If your construction business has Gross Payment Status, you know how important it is. It means you get paid in full, without any tax taken off first. But starting in 2026, keeping that status is going to get much harder.
The government is introducing tough new rules to stop fraud in the Construction Industry Scheme (CIS). The upcoming Finance Bill 2025-26 includes strict measures that target how you manage the people you hire. If you rely on messy spreadsheets to track your supply chain, your business is at serious risk of losing its most valuable tax benefit.
The New Legal Standard: No More Excuses
In the past, if a subcontractor you hired committed tax fraud, you might not be blamed if you simply did not know about it. That is changing.
HMRC is bringing in a strict “knew or should have known” test. This means ignorance is no longer a valid excuse. If one of your subcontractors avoids paying their taxes, HMRC will look at your records. They will ask if you did enough checking (subcontractor due diligence) before you hired them. If HMRC decides you should have known that the subcontractor was breaking the rules, you will be held responsible.
As Sharon Brown, a Financial Controller in the industry, points out, messy records make it impossible to know what is really going on:
"There was a disconnect between our understanding of project costs and that of the project managers. They assumed that if the work was done, it had been invoiced and paid for, whereas we had no way of knowing if we were missing costs."

Under the new rules, this kind of confusion is a massive legal risk.
The Stakes: Losing Your Gross Payment Status
The penalties for failing this new test are brutal, especially for directors. If HMRC believes you failed to check your supply chain properly, the punishments are fast and severe:
- Immediate Loss of Status: You will lose your Gross Payment Status in 2026 instantly. This will ruin your cash flow because 20% or 30% of your income will be held back on every job.
- A 5-Year Ban: You will not be allowed to reapply for Gross Payment Status for five full years.
- Personal Fines: Directors can face personal penalty charges of up to 30% of the lost tax.
The government is very serious about this crackdown. You can read the full details in HMRC’s policy paper on tackling CIS fraud.
Fixing the Problem is Fast and Easy
Getting your systems ready for these strict new rules does not mean you have to pause your business. Many builders worry that upgrading their software will take months of training. But you do not need a giant, expensive IT project.
Because Planyard is built specifically to sit right on top of your current accounting tools, it works the way you already work. You can get your very first project set up, running, and completely protected in just 1 to 2 hours.
Less Admin Work, More Safety
The best part is that protecting your Gross Payment Status actually saves you time. Instead of spending days chasing down old emails and broken spreadsheets to prove you did the right checks, everything happens automatically as you manage the job.
As Lee Covington, Owner of the E&N Group, found out after dropping his manual spreadsheets:
"It’s at least a full-time job’s worth of work saved. And it means when I look at the numbers, I know they’re right – nothing’s gone missing."

You get total peace of mind against HMRC audits without the heavy admin work.
Building an Audit Trail with Planyard
If you are a growing main contractor making £1 million to £30 million a year, you cannot protect yourself using emails and disconnected Excel files. You need a clear, unchangeable digital paper trail to prove to HMRC that you check every subcontractor.
This is exactly what Planyard does. Planyard is a simple project system that links directly to your accounting software, like Xero or QuickBooks. It forces your team to follow a strict, clean process for every single job.
- Digital Proof: Planyard creates a timestamped record every time you onboard a subcontractor, approve a purchase order, or pay an invoice.
- Better Accountability: As QS Daniel De Rocco explains, “The introduction of structured purchase order workflows has significantly strengthened financial accountability across the organisation.”
- Automatic Checks: By keeping all your subcontractor data, compliance documents, and CIS statements in one secure place, you always have the proof you need if HMRC comes knocking.
Do not wait until the HMRC CIS fraud rules change to fix your systems. Upgrading your tools today is the only way to defend your Gross Payment Status and keep your cash flow safe.
