Inflation Reduction Act brings new tax credits and rebates to incentivize energy efficiency

THE INFLATION REDUCTION ACT (IRA) is federal legislation that was enacted in August 2022 to incentivize energy efficiency and the use of efficient electric appliances and vehicles. To do this, it expanded federal tax credits and established funds for rebates. The tax credit portion of the law went into effect January 1, 2023. The rebate portion of the law is expected to roll out in late 2023 or early 2024. It will include 50–100% rebates of electrification project costs for low to moderate income households, and the discounts will be offered at the point-of-sale. Applicable projects will include qualifying heat pumps, heat pump hot water heaters, induction stoves, heat pump clothes dryers, breaker boxes and electrical wiring, insulation, air sealing and ventilation In Maine, the rebates will be administered by Efficiency Maine.

Here is a summary of currently available federal tax credits:

Heat pumps 30% up to $2,000/year
Heat pump water heaters 30% up to $2,000/year
Insulation and air sealing 30% up to $1,200/year
200+ amp circuit panels 30% up to $600/year
Energy audits 30% up to $150/year
Wood / pellet stove / boilers 30% up to $2,000/year
Geothermal 30% no cap
Electric vehicle tax credits (EVs) up to $7,500 for new vehicles and up to $4,000 for
used vehicles (restrictions apply).
EV charging equipment 30% up to distinct caps for residential vs. commercial

Notes: A taxpayer may not claim a credit of more than $2,000 for total expenditures on heat pumps, heat pump water heaters, and biomass stoves and boilers in any single year. For other upgrades (excluding geothermal and EVs) listed above, an aggregate annual tax credit cap of $1,200 applies. The credit covers purchase and installation costs for heat pumps, heat pump water heaters and panel upgrades; it only covers purchase costs for other listed upgrades.

In addition to the federal tax credits noted above, Efficiency Maine offers rebates on some project costs.

Heat pumps $4,000 to $8,000
Heat pump water heaters up to $1,050*
Insulation up to $8,000
Electric vehicles (EVs) $2,000 to $7,500 (for individuals)

Inflation Reduction Act FAQs

Can I combine the tax credits with Efficiency Maine’s current energy efficiency rebates?
Yes

Who qualifies for the tax credits?
Anyone with adequate tax liability to offset can qualify. The improvements must be made to your main home, located in the US, and it must be an existing home and not a new home.

If my tax liability is less than the credit, can I apply the excess credit to a future tax year?
No. You can’t apply any excess credit to future tax years. The credit is nonrefundable, so you also can’t get back more on the credit than you owe in taxes.

Do any of the tax credits or rebates apply to renters?
Yes, renters may qualify for rebates for portable appliances like window-unit heat pumps and induction cooktops, and tax credits for qualifying portable, window-unit heat pumps (requirements for the latter expected by 2024).

Is there a maximum credit I can claim each year?
Yes, the annual aggregate maximum for heat pumps and heat pump water heaters is $2,000. The annual aggregate maximum for insulation, doors, windows, electrical panel upgrades and energy audits is $1,200. These limits reset every year. So, if you spread out your upgrades, you can take advantage of the credit for multiple years. You can claim the credit for improvements made through 2032, and there is no lifetime limit.

Do all heat pumps, electric appliances and electric vehicles qualify?
No. Products must meet stated efficiency standards, and in the case of electric vehicles, the amount of the credit corresponds to income level, where the vehicle was assembled and battery components and/or critical mineral sourcing. Learn more here: fueleconomy.gov/feg/tax2023.shtml
