How property tax is calculated
Your local assessor values the property, some places tax only a percentage of that value (the assessment ratio), exemptions come off, and the combined rate of your county, city and school district is applied.
Example: a $300,000 home assessed at 100% with a 1.2% rate pays $3,600 a year, or $300 a month through escrow. The same rate written in mills is 12.
Where to find your numbers
- Your assessment notice or county assessor's website shows the assessed value and exemptions.
- Your tax bill lists each taxing district's rate; add them for the total.
- Homestead exemptions lower the taxable value of your main home in many states; some states also offer senior, veteran or disability exemptions. Apply through the assessor.
- If the assessed value looks too high compared with similar homes, you can appeal, usually within a short window after the notice.

Frequently asked questions
How do I calculate property tax?
Multiply the taxable assessed value by the tax rate. A $250,000 taxable value at 1.5% is $3,750 a year.
What is a mill rate?
Tax per $1,000 of assessed value. 20 mills means $20 per $1,000, the same as 2%.
Is property tax included in my mortgage payment?
Usually, if your lender uses an escrow account: it collects one-twelfth of the yearly tax each month and pays the bill for you.
