What each county actually charges, how the homestead exemption applies, and what it works out to per month. Free, and no signup.
These are the counties whose rates we researched individually, with the school district portion separated out because that is the only part a Texas homestead exemption reduces. All 331 counties in both states are selectable in the mortgage calculator.
Typical combined rates for the 2025 tax year as a percent of market value. Your exact rate depends on your city and school district, so every page links straight to that county's appraisal district or assessor. For the rules behind the numbers, read the Texas and Oklahoma property tax playbooks.
