I'm here to ensure you can register for the Construction Industry Scheme (CIS), Ed. Let me share where you can do it to get you started.
Please know that you need to register CIS directly with the HMRC. You'll want to visit their website through this link for further guidance: What you must do as a Construction Industry Scheme (CIS) subcontractor: How to register - GOV.UK.
After that, enable the CIS in QuickBooks to begin calculating and deducting amounts from a subcontractor’s payments as part of their tax and National Insurance obligations.
Moreover, refer to this material for the complete instructions on creating CIS transactions, submitting them to HMRC, and generating related reports to review corresponding data: CIS guide in QuickBooks.
