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.

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.

Click on the Lock payments and save CIS Return button to save the return. Once saved the payments appearing on the return will not be picked up in any future return, the return can then also be submitted to HMRC.
