The Texas Constitution requires the Tax Assessor-Collector office for counties with more than 10,000 in population.

Effective January 1, 1982, state law required counties participate in a single appraisal district. Under this revision, the duty of apprasing property for value and exemption use became the duties of the office of the chief appraiser of the appraisal districts.

The Montgomery Central Appraisal Distict identifies property to be taxed, determines its appraised value, whether to grant exemptions, the taxable owner and address, and which taxing jurisdictions may tax the property.

The Montgomery County Tax Office receives the certified tax roll from the Montgomery Central Appraisal District, usually in July, then the property values are loaded on the Tax Office Computer System. The certified tax roll and the tax rates adopted by each taxing jurisdiction are used to levy the current property taxes in October of each year. Tax statements are then generated and mailed to property owners and/or mortgage companies using a consolidated tax bill.

The Montgomery County Tax Office requires mortgage companies request their clients tax statement each year. Request are due by mid-August and failure to request in a timely matter may result in the clients (property owners) receiving their tax statement directly. Property owners are required to ensure the information on their tax statements is correct and any errors should be directed to the Montgomery Central Appraisal District immediately.
