The tax-cut package includes a proposed property tax break worth about $125 a year for the average Texas homeowner. The increase in the homestead exemption on school property taxes, though, still must be approved by voters.

Correct. The tax cuts and related stuff goes through the Legislature. The homestead exemption, however, is Constitutional, not general code, and therefore requires a Constitutional amendment. Not just a simple TX Legislature/Gov signature.
