CIS (Construction Industry Scheme) Refund Form Guidance
Working in the construction industry in the UK means dealing with the CIS (Construction Industry Scheme). For contractors and subcontractors alike, it’s essential to understand how CIS deductions work, how to stay compliant with HMRC rules, and how to file for a tax refund using the cis refund form.
At Audit Consulting Group, we provide specialist CIS support – helping subcontractors reclaim overpaid tax, ensuring contractors make the correct deductions, and guiding businesses through every HMRC requirement.
What Is CIS?
The CIS is a scheme set up by HMRC to regulate how tax is deducted from payments made to subcontractors in the construction industry.
- Contractors deduct tax at source from payments made to subcontractors.
- Subcontractors can offset these deductions against their tax liability.
- Overpayments are refunded by HMRC, often claimed using the cis refund form.
Without professional help, many subcontractors overpay tax or face delays in getting their refunds.
CIS Refund Form – Claiming Back Overpaid Tax
The cis refund form is used by subcontractors to reclaim tax that has been over-deducted under CIS. Refunds can amount to thousands of pounds, particularly for workers with high expenses or those on lower incomes.
We help clients:
- Complete the cis refund form accurately.
- Provide the right evidence (payslips, invoices, expense receipts).
- Liaise with HMRC to ensure fast processing.
Most refunds are received within 4–8 weeks when handled correctly.
Why CIS Is Complicated
- Contractors must verify subcontractors with HMRC.
- Different tax rates apply (20% for registered, 30% for unregistered subcontractors).
- Subcontractors often don’t understand how deductions affect their annual tax position.
- Filing the wrong figures delays refunds.
Our CIS experts simplify the whole process – for both contractors and subcontractors.
