Inflation Reduction Act · 25C $2K · 25D 30% · 30D EV · Stacks With Mass Save

Federal Tax Credits 25C, 25D, 30D.

The Inflation Reduction Act federal tax credits stack with Mass Save rebates and the 0% HEAT Loan. 25C up to $2,000 for heat pumps, 25D at 30% of geothermal/solar cost, 30D EV credit. Filed via IRS Form 5695.

What the IRA Credits Actually Are

The Inflation Reduction Act of 2022 created and expanded three federal tax credits relevant to Massachusetts homeowners. All three are non-refundable tax credits — meaning they reduce your federal tax liability dollar-for-dollar, but cannot reduce your liability below zero. They are claimed on your federal tax return (IRS Form 5695 for 25C/25D, Form 8936 for 30D) for the year the qualifying installation was placed in service.

These credits are federal. They stack with Massachusetts state-level Mass Save rebates and the Mass Save HEAT Loan with no interaction.

25C: Energy Efficient Home Improvement Credit

Annual federal tax credit up to $3,200 for residential energy efficiency improvements. Sub-caps:

  • $2,000 for qualifying heat pumps and heat pump water heaters (cold-climate certified ASHP, ductless mini-split heat pumps, geothermal heat pumps qualify under 25D not 25C).
  • $1,200 aggregate for insulation, air sealing, exterior doors ($250/door, $500 total), windows ($600 total), and home energy audits ($150).
  • $600 for electrical panel upgrades that enable a 25C-qualifying upgrade.

The credit is 30% of cost up to the sub-cap. So a $7,000 heat pump install qualifies for the full $2,000 since 30% of $7,000 is $2,100, capped at $2,000. The credit is annual — it resets each year, so you can spread upgrades across years to maximize.

25D: Residential Clean Energy Credit

30% of the total installed cost of qualifying clean energy systems, with no annual cap. Eligible:

  • Solar photovoltaic (PV) systems
  • Solar water heating systems
  • Geothermal heat pumps (ground-source)
  • Battery storage systems with capacity ≥ 3 kWh
  • Small wind energy systems
  • Fuel cell systems (specific limits)

Geothermal is the big one for Massachusetts homeowners — a $35,000 ground-source heat pump install qualifies for a $10,500 federal credit, on top of the Mass Save rebate of $15,000+.

25D is not capped annually. If your tax liability is less than 30% of the install cost, the unused portion carries forward to future tax years.

30D: New Clean Vehicle Credit (EV Credit)

Up to $7,500 federal tax credit for qualifying new electric vehicles. Split: $3,750 for sourcing-of-critical-minerals, $3,750 for battery-component sourcing. The vehicle must:

  • Be assembled in North America
  • Have an MSRP under $80,000 (SUVs/trucks/vans) or $55,000 (sedans)
  • Buyer's adjusted gross income under $300K (joint), $225K (head), or $150K (single)

Massachusetts homeowners installing a Level 2 EV charger should pair the 30D credit with the MOR-EV rebate (Massachusetts Department of Energy Resources rebate up to $3,500) and the Mass Save EV charger rebate ($700+). Eligibility on each program is independent.

How to Claim These Credits

  1. Keep all receipts and the manufacturer certification statement. Pro Build provides both as part of the project closeout package.
  2. Confirm the equipment is on the federal-eligible list. 25C heat pumps must meet specific HSPF/SEER thresholds. 25D systems must meet ENERGY STAR or applicable certification.
  3. File IRS Form 5695 with your federal tax return for 25C and 25D. File IRS Form 8936 for 30D.
  4. Claim in the year the system was placed in service — generally the year of installation, not the year of purchase.
  5. Keep records for at least 3 years in case of IRS audit.

Federal Resource FAQs

Massachusetts Federal Resource Questions Answered.

Are these credits refundable?

No. All three (25C, 25D, 30D) are non-refundable tax credits — they reduce your tax liability but cannot result in a refund larger than your tax bill. 25D unused portions carry forward to future tax years; 25C and 30D do not carry forward.

Do federal credits affect my Mass Save rebate?

No. The two are completely independent. Mass Save is a Massachusetts utility-funded program. Federal credits are claimed on your federal tax return. They stack on the same project with no reduction.

Can I claim 25C every year?

Yes. 25C resets annually. Many Massachusetts homeowners spread upgrades across years (e.g., insulation in year 1, heat pump in year 2, panel upgrade in year 3) to claim the credit each year.

Is the EV charger eligible for 25C?

Yes — under the Alternative Fuel Vehicle Refueling Property Credit (separate provision, not 25C/25D). The credit is 30% of the cost, capped at $1,000 per residential charger. Filed on IRS Form 8911.

What if my tax liability is less than the credit?

25D unused portions carry forward to future tax years. 25C and 30D do not carry forward — if your tax bill is too low, the unused portion is lost. Plan with your tax preparer.

Does Pro Build help me file the credits?

Pro Build provides all required documentation (manufacturer certification, AHRI matched specs, installation invoices). The actual tax filing is between you and your tax preparer — we are licensed contractors, not tax professionals. Most Massachusetts CPAs are familiar with the IRA credits.

Are there income limits on 25C and 25D?

No. 25C and 25D have no income caps. Only 30D (the EV credit) has income limits ($300K joint / $225K head / $150K single).

When do the IRA credits expire?

25C runs through 2032. 25D runs through 2034. 30D runs through 2032. All are subject to congressional action — verify with your tax preparer in the filing year.
