How to Claim CIS Refunds for UK Limited Companies

The Construction Industry Scheme (CIS) is a tax mechanism for contractors and subcontractors in the construction sector. If you’re a limited company subcontractor under CIS, you may be entitled to claim back deductions made by contractors from your payments. Here’s a very handy guide on how to make a CIS claim and ensure your tax affairs are in order.

Who Can Claim a CIS Refund?

Limited companies operating as subcontractors can claim back CIS deductions if:

  • Excess tax or National Insurance contributions have been paid.
  • They have submitted all necessary PAYE, Corporation Tax, and VAT information.

For sole traders, CIS deductions are offset through the Self-Assessment process.

What You Need for Your CIS Claim

To file a CIS refund claim, you will need:

Business Details:

Company name, address, PAYE reference, and Corporation Tax Unique Taxpayer Reference (UTR).

Financial Records:

Evidence of CIS deductions, such as Payment and Deduction Statements (PDS) from contractors.

Bank Details:

For direct payments, provide your bank account number, sort code, and account name.

If claiming on behalf of another party (e.g., using an agent), complete the R38 form or submit equivalent authorization​
