South Padre Island, TX: Property Tax Guide

The Real Numbers: What South Padre Island Actually Pays

Ownwell, an independent property-tax data aggregator that analyzes public assessment and sales records across Texas counties, puts South Padre Island's median effective property tax rate at 1.71% and its median home value at $428,825 -- the highest median home value of any community in Cameron County. On that base, Ownwell calculates a median annual property tax bill of $6,669 for South Padre Island, again the highest in the county, well above Cameron County's own countywide median tax bill of $1,458 and above the U.S. national median of $2,400. Separately, Ownwell cites a South Padre Island nominal tax rate of roughly $2.001669 per $100 of assessed value -- that figure and the 1.71% effective rate describe two different things (a nominal per-$100 rate applied to assessed/taxable value after exemptions, versus an effective rate calculated against full market value), and this page states both honestly rather than picking whichever sounds better.

These are real, source-attributed numbers, not a vague range -- but they come from an aggregator analyzing public records, not from the Cameron County Appraisal District (CCAD) itself, and Cameron County's own median tax bill of $1,458 reflects a countywide mix that includes far less expensive inland and rural areas, not a like-for-like comparison to island property. Before budgeting a purchase, pull the actual current tax rate and assessed value for the specific parcel directly from the Cameron County Appraisal District's own records or its online property search tool, and don't anchor your budget to a county- or city-wide median.

Real, Local-Option Exemptions That Actually Lower a South Padre Island Bill

Beyond the statewide homestead exemptions, South Padre Island and Cameron County both offer real, specific local-option exemptions that a full-time, homesteaded owner should actually claim, and that a lot of generic relocation content skips entirely. The City of South Padre Island offers its own local $15,000 homestead exemption on top of the statewide school-district exemption, and a separate 20% local-option exemption applies to Laguna Madre Water District and City of South Padre Island taxes on a qualifying homesteaded property. Cameron County, separately, offers its own $12,000 additional exemption for homeowners age 65 and older, on top of the statewide over-65 exemption described below, per the South Padre Island Economic Development Corporation's own published tax information and corroborating property-tax guidance sources.

These local exemptions apply on top of, not instead of, the statewide homestead and over-65/disabled exemptions -- meaning a full-time, homesteaded South Padre Island owner age 65 or older can potentially stack the state's $140,000 general exemption, the state's $60,000 additional over-65 exemption, the city's own $15,000 homestead exemption, the 20% Laguna Madre Water District/City exemption, and the county's $12,000 over-65 exemption, each applying to the specific taxing entity it's tied to. As with everything else on this page, the exact dollar effect depends on the specific parcel's assessed value and which taxing entities apply to it -- confirm the current, specific stack of exemptions available to your property directly with the Cameron County Appraisal District and the City of South Padre Island.

Why South Padre Island Runs So Much Higher Than the Rest of the County

The gap between South Padre Island's roughly $6,669 median tax bill and Cameron County's roughly $1,458 countywide median isn't a tax-rate anomaly -- it's mostly a home-value story. Cameron County includes large stretches of far less expensive inland Rio Grande Valley housing stock, while South Padre Island is the priciest real estate in the county by a wide margin, per Ownwell's own value comparisons ($428,825 median value on the island versus much lower medians elsewhere in the county, down to a reported $219 median tax bill in Laguna Heights at the low end). A comparatively high tax rate applied to a comparatively high assessed value produces the county's highest tax bills, which is a straightforward mechanical outcome, not evidence of a uniquely punitive island-specific levy.

Like anywhere in Texas, a South Padre Island tax bill is the sum of several separately set levies stacked on one bill -- Cameron County's own rate, the applicable school district's rate, the City of South Padre Island's municipal rate, and any special district that applies to the specific parcel. This page does not itemize the current mill-by-mill breakdown for each of those entities, since exact current rates for each taxing authority were not independently confirmed line by line this research pass. Pull the parcel-specific breakdown directly from the Cameron County Appraisal District or Cameron County Tax Assessor-Collector's office, which show the exact combination of entities and rates that apply to a specific address.

Texas's 2025-2026 Homestead Exemption Increase -- and Why Most South Padre Island Owners Won't Get It

Texas voters approved two separate constitutional amendments on the November 2025 ballot that together raise homestead exemptions substantially. Proposition 13 (Senate Bill 4) raised the general school-district homestead exemption from $100,000 to $140,000. A separate amendment, Proposition 11 (Senate Bill 23), raised the additional exemption available to qualifying homeowners age 65 or older or with a qualifying disability from $10,000 to $60,000 -- meaning those owners can now exempt up to $200,000 of their home's value ($140,000 general plus $60,000 additional) from school-district taxation, per Ballotpedia's coverage of both measures. These are real, meaningful, recently enacted changes, and they're worth knowing precisely because of the market they apply to: a genuine, permanent, owner-occupied primary residence with a filed homestead exemption on file with the Cameron County Appraisal District.

The catch for South Padre Island specifically is the same one that shows up in other heavily second-home and vacation-rental Gulf and coastal markets: a large share of South Padre Island's housing stock is not anyone's primary residence. Second homes, investment condos, and short-term vacation rental units -- which make up a substantial and visible part of this market, as covered on this site's vacation rental investment page -- do not carry a homestead exemption and do not benefit from either the $140,000 school exemption or Texas's related homestead assessment-increase cap (which limits annual increases in a homesteaded property's taxable value to 10% once the exemption has applied for a full year). If you're buying on South Padre Island as a second home, an investment property, or a rental, do not assume your tax bill will reflect the lower, homestead-protected figure a full-time-resident neighbor might see on a comparable property -- confirm with the Appraisal District whether the specific property you're considering currently carries a homestead exemption, since that materially affects the bill you'll actually pay.

No State Income Tax Is Real -- But It Is Not the Whole Trade-off

Texas genuinely has no state income tax, and that's a real, structural, statewide fact that applies on South Padre Island exactly as it does everywhere else in Texas. It's also frequently cited by relocation and retirement content as a reason Texas coastal property is a tax-friendly buy, and in isolation that's true. What that framing often leaves out is that Texas leans more heavily on property tax to fund schools, counties, and municipalities specifically because there's no income tax revenue to draw on instead -- and South Padre Island, as the highest-value real estate in Cameron County, sits at the top of that structure's actual dollar impact. A buyer moving from a state with both income tax and property tax may still come out ahead overall, but a buyer comparing South Padre Island's property tax bill in isolation to a lower-property-tax, higher-income-tax state should run the full math for their own situation rather than assuming 'no income tax' automatically means 'lower overall tax burden.'

This is especially relevant for anyone considering South Padre Island for retirement or as a Winter Texan snowbird property, since income-tax-free framing is common in retirement-relocation marketing generally. The retirement page on this site covers the over-65 homestead exemption mechanics specifically; here, the honest summary is that no income tax is real, the property tax bill on a South Padre Island home is also real and comparatively high, and a full relocation tax comparison needs both sides of that ledger, not just the more flattering one.

Assessed Value vs. Market Value: What Changes When You Buy

Texas counties reassess property value, and a change in ownership is one of the events that can trigger a reassessment closer to current market value, particularly for a property that hasn't had a homestead exemption keeping its taxable value capped. Given that Redfin's own recent market data shows South Padre Island home prices still moving -- a median sale price of $518,690 as of May 2026, up 9.3% year over year, per Redfin's South Padre Island housing-market page, a cooler pace than the market showed in late 2025 -- a property's currently listed assessed value on file with the Cameron County Appraisal District may lag meaningfully behind what you're about to pay for it. Don't assume the seller's current tax bill, calculated against their existing assessed value, predicts what your bill will look like the year after you close.

This page does not state a specific reassessment timeline, appeal deadline, or protest procedure for Cameron County, since exact current procedural details were not independently confirmed this research pass beyond the general Texas framework. If minimizing or accurately forecasting your first-year tax bill matters to your purchase budget, ask the Cameron County Appraisal District directly, before closing, how the specific parcel is likely to be reassessed and on what timeline.

What This Means When You Budget a Purchase

Three things to actually do, not just know. First, treat South Padre Island's ~1.71% effective rate and ~$6,669 median tax bill as real, sourced, directional numbers -- not as a substitute for pulling your specific parcel's actual current assessed value and tax rate from the Cameron County Appraisal District before you make an offer. Second, if the property is a second home, rental, or investment property -- the more typical case on this island -- do not assume it will carry a homestead exemption or benefit from the 2025-2026 $140,000 exemption increase; confirm its current exemption status directly. Third, run the full no-income-tax-versus-property-tax comparison for your own financial situation rather than relying on the 'Texas has no income tax' framing alone, since South Padre Island's property tax bills sit at the top of Cameron County's range for a reason. None of this is tax advice; a Texas property tax consultant, CPA, or attorney familiar with Cameron County specifics should review the actual numbers on any purchase before you rely on them.
