43-1041.
Optional standard deduction
A. A taxpayer may elect to take a standard deduction as follows:
1. In the case of a single person or a married person filing separately,  the standard deduction is $12, 200,  subject to subsection H of this section.
2. In the case of a single person who is a head of a household,  the standard deduction is $18, 350,  subject to subsection H of this section.
3. In the case of a married couple filing a joint return,  the standard deduction is $24, 400,  subject to subsection H of this section.
B. The standard deduction provided for in subsection A of this section is in lieu of all itemized deductions allowed by section 43-1042,  which are to be subtracted from Arizona adjusted gross income in computing taxable income.
C. The standard deduction is allowed if the taxpayer so elects. The election is made by the taxpayer claiming on the tax return the amount provided for in this section in lieu of the itemized deductions allowed under section 43-1042. Electing to file a short form return or a simplified return that does not allow itemized deductions to be claimed is considered to be an election to claim the standard deduction.
D. In the case of a husband and wife,  the standard deduction provided for in subsection A of this section is not allowed to either if the taxable income of one of the spouses is determined without regard to the standard deduction.
E. The standard deduction provided for by subsection A of this section is not allowed in the case of a taxable year of less than twelve months on account of a change in the accounting period.
F. Except as provided in subsection G of this section,  a change of an election to take,  or not to take,  the standard deduction for any taxable year may be made after the filing of the return for that year.
G. A taxpayer is not allowed to change an election to take,  or not to take,  the standard deduction if:
1. The spouse of the taxpayer filed a separate return for any taxable year corresponding,  for the purposes of subsection D of this section,  to the taxable year of the taxpayer unless both of the following apply:
(a) The spouse makes a change of election with respect to the standard deduction for the taxable year covered in the separate return consistent with the change of election sought by the taxpayer.
(b) The taxpayer and spouse consent in writing to the assessment,  within such a period as may be agreed on with the department,  of any deficiency,  to the extent attributable to the change of election,  even though at the time of filing the consent the assessment of the deficiency would otherwise be prevented by the operation of any law or rule of law.
2. The tax liability of the taxpayer or the taxpayer's spouse for the taxable year has been compromised.
H. For each taxable year beginning from and after December 31,  2019,  the department shall adjust the dollar amounts prescribed by subsection A,  paragraphs 1,  2 and 3 of this section for inflation in the same manner in which the federal basic standard deduction is adjusted for inflation pursuant to section 63 of the internal revenue code.
I. For taxable years beginning from and after December 31,  2018,  the standard deduction allowed under subsection A of this section shall be increased by the amount equal to twenty-five percent of the total amount of a taxpayer's charitable deductions that would have been allowed if the taxpayer elected to claim itemized deductions under section 43-1042 rather than elect the standard deduction. For taxable years beginning from and after December 31,  2021,  the department shall adjust the percentage prescribed in this subsection according to the average annual change in the metropolitan Phoenix consumer price index published by the United States department of labor,  bureau of labor statistics,  except that the adjusted percentage may not exceed one hundred percent. The revised percentage shall be raised to the nearest whole percent and may not be revised below the amounts prescribed in the prior taxable year.
