Ariz. Admin. Code § R15-2B-101
A. An employer shall determine its Arizona withholding payment schedule for each calendar quarter by calculating the average amount of Arizona income taxes withheld in the 4 preceding calendar quarters. The employer shall calculate this average at the beginning of each calendar quarter by adding the actual amount withheld in each of the 4 preceding calendar quarters and then dividing that sum by 4.
1. If the average amount of Arizona income taxes withheld in the 4 preceding calendar quarters does not exceed $1,500, the employer shall make its Arizona withholding payments on a quarterly basis.
Example:
An employer determines its Arizona withholding payment schedule for the 4th calendar quarter of 1999 as follows:
3rd quarter of 1999 withholding $1,100
2nd quarter of 1999 withholding $1,600
1st quarter of 1999 withholding $1,000
4th quarter of 1998 withholding $1,200
Total withholding $4,900
Divide by 4
Average withholding $1,225
The 4 quarter average of Arizona income taxes withheld does not exceed $1,500. Therefore, the employer shall make its Arizona withholding payments on a quarterly basis.
2. If the average amount of Arizona income taxes withheld in the 4 preceding calendar quarters exceeds $1,500, the employer shall make its Arizona withholding payments at the same time as the employer is required to make its federal withholding deposits.
Example:
An employer determines its Arizona withholding payment schedule for the 3rd calendar quarter of 1999 as follows:
2nd quarter of 1999 withholding $1,800
1st quarter of 1999 withholding $1,400
4th quarter of 1998 withholding $1,900
3rd quarter of 1998 withholding $1,300
Total withholding $6,400
Divide by 4
Average withholding $1,600
The 4 quarter average of Arizona income taxes withheld exceeds $1,500. Therefore, the employer shall make its Arizona withholding payments at the same time as its federal withholding deposits.
B. An employer that purchases an existing business shall determine its Arizona withholding payment schedule for each calendar quarter by calculating the average amount withheld in the 4 preceding calendar quarters as follows:
C. A newly formed business shall determine its Arizona withholding payment schedule as follows:
F. For calendar years beginning after December 31, 1997, an employer may make its Arizona withholding payments on an annual basis if all of the following conditions are met:
H. An employer that makes its Arizona withholding payments on an annual basis under subsection (F), may continue to make its Arizona withholding payments on an annual basis for the succeeding calendar year if both of the following conditions are met:
1. The average amount of Arizona income taxes withheld by the employer in the 4 preceding calendar quarters does not exceed $200.
Example 1:
An employer determines whether the average amount of Arizona income taxes withheld in the 4 preceding calendar quarters does not exceed $200 as follows:
4th quarter of 1999 withholding $200
3rd quarter of 1999 withholding $200
2nd quarter of 1999 withholding $250
1st quarter of 1999 withholding $150
Total withholding $800
Divide by 4
Average withholding $200
The average amount of Arizona income taxes withheld in the 4 preceding calendar quarters does not exceed $200. Therefore, the employer may make its Arizona withholding payments on an annual basis for the succeeding calendar year, if the employer also meets the condition stated in subsection (H)(2).
Example 2:
An employer determines whether the average amount of Arizona income taxes withheld in the 4 preceding calendar quarters does not exceed $200 as follows:
4th quarter of 1999 withholding $200
3rd quarter of 1999 withholding $400
2nd quarter of 1999 withholding $250
1st quarter of 1999 withholding $150
Total withholding $1,000
Divide by 4
Average withholding $250
The average amount of Arizona income taxes withheld in the 4 preceding calendar quarters exceeds $200. Therefore, the employer may not make its Arizona withholding payments on an annual basis for the succeeding calendar year.
I. If the employer does not meet the conditions prescribed by subsection (H):
J. An employer shall determine the applicable rate of withholding for each employee as follows:
1. If an employee whose annual compensation is less than $15,000 elects the minimum withholding rate, that rate shall apply until 1 of the following situations occurs:
