How much is your business spending on sales tax? QuickBooks has two reports which shows the information you are looking for.
The Sales Tax Liability report summarizes the sales tax you have collected and how much you owe each tax agency. The reports lists total taxable sales, total non-taxable sales, and the amount you owe each agency.
The Sales Tax Revenue Summary report shows the sales by tax agency sorted by taxable sales, non-taxable labor, and non-taxable sales.
