Why does the refund have a different rate than the original sale?
The tax amount on your original sale and the refund are different and you want to know why.
Transactions processed prior to using the Avalara service were not calculated using our rates, refunds processed in our system are not expected to have the same tax rate of the original sales calculated outside of Avalara.
Why does the tax not change when I change from Line to Document Level Rounding?
