The Department may require or allow averaging of monthly values if that method is required to properly reflect the average value of a taxpayer's property for the tax period. The Department shall not require the averaging of monthly values if that method has a de minimis effect on a taxpayer's Arizona tax liability for the tax period.
Example: The monthly value of the taxpayer's property is as follows:
January | $2,000 | July | $15,000 |
February | $2,000 | August | $17,000 |
March | $3,000 | September | $23,000 |
April | $3,500 | October | $25,000 |
May | $4,500 | November | $13,000 |
June | $10,000 | December | $2,000 |
Subtotal | $25,000 | Subtotal | $95,000 |
Total | $120,000 |
The average monthly value of the taxpayer's property includable in the property factor for the income year is $10,000 (120,000 divided by 12).
