Cis Services You Can Trust. Ensure compliance with ACG.
Comprehensive CIS Services for Contractors and Subcontractors
If you work in construction in the UK, you already know that the Construction Industry Scheme (CIS) can be complicated. Whether you’re a contractor, subcontractor—or both—staying compliant with HMRC’s CIS services regulations is crucial. That’s where Audit Consulting Group steps in.
We provide expert, end-to-end CIS services designed to simplify compliance, avoid penalties, and ensure you get every penny you’re entitled to. From registrations to returns, verifications to deductions—we’ve got you covered.
What Are CIS Services?
The Construction Industry Scheme (CIS) is a set of rules from HMRC that governs how payments are made between contractors and subcontractors in the construction industry. Under CIS, contractors must deduct money from payments to subcontractors and pass it to HMRC.
Our CIS services ensure:
- Proper registration and setup with HMRC
- Accurate monthly CIS returns
- Subcontractor verification
- Deduction statement generation
- Reclaim of overpaid CIS tax (especially for subcontractors)
- Advice on whether CIS applies to your work
- Peace of mind for both contractors and subcontractors
Who Needs CIS Services?
You need CIS services if you are:
- A contractor who pays subcontractors for construction work
- A subcontractor providing labour or services to a contractor
- A business that does both (common in building and maintenance firms)
Whether you are an individual sole trader or a company managing large projects, CIS compliance is mandatory. We help you get it right, every month.

Case Studies – Real Help for Real Businesses
Case 1: Contractor Avoids Late Filing Penalties
A small construction firm in Birmingham came to us after missing two CIS returns. HMRC penalties were piling up. We stepped in, contacted HMRC, and submitted backdated returns with a reasonable excuse. Penalties were waived, and the client is now 100% compliant with our monthly CIS service.
Case 2: Subcontractor Gets £7,200 Tax Refund
A self-employed subcontractor working across various sites had 20% deductions made throughout the year. After reviewing his records and completing his Self Assessment, we claimed a refund of £7,200 from HMRC within three weeks.
Case 3: Gross Payment Status Application
A medium-sized subcontracting business wanted to improve cashflow. We applied for gross payment status, ensured eligibility, and liaised with HMRC through the approval process. Within 6 weeks, they were approved—boosting cashflow by 20% each month.
What Happens If You Ignore CIS?
Failure to comply with CIS obligations can result in:
- Monthly penalties of £100 per missed return
- Additional fines for incorrect filings
- Withholding of tax refunds by HMRC
- Delays in cashflow
- Risk of investigation
Our clients avoid these issues entirely by letting us handle their CIS administration.

Frequently Asked Questions (FAQ)
What is the Construction Industry Scheme?
CIS is a UK tax scheme where contractors deduct money from subcontractors’ payments and pass it to HMRC. It helps ensure taxes are collected in the construction sector.
What happens if I don’t register for CIS?
Contractors who aren’t registered can be fined. Subcontractors will have 30% deducted from their payments instead of 20%. Registration helps both parties stay compliant.
How do I get gross payment status?
You must apply to HMRC and meet certain conditions (e.g., proper tax history, turnover). We’ll assess your eligibility and apply on your behalf.
I work as both a contractor and subcontractor. Is that a problem?
Not at all. Many businesses do both. We can register and manage your CIS status for each role accordingly.
Can you help me get a CIS tax refund?
Yes. If you’re a subcontractor and have had deductions made throughout the year, we’ll review your records, file your tax return, and claim back any overpaid tax.
How much do your CIS services cost?
Our CIS services start from an affordable fixed monthly rate. We also offer bespoke packages for larger firms. Contact us for a no-obligation quote.
