TAXATION MANAGEMENT USING ASYCUDA++ Ó UNCTAD - SITE (V1.15) A.10 Creating Taxation Columns ·     Column Label - is the column title. It contains the name of a tax. Insert column labels in the order in which they are to appear in the tariff on-screen display. The   maximum   number   of   columns   is   99.   Columns   1   to   15   are   set   up   in MODCHQCF and additional columns are created in  MODCHQ. See Section 10 of this Reference Document for more details on creating additional columns. ·     Priority - assigns a priority to the tax, according to the sequence in which the taxes within the columns are calculated. In setting priorities, values between 01 and 99 are acceptable. Certain taxes include other taxes in their Tax Base. An example is VAT (Value Added Tax), which would include the Customs Duty in the VAT tax calculation. ASYCUDA ++ must calculate the Customs Duty first, so 'Customs Duty' is given a higher priority than VAT. Taxation Rates Taxation column boxes contain the rates of taxes applying to a Commodity Code.  Rates are in a numeric format  (e.g. 10), or as a  General Note such as "VAT" or "EX", instead of a numeric tax rate.  The  use  of  codes  to  represent  commonly  used  tax  rates  is  explained  below  in   "Common Rates of Tax". Tax rates are placed directly into the taxation columns through MODCHQ. How the System Accesses Taxation Rates Using  Rules  to  modify  or  update  existing  taxation  calculations  means  that  ASYCUDA  needs  to know the original amount or rate that was calculated. Rates can be 'looked up' by a Rules Function such as Rate(Commodity Code). When rates are looked up by the Function Rate(Commodity Code) or similar, the System uses the rate that is in the column to which the rate is attached, i.e. rate 01, 02, 03, 04 etc. Rates are aligned to   the   column   order,   or   place   in   the   National   Tariff   List.   For  'recognising'   rates,   the   column description or headings is of no relevance. Important:    To    avoid    damaging    an    existing    tariff    structure,    any additional taxes must be added at the bottom of the list, after existing taxes. Extra care must be taken when deleting columns.
