The Construction Industry Scheme (CIS) is a set of special rules that apply to contractors and subcontractors who work in the construction industry. The scheme is designed to ensure that contractors and subcontractors certify that their workers are paying the right amount of tax. If you are a contractor or subcontractor who works in the construction industry, you must register for the CIS. Once you are registered, you will be sent a monthly return that you must complete and return to HMRC. EfjConsulting can help you with your CIS monthly return UK.
