Summary

County opts in, and every local taxing unit follows.

This bill lets a county commissioners court choose to exempt from property taxes the added value that a rainwater harvesting or graywater system brings to a person's property. If a county adopts the exemption, it applies to every local taxing unit that taxes that property, not just the county. The bill takes effect January 1, 2026, but only if voters approve a matching constitutional amendment, and it applies only to tax years starting on or after that date.

Passage of the bill would authorize the commissioners court of a county to adopt an exemption from ad valorem taxation of the portion of the appraised value of a person's property that is attributable to the installation in or on the property of a rainwater harvesting or graywater system that would apply to all taxing units that tax the property. As a result, taxable property values could be reduced and the related costs to the Foundation School Fund could be increased through the operation of the school finance formulas.

A BILL TO BE ENTITLED

AN ACT

relating to the authority of a county commissioners court to adopt

an exemption from ad valorem taxation by each taxing unit that taxes

the property of the portion of the appraised value of a person's

property that is attributable to the installation in or on the

property of certain water conservation systems.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:

SECTION 1. Subchapter B, Chapter 11, Tax Code, is amended by

adding Section 11.325 to read as follows:

Sec. 11.325. WATER CONSERVATION SYSTEMS. (a) In this

section, "graywater" has the meaning assigned by Section 341.039,

Health and Safety Code.

(b) The commissioners court of a county by order may adopt

an exemption from taxation of the portion of the appraised value of

a person's property that is attributable to the installation in or

on the property of a rainwater harvesting or graywater system. An

exemption adopted by a commissioners court under this section

applies to the taxation of property by each taxing unit that taxes

the property.

SECTION 2. This Act applies only to ad valorem taxes imposed

for a tax year beginning on or after the effective date of this Act.

SECTION 3. This Act takes effect January 1, 2026, but only

court of a county to exempt from ad valorem taxation by each

political subdivision that taxes the property the portion of the

assessed value of a person's property that is attributable to the

installation in or on the property of a rainwater harvesting or

graywater system is approved by the voters. If that amendment is

not approved by the voters, this Act has no effect.
