AZ HB2109

Amends section 42-6106 of Arizona Revised Statutes to increase the maximum county transportation excise tax rate from 10 percent to 20 percent of the applicable transaction privilege tax rate.

The increased rate applies to taxes on business transactions and utility consumption (electricity and natural gas), provided any combined tax imposed under sections 42-6106 and 42-6107 does not exceed 20 percent.

Requires voter approval at a countywide election before the regional transportation authority can levy the tax, with rates specified in the ballot proposition.

Net revenues are deposited into transportation funds: the regional transportation fund in counties exceeding 400,000 persons, or the public transportation authority fund and/or regional transportation fund in smaller counties.

Tax remains effective for a maximum period of 20 years, beginning January 1 or July 1 following voter approval.
