Managing payments to subcontractors under the Construction Industry Scheme (CIS) is a legal requirement for contractors in the UK construction sector. However, the process can quickly become complex and time-consuming — involving verification, tax deductions, monthly returns, and strict HMRC compliance.

Infinity Group is a trusted name in construction payroll solutions, offering professional CIS payroll services tailored for contractors, developers, and trade businesses across the UK. With deep knowledge of CIS rules and years of experience in the field, we ensure your payroll is accurate, compliant, and stress-free.

Why CIS Payroll Matters

Under the HMRC Construction Industry Scheme, contractors are required to:

• Verify each subcontractor’s status with HMRC

• Deduct tax at source (typically 20% for registered subcontractors, 30% for unregistered)

• File monthly CIS returns with HMRC

• Issue detailed payment and deduction statements to subcontractors

• Maintain accurate records for inspections or audits

Failure to follow these rules can result in heavy penalties, cash flow issues, and reputational risk. That’s why more UK contractors are turning to CIS payroll experts like Infinity Group.

Our CIS Payroll Service

At The Infinity Group, we provide a fully managed CIS payroll service that ensures your subcontractor payments are processed accurately and on time, in full compliance with HMRC requirements.

Our service includes:

Subcontractor Verification

We verify each subcontractor with HMRC and apply the correct deduction rate (20% or 30%) based on their registration status. This ensures legal compliance and reduces the risk of over- or under-deduction.

Accurate Deduction Calculations

Our team handles the full calculation of CIS deductions, taking into account bonuses, adjustments, and specific job arrangements to ensure precision in every payment.

Monthly CIS Returns

We prepare and submit your monthly CIS300 return to HMRC, ensuring it’s accurate, complete, and filed before the deadline — avoiding penalties and delays.

Deduction Statements and Payslips

We generate detailed deduction statements for each subcontractor, including gross payment, tax withheld, and net amount paid. These documents support subcontractors in managing their own tax records.

Digital Record Keeping and Reporting

All payroll information is securely stored in a cloud-based system. You’ll have access to downloadable reports, audit trails, and payment summaries for full transparency and compliance.

Optional Payment Processing

If required, we can process subcontractor payments on your behalf through secure banking systems, streamlining your payment workflow even further.
