At The Ray Tax Group we offer our simple easy to use online signup feature. It is the easiest way to look up your address and reduce your property tax for a flat fee. Currently our automated online signup feature only fully supports Tarrant, Denton, Collin, Travis, Harris, and Dallas counties. If you have property in another county or it just won't pull up for some reason you can still sign up online and it will just take about 3 minutes instead of 2. You can sign up here if you have a property in an unsupported county or one that just won't pull up.
