County Assessor, Kathleen Arviso
The major functions of the Assessor’s Office are to
discover, locate and value all residential and non-residential property
within McKinley County.
Arviso and her staff of four appraisers and a mapper locate properties through
surveys, mortgages, and deed transactions, and then go into the field to
inspect new constructions and place a value on each dwelling or property.
The taxable value of the property
typically is one third of the full property value, so property owners
pay taxes on only one third of the actual value of their property minus
any allowable exemptions, such as head-of-household or veteran's.
The Assessor establishes these taxable property valuations and
provides that information to the New Mexico Department of Finance and
The County Treasurer then uses a complex rate
schedule set by the New Mexico Department of Finance and Administration (DFA)
to determine the amount of tax owned by the property owner and then levies
and collects property taxes to help fund the operations of McKinley County
and cover debt service on bonds that have been passed.
important that property owners review the valuation figures on the Notice of
Value (NOV), because this is the last step in the review process. The value on
the notice is what will be used to calculate the taxes you will pay after your
local government agencies and school districts set their budgets and the tax
rates are adopted. An exception to this is agricultural land, which s assessed
and set by the State’s Property Tax Division.
The Assessor’s Office also provides information on
projected property tax income for the McKinley County budget as well as
helping to establish the overall value of the county with the DFA.
The total valuation of McKinley County property is $694,496,903.
The picture is complicated by the fact that 80 percent of the land
in the county is Indian reservation land or other non-taxable federal
land. Only businesses on reservation land that are owned by
non-tribal members are taxable and only 20% of the total land in the
county actually is taxable.
Arviso and her staff maintain computerized tax roles
of about 16,227 property owner accounts with legal descriptions and values
of each piece of property. The
Assessor also works with the County Clerk to keep track of all deed
transfers when property is bought and sold.
