AZ HB2439

Amends Arizona's individual income tax code to establish annual adjustment of tax bracket income thresholds beginning in taxable year 2014.

Requires the Department of Revenue to adjust income dollar amounts for each tax rate bracket according to the average annual change in the metropolitan Phoenix consumer price index published by the U.S. Bureau of Labor Statistics.

Adjustments to bracket thresholds must be rounded to the nearest whole dollar and cannot be reduced below the amounts prescribed in the prior taxable year.

Establishes a baseline tax structure with five rate brackets for single filers and married couples filing jointly, with rates ranging from 2.59% to 4.54% of taxable income.
