Assessor Petersen Adds Medical Marijuana Businesses to 2017 Personal Property Roll

Contact: Ryan Boyd
Tel: (602) 372-9295

PHOENIX — Maricopa County Assessor Paul Petersen will mail out notices of value and applicable penalties to business personal property owners, including for the first time medical marijuana businesses, on August 25, 2017.

"Keeping the property tax roll as fair and accurate as possible is my number one priority," said Petersen, "Property taxes support critical services for Maricopa County residents, including education, where 54% of dollars go to school districts and another 11% go to community colleges."

Medical marijuana was legalized in Arizona after the narrow passage of Proposition 203 in 2010. Proposition 203 did not exempt medical marijuana businesses from property taxes and they are not included in a long list of exemptions kept in statute.

On January 6, 2017, the Assessor's Office mailed an Arizona Business Property Statement Form to business personal property owners across Maricopa County. According to A.R.S. 4215053, all owners of personal property must file a Business Property Statement annually by April 1st whether or not they received a form from the Assessor. Further, pursuant to A.R.S. 42-15055, failure to report shall result in a penalty of an additional 10 percent based of the estimated value of the property.

Of 109 dispensary, cultivation, duel locations and certification businesses located in Maricopa County, only 11 reported their business personal property. Like any other business, these medical marijuana facilities that failed to report their business personal property will be assessed a 10 percent penalty.

"If Walgreens, CVS, hospital pharmacies, and other medical facilities can report their business personal property timely and accurately, why can't medical marijuana businesses do the same?" said Petersen. "If medical marijuana business owners want to be treated the same as a legitimate business, then they must also act like a legitimate business, which includes paying their property taxes on their business personal property", Petersen added.

Assessor Petersen Releases Tax Year 2018 Valuation Notices

Phoenix --- On February 17, 2017, the Maricopa County Assessor's Office will send out approximately 1.6 million valuation notices for tax year 2018 to all property owners in Maricopa County. Positive growth continues with a five year upward trend in single-family residential properties, with an increase in the median Full Cash Value (FCV), of 7.98 percent. This appreciation brings the median single-family FCV up to approximately $197,600 in Maricopa County.

Single-family residential properties saw the lowest amount of growth out of all property classes except for commercial. This is the fourth year of growth in the commercial area. Median values for commercial grew 5.78 percent, bringing 2017 median value of $480,100 up to $507,850 in 2018. Median values for vacant land increased 9.06 percent, with a median value of $33,700 compared to $30,900 from last year. Apartments had the largest increase out of all classes, with a median value of $187,200, up 13.59 percent from $164,800 in 2017. Median values for manufactured housing grew 10.6 percent from $60,400 in 2017 to $66,800 in 2018.

"All property types are seeing positive growth which is consistent with what we have seen in the past few years," said Petersen "The housing market in Maricopa County has now nearly recovered from the recession that occurred from 2008-2010."

To illustrate this, the high point in the median FCV for a single family residential property was approximately $229,500 in tax year 2008. The low point occurred in tax year 2013 when the median single family FCV was $109,600.

The Maricopa County Assessor's Office strives to serve the taxpayers of the county with accuracy, equity, transparency, and efficiency. The Maricopa County Assessor's Office is, in fact, run as one of the lowest cost and most efficient assessment offices in the country. For example, through the office's legal class verification program, the office has saved over $38 million for the State of Arizona in state aid credit to education funding during the past three years.

This year, the Maricopa County Assessor's Office is launching a new efficiency measure through its e-notice program. The e-notice program will allow property owners to opt-in to receive future notices of value online with an authorization code attached to their 2018 notice of value. This will save the county and property owner's time and money required to mail notices and replies while providing accurate, quality services to the public.
