We here at JP Egan & Company know that Relevant Contracts Tax is one of the most important, and most demanding, compliance areas for construction businesses in Ireland. Whether you are a main contractor engaging subcontractors or a subcontractor working for others, RCT affects how payments are made, how much tax is deducted and how cash flows through your business. Mistakes can lead to substantial penalties, so understanding the key rules is essential.
RCT is a withholding tax system that applies to payments made by principal contractors to subcontractors in the construction, forestry and meat processing sectors. Since Revenue moved the system fully online, nearly every step must be completed electronically and in the correct order. Here are five compliance points every Irish construction business should have firmly in place.
1. Know When RCT Applies
RCT applies where a principal contractor pays a subcontractor under a relevant contract for relevant operations. In construction, relevant operations cover a broad range of work, including building, alteration, repair, extension, demolition, installation of heating, lighting and other systems, and related work such as painting and decorating.
Principal contractors are not limited to traditional building firms. Property developers and certain other businesses connected to construction activity can also be treated as principals and required to operate RCT. If your business regularly engages contractors for construction work, it is worth confirming whether you have RCT obligations, as ignorance of the rules is not accepted as an excuse.
2. Notify Contracts and Payments Before You Pay
The online RCT system places clear obligations on principal contractors. Before making the first payment under a new contract, you must notify Revenue of the contract. Then, before each individual payment is made, you must notify Revenue of the payment. Revenue responds with a deduction authorisation setting out how much tax, if any, must be deducted.
The rate depends on the subcontractor's tax record. Subcontractors with a strong compliance history are generally given a 0% rate, those registered with Revenue but not meeting the criteria for 0% are typically subject to 20%, and those unknown to Revenue or with serious compliance issues face 35%. Making a payment without first notifying Revenue, or deducting the wrong amount, can lead to penalties linked to the rate that should have applied, so the notification must always come before the payment.
3. Get Employment Status Right
One of the most significant risks in the construction sector is treating workers as subcontractors when they are, in reality, employees. RCT applies only to genuine subcontractors. If a worker is in fact an employee, PAYE, USC and PRSI should be operated through payroll, and the business may also have employment law obligations.
Revenue and the Department of Social Protection look closely at employment status in construction. Factors such as who controls how and when the work is done, whether the worker provides their own equipment, whether they can send a substitute and whether they bear financial risk all play a part. Revenue updated its guidance following a significant Supreme Court decision on employment status, introducing a more structured approach to the assessment. Getting it wrong can result in back taxes, interest and penalties, so status should be reviewed carefully for every engagement.
4. File Returns, Pay on Time and Apply the VAT Reverse Charge
Principal contractors must file RCT returns and pay over any tax deducted by the relevant deadline. Revenue's system prepares the return based on the payment notifications made during the period, but it remains your responsibility to check it, amend it if necessary and pay the tax due on time.
VAT works differently in construction too. Where RCT applies, the principal contractor generally accounts for the VAT on services received from subcontractors under the reverse charge system, rather than the subcontractor charging VAT on their invoice. Applying the reverse charge correctly is essential, as errors can result in VAT being overpaid, underpaid or claimed incorrectly.
5. Subcontractors: Protect Your Rate and Your Cash Flow
For subcontractors, RCT has a direct impact on cash flow. Having 20% or 35% deducted from every payment can create serious pressure, especially for smaller businesses with tight margins. Keeping your tax affairs fully up to date, filing returns on time and paying liabilities promptly are the best ways to secure and maintain a 0% rate.
Where tax has been deducted, it can be credited against your tax liabilities, and any excess may be refunded once the relevant returns have been filed and your affairs are in order. Keep track of every deduction made and check that the amounts shown by Revenue match your records, so you can claim the full credit due.
Keep Clear Records
For both principals and subcontractors, good records are vital. Keep copies of contracts, contract and payment notifications, deduction authorisations, invoices and payment records. These provide the evidence needed if Revenue reviews your RCT compliance and make it easier to resolve any discrepancies quickly.
Stay Compliant and Protect Your Business
RCT is strict, and the penalties for getting it wrong can be severe. However, with clear processes for checking contracts, notifying payments, assessing employment status, filing returns and keeping records, construction businesses can manage RCT efficiently and avoid costly errors.
At JP Egan & Company, we help construction businesses and subcontractors manage their RCT obligations, review employment status and stay fully compliant with Revenue.
