Property taxes are ad valorem taxes — meaning "according to value." They are a primary source of revenue for local governments and schools.
How property taxes are calculated:
Assessed Value × Mill Rate = Annual Tax
Mill rate: Tax per $1,000 of assessed value. 1 mill = $0.001 (one-tenth of one cent).
Example: Assessed value $200,000 × mill rate 20 (2%) = $4,000/year
Assessed value vs. market value:
Assessed value is set by the tax assessor — often a percentage of market value (the assessment ratio).
Example: 80% assessment ratio on $300,000 home = $240,000 assessed value
Exemptions that reduce taxable value:
Homestead exemption — reduces assessed value for primary residence
Senior citizen exemption
Veterans exemption
Disability exemption
Tax lien: Unpaid property taxes become a lien on the property — priority lien over almost all others including mortgage liens.
