Should Texas require the comptroller to annually allocate the first $1 billion in net sales tax revenue after revenue exceeds $46.5 billion to the Texas Water Fund?

Proposition 4 would amend the Texas Constitution to authorize the Texas State Legislature to require the comptroller to annually allocate the first $1 billion in net sales tax revenue after revenue exceeds $46.5 billion to the Texas Water Fund. The comptroller's authority to allocate the first $1 billion would expire on August 31, 2047. The allocation would be administered in a separate account in the fund, and the amendment would prohibit the use of the funds unless an appropriation law is passed. Proponents, such as the American Council of Engineering Companies of Texas, argue the…   state will need to invest at least $154 billion in the coming decades toward expanding our water supply portfolio and fixing aging, deteriorating systems. Opponents argue it crowds out private-sector solutions, reduces future tax relief opportunities, and limits legislative accountability for long-term fiscal commitments.
