CIS Accounting Made Simple for Contractors & Subcontractors
The Construction Industry Scheme (CIS) can be complex, requiring contractors and subcontractors to manage monthly submissions, tax deductions, and HMRC compliance. At AMAccountex LTD, we specialize in CIS accounting services, ensuring that you stay compliant, avoid penalties, and streamline your financial management.
Whether you’re a contractor, subcontractor, or self-employed construction worker, our CIS experts provide tailored accounting solutions that save you time and money.
What is the Construction Industry Scheme (CIS)?
The Construction Industry Scheme (CIS) is a set of regulations introduced by HM Revenue & Customs (HMRC) to ensure that tax deductions from subcontractor payments are handled correctly. Under CIS, contractors deduct tax at source from payments made to subcontractors and pass it on to HMRC. This ensures that subcontractors meet their tax obligations and reduces tax evasion in the construction industry.
Who Needs to Register for CIS?
Contractors: Businesses or individuals who pay subcontractors for construction work must register for CIS and handle tax deductions before making payments.
Subcontractors: If you work under a contractor in the UK construction industry, you may have 20% tax deducted at source (or 30% if unregistered).
Self-Employed Workers: Even if you work for multiple clients, you must register under CIS to avoid higher tax deductions.
Failure to comply with CIS regulations can result in heavy penalties, interest charges, and HMRC investigations.

Our CIS Accounting Services
At AMAccountex LTD, we provide a complete CIS accounting solution to help contractors and subcontractors manage their obligations smoothly.

We handle the entire CIS registration process, ensuring you are correctly set up with HMRC. Our experts provide:
✔ CIS registration assistance for contractors & subcontractors
✔ Verification of subcontractors with HMRC CIS online services

2. CIS Monthly Returns & HMRC Submissions
Every month, contractors must submit a CIS return to HMRC detailing payments made to subcontractors. Our CIS accountants will:
✔ Prepare and submit CIS monthly returns before the 19th of each month
✔ Ensure correct tax deductions (20% or 30%) to avoid penalties
✔ Verify subcontractor employment status to prevent compliance risks
Missed a CIS deadline? HMRC issues fines for late submissions. Our team will ensure you never miss a CIS deadline again.

✔ Ensure you receive a fast CIS rebate from HMRC
We have successfully helped hundreds of subcontractors claim their CIS refunds, often recovering thousands of pounds each year.
