For companies who operate within the UK Construction industry and qualify under HMRC rules for being a contractor, you must submit a monthly CIS return to HMRC indicating the corresponding CIS deductions taken from the subcontractor's payments in that month.

HMRC - What you must do as a Construction Industry Scheme (CIS) contractor

Step 1.

Navigate to the Tax > CIS > Returns menu.

Step 2.

Select a From date - this can be set as far back as you like to pick up missed payments. Select a To date - as per HMRC requirements, this should always be the 5th of each month.

Click on the Create return button to proceed.

Step 3.

The system will search for all bills with a CIS account and populate the return with payments allocated to these bills with the appropriate amount of CIS and materials.
