Your application paperwork

Form to file: Form 50-123 (Exemption Application for Solar or Wind-Powered Energy Devices)

Texas exempts the added value that a solar or wind energy device gives your property from property tax, so installing solar or wind does not raise your tax bill. You file Texas Comptroller Form 50-123 once with your local county appraisal district. (Texas law also protects a homeowner's right to install solar.)

  1. Confirm you own the property and have installed (or will install) a solar or wind energy device for on-site use.
  2. Download Form 50-123, Exemption Application for Solar or Wind-Powered Energy Devices, from the Texas Comptroller.
  3. Complete the form with the property and device information.
  4. File it with your local county appraisal district (not the Comptroller), generally by April 30.
