If your property in Texas has been overvalued, this Texas property tax protest guide can help you take action and lower your tax bill. Start by reviewing your appraisal notice from your local appraisal district and compare the assessed value to similar properties in your area. If the value seems inflated, gather supporting evidence—such as recent sales, photos, or repair estimates—and file a protest within 30 days of receiving your notice. Once filed, you may present your case to the Appraisal Review Board (ARB). A successful Texas property tax protest can lead to a reduced valuation and significant savings on your annual property taxes.
