The Property Tax Process: Step by Step
Property Assessment
County assessors determine the market value of all properties in their jurisdiction, typically every 1-3 years.
- Market value assessment using comparable sales
- Physical inspections for new construction or major changes
- Mass appraisal techniques for efficiency
- Appeals process for disputed assessments
Apply Exemptions
Eligible exemptions are applied to reduce the taxable value of the property.
- Homestead exemptions for primary residences
- Senior citizen and disability exemptions
- Veteran exemptions for service members
- Agricultural and conservation exemptions
Calculate Tax Rate
Local governments set tax rates (mill rates) based on their budget needs and total property values.
- School districts typically represent 50-60% of total rate
- County government services and infrastructure
- Municipal services like police and fire
- Special districts for water, parks, libraries
Calculate Tax Owed
Tax owed = (Assessed Value - Exemptions) × Tax Rate
- Taxable value is assessed value minus exemptions
- Tax rate is sum of all local government rates
- Some states have assessment ratios (tax only portion of value)
- Result is annual property tax bill
Bill & Collection
Tax bills are issued and collected according to local schedules, typically annually or semi-annually.
- Bills mailed to property owners or mortgage companies
- Payment schedules vary by jurisdiction
- Penalties and interest for late payments
- Delinquent taxes may result in tax liens or foreclosure
