Construction Industry Scheme Reform Manual

Deductions: overview: introduction

This paragraph is an overview of the arrangements for allowing credit or making repayments for deductions made under the Construction Industry Scheme.

The section covers the general arrangements for dealing with credits for CIS deductions. It outlines the legal basis and the general principles of the deductions process and the claims procedures for subcontractors seeking credit or repayment for deductions made. It also covers the detail on handling specific non-standard claims and cases.

Generally, there are two types of repayment that you will encounter; in-year repayment and standard end of year repayment on submission of the subcontractor’s SA return, or form P35 (for non RTI years), or Employment Payment Summary (EPS) returns (for RTI years), where the subcontractor is a company. In-year repayments may be made informally where a deduction has been made in error or formally under the provisions of SI2005/2045 reg 17.
