Montgomery County
property tax, explained.
A Conroe, Montgomery or The Woodlands address does not identify every taxing unit on a property. Match the parcel to its school, municipal or township, utility and other district lines before estimating the total.

Follow the dollars
A district line can materially change the total
At a hypothetical $250,000 taxable value and $0.80 rate per $100, one taxing unit’s tax is $2,000. A separate hypothetical district with a $300,000 taxable value and $0.25 rate adds $750, for $2,750 across those two lines. Neither line represents a complete Montgomery County household bill.
Annual tax for one taxing unit only. Repeat using each other unit’s own taxable value and rate. Excludes ceilings, deferrals, special charges, penalties and interest.

Start with the parcel’s taxing-unit list
The Texas Comptroller’s Montgomery directory lists local school districts, cities, The Woodlands Township, municipal utility districts and other units. That list describes the county’s jurisdictions; it does not mean every unit taxes every property.
Use Montgomery Central Appraisal District’s property portal to identify the units associated with the parcel. Keep their names or codes with the tax-year values. Two similar homes can have different applicable districts, so a nearby listing’s tax total is not a substitute for this check.
Check exemptions separately for each unit
The Comptroller’s exemption guidance distinguishes school homestead relief from exemptions adopted by other local units. Use each unit’s resulting taxable value rather than subtracting one school exemption from every line.
Applications go to the appraisal district. Start with MCAD and verify the approved status on the record. A purchase price, market value, appraised value and taxable value can describe different stages of the calculation. The tool asks for the last of those for the particular taxing unit.
Confirm who collects each charge
The state directory separately lists active taxing units and units served by the county collector. Use the linked Montgomery County Tax Office to check the county-collected account; investigate any other collector identified on your statement.
For a complete annual comparison, record every applicable unit’s tax and then reconcile payments or adjustments. Paying one statement should not be taken as confirmation that every separately billed district is paid. The calculator is a line-item check, not an outstanding-balance lookup.
Resolve appraisal questions before treating them as billing errors
The official directory lists MCAD at 936-756-3354 and the Tax Assessor-Collector at 936-539-7897. Contact MCAD about value or exemption records, and the collector about payments and balances.
If the appraisal notice appears incorrect, use MCAD’s protest instructions and your notice’s deadline. Save the property account, factual corrections and supporting evidence. A request for a tax-bill explanation does not file a valuation protest, and an appraisal appeal is not a way to replace a district’s adopted rate.
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.
- Texas Comptroller: Montgomery directory — Verified appraisal district and collector links, contacts, active units and collection coverage.
- MCAD property portal — Local appraisal records and application/protest resources; parcel-specific values must be checked by the reader.
- Texas exemption guidance — Application responsibility and unit-specific relief; no eligibility assumed.
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.
