Frequently Asked Questions - 2020 Individual Income Tax Changes

Arizona itemized deductions are the same as the federal itemized deductions except:

  • All qualified medical expenses are allowed.
  • Any charitable donations claimed on the federal return for which an Arizona credit is claimed, must be removed from the Arizona itemized deductions.
  • State income taxes deducted on the federal return that includes an amount for charitable donations must be reduced by the amount of the charitable donations claimed as an Arizona tax credit.
  • Arizona will allow a deduction for mortgage interest not allowed on the federal return due to claiming a federal mortgage credit.

The 2020 standard deduction amounts are $12,400 for single, $18,650 for head of household or $24,800 for married filing joint.  In addition, the standard deduction may be increased by 25 percent of the charitable deductions the taxpayer would have been able to claim if the taxpayer had claimed itemized deductions.   The increased amount for charitable deductions may not be claimed on Arizona Forms 140A or 140EZ.

The dependent exemptions are no longer available.  However, the exemption is replaced by a dependent tax credit.  The dependent credit is $100 for each dependent under the age of 17 and $25 for each dependent that is age 17 or over.  The dependent must meet the federal dependent requirements.  The credit is phased out for those taxpayers with federal adjusted gross income over $400,000 for married filing joint and over $200,000 for all others.

Yes, the exemptions for the taxpayer or the taxpayer’s spouse being blind or over 65 remain unchanged.

The following exemptions, previously allowed on the dependent line of the return are now allowed on the “other exemptions” line of the return:

  • There is $2,300 for each person 65 years of age or older regardless of the person’s relationship with the taxpayer:
    • If the taxpayer pays for more than one-fourth of the total cost of maintaining that person in a nursing care institution, residential care institution or assisted living facility if such payments exceed $800 in the taxable year.
    • If the taxpayer otherwise makes payments exceeding $800 in the taxable year for home health care or other types of medical care.
  • There is $2,300 for each birth for which a certificate of birth resulting in stillbirth was issued if the child would have otherwise become a member of the taxpayer’s household. Allowed in the year in which the stillbirth occurred.

The exemption on the “other exemptions” line is instead of any other exemption or credit for the same individual.  

The starting point for the Arizona individual income tax return is the federal adjusted gross income (FAGI) determined on the federal return.  This number is then adjusted for specific Arizona additions, subtractions, deductions and exemptions to determine Arizona taxable income.  The deduction taken on the federal return for qualified business income (QBI) is taken after the determination of FAGI on the federal return; therefore, the deduction is not part of Arizona’s starting point.  In addition, Arizona does not have an Arizona specific adjustment to allow the QBI deduction.  Therefore, QBI may not be deducted on the Arizona return.
