How It Works: Assessed Values, Millage Rates & Exemptions
Real estate property taxes are ad valorem taxes levied by local government authorities (counties, cities, school districts) to fund public services like schools, police, and infrastructure. Local tax assessors determine a home's **assessed value** (which may equal 100% of fair market value or a fractional assessment ratio). Subtracting state **homestead exemptions** yields the **taxable value**. Tax rates are expressed either as a **percentage (%)** or a **millage rate** (where 1 mill equals $1 in tax per $1,000 of assessed value).
Formula Explanation
Assessed value ($Val_{assessed}$), taxable value ($Val_{taxable}$), annual property tax bill ($Tax_{annual}$), and effective tax rate ($Rate_{eff}$) are computed as follows:
Step-by-Step Worked Example
Here is a detailed 5-step breakdown for a homeowner with a $350,000 market value home in a county with a 100% assessment ratio, a 1.25% tax rate (12.5 mills), and a $25,000 homestead exemption:
- Step 1 (Calculate Gross Assessed Value): $\$350,000 \times 100\% = \mathbf{\$350,000.00}$.
- Step 2 (Apply Homestead Exemption): $\$350,000 - \$25,000 \text{ exemption} = \mathbf{\$325,000.00 \text{ Taxable Value}}$.
- Step 3 (Calculate Annual Property Tax Bill): $\$325,000 \times 1.25\% = \mathbf{\$4,062.50 / year}$.
- Step 4 (Calculate Monthly Escrow Requirement): $\$4,062.50 \div 12 \text{ months} = \mathbf{\$338.54 / month}$.
- Step 5 (Compute Effective Tax Rate): Effective rate $= (\$4,062.50 \div \$350,000) \times 100 = \mathbf{1.16\%}$ (homestead exemption saves $\$312.50$ per year)!

Frequently Asked Questions (FAQ)
How are property taxes calculated on a home?
Property taxes are calculated by multiplying your home's taxable assessed value (after exemptions) by the local municipal and county tax rate.
What is a millage rate or mill rate in property taxes?
A mill rate is the tax amount per $1,000 of assessed value. 1 mill equals $1 per $1,000 (or 0.1%). A 15 mill rate equals a 1.5% tax rate.
What is the difference between market value and assessed value?
Market value is the estimated sale price of the home. Assessed value is the dollar value assigned by local government tax assessors to calculate property taxes.
What is a Homestead Exemption?
A Homestead Exemption is a state or county provision that reduces the taxable assessed value of your primary residence, lowering your annual property tax bill.
What US states have the highest property tax rates?
New Jersey (2.49%), Illinois (2.23%), Connecticut (2.15%), New Hampshire (2.09%), and Texas (1.90%) have the highest effective property tax rates in the nation.
What US states have the lowest property tax rates?
Hawaii (0.32%), Alabama (0.41%), Colorado (0.51%), Nevada (0.55%), and South Carolina (0.56%) feature the lowest effective property tax rates.
Can I appeal my property tax assessment if it is too high?
Yes. Property owners can file a formal property tax appeal with their county board of assessment if they believe their home's assessed value exceeds fair market value.
How does buying a home reset property taxes?
In many states (like California under Prop 13 or Florida), buying a home triggers a tax reassessment based on the new purchase price, increasing annual taxes.
Are property taxes tax-deductible on federal tax returns?
Under current IRS SALT (State and Local Tax) deduction rules, homeowners itemizing deductions can deduct up to $10,000 in combined state property and income taxes.
What happens if a property tax escrow shortage occurs?
If local property tax rates rise, your mortgage servicer will experience an escrow shortage and will increase your monthly payment to cover the deficit.
