How RCT Works Today And Why The Old Forms No Longer Apply
This blog clears that up. It explains how RCT used to work, why the old forms were phased out, and most importantly, how RCT actually works today. If you have ever wondered whether forms like RCT1, RCT46, or C2 cards still matter, this is where the confusion finally ends.
Relevant Contracts Tax has been part of Irish business life for a long time, especially in construction and other labour heavy sectors. Because of that long history, many people still come across old guides, scanned PDFs, or advice that talks about paper forms, cards, and certificates. At first glance, it all looks official. In reality, much of it belongs to a system that no longer exists.
This blog clears that up. It explains how RCT used to work, why the old forms were phased out, and most importantly, how RCT actually works today. If you have ever wondered whether forms like RCT1, RCT46, or C2 cards still matter, this is where the confusion finally ends.
The Old RCT System And Why It Existed
Before electronic reporting became standard, RCT relied heavily on paperwork. Principal contractors and subcontractors filled out physical forms, applied for cards, and kept folders of carbon copy certificates. At the time, this made sense. Revenue needed a way to track payments in industries where subcontracting was widespread and cash flow moved quickly.
Forms like RCT1 were used to register contracts. C2 cards acted as proof that a subcontractor was tax compliant. Relevant payments cards allowed subcontractors to be paid without tax being deducted at source. Monthly and annual returns summarised everything for Revenue.
It was a system built for its era. Slower, manual, and heavily dependent on people doing the right thing with paperwork.
Why The Paper Based RCT System Was Replaced
Over time, the weaknesses became obvious. Paper forms were lost. Cards expired. Payments were made before forms were processed. Revenue often found out about issues months or years later.
From a business point of view, it was frustrating. From a tax compliance point of view, it was risky.
The move to electronic RCT was not cosmetic. It was a structural change designed to bring real time visibility into payments, improve accuracy, and reduce disputes. Revenue introduced the electronic RCT system, often called eRCT, to remove guesswork and delay from the process.
Once eRCT came in, the old forms stopped being relevant almost overnight.
Common Old RCT Forms People Still Ask About
Even today, people regularly ask about forms that no longer apply. It is worth addressing them clearly.
RCT1 was once used to notify Revenue when a contract started. Today, contracts are managed electronically through ROS without a standalone form.
C2 cards used to confirm a subcontractor’s tax compliance. These cards no longer exist. Compliance is checked automatically by Revenue systems.
RCT46 and RCT47 related to relevant payments cards. Again, these have been replaced entirely by electronic rate determination.
RCTDC certificates were issued to subcontractors when tax was deducted. Today, deductions are recorded digitally and visible on the subcontractor’s Revenue record.
RCT30 and RCT35 returns summarised monthly and annual activity. These are no longer required in the same way because reporting now happens at payment level.
If a guide focuses heavily on these forms, it is outdated.
How RCT Works Today In Practice
Modern RCT is handled fully through Revenue Online Service. There are no physical cards, certificates, or paper returns.
When a principal contractor is about to pay a subcontractor, they submit a payment notification through ROS. This must happen before the payment is made. The notification includes the subcontractor details and the gross amount due.
Revenue responds instantly with a deduction rate. This rate reflects the subcontractor’s current compliance position.
The principal contractor then pays the subcontractor the net amount. Any tax deducted is automatically allocated to the subcontractor’s tax record.
Everything is logged digitally. Both parties can see what was reported and when.
Why Timing Matters More Than Ever
One thing has not changed. Timing is critical.
Under the modern system, submitting the notification after payment is still considered late. The system may be electronic, but the rule remains the same. Notify first, pay second.
This is where many businesses slip up. They assume electronic reporting allows flexibility. It does not. In fact, the system is stricter because Revenue can see payment patterns instantly.
Building the RCT step into payment workflows is essential.
What Happened To Certification And Compliance Checks
Under the old system, compliance was proven with cards. Under the new system, compliance is assessed automatically.
Revenue reviews tax filings, payments, and overall behaviour. Based on that, a deduction rate is assigned. Zero percent rates still exist, but they are granted electronically rather than through certificates.
This change removed discretion from the process. No one can wave a card or argue compliance at the point of payment. The system decides.
For compliant subcontractors, this works well. For non compliant ones, it can be uncomfortable, but it is transparent.
Record Keeping In The Modern RCT System
Paper records are no longer required, but record keeping is still vital.
Principal contractors should retain copies of payment notifications, Revenue responses, invoices, and proof of payment. Subcontractors should regularly review their RCT records in ROS to ensure payments are reported correctly.
The difference is that everything now lives digitally. Audits focus less on missing forms and more on inconsistencies between payments, dates, and amounts.
Accuracy matters more than ever.
Why Old RCT Guides Still Circulate
Many older contractors learned RCT under the old system and still reference what they know. Some online guides were never updated and continue to rank in search results. PDFs get shared without context.
This creates confusion, especially for new businesses trying to do the right thing.
The key thing to remember is that Revenue guidance has moved on. If advice involves physical forms, cards, or certificates, it belongs to a different era.
Risks Of Following Outdated RCT Advice
Following outdated advice is not harmless. It can lead to real problems.
A contractor might delay notification thinking a form needs to be processed. A subcontractor might assume certification protects them when it no longer exists. Payments may be made incorrectly, triggering liability.
Revenue does not accept outdated systems as a defence. Businesses are expected to follow current rules, regardless of what an old document says.
Understanding what no longer applies is just as important as knowing what does.
How Businesses Should Approach RCT Now
The best approach to RCT today is procedural.
RCT should be part of payment approval. No notification, no payment. That mindset prevents most issues.
Using accounting software that integrates with ROS reduces errors. Many businesses also choose to outsource RCT administration, especially where volumes are high.
Training matters too. Anyone involved in approving payments should understand that RCT is not optional and not retrospective.
When systems are clear, RCT becomes routine rather than stressful.
RCT For New Contractors And Subcontractors
For new entrants, the modern RCT system is actually simpler than the old one. There are fewer moving parts, fewer documents, and less ambiguity.
The challenge is unlearning outdated advice. New contractors should rely on current Revenue guidance or professional support rather than inherited knowledge from older systems.
Once the basics are understood, RCT fits neatly into normal business processes.
Why Revenue Prefers The Electronic System
From Revenue’s point of view, eRCT offers visibility, consistency, and fairness.
Payments are reported in real time. Compliance is assessed automatically. Errors are flagged early rather than years later.
This benefits compliant businesses too. Less uncertainty, fewer disputes, and clearer records make life easier for everyone involved.
The old system depended on trust and paperwork. The new system depends on data.
Final Thoughts
RCT has not disappeared, but the way it operates has changed completely.
Paper forms, cards, and certificates are part of RCT history, not current practice. Understanding that difference prevents mistakes and frustration.
Modern RCT is faster, stricter, and more transparent. When handled correctly, it is predictable and manageable. When handled using outdated guidance, it quickly becomes a problem.
For any business operating under RCT today, the rule is simple. Ignore the old forms. Follow the electronic process. Build it into your workflow. Do that, and RCT becomes just another routine step in getting paid or paying others.
FAQs About Old RCT Forms And The Modern RCT System
Are RCT Forms Like RCT1 And RCT46 Still Used Today?
No. These forms belong to the old paper based RCT system and are no longer used. All RCT reporting is now handled electronically through Revenue Online Service.
Do C2 Cards Still Exist For Subcontractors?
No. C2 cards were abolished when electronic RCT was introduced. Subcontractor compliance is now checked automatically by Revenue systems.
