Property tax ballot measures must be labeled only numerically or alphabetically, not descriptively, and require simple majority approval; beginning January 1, 2027, ballot language must include detailed information such as current vs. proposed tax rates, percentage changes, duration, purpose, and estimated impact on residential, commercial, agricultural, and motor vehicle property per $100,000 of appraised valuation

Assessed property value increases exceeding 15% from the previous assessment (excluding new construction) must be spread evenly across successive two-year reassessment cycles, with county assessors and collectors applying credits to prevent tax liability increases greater than 15% in any reassessment period
