Property tax rates in Rosharon, TX, typically run between 2.0% and 3.5% of a home’s assessed value, with the exact figure depending on which school district, special districts, and municipal utility district cover your parcel.1Texas Almanac. Rosharon Rosharon is unincorporated, so there is no city tax, but Brazoria County, your school district, a drainage district, an emergency services district, and often a MUD each levy their own rate on top of each other. Two homes a mile apart can have noticeably different totals.
Who Taxes a Rosharon Property
Because Rosharon has no city government, your bill is built by layering every overlapping jurisdiction that serves your address. Every property owner pays into at least three entities: the Brazoria County general fund, the county road and bridge fund, and one of the area school districts. Most properties also sit inside a drainage district and one of the Brazoria County Emergency Services Districts, which fund fire protection and EMS.
Brazoria County’s combined rate for general operations and road and bridge has historically fallen in the range of $0.34 to $0.38 per $100 of assessed value. Drainage and ESD rates are smaller per-$100 charges and vary by location: a home near Rosharon might sit in Brazoria County ESD No. 3, while a home a few miles away falls under a different ESD at a different rate. Together, county and special-district levies make up the smaller share of a Rosharon tax bill.
Each entity adopts its rate annually, and the Brazoria Central Appraisal District publishes the certified rates for the year.2Brazoria Central Appraisal District. 2025 Tax Rates Rates shift modestly year to year, so confirm the current figures with the appraisal district or the Brazoria County Tax Office before budgeting.
School District Rates Drive Most of the Bill
School taxes are the largest single slice of almost every Rosharon tax bill. Properties generally fall within either Alvin Independent School District or Angleton Independent School District. Alvin ISD’s current total tax rate is $1.17 per $100 of assessed value.3Alvin Independent School District. Bond Q&A Angleton ISD sets its own rate based on that district’s maintenance and debt service needs, and the two are not identical.
Which district your address falls in makes a real difference. On a $350,000 home, even a $0.10 gap between the two school rates works out to $350 per year.
Municipal Utility Districts Can Push the Rate Much Higher
Many of the master-planned communities and newer subdivisions around Rosharon were built inside Municipal Utility Districts. A MUD issues bonds to pay for the roads, water lines, sewer mains, and drainage a new development needs, then levies a property tax on every lot in the district to repay those bonds over decades. MUD rates in the Brazoria County area commonly run from roughly $0.50 to over $1.00 per $100 of assessed value, depending on how much debt the district still carries.
This layer is where Rosharon tax bills climb sharply. A homeowner outside any MUD, paying only county and school taxes, might see an effective rate near 1.6% to 1.8%. A homeowner inside a heavily indebted MUD can face a combined rate above 3.0%. The MUD rate tends to drop as bonds are retired, but the payoff timeline can stretch 20 to 30 years. If you are shopping, the MUD rate deserves as much attention as the purchase price.
Estimating Your Own Bill
Your tax bill for each jurisdiction equals the assessed value, minus any applicable exemptions, divided by 100, then multiplied by that entity’s rate. The Brazoria Central Appraisal District assigns a market value to every property each year.4Texas Comptroller of Public Accounts. Valuing Property A homestead exemption caps how fast the taxable value can climb, so your assessed value may be lower than market.
Take a $350,000 home with the $100,000 school homestead exemption and a combined rate of $2.50 per $100:
- School portion: ($350,000 − $100,000) ÷ 100 × $1.17 = $2,925
- County and special districts: $350,000 ÷ 100 × $0.55 = $1,925 (using a hypothetical combined rate)
- MUD, if applicable: $350,000 ÷ 100 × $0.75 = $2,625
- Estimated total: roughly $7,475
Your actual numbers depend on the specific rates and exemptions tied to your parcel. The Brazoria County Tax Office runs an online tax estimator where you can plug in your exact jurisdictions and exemptions.5Brazoria County Tax Office. Tax Estimator
Exemptions That Lower the Rate You Actually Pay
Texas offers several property tax exemptions under Tax Code Chapter 11, and claiming the ones you qualify for is the easiest way to reduce your annual bill. Applications go to the Brazoria Central Appraisal District.6Brazoria Central Appraisal District. Brazoria Central Appraisal District
Residence Homestead
Any homeowner using the property as a primary residence can claim the general homestead exemption. For school district taxes, it removes $100,000 from the appraised value before the rate is applied.7State of Texas. Texas Tax Code 11.13 – Residence Homestead County taxes get a smaller $3,000 exemption by default, though local governing bodies can vote to offer more. A proposal advanced in the Texas legislature in 2025 (Senate Bill 4) would raise the school exemption to $140,000, and to $150,000 for seniors; check with the appraisal district for the amount in effect this tax year.
The homestead designation also triggers a 10% annual cap on how fast the assessed value can climb. Under Tax Code Section 23.23, the appraisal district cannot increase a homestead’s appraised value by more than 10% over the prior year, plus the value of any new improvements.8State of Texas. Texas Tax Code 23.23 – Limitation on Appraised Value of Residence Homestead In a rising market, that cap can keep taxable value well below market value for years.
Over-65 and Disability
Homeowners 65 or older, or those with a qualifying disability, receive an additional $10,000 exemption from school district taxes on top of the general homestead amount.7State of Texas. Texas Tax Code 11.13 – Residence Homestead More importantly, turning 65 triggers a school district tax ceiling: the dollar amount you owe the school district the first year you qualify becomes the most you will ever pay in school taxes on that home, even if values or rates rise. If you move to another homestead in Texas, the ceiling transfers proportionally.
Disabled Veteran
Veterans with a service-connected disability rating from the VA receive exemptions scaled to their rating:
- 10% to 29% disability: $5,000 off appraised value
- 30% to 49%: $7,500 off
- 50% to 69%: $10,000 off
- 70% to 99%: $12,000 off
- 100% disability: full exemption from all property taxes
A Rosharon homeowner with a 100% VA rating owes nothing in property taxes regardless of the home’s value or how many entities have jurisdiction.9Texas Veterans Commission. Property Tax Exemptions Available to Veterans Per Disability Rating Surviving spouses of veterans who died in service or from a service-connected condition may also qualify; the rules are specific, so confirm with the appraisal district.
Protesting the Appraised Value
If the Brazoria Central Appraisal District’s notice of appraised value looks too high, you can challenge it. Protesting is free, and every dollar the appraisal district takes off your value reduces every entity’s tax on that property for the year.
The deadline is May 15, or 30 days after the appraisal district mails your notice, whichever is later.10State of Texas. Texas Tax Code 41.44 – Notice of Protest Miss that window and you can still file a late protest before the Appraisal Review Board approves the records (usually mid-July), but only if the board finds good cause for the delay.11Brazoria Central Appraisal District. Appeals
The appraisal district accepts protests through its online eProtest system or on a paper form mailed or dropped off at the office in Angleton. Most protests begin with an informal settlement offer from an appraiser, and many resolve there. If you cannot agree, the case moves to a formal hearing before the Appraisal Review Board. Recent sale prices of comparable homes in your neighborhood are the single most effective evidence to bring.
Payment Deadline and Late Penalties
Texas property taxes are due by January 31 of the year following the tax year. Miss that date and penalties start immediately. A delinquent tax picks up a 6% penalty in February, plus 1% more for each month it remains unpaid through June. On July 1 the penalty jumps to a flat 12% regardless of how many months you are behind. Interest accrues at 1% per month the entire time the tax is unpaid.12State of Texas. Texas Tax Code 33.01 – Penalties and Interest
In dollar terms, an $8,000 bill left unpaid through July picks up roughly $1,560 in combined penalty and interest. Taxing entities can also turn the account over to a collections attorney, which adds further fees. If you cannot pay in full by January 31, Brazoria County offers installment agreements, and homeowners over 65 or with a disability can defer payment entirely until the home changes hands.
