What you'll need

Have the information needed for the lines that apply to you:

  • Your Arizona tax liability for line 1.
  • Your 2024 return if you are a C corporation or exempt organization. Line 2b asks for the tax shown on that return.
  • Taxable income for each applicable period if using Schedule A.
  • Amounts for tax credit recapture, nonrefundable credits, refundable credits, and any claim of right adjustment if completing Schedule A.
  • If using the adjusted seasonal installment method, taxable income for the specified periods in tax years beginning in 2022, 2023, 2024, and 2025.

Several lines refer to separate instructions, which were not provided with this text.

Common mistakes

  • Missing the PTE election checkbox: The form tells partnerships and S corporations making the PTE election to check the box and read the instructions before proceeding.
  • Using the seasonal method without qualifying: The printed caution says to use this method only if the base period percentage of any six consecutive months is at least 70%. The method is not available to partnerships or S corporations making the PTE election.
  • Overlooking the large-corporation note: On Schedule A, line 48, large corporations are directed to the instructions for line 4 to determine the amount to enter.
