Energy Tax Credit Income Limits: The Short Version and the Long One

The short version: the home energy credits have no income limits. None in either direction. A household earning $60,000 and one earning $2 million claim the same heat pump credit under the same caps, and nobody’s solar credit phases out at any income. The only energy credits with income tests are the vehicle ones.

People assume otherwise constantly, and the assumption costs money in a specific way: high earners skip claims they’re fully entitled to because so many other credits do phase out. The child tax credit phases out. Education credits phase out. The EV credit has hard caps. It’s a reasonable guess that energy credits work the same way. The guess is wrong.

Energy tax credit income limits by credit

CreditIncome limit?
Home improvements, 25CNone
Solar, battery, geothermal, 25DNone
EV charger, 30CNone
Clean vehicle, 30DYes: AGI caps, indexed
Used clean vehicle, 25EYes: lower AGI caps
Builder credit, 45LNone

One nuance runs the other direction. Since 2025 there’s a bonus for lower-income areas rather than a penalty for high earners: solar installed in certain low-income census tracts earns 40% instead of 30% under the OBBB rules. Income limits, no. Income bonus, in the right location, yes.

EV tax credit income limits (30D and 25E)

The 30D new-vehicle credit uses modified AGI caps that began at $150,000 single and $300,000 joint, with OBBB indexing them for inflation from 2025, a rise of roughly 3% to 4% per year. The used-EV credit runs lower, $75,000 and $150,000 at the original levels.

Two mechanics soften the caps. You qualify using either the current year’s income or the prior year’s, whichever is lower, so a raise or a windfall doesn’t retroactively kill a purchase you made in a leaner year. And the point-of-sale transfer option, where the dealer takes the credit off the price, still requires you to meet the income test, with clawback at filing if you didn’t. A dealer applying the discount is trusting your attestation, and the IRS reconciles later.

The real limit: tax liability, not income

For the home credits, the practical ceiling has nothing to do with income and everything to do with tax liability. These credits are nonrefundable. They can only offset tax you owe, so the number that gates your claim is line 22 of your 1040, and the households that hit this wall are usually lower-income filers and retirees rather than high earners.

The irony deserves a sentence. The energy credits are, mechanically, easier to use the more you earn, since a bigger tax bill absorbs a bigger credit in one year. The refundability guide covers the planning moves when your liability runs small, and the difference between the 25C credit that evaporates and the 25D credit that carries forward.

Frequently asked questions

I earn over $500k. Can I really claim the full solar credit?

Yes. Full 30%, no phase-out, no AMT trap for this credit. Claim it on Form 5695 like anyone else.

Does the credit count as income or affect my bracket?

No. A credit reduces tax after the bracket math is done. It doesn’t appear in AGI, doesn’t push you into IRMAA territory for Medicare premiums, and doesn’t affect anything else keyed to income.

My income is too high for the EV credit. Does the charger credit care?

No. The 30C charger credit has no income test, so plenty of households that miss the vehicle credit still claim 30% on the charger install, smart-charger bonus included.

We’re retired with $28,000 of income. What’s our real limit?

Whatever your tax liability is, likely a modest number at that income. The rental and second-home rules and the 25D carryforward are your friends here: solar-type projects keep their unused credit for future years, while 25C projects should be sized to the tax you’ll actually owe.

Check the right number

Skip the income worry entirely for home projects and look up last year’s line 22 instead. That figure, run through the OBBB calculator with your project list, answers the only limiting question the home credits actually ask.
