How Property Tax Is Calculated

Local governments fund schools, roads, police, and fire departments largely through property taxes. Your bill is based on your home's assessed value (which may differ from its market value) multiplied by your local tax rate, often expressed as a "mill rate" — the dollars owed per $1,000 of assessed value.

Assessed Value = Market Value × Assessment Ratio
Taxable Value = Assessed Value − Exemptions
Annual Property Tax = Taxable Value × Tax Rate

Understanding Assessment Ratios & Exemptions

Some states or counties assess homes at 100% of market value, while others use a lower ratio (for example 50% or 60%) as a matter of local policy — always check your county assessor's site for your area's exact ratio. Homestead exemptions, senior exemptions, veteran exemptions, and other credits reduce the taxable value before the rate is applied, which is why two identically priced homes can have very different tax bills.

❓ Frequently Asked Questions

What's the difference between assessed value and market value?
Market value is what your home would likely sell for today. Assessed value is the value your local government uses for tax purposes, which may equal market value or be a set percentage of it (the assessment ratio), depending on your state.
What is a mill rate?
A mill rate is the tax owed per $1,000 of assessed value. A mill rate of 11 means $11 of tax per $1,000, which equals a 1.1% tax rate — enter it here as a percentage by dividing the mill rate by 10.
How often does assessed value change?
This varies widely by jurisdiction — some counties reassess annually, others every few years, and some only when a property sells or is significantly renovated.
Are property taxes included in my mortgage payment?
Often yes. Many lenders collect 1/12th of your estimated annual property tax (and homeowners insurance) each month into an escrow account and pay the tax bill on your behalf.
Can I appeal my property tax assessment?
Yes, most jurisdictions allow homeowners to formally appeal an assessment they believe is too high, typically by providing comparable sales data or an independent appraisal.
