CIS TAX Returns in Reading
If you’re working in the UK construction industry as a contractor or subcontractor, understanding your obligations under the Construction Industry Scheme (CIS) is essential. Incorrect or late submissions can lead to serious penalties from HMRC. At Interface Accountants, we provide a reliable and timely CIS returns service in Reading, helping you stay compliant, get paid correctly, and avoid any costly errors.

What is CIS and Who Does It Apply To?
The Construction Industry Scheme (CIS) is a tax deduction system put in place by HMRC for individuals and companies operating in the construction sector. Under CIS, contractors must deduct money from a subcontractor’s payments and pass it to HMRC. These deductions are treated as advance payments towards the subcontractor’s tax and National Insurance.
If you’re a contractor, it’s your legal responsibility to register for CIS, verify your subcontractors, and submit monthly returns. If you’re a subcontractor, you need to ensure your status is registered so you’re not overtaxed and can claim back what you’re owed. Our experienced team assists both contractors and subcontractors with accurate and efficient CIS tax returns in Reading.
