Home Energy §25C and Solar §25D Ended After 2025: Compliance Planning for 2025 Returns and Late Installs

Author: Gloria Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line in one breath

OBBBA (P.L. 119-21) pulled forward the end of the residential energy credits: IRC §25C (energy efficient home improvement) generally does not apply to property placed in service after December 31, 2025; §25D (residential clean energy—solar, qualifying storage, and related) does not apply to expenditures made after December 31, 2025. The IRS is clear: for §25D, paying by year-end is not enough—an expenditure is generally treated as made when original installation is completed (or, for construction/reconstruction, when the taxpayer’s original use begins). As of September 2026, the work is 2025 completion proof, invoices, Form 5695, and not budgeting 2026 projects as if the old 30% credit still applies—compliance planning, not a “install now and still get 30%” pitch.

Background

The Inflation Reduction Act had aimed to keep several residential energy credits available into about 2032. OBBBA, signed July 4, 2025, accelerated multiple energy incentives’ terminations. IRS FS-2025-05 (IR-2025-86) FAQs state that §25C is unavailable for property placed in service after Dec. 31, 2025, and §25D is unavailable for expenditures made after Dec. 31, 2025. FAQ Q7 adds that even if you paid by Dec. 31, 2025, a §25D credit generally fails if installation finishes in 2026. IRS home-energy pages likewise point to a year-end 2025 completion window.

Old vs. new

1. End date: Old (IRA)—§§25C/25D generally through ~2032. New (OBBBA)—Dec. 31, 2025 is the critical cutoff (different tests below).

2. §25C test: When the property is placed in service (typically installed and available for use). Placed in service in 2026 → generally $0.

3. §25D test: When the expenditure is treated as made—usually original installation complete; payment or contract date is not the expenditure date.

4. §25C amounts (2023–2025 framework): Generally 30% of qualifying costs; about $1,200 annual cap for most improvements plus a separate about $2,000 for qualifying heat pumps / heat-pump water heaters / biomass → illustrative yearly total up to about $3,200 (with door/window/audit sub-caps).

5. §25D amounts: Qualifying solar electric, solar water heating, battery storage meeting capacity thresholds, geothermal, etc.—generally 30%; usually no small annual dollar cap like §25C, but nonrefundable, with carryforward of unused amounts often available.

6. Form: Individuals typically use Form 5695 with Form 1040; 2025 claims need manufacturer/contractor support (including any QMID rules—confirm in that year’s instructions 待核).

7. Not the same as EV credits: §§30D/25E/45W used a Sept. 30, 2025 acquisition cutoff—different article.

8. North Carolina: The federal credit reduces federal tax only; it does not create a matching NC credit. Utility rebates and local incentives are separate from Form 5695 (new state incentives 待核).

Self-check: does this affect you?

1. You finished windows, insulation, a heat pump, water heater, or energy audit in 2025 and will claim on Form 5695 for 2025.

2. You paid or contracted for solar/battery by late 2025, but completed or interconnected in 2026.

3. A contractor said a deposit “locks in” a 2025 credit—you need the IRS installation-completion rule.

4. You are pricing a 2026 solar or heat-pump job as if a federal 30% credit still applies.

5. The home has rental, vacation, or partial business use—allocation rules 待核 on the facts.

Simplified examples (illustration only; ignores state tax, credit limits, qualification, nonrefundability)

Example A — may still be a 2025 §25C claim: Cary homeowner places a qualifying heat pump in service in November 2025. Illustration: placed-in-service date is in 2025 → may claim under the 2025 §25C framework (amount depends on sub-caps).

Example B — §25D generally fails: Same neighborhood rooftop solar; full payment Dec. 20, 2025, but install and interconnection finish Jan. 15, 2026. Illustration: IRS treats the expenditure as made at installation complete → no §25D even if the invoice is dated 2025.

Example C — budget error: Spring 2026 battery install marketed with “30% federal credit.” Illustration: expenditure after the cutoff → federal §25D generally $0; look instead at any non-tax utility offers (verify separately).

Action timeline

1. Now: Gather 2025 contracts, payments, and completion / placed-in-service proof; for solar, mark whether completion/interconnection was on/before Dec. 31, 2025.

2. Open 2025 returns: Classify §25C vs §25D on Form 5695; do not mix 2026 completions into a 2025 credit.

3. Already filed, missed credit: Weigh an amendment only after invoices and qualification docs are complete.

4. 2026 projects: Price without federal §§25C/25D; separately check Duke or local rebates (待核).

5. With contractors: Get written completion dates, model numbers, and manufacturer data—avoid oral “guaranteed credit” promises.

What YCL can do

1. Review completion and placed-in-service evidence for whether a 2025 §25C / §25D claim still fits.

2. Organize Form 5695 categories, sub-caps, and nonrefundable/carryforward mechanics.

3. Flag the “paid in 2025, finished in 2026” trap and document the filing position.

4. Reset expectations for 2026 projects (no federal credit) and scan NC/utility add-ons (待核).

5. Bilingual help from Cary (RTP) and Shanghai with CPA Chenchen Liu and Gloria—compliance planning.

FAQ

Q: I paid for solar in full in 2025 but finished in 2026—can I still take §25D?

A: Under the IRS FAQ, a §25D expenditure is generally made when original installation is completed. A 2026 completion usually means no credit. Payment date alone is not enough.

Q: Can I use both §25C and §25D in the same year?

A: Yes, for separate qualifying projects under each section, subject to each credit’s limits and nonrefundability. Do not double-count the same dollars.

Q: Will North Carolina match the federal credit?

A: The federal home-energy credit does not automatically create an NC income-tax credit. Any state or utility benefit must be verified on its own—待核.
