For example, part of a tax table might look like:
In our Example Tax Chart, a sale from .00 to .08 is not taxed. The next tax bracket a
sale from .09 to .24 is taxed one cent. The next tax bracket a sale from .25 to .41 is
taxed two cents. The tax table progresses in a similar manner.
To calculate your tax rate
1 Using The Worksheet on page60, complete Step A with the appropriate
amounts from your state's Retail Tax Chart.
2 For the following, see the Example Tax Chart, Step B:
The difference between the starting amounts of each consecutive tax bracket is
called a breakpoint. Every tax table consists of a particular sequence of
breakpoints.
In our Example Tax Chart, the difference between .00 and .13 is .13 cents. This 13
is the first breakpoint. The difference between .13 and .32 is .19 cents, which means
19 is the second breakpoint.
The breakpoints continue in a particular sequence through the entire tax table.
Using The Worksheet, complete Step B by calculating the breakpoints based

on your state's Retail Tax Chart.
The sequence of breakpoints is divided into Regular and Irregular patterns.

All tax tables have a pattern of irregular breakpoints that leads into a
repeating pattern of regular breakpoints.
To determine the breakpoint pattern, continue calculating the breakpoints in
Part B until you have found the Regular repeat breakpoint pattern.
From our example:
Breakpoints 13, 19, 23, 27, 27, 29 are the Irregular breakpoint pattern. Breakpoints
25, 25, 25, 25 are the Regular repeating breakpoint pattern.
The Regular repeating breakpoint pattern is a point where you first see a repetition of
one or more numbers, which then add up evenly to 100, 200, 300, and so on.
In our programming example, the Regular breakpoint pattern (25, 25, 25, and 25)
adds up to 100.
