Harris County homeowners face property tax protest deadline to lower bills

Harris County homeowners who received a late appraisal notice may still have a path to cut their tax bill, but only if the protest window on the notice has not closed. The countywide May 15 deadline passed, yet Harris County Appraisal District said some owners got their value notices after April 15 or had not received them yet, and the later deadline printed on the notice controls.

The protest is aimed at the appraised value, not the tax rate. HCAD said the notice shows what the district believes a home could sell for as of January 1 of the tax year, and Chief Appraiser Adam Bogard said homeowners typically see two figures, market value and appraised value, with the appraised value sometimes capped if the owner has a homestead exemption. HCAD does not set tax rates or collect taxes; school districts, cities and other local taxing entities later apply their rates to the value on the books.

For homeowners who still have time, the fastest filing route is HCAD’s Electronic Filing and Notice System. The district also uses Form 50-132, which can be downloaded, mailed or hand-delivered. If a protest is going out near the deadline, HCAD warns that the envelope should be manually stamped at the post office because the district uses the postmark date to judge timeliness.

The money at stake depends on the size of the overvaluation and the home’s price. A $10,000 reduction on a $200,000 home removes 5 percent of the home’s value from the tax base. On a $300,000 home, a $25,000 correction equals about 8.3 percent of value; on a $500,000 home, the same $25,000 represents 5 percent. Because the tax rate is set later by local governments, the final bill savings vary, but the underlying value reduction is what lowers the bill.

Harris County’s property tax system keeps sending thousands of homeowners back into the same fight every spring. HCAD, established in 1980, now serves more than 600 taxing units and appraises nearly 1.9 million parcels with a combined market value of about $905 billion. The district’s reminder is blunt: once the protest window closes, the value can stick for the year, and the bill follows.
