Construction Industry Scheme (CIS): Simplified Compliance. Maximum Cash Flow.

Stop Worrying About Deductions. Start Focusing on Building Your Business.

For contractors and subcontractors in the construction industry, the mandatory Construction Industry Scheme (CIS) is one of the most complex and time-consuming administrative burdens. Non-compliance leads to severe penalties, distracting you from your core work.

Harding Accounting specializes in turning this mandatory scheme into a simple, automated process. As your 21st century accountant, we take care of absolutely everything related to CIS—from verification to filing—using seamless digital accounting tools.

Our service guarantees compliance, eliminates administrative stress, and frees you up to focus 100% on winning contracts and earning as much as possible. We make CIS simple.

The CIS Burden: What We Handle for You

The Construction Industry Scheme requires precise compliance from both contractors (who make payments) and subcontractors (who receive them). We manage this complexity for both roles digitally.

For Contractors:

You are legally required to manage verification, calculate deductions, and report accurately to HMRC monthly. Harding Accounting takes on 100% of this responsibility:

Subcontractor Verification: We take care of verifying every subcontractor with HMRC digitally, establishing the correct deduction rate (0%, 20%, or 30%) before payments are made.

Accurate Calculation & Deductions: We ensure all CIS deductions are calculated correctly and applied to your monthly payroll and payments.

Monthly Returns (CIS300): We handle the mandatory monthly electronic submission of your CIS return (CIS300) to HMRC, ensuring you meet the strict deadline and avoid penalties.

Payment Statements: We provide accurate, digital payment statements to all your subcontractors on time.

For Subcontractors:

We ensure you are registered correctly, deductions are accurately reconciled, and we manage your year-end self-assessment for maximum efficiency.
