Property Tax Bills Across Grimes County, Texas
Property tax bills in Grimes County are based on the assessed value of a home, not its market price alone. Local taxing units apply their tax rates to that assessed value, and the total bill is the result of those combined rates. Factors such as the home’s value, exemptions, and the taxing jurisdictions that serve the property all affect what a homeowner pays.
With a median home price of $65,510, bills can vary widely across the county. The 25th percentile tax bill is $250, while the 75th percentile is $2,873 and the 90th percentile reaches $5,450. That spread shows how much location and assessment differences can change the final amount.
Homeowners in higher-tax areas may see much larger bills than those in lower-tax areas, even when home values are similar. For example, the highest median tax bill is $7,805 in Montgomery, while the lowest is $417 in Plantersville.
