CONSTRUCTION INDUSTRY SCHEME (cis)
CIS Accountants UK - What Is the CIS Scheme?
The Construction Industry Scheme (CIS) is a tax framework set up by HMRC to regulate how payments are made to subcontractors in the construction sector.
Under CIS, contractors are legally required to deduct tax at source from subcontractors’ payments and pass it to HMRC on their behalf.
These deductions (usually 20% or 30%) act as advance payments toward the subcontractor’s income tax and National Insurance.
The issue? Many subcontractors overpay due to incorrect or excessive deductions — and that’s where we step in.
We simplify CIS compliance, deductions, and claims, helping construction professionals recover overpaid tax quickly and stay compliant with HMRC all year round.
At CIDB Solutions, we help you reclaim what’s rightfully yours by preparing and submitting accurate CIS tax refund claims — ensuring you get every penny you’re owed, without delay or errors.

Our digital process eliminates paperwork and speeds up turnaround times.

Monitoring claim progress – keeping you informed until your refund is processed.
Every stage is handled digitally — you’ll upload CIS statements and receipts securely via our encrypted client portal.
How We Maximise Your CIS Refund
CIS refunds are often delayed or reduced because many subcontractors don’t claim their full range of expenses.
At CIDB Solutions, our accounting experts analyse your CIS records in detail to ensure you claim every allowable cost — from mileage and tools to training, materials, and protective clothing.
We go beyond the basic claim, ensuring that:
All relevant expenses are included
Your self-assessment tax return reflects CIS correctly
You avoid under- or over-reporting income
You receive the maximum refund possible

Frequently Asked Questions
What is the Construction Industry Scheme (CIS)?
The Construction Industry Scheme is a system created by HMRC to regulate how contractors pay subcontractors in the construction sector. Under CIS, contractors must deduct a portion of the subcontractor’s payment (usually 20% or 30%) and submit it directly to HMRC as an advance payment toward the subcontractor’s tax.
Who needs to register under CIS?
Anyone working in the UK construction industry — as a contractor or subcontractor — must register with HMRC under CIS.
Contractors are responsible for deducting and reporting tax.
Subcontractors have deductions taken from their pay but can claim refunds if they’ve overpaid.
We can register you for CIS and manage all submissions on your behalf.
How can I claim a CIS tax refund?
If you’re a self-employed subcontractor, your CIS deductions often exceed your actual tax liability. You can claim a refund by filing a Self Assessment Tax Return.
At CIDB Solutions, we review your income, expenses, and CIS statements to calculate your refund accurately and ensure you receive the maximum amount you’re entitled to — usually within a few weeks of filing.
What documents do I need for a CIS claim?
You’ll need:
CIS deduction statements (from each contractor)
Invoices or payment summaries
Proof of expenses (fuel, tools, materials, PPE, etc.)
UTR number and National Insurance number
If you’re missing any records, don’t worry — we can contact contractors and HMRC to help retrieve them before submission.
How long does it take to receive a CIS refund?
Most CIS tax refunds are processed within 2–6 weeks, depending on HMRC’s workload and the accuracy of your records. Because we prepare and submit claims digitally through our secure CRM system, your refund is handled quickly, safely, and efficiently.
Can limited companies also claim CIS refunds?
Yes. Limited companies working under CIS can offset deductions against their monthly or quarterly PAYE liabilities, or request refunds at the end of the tax year.
We manage the entire process — from verifying CIS statements to liaising directly with HMRC to recover any overpaid amounts.
