CIS (Construction Industry Scheme) Services for Construction Businesses
Stay compliant, avoid penalties, and manage subcontractors with confidence. Expert CIS support for construction contractors and subcontractors.
Understanding CIS – and Getting It Right
The Construction Industry Scheme (CIS) can be a minefield if you’re not on top of it. Whether you’re a contractor who hires subcontractors or a subcontractor working under deduction, there are strict rules set by HMRC — and getting it wrong can lead to serious penalties.
At RCL Accountants, we help construction businesses navigate CIS with ease. From registration to monthly returns and verification, we manage the process so you can get on with running your sites and growing your business.
Our CIS Services
Whether you're a contractor or subcontractor, we’ve got your obligations covered:
For Contractors:
CIS Registration & Setup
We get you registered with HMRC as a contractor under the scheme and set up for digital filing.
Subcontractor Verification
We handle the process of verifying your subcontractors with HMRC to ensure you apply the correct deduction rate (20%, 30%, or 0%).
Monthly CIS Returns
We prepare and submit your CIS returns to HMRC on time, every month – so you avoid late penalties and stay compliant.
Payment & Deduction Statements
We provide the correct statements to your subcontractors so they have the records they need for their own tax returns.
Compliance Reviews & Support
We’ll review your processes, ensure you’re applying deductions correctly, and prepare you for any HMRC review.
For Subcontractors:
Gross status
We’ll assess your eligibility to apply for gross status and if applicable we will attend to this on your behalf.
CIS Registration
We’ll get you properly registered so you’re taxed at 20% instead of the higher 30% rate.
Tax Deduction Statements
We help you keep track of all deductions made by contractors so you’re ready for your year-end tax return.
Self Assessment Tax Returns
We’ll make sure all CIS deductions are accurately reported and help you claim back any overpaid tax – many subcontractors are due refunds!
Expense Tracking & Advice
We’ll advise on what you can claim to reduce your tax bill and maximise your refund.
Why CIS Compliance Matters
CIS isn’t optional — it’s a legal requirement for most construction businesses in the UK. HMRC penalties for non-compliance can include:
Fines for late returns
Penalties for incorrect deductions
Interest on underpaid tax
Investigations into your business
We help you stay fully compliant all year round and remove the stress of dealing with HMRC.
