Assessing: SAGE: recording calculation details

When you issue a calculation for tax and/or interest, information about the calculation needs to be input to SAGE. This is either done automatically (IHTM31862) for COMPASS calculations, or manually for Template calculations when you send copies to Accounts Section.

SAGE records the tax and interest due separately against each file reference. This means that for a single calculation SAGE records two transactions, one for the tax and another for the interest.

When a calculation is withdrawn, a credit note is entered on the system. Again, tax and interest are recorded as two separate transactions.
