According to Realtor.com's new property tax report, more than 40% of properties in the U.S. may be overassessed

AUSTIN, Texas , April 29, 2025 /PRNewswire/ -- Many homeowners could be overpaying their property taxes and not even know it. In fact, 40.5% of properties in the U.S. may be overassessed, according to a new Realtor.com^® Property Tax Report. And, today, for the first time on a major real estate platform, homeowners can not only uncover potential savings, they can get the evidence they need to challenge over-assessed property values through a new tax protesting resource on Realtor.com^®.

"Most homeowners don't realize they can protest their property taxes, and even fewer know how to do it," said David Masters, Sr. Director of Product at Realtor.com^®. "We built this resource to simplify what has traditionally been a confusing and intimidating process. By integrating it into the My Home dashboard, we're giving homeowners a clear view into what they might be overpaying, equipping them with solid evidence, and making it easy to take action. Our goal is to help people feel more confident navigating the protest process, and potentially save money."

Millions Could Benefit from Protesting… Especially in These States
A Realtor.com^® analysis found that over 40% of U.S. homes are potentially overassessed to the point that the owner could save $100 or more by protesting. The median potential savings is $539 per year, equivalent to more than 15% of the average property tax bill. Some states offer especially high opportunities for tax relief.  Here are the five states with the largest share of properties for which protesting may make financial sense, and the estimated median savings if those homeowners filed a successful protest:

Top States with Highest Opportunity for Property Tax Relief

In states like California, long-standing caps on annual assessment increases have created significant variation between similar homes, which makes it more complicated to collect comparable properties because neighbors might be locked into an old assessment. This can inflate the number of properties that look like they are overassessed. Meanwhile, Texas and Illinois, with their relatively high effective tax rates, offer even small-assessment adjustments that result in major savings.

Built-In Support for Homeowners When They Need It Most
The tax protesting resource comes at a critical moment and is available to homeowners who claim their home in the My Home dashboard on Realtor.com^®. According to the Realtor.com^® Tax Protest Report, the median property tax bill in the U.S. climbed to $3,500 in 2024, a 2.8% increase from 2023. This uptick is largely due to rising home values, with median assessed values increasing by 2.0%, alongside changes in local tax rates.

Some states have seen far more dramatic spikes. Georgia led the nation with a staggering 15.6% increase in median property tax burden, despite assessed values rising by just 4.8%, indicating significant local rate hikes. Other high-growth states include:

However, some states saw decreases or no change to their median tax burden between 2023 and 2024 including Nebraska, Michigan, Kentucky, Washington and Tennessee, showing that these states actually experienced healthy growth in home values at the same time that property taxes fell significantly.

Methodology
For the year over year analysis, tax records from 2023 and 2024 are collected from properties only where both years are available. Data is from the Realtor.com tax assessment database. Year over year changes are calculated at the property level and aggregated by state from there. Vermont, Indiana, Illinois, Arkansas, Washington DC, North Dakota, and South Dakota were excluded from the year over year analysis due to missing data. Potential savings from property tax protesting are calculated by comparing the actual tax bill for a property for the most recent tax year against the product of that property's effective tax rate (actual tax bill divided by actual assessment value) and the property's hypothetical assessment value (market value multiplied by the average assessment-to-market value ratio for the property's county). Market values are determined as the median of the most recent valuations from several valuation vendors.
