. Depending on the business structure, activities and circumstances, a non-resident contractor or subcontractor may also have Irish obligations relating to:
- Corporation Tax or Income Tax
- VAT
- PAYE, PRSI and USC where employees are involved
- Irish tax registrations
- Tax returns and other Revenue filings
Revenue specifically advises non-resident contractors to consider their other Irish tax obligations in addition to RCT. The correct obligations depend on the circumstances of the business and the nature of the work being carried out in Ireland.
For this reason, an overseas business should not assume that dealing with RCT automatically means all of its Irish tax obligations have been dealt with.
What If a Non-Resident Subcontractor Receives a 0% RCT Rate?
A non-resident subcontractor may be able to receive a 0% RCT rate where it has an up-to-date compliance record with Revenue.
However, a 0% rate does not mean that the RCT process can simply be ignored.
The principal contractor must still submit a payment notification to Revenue and receive a deduction authorisation. Where Revenue confirms a 0% rate, the principal contractor can make the payment without deducting RCT.
Maintaining an up-to-date tax compliance position can therefore be important for businesses that regularly undertake work in Ireland.
What Records Should Non-Resident Subcontractors Keep?
Overseas subcontractors should keep clear records of their Irish projects and payments.
These may include:
- Contracts with Irish principal contractors
- RCT contract and payment information
- Deduction authorisations
- Invoices and payment records
- RCT deductions
- Irish tax registration details
- VAT records
- Copies of tax returns and Revenue correspondence
Revenue guidance also requires subcontractors to keep records of relevant payments and deduction authorisations.
Good record-keeping can make it easier to reconcile payments, support refund claims and respond to Revenue queries.
Common Mistakes for Non-Resident Subcontractors
Assuming RCT Does Not Apply Because the Business Is Overseas
The fact that a business is based outside Ireland does not automatically remove relevant construction work from the RCT system.
Where the relevant work is carried out in Ireland, RCT can apply to non-resident subcontractors.
The amount deducted from payments can vary depending on the subcontractor’s Revenue compliance position.
Businesses should understand what rate applies and check their Revenue records where appropriate.
RCT and VAT are separate tax rules, although they interact in the construction sector through the VAT reverse charge.
A business should consider both separately when reviewing its Irish tax obligations.
Failing to Keep Deduction Records
Without appropriate documentation, reconciling RCT deductions or making a refund claim can become more difficult.
An overseas contractor may have other Irish tax or payroll obligations depending on its activities and structure.
RCT should therefore be considered as part of the business’s overall Irish tax position rather than in isolation.
What Should You Do Before Starting Construction Work in Ireland?
If your business is based outside Ireland and you are planning to take on construction work here, it is worth establishing your Irish tax position before the project begins.
Consider:
- Whether the work falls within RCT
- Whether you need to register for Irish taxes
- How RCT will be deducted from payments
- Whether the VAT reverse charge applies
- Whether you may be entitled to an RCT refund
- Whether you have employees who create Irish payroll obligations
- What records you need to maintain
Getting these points right at the beginning can help prevent problems later.

Final Thoughts
For non-resident subcontractors, carrying out construction work in Ireland can create Irish tax obligations even when the business is based overseas.
RCT is an important part of that picture, but it should not be considered in isolation. Understanding how RCT deductions, VAT reverse charge, refund claims and other Irish tax obligations fit together can help overseas businesses avoid unexpected problems.
If you are planning to undertake construction work in Ireland, it is worth reviewing your tax position before the project begins rather than dealing with issues after payments have already been made.
