Property taxes can feel like a mysterious bill that just shows up in your mailbox each year. But once you understand how property taxes are calculated, the whole process becomes a lot less intimidating. Let’s break it down in plain English so you can spot mistakes, budget better, and maybe even lower your bill.
Step 1: The Assessed Value
Your local tax assessor estimates what your home is worth. This isn’t always the same as your market value. For example, your home might sell for $300,000, but your county could assess it at $250,000.

Step 2: The Tax Rate (Millage Rate)
Local governments apply a tax rate, often called a millage rate, which is the amount charged per $1,000 of assessed value. Example: A millage rate of 20 = $20 in taxes for every $1,000.
Step 3: Subtract Exemptions
Many states offer homestead exemptions, senior discounts, veteran credits, or agricultural reductions. These can significantly lower your taxable value.
A Quick Example
- Assessed Value: $250,000
- Homestead Exemption: $25,000
- Taxable Value: $225,000
- Local Rate: 20 mills ($20 per $1,000)
Annual Taxes: $225,000 ÷ 1,000 x $20 = $4,500
