State Tax Legislative Updates — Arizona, Colorado & New Mexico

2022 Legislative Session Updates — State Taxes in Arizona, Colorado, and New Mexico

Changes to state tax laws enacted during 2022 legislative sessions, so far, in the states of Arizona, Colorado, and New Mexico have meaningful implications for taxpayers and, in some cases, may potentially reduce tax liabilities.


Maricopa County Superior Court struck down a voter-approved income tax increase on high earners, Proposition 208, on March 11, 2022.

New call-to-action

Proposition 208, which has been entangled in litigation since voters passed it in 2020, imposed a 3.5% surcharge on taxable income above $250,000 for individuals and $500,000 for joint filers or heads of households to fund education and was struck down by Maricopa County Superior Court Judge John Hannah.

Hannah ruled on the narrow question of whether the new school funding would exceed annual spending limits, which the Arizona Supreme Court said would make the measure invalid.

The Superior Court “is obligated to strike down Proposition 208″ based on the state Supreme Court’s reasoning, Hannah wrote.

Arizona Department of Revenue has released a statement that they are working on updating the individual income tax forms and the administrative system in response to the ruling. For taxpayers that have already filed an Arizona individual income tax return, no action is required. The Department will hold returns with the surcharge and will process them correctly once their systems have been updated, removing the surcharge and correcting tax bracket rates. The Department has advised taxpayers who have not yet filed to use the current form following the current instructions. The Department will make the necessary changes to these returns as well, once they have updated their systems.


Colorado Governor Jared Polis signed a law regarding the exception to the sales and use tax destination sourcing requirement for Colorado retailers with less than $100,000 in annual retail sales. The law, which took effect January 31, 2022 extends the exception’s sunset date from February 1, 2022 to October 1, 2022.


On March 8, 2022 New Mexico Governor Michelle Lujan-Grisham signed several bills into law regarding New Mexico State taxes. Addressing taxes including individual income, corporate income, trust income, sales and use, and excise tax changes. The measures included in the newly signed laws are:
