When is the deadline to protest my property value?

In Texas, the deadline to protest property values is May 15, or 30 days after the appraisal district sends notice of the assessed value – whichever is later. The appraisal district is required to send notice if the assessed value is increased by more than $1,000 from the prior year’s value. In most cases, the deadline in Texas is May 15. If the 15th falls on a Saturday or Sunday, the deadline is the following business day.
