The Construction Industry Scheme (CIS) is a vital part of doing business in the UK construction sector. Whether you’re a contractor or a subcontractor, CIS registration is not just a formality—it’s a necessity. At BNA Consulting, we specialise in helping businesses like yours navigate the complexities of CIS with ease, saving time, reducing risk, and ensuring HMRC compliance from the outset.
What is CIS Registration and Why Does It Matter?
CIS was introduced by HMRC to improve tax compliance in the construction industry. Under this scheme, contractors deduct money from subcontractors’ payments and pass it directly to HMRC. These deductions count as advance payments towards the subcontractor’s tax and National Insurance.
However, without proper CIS registration, subcontractors could face higher tax deductions—up to 30% instead of the standard 20%. Worse still, contractors who fail to register or comply can face penalties, audits, and even reputational damage.
Put simply: if you’re working in construction, CIS registration is not optional—it’s critical.
Who Needs to Register for CIS?
-
Contractors: Businesses or individuals that pay subcontractors for construction work.
-
Subcontractors: Those who carry out construction work for a contractor.
You could be a limited company, partnership, or sole trader—if construction is part of your business, you should be registered.
The Common Pitfalls of Going It Alone
Trying to register yourself might seem straightforward, but many business owners encounter unexpected complications, such as:
-
Submitting incorrect information to HMRC
-
Delays in registration approval
-
Misclassifying workers as employees or subcontractors
-
Errors in calculating deductions
-
Failing to submit monthly CIS returns on time
Mistakes like these can lead to severe penalties and a lot of unnecessary stress. That’s where we come in.
