Tax season is just around the corner! Arizona Taxpayers can contribute up to $200.00 per single taxpayer or $400.00 per household filing jointly to the Arizona school or schools of their choice and receive a dollar-for-dollar reduction in their tax liability on their Arizona state tax return. GCOA can in turn use these contributions to fund outdoor field work, specials classes, and other critical programs. You can claim the tax credit when filing your Arizona State Tax Return. Those filing a paper return should use Form 322. For details, visit Arizona Department of Revenue’s website.
