There are numerous important dates and deadlines during the tax year. Many, such as the January 1 assessment date, are specifically stated in the Texas Property Tax Code.
Others, such as a property owner's deadline to file a notice of protest, may depend on the date the chief appraiser performs an action (in this case, the date he mails a notice of appraised value to the property owner).
Remember: if the last day to perform an action falls on a Saturday, Sunday or a legal holiday,
January 31—This is the last day to pay taxes before delinquency. The first payment on quarter payment plans for over sixty-five and disability homestead accounts is due on or before this date.
