When Do the Energy Tax Credits Expire?

December 31, 2032 is the date that matters most. The two big residential credits run at full strength through the end of 2032, which means the honest answer to “should I hurry?” is usually no. You have years. What you might not have is the right project sequence, and the calendar details below matter far more for cap planning than for beating any cliff.

Still, the credits do end, a couple of them step down before vanishing, and one deadline inside the EV rules arrives soon. The full table, then what’s actually worth hurrying for.

Energy tax credit expiration dates, credit by credit

The 25D step-down deserves the highlight. A $30,000 solar system earns $9,000 through 2032, $7,800 in 2033, $6,600 in 2034, and nothing in 2035. Each step is a four-figure difference on the same equipment, and 2033 is closer than it feels if your roof needs replacing first.

The nearest real deadline hides inside 30D. The relaxed battery-sourcing rules that OBBB extended run through 2026, and vehicle eligibility lists are expected to shrink in 2027. If a specific EV model is on your list and qualifies today, that qualification is the perishable item. Our OBBB FAQ tracks the sourcing rules as guidance comes out.

Placed in service: the rule that decides your tax year

Placed in service. Not ordered, and for most purposes not paid for. The credit belongs to the year the equipment was installed and working, and every deadline above applies to that date.

This cuts both ways at year-end. A solar contract signed in October that doesn’t get commissioned until January belongs to the new year, which is bad news beside a rate cliff and good news beside a cap reset. Solar timelines deserve real respect here. Permitting, installation, inspection, and utility interconnection routinely stretch 2 to 5 months, so a system meant to land in a specific tax year should be under contract by early summer. Nobody wants to discover in December that the interconnection queue decided their credit year for them.

Energy credits in 2026: everything is still available

Every credit is at full strength. The current-year numbers: the 25C credit offers its $1,600 general bucket plus the $2,000 heat pump bucket, the 25D credit pays an uncapped 30%, standalone batteries qualify, the smart-charger bonus is live, and the audit credit caps at $250.

Searches for “energy credits 2026” spike every January from people worried something lapsed over the holiday. Nothing did. The next scheduled change of any kind is the EV sourcing tightening after 2026, and the next residential change is the 25D step-down after 2032.

Hurry, or don’t: a project-by-project read

Worth hurrying: an EV purchase where your model qualifies under current sourcing rules. Worth mild hurry by mid-decade: solar and geothermal, since the 30% rate has a hard step-down and installation queues lengthen every year the deadline gets closer. Everything under 25C: no cliff urgency at all, and rushing is actively counterproductive when it stuffs multiple projects under one annual cap.

The annual caps are the real clock. 25C resets every January, so a multi-project plan pays more spread across years than crammed into one. The couple doing windows, insulation, and a heat pump gains nothing from finishing by any deadline and potentially loses $1,500 by finishing it all by Thanksgiving. Cap-splitting math is in the 25C guide.

Frequently asked questions

Could Congress end these credits early?

It could, and energy credits have been extended, lapsed, and revived before. OBBB’s 2025 changes moved caps around while leaving the 2032 horizon intact, which suggests stability, and multi-year carryover positions like a big 25D claim are protected for amounts already earned. Projects you’re planning on a five-year timeline carry some legislative risk. Projects this year or next carry essentially none.

If I claim solar in 2032, does my carryover survive the credit’s step-down?

Yes. Credit earned at 30% carries forward as earned, through 2034 under current rules. The step-down applies to when equipment is placed in service, not to when carried-over credit gets used.

Do state credits follow the same calendar?

No, and several state programs run on annual funding pools that genuinely do run out mid-year, unlike the federal credits. If a state rebate is part of your project math, check its funding status before scheduling, not after.

My heat pump was installed December 30 but inspected January 5. Which year?

Facts and circumstances, but placed in service generally means ready and available for use. Operational on December 30 argues for December. If the system legally couldn’t run until inspection, January. Your installer’s commissioning paperwork settles most of these, and the Form 5695 guide covers the recordkeeping.

Plan against the caps, glance at the cliff

Sequence 25C projects across January resets, put solar on the calendar with months of slack, and check EV eligibility before the 2026 sourcing window narrows. The OBBB calculator prices your plan under this year’s rules and next year’s in one pass.
