Prop 479 extends Maricopa country transportation tax to 2045
Oct. 1
Prop 479 is the extension of the Maricopa County Transportation Tax, which is the continuation of an existing, dedicated half-cent sales tax in Maricopa County to fund transportation.
This dedicated half-cent sales tax was first established by voters in 1985 with the approval of Proposition 300 and subsequently renewed in 2004 with the voters’ approval of Proposition 400.
Its extension is on the November 5, 2024, Maricopa County ballot. A “yes” vote extends the tax until 2045. A “no” vote will discontinue the tax at the end 2025.
