How to Register for the Construction Industry Scheme (CIS)

The Construction Industry Scheme (CIS) is a mandatory tax deduction scheme designed by HMRC for contractors and subcontractors working in the UK construction sector. Whether you're just starting out as a sole trader or running a growing construction business, registering for CIS can offer numerous benefits – including smoother tax management and enhanced credibility with clients.

In this guide, we’ll break down the steps you need to follow to register for CIS and why professional support can make all the difference.

[edit] What is the Construction Industry Scheme (CIS)?

CIS was introduced by HM Revenue and Customs (HMRC) to combat tax evasion in the construction industry. Under the scheme, contractors deduct money from a subcontractor’s payments and pass it directly to HMRC as advance payments towards the subcontractor’s tax and National Insurance.

CIS applies to:

• Self-employed workers
• Partnerships
• Limited companies
• Labour agencies and property developers working in construction

Failing to register for CIS can lead to higher tax deductions (30% instead of the standard 20%) and penalties from HMRC.

[edit] Why Should You Register for CIS?

Registering for CIS ensures that:

• You get paid with lower tax deductions (20% instead of 30%)
• You maintain HMRC compliance
• You improve your business reputation and increase your chances of winning contracts

Plus, with CIS registration, you can reclaim certain business expenses and potentially receive tax refunds if you’ve overpaid.
