OBBBA Tax Credit Deadline Tracker

Multiple federal tax credit deadlines have passed: Section 30D (EV) expired September 30, 2025, Section 30C (charger) expired June 30, 2026, and the Section 48E construction-start deadline passed July 4, 2026. Countdown to the December 31, 2027 phase-out remains active for projects that began construction in time.

Data verified June 2026 — see our tax credit accuracy standards.

Section 30D (EV Tax Credit) Expired Sep 30, 2025

The federal clean vehicle tax credit ended September 30, 2025 under the OBBBA. No new EV purchases qualify for the 30D credit. Separately, the Section 30C EV charger/refueling property credit expired June 30, 2026. Both deadlines have passed.

Section 48E Construction-Start Deadline — Passed July 4, 2026

The Section 48E construction-start deadline has passed. Solar ITC eligibility required construction to begin before July 4, 2026. The 5% expenditure safe harbor was RESTORED on June 6, 2026 after a federal court vacated IRS Notice 2025-42 (Oregon Environmental Council v. IRS, No. CV-25-4400). Projects that began construction in time can still qualify with the December 31, 2027 placed-in-service deadline. Check your project status.

Multiple federal deadlines have passed (30D EV credit: Sep 30, 2025; 30C charger credit: June 30, 2026; 48E construction-start: July 4, 2026). Projects that began construction by the 48E cutoff must still be placed in service by December 31, 2027. Use the countdown calendar below to track the final phase-out deadline for qualifying projects.

Key OBBBA Deadlines & Required Actions

Three statutory deadlines define the OBBBA timeline. Here's exactly what each one is and what to do now.

Ended Sep 30

Section 30D — EV Tax Credit

The federal clean vehicle (EV) tax credit of up to $7,500 ended September 30, 2025. New EV purchases after that date no longer qualify for the 30D credit.

Action to take

  • If you purchased/leased a qualifying EV on or before September 30, 2025 and placed it in service, keep your purchase and FEOC/assembly documentation to claim the 30D credit
  • Verify the vehicle and manufacturer meet FEOC and assembly requirements
  • Confirm your modified AGI is under the eligibility limits
Check EV credit eligibility
Passed July 6

Section 48E — Construction-Start

Solar ITC eligibility required that construction begin before July 4, 2026 under the Physical Work Test or the restored 5% Safe Harbor. This was the last chance to lock in the 30% federal credit for leases, PPAs, commercial, and rental properties.

What to know

  • If you signed a binding written contract and began physical work before July 4, 2026, you may still qualify — keep all contracts, progress invoices, and FEOC certifications on file
  • Projects must be placed in service by December 31, 2027
  • If you did not begin construction by the deadline, the federal ITC is no longer available for your project
Compare financing & passthrough options

With multiple deadlines passed: The countdowns above now show "Deadline Passed" for 30D, 30C, and 48E. Projects that began construction before the 48E cutoff can still qualify through state incentives and must be placed in service by December 31, 2027 to preserve federal eligibility. New projects starting after July 4, 2026 have no federal ITC path.

Post-OBBBA Shift

Post-OBBBA market shift: the financing inversion

The 25D expiry and 48E survival didn't just change the deadline math — they flipped which financing structure wins. Source: SEIA Q1 2026 US Solar Market Insight.

Q1 2026 residential growth

+6%

1,179 MWdc · 100% TPO-funded

Cash-buyer market

-28%

Enphase revenue YoY — segment contracted

CA lease vs cash payback

$0.18–$0.22/kWh

vs ~14 yr cash payback

Section 25D expired January 1, 2026, but Section 48E survived under the OBBBA — only Third-Party Ownership providers (leases and PPAs) can monetize it. Q1 2026’s +6% growth was therefore entirely TPO-funded, while the cash-buyer segment contracted (Enphase -28% YoY). The result is an effective-rate inversion: in California, lease/PPA now lands at $0.18–$0.22/kWh against a cash-payback horizon of ~14 years — 48e tax credit passthrough to lease/ppa customers.

Estimates use data from Treasury FEOC guidance, DSIRE state incentive database, and NREL average cost data. The federal Section 25D residential solar credit expired December 31, 2025. The Section 30D EV credit ended September 30, 2025 (the Section 30C EV charger credit expired June 30, 2026). Section 48E ITC required construction to begin before July 4, 2026 and placed in service by December 31, 2027; the 5% safe harbor was restored by Oregon Environmental Council v. IRS (No. CV-25-4400, June 6, 2026) — the IRS may appeal. Countdowns target 11:59 PM Eastern Time on each deadline date.
