About TaxLash

TaxLash is property tax protest software built for Texas: for the firms that file protests, and for the property owners they represent.

Why we built it

Protest season is short and the deadlines are hard. Firms were running it on spreadsheets, paper forms and email. TaxLash puts clients, parcels, filings, deadlines, hearings, invoices and agents in one place, so a firm can protest more properties with less paperwork.

Made for Texas

TaxLash follows the Texas protest calendar and forms, and holds appraisal data for all 254 Texas counties, refreshed every month from the public appraisal district records.

For firms and for owners

Firms get their own TaxLash with their own logo, users and clients. Their clients get an Owner Center to sign agreements, follow their protests and pay invoices, in their own language.

Your data stays yours

Each firm's clients, parcels and invoices are kept apart from every other firm's. The public pages never show an owner's name.
