Official Property Tax Resources
Every resource below is either an official government source — statute, department of revenue, county assessor, appeal board — or an AssessCheck guide built from those sources. Nothing here is a third-party summary: where an official source exists for information, we link to it, including rather than to our own pages.

What is not here, deliberately
County-level links appear only where the site has verified them (for example Harris and Dallas in Texas, Franklin in Ohio, Fairfax in Virginia). For other counties, start from the state-level directory above — each state’s department or association directory is the official route to your county office.
