Letter of Representation – CIS Returns

About this document

What it’s for

An annual letter from a contractor to your firm covering the CIS monthly returns you prepare and submit: who was paid, verification, the employment status declaration, labour and materials, deduction rates, nil returns and supply chain checks – plus deductions suffered as a subcontractor. A monthly approval slip is included, with firm guidance, a tailoring table and a checklist.

When to use it

  • Once a year for each CIS contractor client
  • With the slip before each monthly return
  • When a client starts as a contractor or applies for gross payment status
