Specialist CIS Tax Returns for UK Contractors and Subcontractors

The Construction Industry Scheme (CIS) is a HMRC system where contractors deduct tax at source from subcontractors’ payments and pass it to HMRC. It helps ensure that tax is collected correctly within the construction industry.

If you are a contractor paying subcontractors, you must register for CIS and submit monthly returns. Subcontractors can also register to reduce the tax deducted from their payments. We can help with the registration process for both.

Each month, you must report the payments you have made to subcontractors and the deductions taken. We prepare and submit this return to HMRC on your behalf, ensuring accuracy and compliance.

A CIS return covers payments made to subcontractors during the tax month, which runs from the 6th of one month to the 5th of the next. For example, the return due by 19 July would cover the period from 6 June to 5 July.

CIS returns are due by the 19th of each month for the previous month’s payments. Late submissions can result in penalties from HMRC, which we help you avoid by managing deadlines for you.
