Am now into my second year of using the Tax Calc AML module. I like to update CDD for my clients every 12 months (or when I prepare their Tax Returns, accounts, etc.). I know that IRIS uses a 'check box' system to indicate that the client has been re-checked and there are no changes. Tax Calc doesn't seem to have this facility. What procedures have you adopted on TC AML to indicate you've updated the CDD?
