What is a CIS tax return?

The Construction Industry Scheme (CIS) is a HMRC scheme that governs how contractors must handle payments to subcontractors. Under CIS:
  • Contractors must deduct money from subcontractors’ payments and pass it to HMRC.
  • Subcontractors can claim back deductions when filing their annual tax return.
  • Filing mistakes or late submissions can lead to costly penalties.
Our CIS Tax experts handle the process end-to-end, ensuring every figure is accurate and submitted on time.
