Construction Industry Scheme (CIS) Services

Stay Compliant. Get Paid. Be Tax-Ready.

It’s more important than ever for contractors and subcontractors in the construction industry to stay fully compliant with the Construction Industry Scheme (CIS). At Perpetual Accountancy, we make it simple.

Whether you’re a contractor managing multiple trades or a subcontractor working job to job, our CIS specialists ensure you’re ticking every HMRC box—accurately and on time.


What is the Construction Industry Scheme (CIS)?

CIS is a set of rules from HMRC for contractors and subcontractors in the construction industry. It requires contractors to deduct money from subcontractors’ payments and pass it to HMRC. These deductions count as advance payments towards the subcontractor’s tax and National Insurance.
