Managing finances as a contractor or construction business owner is rarely straightforward. Between verifying subcontractors, tracking deductions, and filing monthly returns, the Construction Industry Scheme (CIS) adds a layer of complexity that many businesses find difficult to handle alone. Get it wrong, and you risk penalties from HMRC. Get it right, and you protect your cash flow, your compliance, and your reputation. That’s where a dedicated CIS accountant makes all the difference. At Gowin Accountants Ltd, we specialise in providing professional accounting services to contractors, freelancers, and businesses across England. With over 10 years of experience in business and financial management, our team is built around one goal: making your accounting seamless, so you can stay focused on the work that matters most.
What Is the Construction Industry Scheme (CIS)?
The Construction Industry Scheme is a set of HMRC rules that govern how payments are made between contractors and subcontractors in the construction industry. Under CIS, contractors must deduct money from a subcontractor’s pay and pass it to HMRC. These deductions count as advance payments towards the subcontractor’s tax and National Insurance.
CIS applies to a wide range of work, including:
- Building and demolition
- Alterations and repairs
- Installing systems (e.g., heating, lighting, water)
- Civil engineering projects
- Site preparation and cleaning
Both contractors and subcontractors must register with HMRC under CIS. Failure to do so—or errors in filing—can result in significant financial penalties.
What Does a CIS Accountant Actually Do?
A CIS accountant manages the full scope of your Construction Industry Scheme obligations. Rather than treating CIS as an afterthought, a specialist firm like Gowin Accountants Ltd integrates CIS compliance into your broader financial management strategy.
Here’s what a professional CIS accountant handles:
- Contractor registration with HMRC under CIS
- Subcontractor verification to confirm the correct deduction rate
- Monthly CIS returns filed accurately and on time
- Deduction statements issued to subcontractors
- CIS tax refund claims to ensure you’re not overpaying HMRC
- Bookkeeping and reconciliation of CIS payments within your accounts
- Year-end accounts and self assessment or corporation tax filings
For contractors operating as limited companies or sole traders, this kind of hands-on support removes the administrative burden and significantly reduces the risk of non-compliance.
Why CIS Compliance Matters for Your Business
HMRC takes CIS seriously. Contractors who fail to file monthly returns on time face an automatic £100 penalty—and that figure rises the longer a return remains outstanding. In some cases, penalties can reach thousands of pounds for persistent non-compliance.
Beyond penalties, poor CIS management can cause cash flow problems. Subcontractors who have had deductions taken incorrectly may struggle to claim refunds, while contractors who haven’t verified their subcontractors may be applying the wrong deduction rates entirely.
Working with an experienced CIS accountant protects your business on both fronts. Gowin Accountants Ltd ensures your CIS obligations are met every month, with no missed deadlines and no guesswork.

Frequently Asked Questions – CIS Accountant
What is a CIS accountant and what do they do?
A CIS accountant specialises in managing Construction Industry Scheme obligations for contractors and subcontractors. Their responsibilities include registering businesses with HMRC, verifying subcontractors, filing monthly CIS returns, issuing deduction statements, and claiming CIS tax refunds. Gowin Accountants Ltd provides all of these services as part of a fixed-fee package for clients across England.
Do I need a CIS accountant if I’m a sole trader?
Yes. Sole traders operating as contractors or subcontractors under CIS still have the same compliance obligations as limited companies. A CIS accountant ensures your deductions are correct, your returns are filed on time, and any overpaid tax is reclaimed efficiently.
How much does a CIS accountant cost?
Costs vary between firms. Gowin Accountants Ltd offers transparent, fixed monthly fees with no hidden charges, making it easier to budget for professional accounting support. Contact the team on 01256 578106 or visit gowinaccountants.co.uk for a personalised quote.
What happens if I don’t file my CIS return on time?
HMRC imposes automatic penalties for late CIS returns. A return filed one day late incurs a £100 penalty, rising to £200 after two months, and up to £3,000 for returns that are 12 months or more overdue. Working with a specialist CIS accountant eliminates this risk by ensuring all returns are submitted accurately and on time.
Does Gowin Accountants Ltd work with businesses outside Basingstoke?
Yes. Gowin Accountants Ltd provides CIS accounting services and broader financial management support to contractors and businesses across the whole of England—not just Basingstoke.
Can a CIS accountant help me claim a CIS tax refund?
Yes. If more tax has been deducted under CIS than you actually owe, you’re entitled to claim a refund from HMRC. Gowin Accountants Ltd manages this process on your behalf, ensuring you recover any overpayments promptly.
