Federal Tax Considerations

Heat pump rebates can have significant federal tax implications for both businesses and individuals in Montana. Key provisions under the Internal Revenue Code (IRC) that apply include IRC § 25C and IRC § 25D, which provide credits for energy-efficient home improvements and residential clean energy, respectively.

  • IRC § 25C Energy Efficient Home Improvement Credit: Offers a 30% tax credit on the cost of qualifying heat pumps and heat pump water heaters, with an annual cap of $2,000, separate from the $1,200 general envelope cap.
  • IRC § 25D Residential Clean Energy Credit: Provides a 30% uncapped credit for geothermal heat pumps (ground-source), encouraging the adoption of renewable energy technologies.
  • Efficiency Requirements: Equipment must meet the highest efficiency tier set by the Consortium for Energy Efficiency (CEE) or be recognized as ENERGY STAR Most Efficient to qualify for these credits.
  • Claiming the Credit: Tax credits for heat pumps are claimed using Form 5695 when filing your federal tax return.
  • State Conformity: While federal tax provisions apply, verify with a Montana CPA regarding any state-level conformity or decoupling from federal tax rules.
