San Patricio County Property Tax

San Patricio County property tax comes in two numbers that are easy to confuse. The county's own adopted rate is $0.409761 per $100 of value for the 2025 tax year - and it is only the San Patricio County government's portion. Your actual bill is the sum of every overlapping taxing unit that covers your parcel: your school district, your city (if any), and the county. Combined, the typical total effective rate in San Patricio County is about 1.53% of market value - an estimate from Census ACS 2023 5-year data (median real estate taxes paid $2,754 divided by median home value $180,400). Because the mix of taxing units differs from parcel to parcel, there is no single "San Patricio County rate" for a full bill; the figures below are worked examples.

San Patricio County's own rate of $0.409761 is made up of a maintenance-and-operations rate ($0.372516) and a debt (I&S) rate ($0.037245). There is no countywide hospital or community-college taxing district; a San Patricio County Drainage District ($0.055063) applies in its service area only, so it is not part of the representative Portland stack below. Portland, on the north shore of Corpus Christi Bay, is the county's largest city and its stretch around Gregory anchors a major petrochemical and industrial corridor; Sinton is the county seat.

Rates from the San Patricio County Truth-in-Taxation 26.16 summary (2025 tax year). This example is for a City of Portland / Gregory-Portland ISD parcel; your total depends on your city and school district. Other school districts include Sinton ISD ($1.235200), Ingleside ISD ($0.825814), Aransas Pass ISD ($0.808800), Odem-Edroy ISD ($1.185000), Taft ISD ($1.241600), and Mathis ISD ($1.159400). Unincorporated Gregory-Portland ISD parcels pay no city rate (about $1.514361 combined). A San Patricio County Drainage District ($0.055063) applies in part of the county.

Where your property-tax dollar goes

Gregory-Portland ISD ~49.5% City ~32.2% County ~18.3%

On a typical City of Portland / Gregory-Portland ISD parcel, Gregory-Portland ISD is about 49.5% of the nominal bill ($1.1046 / $2.2333 nominal total), the City of Portland about 32.2%, and San Patricio County about 18.3%. Percentages are rounded and use the nominal posted rates before any exemption - after the $140,000 school-district homestead exemption the taxable amount drops sharply, which is part of why the county's typical effective rate (about 1.53%) sits below the nominal stacked rate (about 2.23%).

Who appraises, bills, and collects in San Patricio County

• The San Patricio County Appraisal District sets appraised values, processes homestead exemptions, and runs protests, at sanpatcad.org.
• The San Patricio County Tax Assessor-Collector collects the property tax and also handles vehicle registration and titling, at sanpatriciocountytx.gov (pay online at actweb.acttax.com).

For value questions, start with the appraisal district; to pay, start with the San Patricio County Tax Assessor-Collector.

Homestead exemption, the 10% cap, and key dates

If you own and occupy your home as your principal residence on January 1, you can claim a residence homestead exemption, and you generally apply through the San Patricio County Appraisal District. For a Gregory-Portland ISD parcel, the statewide school-district exemption removes $140,000 from the value the school district taxes for the 2025 tax year. If the owner is 65 or older, an additional $60,000 ISD exemption applies.

Some San Patricio County cities also grant local-option homestead exemptions, but the exact per-unit amounts vary and were not fully extracted in this pass. Because those interact with each unit's own value, the calculator below models only the statutory $140,000 school-district homestead and treats its output as the conservative (high) end - a real over-65 homestead bill is lower. Confirm the exact exemptions on your account with the San Patricio County Appraisal District.

Separately, the 10% homestead appraisal cap limits how much your homestead's appraised (taxed) value can rise to 10% per year, not counting new improvements. The cap applies to the appraised value used for your bill, not the market value the appraisal district sets, and it starts the year after you first qualify for the homestead exemption.

Key dates: payment is due January 31 and unpaid amounts become delinquent February 1. The statewide protest deadline is May 15 or 30 days after your appraisal notice is delivered, whichever is later. Texas Tax Code Section 1.06 rolls any deadline that falls on a weekend or holiday to the next business day. We were not able to extract a San Patricio County-specific delinquent penalty-and-interest schedule from an official source in this pass, so no penalty percentages are stated on this page.

How to protest your appraisal

Protests go to the San Patricio County Appraisal District, which publishes its protest procedures and deadlines and runs the property search and appeals process. File and track everything at sanpatcad.org. Some private firms offer to handle protests for a percentage of any tax savings; such firms exist and charge a contingency fee, but we do not cite any savings figure or success rate as fact - results vary by parcel and year.

Vehicle Taxes in Texas

Unlike many states, Texas does not levy an annual value-based property tax on cars or other vehicles. There is no yearly "car tax" bill in San Patricio County. Instead, vehicle taxes in Texas work two ways:

• One-time motor-vehicle sales/use tax of 6.25% at purchase. For a private-party sale, the tax is charged on the greater of the actual sales price or 80% of the vehicle's Standard Presumptive Value (SPV). A vehicle received as a gift is taxed at a flat $10 instead.
• A flat annual registration fee (plus any local add-ons), which is a fixed fee, not a tax on the vehicle's value. In San Patricio County you register and title through the San Patricio County Tax Assessor-Collector.

So if you searched for a Texas car or vehicle sales tax, the answer is the one-time 6.25% charged when the vehicle is titled - there is no recurring vehicle property tax to budget for each year.

San Patricio County Sales Tax

The combined sales tax rate in the City of Portland is 8.25% - the Texas maximum. It is made up of the 6.25% state rate plus a 2.00% City of Portland rate. San Patricio County does not levy its own county sales tax, so outside a city the rate is just the 6.25% state rate. Texas law caps the total local portion at 2.0%, so once the city's 2.00% is applied, no further local rate can stack on top - which is why 8.25% is the maximum combined sales tax here.

City of Portland (San Patricio County) sales tax components

Component	Rate
Texas state rate	6.25%
City of Portland (local)	2.00%
Combined rate	8.25%

The 2.00% local share is the maximum Texas allows and here is the City of Portland rate; San Patricio County levies no county sales tax, so outside city limits the rate is 6.25%. The exact city-versus-economic-development split of the Portland local rate varies. Groceries and most unprepared food are exempt from sales tax.

Real Example: a $180,400 Portland Home

Here is how the numbers flow on a representative $180,400 City of Portland / Gregory-Portland ISD home (the county median value) with a homestead exemption (owner under 65), applying only the school-district homestead to the school unit:

• Market value: $180,400.
• Homestead exemption: the $140,000 school-district exemption drops the Gregory-Portland ISD taxable value to $40,400. The other units tax the full $180,400 in this simplified example.
• Stacked total: school $40,400 × 1.104600% = ~$446; city $180,400 × 0.718946% = ~$1,297; county $180,400 × 0.409761% = ~$739.
• Estimated annual bill: about $2,482 per year.
• Monthly equivalent: about $207 per month.
• Effective rate: about 1.38% of market value in this simplified example.

How this compares to the county-wide median. The Census ACS county-wide median bill is about $2,754 (roughly 1.53% effective). This Portland city example lands a little below it because it applies the school homestead on a median-value home. A homesteaded parcel with no city rate (school + county, roughly $1,185 on the same $180,400 value) would pay closer to 0.66%, and a real over-65 homestead - with the extra $60,000 school exemption and the school-tax ceiling - would be lower still. A non-homestead $180,400 Portland parcel would pay closer to the full nominal ~2.23%, or about $4,029.

Limitations:

• Your total varies by school district and city; a Sinton, Ingleside, Aransas Pass, Odem-Edroy, Taft, Mathis, or unincorporated parcel uses a different stack.
• Local-option city homestead exemptions (and over-65, disability, and disabled-veteran exemptions) are not modeled in the simplified example above; this example applies only the school-district homestead, so a real homesteaded city bill is lower.
• The San Patricio County Drainage District ($0.055063) is not included in the representative stack and applies only in its service area.
• San Patricio County's exact delinquent penalty-and-interest schedule was not available from an official source in this pass and is not stated here.
• This is an estimate, not a parcel-exact bill. The typical effective rate is a Census ACS estimate, not a guaranteed rate.
