How To Use
Find out if you're overpaying property taxes and whether an appeal makes sense
🚀 Getting Started
1
Enter Your Assessment
Find your assessed value on your property tax bill or county assessor website. Enter it along with your local tax rate (usually 0.5%-3%).
2
Add Comparable Homes
Find 3 similar homes nearby (same size, beds, baths, age). Use Zillow, Redfin, or your county assessor's database for recent sale prices.
3
See If You're Overpaying
The calculator compares your assessment to the average of your comps. If yours is significantly higher, you have a case for appeal.
4
Calculate Appeal ROI
See how much you'd save per year, over 5 years, and whether the filing fee + time investment is worth the potential savings.
📊 Terms Made Simple
Assessed Value: What your county says your home is worth for tax purposes. This is NOT necessarily the market value — it can be lower or higher depending on when you were last assessed.
Mill Rate / Tax Rate: The amount of tax per dollar of assessed value. A rate of 1.3% means you pay $1.30 for every $100 of assessed value. This varies widely by location.
Comparable Properties (Comps): Similar homes near yours — same size, bedrooms, bathrooms, age, and condition. Their sale prices or assessed values are the strongest evidence in a tax appeal.
Tax Appeal: A formal request to your county to reassess your property value. If successful, your assessed value drops and your annual tax bill decreases. Most appeals are free or have a small filing fee.
