I recently received my first IRP 501, "Reconciliation of tax deductions and certificates."

Looks like I need an IRP5 book (which thankfully my accountant has organised), and then I need to reconcile the tax paid to the amounts on the IRP5 certificates (which will be issued). Also seems that I have to declare the numbers of the IRP5 certificates issued.

Seems relatively straight forward....anyone want to walk me through what needs to be done? Or possibly point out anything which can be an issue?
