Collin County residents have at least until May 15 to file property appraisal protests with the Collin Central Appraisal District. Filing a protest initiates a review process to determine whether the property appraisal value was appropriate. The passage of House Bill 2228 during the 2017 Texas Legislature moved the property tax protest filing deadline up approximately two weeks but kept the minimum protest period of 30 days. Due to HB 2228, the deadline to protest this year was moved from May 31 to May 15, or 30 days after the delivery of the notice of appraised value, whichever is later. Most homeowners can file protests on the Collin Central Appraisal District’s website at www.collincad.org. Collin County residents who are not willing or able to file online can also obtain protest forms at their appraisal district headquarters, located at 250 Eldorado Parkway in McKinney.
