Property Tax (real estate and personal property)

Property taxes are established and collected by individual counties and taxing districts, not by the state. The collected funds are used to finance local services, such as roads, schools and libraries. Two types of property tax are collected.

Personal property tax is assessed on the value of depreciable assets owned by a business, including machinery, equipment, office equipment, software and more. The tax is paid annually or semi-annually in December and June to your local county assessor. The first $100,000 of a business’s personal property is exempt from taxation.

Real estate property tax is collected on the assessed value of real estate (real property) owned by a business or an individual. Real estate taxes are paid annually or semi-annually in December and June to your local county assessor.

Important: Personal property tax is not in any way related to income tax. If you own a business, you may owe property tax. The tax must be paid even if your business has no income or does not owe income tax. Failure to pay property tax can result in a lien being filed against business real estate and/or equipment.
