CIS Processing
Updated
by Caroline Buckland
Overview
The Construction Industry Scheme (CIS) is a tax scheme in the United Kingdom that allows contractors and subcontractors in the construction industry to manage their tax affairs more easily. It was introduced by HM Revenue & Customs (HMRC) to simplify the way taxes are handled in the construction industry.
Here's a brief overview of the CIS:
Key features:
- Registration: Contractors and subcontractors must register with HMRC to use the CIS.
- Tax deductions: Contractors deduct taxes from payments made to subcontractors and pay them over to HMRC.
- Subcontractor status: Subcontractors can choose to be registered as either exempt (no tax deductions) or standard (tax deductions are made).
- Payment terms: Contractors must pay subcontractors within 30 days of receiving payment from the client.
Benefits:
- Simplified tax administration: The CIS reduces the administrative burden on contractors and subcontractors.
- Reduced tax compliance: Contractors and subcontractors can focus on their core business, rather than dealing with complex tax issues.
- Improved cash flow: The CIS helps ensure that subcontractors receive payments on time.
Types of CIS schemes:
- CIS Standard: This is the most common scheme, where contractors deduct taxes from payments to subcontractors.
- CIS Exempt: Subcontractors can choose to be exempt from tax deductions, but they must still register with HMRC.
- CIS Self-Certification: This scheme allows subcontractors to self-certify their status, reducing the need for contractors to make tax deductions.
