Galveston County property tax is calculated by taking your home’s appraised value as of January 1, subtracting any exemptions you qualify for, and multiplying the result by the combined rate of every taxing entity that covers your parcel. Those entities typically include the county, a school district, a city, and often a drainage, emergency services, community college, or municipal utility district on top. Combined effective rates can push past 2% of market value, which is why exemptions, deadlines, and protest rights matter.
How Your Bill Is Built
The Galveston Central Appraisal District sets a market value on every parcel each January 1.1State of Texas. Texas Tax Code 41.44 – Notice of Protest Subtract the exemptions you qualify for and you have your taxable value. Each taxing unit then applies its own rate, expressed per $100 of taxable value. Add the results from every unit covering your property and you have your total bill.
Exemptions do not all apply to every taxing unit. The school district homestead exemption, for example, reduces only the value the school district taxes, not the value the county or city taxes. That is why one property can have several different taxable values on the same bill.

The Homestead Exemption
If you own your Galveston County home and live in it as your principal residence, you qualify for a residence homestead exemption under Texas Tax Code Section 11.13. Every Texas school district must grant a $140,000 exemption on the appraised value of a homestead.3Texas Comptroller of Public Accounts. Property Tax Exemptions The county adds a smaller $3,000 exemption for county tax purposes.4State of Texas. Texas Tax Code 11.13 – Residence Homestead Cities and other taxing entities may offer optional additional exemptions, but they are not required to.
To qualify, you need an ownership interest and must use the property as your principal residence. You can only claim one homestead exemption per year.4State of Texas. Texas Tax Code 11.13 – Residence Homestead The application requires a Texas driver’s license or state ID showing the property address, and it is filed with the Galveston Central Appraisal District, not the tax office.
Relief for Seniors, Disabled Homeowners, and Veterans
Homeowners 65 or older and homeowners with a qualifying disability get more than the standard homestead exemption. School districts must grant an additional exemption for these owners, and many cities and special districts offer optional additional amounts.3Texas Comptroller of Public Accounts. Property Tax Exemptions
The bigger benefit for most qualifying owners is the school tax ceiling. Once you qualify, your school district taxes are frozen at the amount paid in the first qualifying year and will not go up unless you add improvements such as a room addition or pool. Some cities also adopt a local tax ceiling.4State of Texas. Texas Tax Code 11.13 – Residence Homestead
Disabled veterans receive a separate exemption under Section 11.22, scaled to their VA disability rating:
- 10% to 29% disability: up to $5,000 off assessed value
- 30% to 49%: up to $7,500
- 50% to 69%: up to $10,000
- 70% or higher: up to $12,000
A surviving spouse of a qualifying disabled veteran keeps the same exemption amount the veteran received.5State of Texas. Texas Tax Code 11.22 – Disabled Veterans
Veterans with a 100% VA disability rating or a determination of individual unemployability receive a complete exemption on the total appraised value of their homestead under Section 11.131. That is zero property tax on the home.6Texas Comptroller of Public Accounts. 100 Percent Disabled Veteran and Surviving Spouse Frequently Asked Questions
When Taxes Are Due and How to Pay
Texas property taxes are due on receipt of the bill and become delinquent on February 1 of the following year.7State of Texas. Texas Tax Code 31.02 – Delinquency Date A bill mailed in October 2025 must be paid before February 1, 2026.
The Galveston County Tax Office accepts payment through several channels:8Galveston County, TX. Property Tax
- Online by e-check, debit card, or credit card through the county’s web portal (convenience fees apply)
- By phone at 1-800-420-1663 with a debit or credit card (bank fees apply)
- By mail with a check or money order and the payment coupon
- In person or in the yellow drop boxes outside every full-time county tax office branch
Penalties If You Pay Late
The cost of missing February 1 escalates quickly. A delinquent tax picks up a 6% penalty in the first month, plus 1% more each month through June, with interest accruing at 1% per month on top.9State of Texas. Texas Tax Code 33.01 – Penalties and Interest
July 1 is the hard cliff. Any tax still unpaid that day jumps to a 12% penalty regardless of how many months it has actually been delinquent, and monthly interest keeps running.9State of Texas. Texas Tax Code 33.01 – Penalties and Interest Once a taxing unit refers the account for collection, attorney fees can be added as well.
Taxes left unpaid can lead to a lawsuit and eventually a tax foreclosure sale. A former owner of a homestead sold at tax sale has two years to redeem the property: paying the purchase price plus 25% in the first year, or purchase price plus 50% in the second. Non-homestead properties get only a six-month redemption window.
Deferral and Installment Plans
Homeowners who are 65 or older, disabled, or qualifying disabled veterans can defer collection of their property taxes for as long as they own and live in the home. An affidavit filed with the Galveston Central Appraisal District under Section 33.06 stops any foreclosure suit or tax sale from moving forward.10State of Texas. Texas Tax Code 33.06 – Deferred Collection of Taxes on Residence Homestead of Elderly or Disabled Person or Disabled Veteran A tax lien remains on the property, and deferred taxes accrue interest at 5% per year. No penalty is charged during the deferral period.11Texas Comptroller of Public Accounts. Tax Deferral Affidavit Age 65 or Older or Disabled Homeowner The deferred balance plus interest comes due once you stop using the home as your residence.
The same groups can split the annual bill into four equal installments under Section 31.031. The first payment, with written notice to the taxing unit, must be made before February 1; the remaining three are due before April 1, June 1, and August 1.12State of Texas. Texas Tax Code 31.031 – Installment Payments of Certain Homestead Taxes A missed installment triggers a 6% penalty and 1% monthly interest on the unpaid portion, but the harsher general delinquency schedule does not apply.
Protesting Your Appraised Value
If you believe the appraisal district set your value too high, you have a right to protest. The written Notice of Protest is due by May 15 or 30 days after the appraisal district delivered your notice of appraised value, whichever is later.1State of Texas. Texas Tax Code 41.44 – Notice of Protest File through the appraisal district’s online eFile system or mail a paper form. Owners who miss the deadline can still get a hearing by showing good cause, at the Appraisal Review Board’s discretion.
The process usually starts with an informal meeting with a district appraiser. Bring evidence: recent sale prices of comparable homes, photographs of damage or conditions that reduce value, and an independent appraisal if you have one. Most protests settle at this stage because appraisers have room to adjust values when presented with solid comparable sales data.
If informal talks do not resolve things, the case goes to a formal hearing before the Appraisal Review Board. The board hears evidence from both sides and issues a binding written order setting the property’s value.
Options After the ARB
An unfavorable ARB order is not the final word. Property owners can request binding arbitration through the Texas Comptroller’s office if the determined value does not exceed $5 million; no value cap applies to homesteads. The request must be filed within 60 days of receiving the ARB’s order.13Texas Comptroller of Public Accounts. Regular Binding Arbitration Arbitration requires a deposit and tends to be faster and cheaper than court.
The other route is an appeal in district court, which generally makes sense only for high-value commercial parcels or complex valuation fights where the numbers justify hiring counsel. Whichever path you take, taxes must still be paid on time while the appeal is pending. You can pay the undisputed portion and contest the rest without losing appeal rights.
Federal Deduction for Property Taxes Paid
Property taxes paid to Galveston County and its taxing entities can be deducted on your federal return if you itemize, as part of the state and local tax (SALT) deduction. For 2026, the SALT cap is $40,400 for most filers, or $20,200 if married filing separately.14Internal Revenue Service. Tax Information for Homeowners That cap covers combined state income taxes, sales taxes, and property taxes.
The cap phases down for higher earners. Once modified adjusted gross income exceeds $505,000 for 2026, the cap gradually shrinks but cannot drop below $10,000. For many Galveston County homeowners, the standard deduction will exceed total itemized deductions in any event, so the SALT cap never comes into play. Run the numbers both ways before itemizing.
