A Texas homestead exemption reduces your MUD tax only if your Municipal Utility District’s board has voted to adopt a local-option exemption. School districts are required by state law to grant one; MUDs are not. That said, filing for the homestead exemption is still worth doing even when your MUD hasn’t adopted one, because it locks in a 10% annual cap on your home’s appraised value, and every taxing entity on your bill, including the MUD, calculates its tax from that same value.
Why MUDs Aren’t Required to Offer One
A Municipal Utility District is a special-purpose entity that funds water, sewer, drainage, and sometimes road or park infrastructure by levying its own property tax on homes inside its boundaries.1Texas Commission on Environmental Quality. Water Districts It appears as a separate line on your annual tax statement.
Texas law splits homestead exemptions into two categories. School districts must exempt $100,000 of a home’s appraised value, an amount written into the Texas Constitution when voters approved Proposition 4 in 2023.2State of Texas. Texas Tax Code 11-13 – Residence Homestead MUDs, along with cities, counties, and other taxing units, may choose to adopt an exemption of up to 20% of appraised value, with a $5,000 floor if 20% works out to less than that.3State of Texas. Texas Tax Code Chapter 11 – Taxable Property and Exemptions The board has to adopt it before July 1 of the tax year for it to apply that year.
So your neighbor one MUD over might see an exemption on that line while you see none. It’s a board-by-board decision.
The 10% Appraisal Cap Applies Regardless
Here’s the part that matters even if your MUD hasn’t opted in. Once your homestead exemption is approved, the appraisal district can’t raise your home’s appraised value by more than 10% over the prior year, plus the value of any new improvements you built.4State of Texas. Texas Tax Code 23.23 – Limitation on Appraised Value of Residence Homestead
The cap sits on the appraised value itself, not on any one entity’s share. Because your MUD, your school district, and your county all multiply their tax rates against that same value, the cap slows the growth of every line on your bill. In a fast-appreciating neighborhood, that protection often outweighs the dollar-amount exemptions.
How to Tell if Your MUD Adopted One
Look at your annual property tax statement. Each taxing entity has its own row with a “taxable value” column. If the MUD row shows a taxable value lower than your appraised value, the exemption is in effect. If the MUD row matches your appraised value while the school district row is $100,000 less, your MUD hasn’t adopted the optional exemption.
To confirm, call your county appraisal district. They can tell you which local-option exemptions each entity on your bill has voted to grant.
Larger Exemptions for Seniors, Disabled Homeowners, and Veterans
Some homeowners qualify for exemptions that can meaningfully cut, or in one case eliminate, the MUD portion of the bill.
Age 65 or Older
School districts must add another $10,000 on top of the standard $100,000 for homeowners 65 and older. MUDs and other non-school units may adopt an additional exemption of at least $3,000 for this age group, but only if the board votes to.5Texas Comptroller of Public Accounts. Property Tax Exemptions
One boundary to be aware of: the tax-ceiling freeze that locks total taxes at the amount owed the year a homeowner turns 65 applies only to counties, municipalities, and junior college districts under Section 11.261. MUDs are not included.6State of Texas. Texas Tax Code 11-261 – Limitation of County, Municipal, or Junior College District Tax on Homesteads of Disabled and Elderly Your MUD tax can still rise even after the freeze takes effect elsewhere.
A surviving spouse age 55 or older may keep the deceased spouse’s age-65 exemption if the spouse was eligible at death and the survivor still lives in the home.
Disabled Homeowners
Disabled homeowners get the same additional school district exemption as those 65 and older, and MUDs that have opted in may offer a disability exemption of at least $3,000. The same Section 11.261 boundary applies here too: the tax ceiling doesn’t reach MUDs.
100% Disabled Veterans
Veterans with a 100% disability rating or individual unemployability determination from the U.S. Department of Veterans Affairs are exempt from tax on the full appraised value of their home. This one is mandatory across every taxing jurisdiction, so it wipes out the MUD portion whether or not the MUD adopted any other exemption.5Texas Comptroller of Public Accounts. Property Tax Exemptions A surviving spouse who hasn’t remarried may also qualify.
Filing the Application
You file once. After the appraisal district approves it, the exemption stays in place as long as you own and occupy the home as your primary residence. The district reviews eligibility at least once every five years.
Use Form 50-114 from your county appraisal district. You’ll need your name, date of birth, and Texas driver’s license or state ID number, the property’s physical address, the date you began living there as your primary residence, and a copy of your driver’s license or state ID showing that address. Heirs who inherited a home without being named on the deed have extra requirements, including an ownership affidavit on Form 50-114-A.7Texas Comptroller of Public Accounts.

Deadlines
