McMullen County holds the distinction of having the lowest effective property tax rate in Texas at 0.41%, according to Census data — and it’s not hard to see why. With fewer than 700 residents in 1,100 square miles of South Texas brush country, Tilden serves as the county seat for a community built around cattle ranching, hunting leases, and occasional oil and gas activity. The county’s low rate reflects minimal government expenditure in a place where services are limited by design.
At 0.41%, McMullen County’s effective rate is among the lowest in the United States, let alone Texas. But for ranch and hunting lease operations whose values have risen with South Texas outdoor recreation demand, even a very low rate on an inflating base can produce unnecessary bills. Few protests are filed in counties this small. Your deadline is May 15, 2026.

“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”
— Section 13, Declaration of Rights, Republic of Texas, 1836
McMullen County has the lowest property tax rate in Texas — a testament to a community that has kept government small and property rights paramount. The founders of the Republic wrote exactly that commitment into the Declaration of Rights: no property shall be taken without consent and just compensation. Even at 0.41%, an inaccurate appraisal is an inaccurate appraisal. Look up your value. File your protest. The lowest rate in Texas doesn’t mean every valuation is fair.
