How US Property Taxes Work in 2026
Real estate property taxes are local municipal taxes used to fund public school districts, police, fire departments, roads, and libraries. Your tax bill equals your Taxable Assessed Value (Assessed Value minus Homestead Exemptions) multiplied by your local Millage Tax Rate. Effective rates range from 0.28% in Hawaii to 2.49% in New Jersey.

Understanding Millage Rates & The Property Tax Formula
Local tax jurisdictions (school districts, county commissioners, township boards, and water authorities) express taxes in mills. One mill equals one-thousandth of a dollar ($0.001), or $1 per $1,000 of assessed property valuation.
📐 The Standard Property Tax Calculation:
Annual Property Tax = [(Fair Market Value × Assessment Ratio) - Homestead Exemptions] × (Total Millage Rate / 1,000)
How to Appeal an Overvalued Property Tax Assessment
County tax assessments frequently lag market downturns or rely on inaccurate square footage data. If your assessed value is higher than recent comparable sales:
- Request Property Record Card: Obtain your official property card from the county appraisal district and inspect it for incorrect bathroom counts, basement square footage, or condition ratings.
- Gather 3 to 5 Recent Comps: Find comparable homes in your immediate neighborhood sold within the last 6 months at a lower price per square foot.
- File Formal Appeal Before Deadline: Submit your appeal to the county Board of Equalization / Assessment Appeals during the annual protest window (typically April–May).
Frequently Asked Questions (FAQ)
How is property tax calculated from market value?
Property tax is calculated by multiplying your property's taxable assessed value (Fair Market Value × Assessment Ratio minus Exemptions) by the local millage tax rate: Annual Property Tax = (Taxable Assessed Value × Millage Rate) / 1,000.
What is a millage rate in property taxes?
A mill equals one-tenth of one cent ($0.001), or $1 of property tax per $1,000 of assessed value. A millage rate of 25 mills means you owe $25 in taxes for every $1,000 of taxable assessed valuation (2.50%).
Which US states have the highest and lowest property taxes in 2026?
New Jersey has the highest effective rate at 2.49%, followed by Illinois (2.27%) and Connecticut (2.15%). Hawaii has the lowest effective property tax rate at 0.28%, followed by Alabama (0.41%) and Colorado (0.51%).
What is a Homestead Exemption and how much does it save?
A Homestead Exemption reduces the taxable assessed value of your primary residence. For example, Texas provides a $100,000 school district homestead exemption, saving homeowners $1,200 to $1,500+ annually.
What is the difference between market value and assessed value?
Market value is the price a buyer would pay for your home on the open market. Assessed value is the valuation assigned by the county tax assessor for tax calculations.
How does property tax affect my monthly mortgage escrow payment?
Lenders divide your annual property tax bill by 12 and collect it monthly alongside your mortgage principal and interest payment, holding the funds in escrow to pay the county on the statutory due date.
Can you appeal your county property tax assessment?
Yes. If your county overvalued your property relative to neighborhood comps, you can file an appeal with your county Board of Assessment Appeals during the annual protest window.
Are real estate property taxes deductible on federal income taxes (SALT Cap)?
Yes, property taxes are deductible on Schedule A if you itemize, subject to the $10,000 statutory State and Local Tax (SALT) deduction cap for combined state income and property taxes.
