So our sales tax =9.2% if I plug in the city tax 2.9% and county of 6.3% =9.2% for the sales tax group

some invoice amounts the sales tax will round up or down a penny.

But if I make a sales tax item of the 9.2% it is perfect.

Is there any way to fix this?

Will it mess up my TPT when filing each month because we collect a few more pennies than we should?

Thanks!
