My client has a customer who is deducting CIS from the invoice we sent to him. It is a new build so not subject to VAT. I have spoken to Sage helpline and they advised me that Sage only handles CIS VAT deductions. I have looked at the Sage help information and that does not seem to be the case to me, as you can have reverse VAT or no VAT, so CIS is deducted from labour and materials as income tax or corporation tax in advance. The accountant advised me that the CIS deducted is recovered via the PAYE. Very unsure what to do regarding this client or the postings and not sure that the advice that Sage helpline gave me is correct. Any advice would be appreciated. Many thanks.
