View CIS

I'm a sole trader enroled in the CIS scheme. I use the CIS code on relevant invoices so as to provide invoices showing gross and net of deductions values. I cannot find a report anywhere showing what CIS I have suffered. I saw somewhere about using the TAX tab but I do not have that tab available. ANy suggestions or is there another way to view my CIS account. Thanks in advance and I hope that all made sense. Chris
