Taxation in Stax Bill and Avalara has typically calculated on a per charge/line item as well as a per tax basis.
The taxes will be calculated individually, and then added up. This means that rounding can take place on each of those.
For Example:
- A product charged in San Antonio, Texas could have the following tax calculations on it:
- The product is 4.99
- Texas State Tax of 0.0625% $0.31
- San Antonio City Tax: 0.0125% $0.06
- San Antonio MTA Transit Special Tax: 0.005% $0.02
- San Antonio ATD Transit Special Tax: 0.0025% $0.01
- While this adds up to a rate of %0.0825
- The total taxed amount will be 0.31+0.06+0.02+0.01 = $0.40
- Which will differ from what would be otherwise expected: $0.41
