Your machine has an automatic tax calculation feature which allows you to program four tax tables to avoid
calculating incorrect tax amounts.
Automatic tax calculations require you to program, in addition to the tax table, the tax status of each pertinent
department, PLU, and function key.
The tax table (applicable to the add-on tax)
Sample tax table
New Jersey tax table: 6%
To program a tax table, first make a table like the right table shown above.
From the tax table, calculate the differences between a minimum break point and the next one (A). Then, from
the differences, find irregular cycles (B) and regular cycles (C and D). These cycles will show you the following
items necessary to program the tax table:
T: The tax amount collected on the minimum taxable amount (Q)
Q: The minimum taxable amount
M1: The maximum value of the minimum breakpoint on a regular cycle (C).
We call this point “MAX point.”
M2: The maximum value of the minimum breakpoint on a regular cycle (D).
We call this point “MAX point.”
M: Range of the minimum breakpoint on a regular cycle: difference between Q and M1 or between M1 and
M2
