For many contractors, CIS administration has always been something to think about when subcontractors are paid. Since April 2026, that’s changed. Even if you haven’t made any subcontractor payments in a month, there may still be action you need to take.
A Quiet Month Still Counts
It is easy to assume that if no subcontractors were paid, there is nothing to do. That is no longer a safe habit. If there were no payments, contractors still need to check whether a nil return is required or whether HMRC has already been told about a period of inactivity.
This small regular routine check can prevent unnecessary penalties and reduce stress later.
Good Records Make Life Easier
CIS runs more smoothly when the basics are kept up to date. Each month, contractors should be clear on:
• which subcontractors were paid
• whether each subcontractor has been verified
• what deductions were made
• whether a nil return is needed
• whether payment records match what happened on site
This does not need to be complicated. The aim is simply to avoid last-minute chasing, missing information, and payment queries that drag on.
Subcontractors Need Clarity Too
Subcontractors are also facing more digital record-keeping, especially as Making Tax Digital for Income Tax expands. Clear payslips, accurate deductions, and easy access to payment information make a real difference. They help subcontractors understand what they have earned, what has been deducted, and what they may need for their own records.
Good subcontractor administration isn’t just about compliance – it builds trust, reduces queries and keeps projects running smoothly.
Make It Routine
The best way to manage CIS is to make it part of the consistent process of the business. A simple routine might include:
• checking who has been paid
• confirming deductions
• reviewing whether a nil return is needed
• keeping records in one place
• dealing with queries quickly
Small checks done regularly are much easier than trying to fix gaps later.
Closing Takeaway
CIS compliance in 2026 is about staying on top of the basics every month. Whether you manage CIS in-house or work with a specialist partner like S+, having a consistent monthly process is the best way to stay organised and reduce compliance risk.
For contractors, that means knowing whether a return, nil return, or inactivity notice is needed. For subcontractors, it means keeping clear records of earnings and deductions.
The businesses that build good monthly habits will find CIS easier to manage and far less time-consuming.
