Bexar County
property tax, explained.
A San Antonio-area property’s tax bill can include several units with different exemptions. Start with the jurisdictions listed in the Bexar Appraisal District record, then reconcile each unit to the county’s rate and exemption table for the same year.

Follow the dollars
A unit-specific exemption changes the total
A hypothetical unit taxing $280,000 at $0.30 per $100 produces $840. A second unit taxing $200,000 at $1.00 per $100 adds $2,000, for $2,840 across those two lines. Applying their combined 1.30 rate to $280,000 would incorrectly give $3,640. These are illustrative rates and values.
Annual value-based tax for one unit before ceilings or credits. Excludes other units, penalties, interest and amounts already paid.

Let the appraisal record identify the taxing jurisdictions
The county FAQ assigns property identification, value, exemptions and taxing jurisdictions to the Bexar Appraisal District. Use its account record to identify the units that apply, rather than assuming every San Antonio mailing address shares one tax package.
Save the account number, tax year and taxable value for each unit. Bring value or exemption discrepancies to the appraisal district and keep the corrected record for your bill comparison.
Read the rate table as separate rows
The county’s rate directory links rate information. Its 2025 official table illustrates the separate unit codes, rates, exemption columns and freeze information. That table is labeled 2025 and should not be silently reused for a later bill.
Match each row to the parcel’s jurisdictions and the applicable adopted year. Check a unit’s taxable base before adding its rate to another unit’s rate. A table of available exemptions is not proof that every listed benefit was approved for your account.
Separate a value exemption, a ceiling and a deferral
The FAQ distinguishes exemptions, qualifying tax limitations and deferrals. They affect different parts of the process: taxable value, tax charged, or the timing of payment. A deferral does not cancel the underlying obligation.
This calculator only checks the value-times-rate step. Keep any ceiling or credit as a separate reconciliation item. Do not infer eligibility from age alone or use the gross illustration as a payoff amount.
An installment plan needs its own eligibility and schedule
The county’s payment-plan guidance describes half-payment, qualifying quarterly and ten-month options. Check the current plan instructions and your account’s eligibility before splitting a bill into arbitrary monthly payments.
Keep the issued statement, plan confirmation and receipts together. Confirm that escrow payments reached the correct account and year. A calculator total cannot establish a plan enrollment, receipt or remaining balance.
Sources and review scope
Property Tax Almanac checked these official sources on September 26, 2026. Illustrative inputs are labeled; this review does not establish every parcel’s current rate or individual eligibility.

- Tax-rate directory — Rate-setting and official resources.
- 2025 rates and exemptions — Historical table structure; no current default rate inferred.
The calculator divides the taxable base by 100, multiplies by the entered rate and rounds to cents. It is a bill-checking tool, not an official tax determination. Other site tools may use different benchmark assumptions.
