San Angelo Property Tax: Rates, Exemptions, and Protests

Property owners in San Angelo pay taxes to several overlapping jurisdictions, and the combined bill adds up to roughly 1.3 percent of a home’s assessed value. The San Angelo Independent School District levies $1.07060 per $100 of valuation, the City of San Angelo adds $0.7947 per $100, and Tom Green County plus any applicable special districts stack on top of those.¹² The school district is almost always the largest single line on your bill, and exemptions, protests, and payment timing are where you have real room to lower what you owe.

Who Taxes Your Property and at What Rate

Your San Angelo tax bill is a bundle of separate bills from independent taxing entities, each setting its own rate every year.

San Angelo ISD: $1.07060 per $100 of valuation, split between $0.71220 for maintenance and operations and $0.35840 for debt service.²
City of San Angelo: $0.7947 per $100 of valuation, funding municipal services like police, fire, streets, and parks.¹
Tom Green County: an annually adopted rate covering county roads, the sheriff’s department, and other county services.
Special districts: depending on where the property sits, it may fall within the Tom Green County Fresh Water Supply District No. 2 or another utility district with its own small levy.

Each entity sets its rate through public hearings and formal votes under Chapter 26 of the Texas Tax Code before the start of the tax year.³

How Your Property Is Appraised

The Tom Green County Appraisal District determines the market value of every property in the county as of January 1 each year. The appraisal district does not set tax rates; it sets the value that taxing entities apply their rates to. A Notice of Appraised Value arrives in the spring showing the updated figure, and that number drives the fall tax bill.

If the home has a homestead exemption on file, state law caps how fast the appraised value can rise. Under Section 23.23 of the Tax Code, the appraisal district cannot increase a homestead’s appraised value by more than 10 percent per year, plus the value of any new improvements.⁴ The cap takes effect the second year after you qualify, so filing promptly matters. Even if comparable sales suggest a 25 percent jump in market value, the taxable value is limited to the 10 percent annual increase. The district still records the full market value in its files, and that number becomes relevant if you sell or lose the exemption.

Exemptions That Lower Your Bill

Exemptions reduce the taxable value of your home before any rate is applied, so savings flow through every jurisdiction that honors the exemption.

General Residence Homestead

Any homeowner using the property as a primary residence can claim the general homestead exemption. For school district taxes, this removes $140,000 from the appraised value. On a home appraised at $250,000, the school district would tax only $110,000. Cities and counties may offer an optional percentage-based homestead exemption of up to 20 percent of appraised value, with a floor of $5,000.⁵

Age 65 and Older or Disabled

Homeowners 65 or older, or those with a qualifying disability, get an additional $60,000 off the appraised value for school district taxes on top of the general $140,000.⁵ Other jurisdictions may adopt their own additional exemption of at least $3,000 for over-65 or disabled homeowners, and many set higher amounts.

The over-65 group also benefits from a school district tax ceiling. The year you turn 65 and qualify, your school district tax amount is locked in. Even if the home’s value rises later, the school district portion of the bill will not exceed that frozen figure. Some cities and counties offer a similar ceiling on their portion.

Disabled Veterans

Veterans with a service-connected disability rating from the U.S. Department of Veterans Affairs receive a partial exemption based on their rating:⁶

10 to 29 percent rating: up to $5,000 off appraised value
30 to 49 percent rating: up to $7,500 off appraised value
50 to 69 percent rating: up to $10,000 off appraised value
70 to 100 percent rating: up to $12,000 off appraised value

Veterans rated at 100 percent disabled, or classified as individually unemployable, qualify for a complete exemption on their homestead. The entire appraised value is removed from taxation by every jurisdiction. A surviving spouse who was married to the veteran at the time of death can continue receiving that exemption as long as they do not remarry and continue living in the home.⁷

How to Apply

File exemption applications with the Tom Green County Appraisal District using Form 50-114, available on the Texas Comptroller’s website or through the appraisal district’s office.⁸ The general filing deadline is April 30, but late applications are accepted for up to two years after the deadline for most exemptions, and up to five years for the 100 percent disabled veteran exemption.⁹

You will need a Texas driver’s license or state-issued ID showing the property address and must confirm the home is your principal residence.⁸ If your ID does not yet show the homestead address, the form includes a process to request a waiver from the chief appraiser. Disabled veteran applicants should include documentation from the VA showing their rating.

When and How to Pay

Tax bills go out in October and are due by January 31. The Tom Green County Tax Assessor-Collector handles payments, not the appraisal district. You can pay online through the appraisal district’s portal with a credit card or electronic check, though card payments carry a convenience fee.¹⁰ Mail and in-person payments are also accepted at the county tax office.

Homeowners who are 65 or older, disabled, or disabled veterans with a homestead exemption can split the bill into four equal installments. The first is due before February 1, with the rest due before April 1, June 1, and August 1. As long as each payment is made on time and the tax office is notified with the first installment, no penalty or interest accrues.¹¹ Miss an installment and a 6 percent penalty plus monthly interest applies to the unpaid amount.

What Late Payment Costs

Taxes unpaid on February 1 are delinquent, and the charges escalate quickly:¹²

February 1: 6 percent penalty plus 1 percent interest, for 7 percent total.
March through June: an additional 1 percent penalty and 1 percent interest each month.
July 1: the penalty resets to a flat 12 percent of the original tax amount regardless of how many months have passed, and interest continues at 1 percent per month.

If the taxing unit has contracted with a collections attorney, an additional penalty of up to 20 percent of the total tax, penalty, and interest can be added once the account reaches July 1.¹³ Interest keeps accruing at 1 percent per month indefinitely, with no cap. On a $5,000 tax bill, waiting until July means owing the original tax plus roughly $600 in penalty, over $300 in interest, and potentially another $1,000 or more for the attorney collection fee.

Protesting Your Appraised Value

If the Notice of Appraised Value looks too high, you can protest. The deadline is May 15 or 30 days after the appraisal district mails the notice, whichever is later.¹⁴ File a written protest with the Tom Green County Appraisal District stating your grounds, usually that market value is set too high or the property is valued unequally compared to similar homes.

Most protests begin with an informal meeting with a staff appraiser, and many settle there. Useful evidence includes recent sales data for comparable homes in your neighborhood, contractor estimates for needed repairs, and photographs showing condition issues the district may not have accounted for. If no agreement is reached, the case goes to the Appraisal Review Board, a panel of local citizens who hear testimony from both sides and issue a binding determination. If you disagree with that decision, you can appeal to state district court, pursue binding arbitration, or in some cases petition the State Office of Administrative Hearings.¹⁴

Business Personal Property Renditions

Business owners face an obligation residential homeowners do not. If you own tangible business property such as equipment, inventory, furniture, or vehicles, you must report it to the Tom Green County Appraisal District each year. The filing deadline is April 15, with a written extension available to May 15 and potentially an additional 15 days beyond that for good cause.¹⁵

The rendition reflects ownership and value as of January 1. A late or missed rendition triggers a 10 percent penalty on the taxes owed on the property. Filing a false rendition on purpose carries a 50 percent penalty. The chief appraiser may waive the late-filing penalty for good cause, but that is an exception, not a plan.

If Taxes Go Unpaid Long Enough

Years of unpaid property taxes can lead to a tax foreclosure lawsuit. If the taxing unit wins and the property goes to a tax sale, homestead owners still get a second chance. Under Section 34.21 of the Tax Code, if the property was your residence homestead when the lawsuit was filed, you have two years from the date the buyer’s deed is recorded to redeem.¹⁶

Redemption is expensive. You must repay the buyer everything they paid at the sale, plus recording fees and any taxes, penalties, and interest they paid on the property afterward. On top of that, you owe a 25 percent premium if you redeem within the first year, or a 50 percent premium in the second year.¹⁶ Properties that were not homesteads or agricultural land at the time of the suit generally have no redemption period at all, and the sale is final.
