Energy Conservation Devices Tax Credit

Baltimore County Code, 11-2-203.3

 The Energy Conservation Device tax credit offers assistance to residential or multi-family residential property owners who utilize solar or geothermal energy devices.

  • Eligible solar devices include those that heat, cool, provide hot water or generate electricity in a structure.
  • Eligible geothermal energy devices include those that heat or cool a structure or provide hot water for use in a structure. Geothermal devices do not generate electricity.

This credit applies only to your Baltimore County Real Property Tax obligation. Any other charges listed on your bill are not included as part of the credit calculation.

Waiting List in Effect

There is an annual budgetary limitation for this credit of $250,000. As a result of this limitation and the large number of applications received, a waiting list was established. Applications are placed on the list in the order received and are scheduled to be awarded on the July 1, 2024 property tax bill. Placement on the waiting list assures that the applicant will receive the credit in accordance with the Baltimore County Code on the earliest possible date.

Amount of the Credit

The amount of the tax credit allowed under this section of the law is 50 percent of the eligible cost of the device, or $5,000 for a heating or cooling system or $1,500 for a hot water supply system, whichever is less.

A credit claimed during a tax year may not exceed the amount of the property taxes owed during that year, and the excess amount may be carried forward for up to two additional tax years.

Eligible costs are those payments made by the property owner within the 12 months before the initial application and include all parts, components or accessory equipment necessary to operate the device as well as reasonable costs associated with the installation of the device.

Transfer of Ownership

The credit does not run with the property and a change of ownership will cause the credit to terminate.

Apply for the Tax Credit
