Construction Industry Scheme (CIS)
Specialist advice for contractors and subcontractors under the Construction Industry Scheme
Specialist Support for CIS Contractors and Subcontractors
The Construction Industry Scheme (CIS) sets strict rules on how contractors pay subcontractors and how tax is deducted at source. It’s designed to bring compliance to the sector — but for many businesses, it creates unnecessary admin, cash flow challenges, and risk of penalties if anything is missed.
At Citiline, we simplify CIS. Whether you are a contractor making deductions or a subcontractor trying to reclaim overpaid tax, we take care of registration, reporting, and compliance so you can focus on running your projects.
How We Help Contractors
Contractors have a duty to register with HMRC, verify subcontractors, and deduct tax at the correct rate before paying them. We make sure your systems are watertight by handling:
HMRC registration and verification: Registration and verification of subcontractors with HMRC.
Correct CIS deductions: Application of CIS deductions at 20% or 30% where applicable.
Monthly CIS returns: Filing CIS returns on time to avoid penalties.
Record keeping: Managing statements and compliance records for subcontractors.
Cash flow advice: Helping contractors manage cash flow under CIS rules.
How We Help Subcontractors
Subcontractors often face deductions at source, reducing take-home pay and creating refund claims at year end. We help by:
HMRC registration: Ensuring you are registered correctly to avoid 30% deduction rates.
Gross payment status: Applying for gross payment status where appropriate.
Tax return filing: Preparing returns to reclaim overpaid CIS tax efficiently.
Record keeping support: Helping you maintain accurate records for claims.
Keeping You Compliant and Efficient
HMRC penalties for late CIS returns or incorrect deductions can be severe. Our role is to take the pressure off — ensuring everything is correct, submitted on time, and optimised for your business. By outsourcing CIS compliance to us, you reduce admin, protect cash flow, and avoid costly mistakes.
