Factored Tax

When a business “factors” transaction privilege tax, it means the tax is included in the total price rather than shown as a separate charge. If you choose to factor the tax, the tax must be calculated using a factoring formula.

There are many different factoring formulas depending on city taxes, county taxes or differences in allowable city tax deductions. Here is a helpful worksheet to assist you in factoring tax. 

See Arizona Transaction Privilege Tax Procedure TPP 00-1 for information about factoring.
