CIS Refund Services
Claim What’s Rightfully Yours. Fast, Accurate, and Fully Compliant CIS Refund Support.
What is a CIS Refund?
The Construction Industry Scheme (CIS) is a UK tax system where contractors deduct money from subcontractors’ payments and pass it to HMRC. These deductions count as advance payments towards the subcontractor’s tax and National Insurance.
If you’ve had too much tax deducted under CIS, you’re entitled to claim a CIS refund. At Edge Outsource, we help subcontractors and limited companies in the construction industry recover overpaid CIS deductions—accurately, efficiently, and stress-free.

We assess your earnings, deductions, and tax status to determine if you’re due a CIS tax refund—and estimate how much you could receive.
2. Document Preparation & SubmissionWe handle all the necessary documentation and HMRC submissions for your tax return, ensuring full compliance and maximizing your refund.
3. Fast-Tracked ProcessingWe file your CIS refund claim promptly and monitor the progress to ensure the quickest possible turnaround time from HMRC.
4. Self-Employed & Limited CompaniesWhether you’re a sole trader or running your business through a limited company, our experts are experienced in handling both.
