Sterling Books offer a full CIS Returns Service for Contractors and Sub-contractors.

Under the Construction Industry Scheme (CIS), contractors must make deductions from the payments made to their subcontractors for tax and National Insurance purposes. These deductions are spread out over time instead of a large sum being owed at the end of the tax year.

Requirements for Contractor Registration with CIS:

As a contractor, before employing a subcontractor, you must register for CIS with HMRC. During this process, you’ll be classified as a new employer and will receive a PAYE reference number.

Once you’ve registered for CIS and confirmed the status of your subcontractors, it will be your responsibility to withhold a portion of their pay for Income Tax and National Insurance. It is important to be aware of the status of the workers you engage with, as misclassifying an employee as a subcontractor can result in penalties.

Requirements for Subcontractors

To sign up for the Construction Industry Scheme, subcontractors can complete the process online using their Government Gateway ID and password, as well as their UTR number. While registering for CIS is optional, doing so can result in a 10% reduction in your tax bill as deductions from your payments will be taken at a lower rate.
