Estimate your annual property tax bill from your home's market value, the local tax rate (often called a mill rate or effective rate), and your jurisdiction's assessment ratio.
How it works
- Input the current market value of your home.
- Enter the effective property tax rate (mill rate) for your county.
- Adjust the assessment ratio (if less than 100%) to calculate your exact tax bill.
Frequently asked questions
Where do I find the tax rate?
Your county or municipality assessor's website lists the mill rate. One mill = $1 per $1,000 of assessed value, or 0.1%. Typical US rates run 0.5–2.5%.
Can I appeal my assessment?
Yes — most jurisdictions have an appeals process. If your assessment exceeds comparable home sales, an appeal can reduce your bill.
Is property tax deductible?
In the US, up to $10,000 of state and local taxes (SALT) including property tax can be deducted on federal returns if you itemize.
How do I find the assessment ratio for my area?
Your county or municipal assessor's website publishes the assessment ratio (sometimes called the equalization rate). It may be 100% (assessed at full market value) or a lower percentage like 85% or 70%.
