UK Construction Industry Scheme setup

This is really a question for Sage, but any assistance would be appreciated.

HMRC in the UK recently changed how CIS VAT was calculated, and therefore reported.

I was wondering whether there was any documentation, processes, setup information, on how to meet the HMRC requirements for reporting CIS.

I know it's a reverse charge, but how do you deal with the 5% part of the requirement.

Thanks

Martin
