How does the property tax savings calculator estimate my taxes?

It takes your assessed value and your estimate of market value, applies your state’s statutory assessment ratio to find the county’s implied market valuation, and if that implied value exceeds your home’s worth, estimates savings using an average regional millage rate.

What is an assessment ratio?

The percentage of market value that is taxable. Tennessee taxes at 25%, Georgia at 40%. A $400,000 home is assessed at $100,000 in TN or $160,000 in GA. The calculator handles all 50 states automatically.

Can my property taxes go up if I file an appeal?

In almost all US jurisdictions the review board can only lower or maintain your assessment during an owner-initiated appeal, not raise it.

Understanding the Math of Assessment Ratios

Many homeowners get confused when looking at their annual property assessment notice. If you live in a state with a low fractional assessment ratio, the assessed value shown on your tax document is not what the county thinks your home is worth on the market.

Example calculation:
In Tennessee, the residential assessment ratio is 25%. If your county tax assessment shows an assessed value of $100,000, the county's implied market value of your home is:
$100,000 ÷ 0.25 = $400,000If your property would only sell for $350,000 today, the county has overassessed your house by $50,000.

By filing a formal property tax appeal, you challenge this discrepancy. Our tool converts fractional assessment values into real-world market values so you can easily compare your home with neighboring comps.

What to Do If Your Assessment is Too High

1. Verify Your County Property Card

Check for factual errors, such as the county listing incorrect square footage, land acreage, or claiming you have structural improvements that do not exist.

2. Pull Local Sales Comparables (Comps)

Find 3 to 5 properties of similar build, size, and year in your immediate neighborhood that sold for less than your county assessment value in the past 12 months.

3. File Your Protest Before the Cutoff

Submit the official county appeal form (e.g. Form 50-132 in Texas) along with your comps report before the statutory state deadline (typically May 15).
