Supported counties

Property tax appeal help built county by county

Every live county uses the same HomeTaxChallenge lookup and comparable-sales core with local public-data adapters, filing rules, forms, deadlines, and copy.

We only call a county supported when the full workflow is ready; Lite counties are grouped separately and offer parcel lookup, filing guidance and a preliminary estimate from the assessed value. A county name on this page links to its dedicated calculator and local information pages — homeowners are not sent through a generic calculator.

Full support (Tier 2) (43)

Comparable-sales screening, deadline tracker and county appeal guide (information only).

Lite (preliminary estimate) (107)

Parcel lookup, filing guidance and a preliminary estimate from the assessed value only (no comparable sales yet).
