How CIS Tax Refunds Work
Under the Construction Industry Scheme (CIS), contractors usually deduct tax from payments to subcontractors. Depending on your total income, allowable expenses and tax already deducted, you may have overpaid tax.
Tax refunds are not guaranteed. Eligibility and refund amounts depend on your individual circumstances, and HMRC determines the final tax position.
01 — Review Your CIS Deductions
We review your CIS deduction statements and income records to establish how much tax has already been deducted.
02 — Calculate Your Tax Position
We review your allowable business expenses and calculate your tax liability through Self Assessment.
03 — Claim Any Refund Due
If you have overpaid tax, we include the relevant information in your Self Assessment return and help you claim any refund due from HMRC.

Frequently Asked Questions About CIS Tax Returns
What is CIS and how does it work?
Under the Construction Industry Scheme (CIS), contractors deduct tax from payments to subcontractors and report these deductions to HMRC. The deductions count towards the subcontractor's tax and National Insurance liabilities.
Can I claim a CIS tax refund?
You may be entitled to a refund if the CIS tax deducted from your payments is more than your final tax liability. We can review your income, expenses and deductions to establish whether a refund is due.
What documents do I need for my CIS tax return?
You will normally need your UTR, National Insurance number, CIS deduction statements, income details and records of business expenses. We will guide you through the documents required.
How long does a CIS tax refund take?
HMRC processing times vary and additional checks can cause delays. We prepare and submit your return once we have the necessary information, but HMRC determines when any refund is issued.
What expenses can I claim as a CIS subcontractor?
Allowable expenses may include tools, protective clothing, qualifying travel, insurance and other genuine business costs, subject to HMRC rules.
What if my contractor has not provided CIS statements?
We can explain how to request missing CIS deduction statements and help you identify the information needed to support your tax return.
Can you help with overdue CIS tax returns?
Yes. We can help prepare outstanding Self Assessment tax returns involving CIS income. HMRC penalties and interest may apply to late returns or payments.
Can I use your service from anywhere in the UK?
Yes. SVS Accounting Services provides online CIS tax return and refund support throughout the UK, without requiring an office visit.
