Texas Property Tax Basics
- Property taxes in Texas are based on the January 1 market value of your property as determined by the county appraisal district (CAD). This is the Appraisal phase of the tax calendar.
- The CAD handles all ownership, exemption and value information on your property. Under State law, appraisal districts make all changes to property records and certifies or provides the information to tax assessor collectors.
- If you have an address correction, for example, we may provide it to the proper appraisal district as a courtesy; however, the CAD records the change and provides it to each tax office.
- Each spring, CADs issue notices of appraised value, typically in April. You have until May 15th (or 30 days after the date of the notice, whichever is later) to protest the value. This is the Equalization phase of the tax calendar.
- Local governments adopt budgets and tax rates after the appraisal roll is certified, typically in late summer. In October, we produce tax statements and mail them to property owners and mortgage companies. This is the Assessment phase of the tax calendar.
- The Collection phase of the tax calendar starts when payments are made. Property taxes are delinquent February 1 (unless January 31st falls on a weekend). Unless you are taking advantage of a payment option (split or half pay or quarter payments - meaning the total amount is divided by four), payments postmarked after January 31st incur penalties and interest.
