CIS TAX Returns in Uxbridge
If you’re a contractor or subcontractor working in the construction industry, you must comply with the Construction Industry Scheme (CIS) as required by HMRC. At Interface Accountants, we specialise in managing CIS returns in Uxbridge for businesses and individuals, ensuring every deduction, payment, and filing is handled accurately and on time. Our tailored support helps you stay on top of your CIS obligations while avoiding costly penalties.
Whether you’re a contractor hiring subcontractors or a self-employed subcontractor submitting your own claims, our CIS returns service in Uxbridge ensures you remain compliant while maximising your entitlements.

Understanding CIS and Your Obligations
The Construction Industry Scheme requires contractors to deduct money from subcontractors’ payments and pass it to HMRC. These deductions count as advance payments toward the subcontractor’s tax and National Insurance. The system is designed to reduce tax evasion in the industry, but it often adds a layer of complexity to your accounting.
Our experienced team works with builders, electricians, plumbers, roofers, and other trades across Uxbridge who are registered under CIS. We make sure your records are in order and your returns are submitted correctly — whether monthly, quarterly, or annually.
