Quotes That Subtract the 30% Federal Tax Credit in 2026

What you might hear
You'll get 30% back from the federal government, so your real cost is only $16,800 instead of $24,000.

What's actually true

The Section 25D homeowner credit does not apply to systems whose installation was completed after December 31, 2025. If you buy with cash or a loan in 2026, your federal credit is $0.

If you are buying solar with cash or a loan and your installation finishes in 2026, you get no federal tax credit. The 30% residential clean energy credit (Section 25D) ended for any system whose installation was completed after December 31, 2025. A quote that still subtracts 30% is either out of date or misleading, and it makes solar look about 30% cheaper than it is.

What the law actually says

Congress ended Section 25D in the July 2025 budget law (P.L. 119-21). The statute says the credit does not apply to expenditures made after December 31, 2025. An expenditure counts as “made” when installation is completed, not when you sign or pay. The IRS confirmed this in its August 2025 FAQ: paying in 2025 is not enough if installation finished in 2026.

There was no phase-down. It went from 30% straight to 0%. A Senate bill (S. 3722) would extend it, but as of October 2026 it had no committee or floor action. Don’t buy based on a bill that hasn’t passed.

The one exception that confuses people

Leases and PPAs are different. The company that owns a leased system can still claim a separate business credit (Section 48E) if deadlines and sourcing rules are met. That credit goes to the company, not to you. You benefit only if the company passes it through as a lower price. A rep who says “you still get the 30%” on a lease is wrong about who gets it. See lease vs. buy vs. PPA.

A worked example

An 8 kW system priced at $3.00 per watt costs $24,000.

Gross price$24,000$24,000
Federal tax credit-$7,200$0
Net cost$16,800$24,000
Payback at $1,800/yr savingsabout 9.3 yearsabout 13.3 years

That four-year gap can turn a good deal into a marginal one. It also matters for loans: many solar loans were built to expect a lump-sum paydown equal to the credit. If you never get the credit, your payment can jump. See reamortization balloons.

How it shows up in a quote or contract

  • “Net investment,” “cost after incentives” or “effective cost” lines
  • A savings chart with a big bump in year one or two
  • Loan terms with a “voluntary prepayment” or “ITC paydown” in month 12 to 18
  • Fine print saying “consult your tax advisor” next to a credit the rep just promised you

Questions to ask

  • “Does any number in this proposal include a federal tax credit? Which line?”
  • “Please send a version with the federal credit set to zero.”
  • “Is this loan’s payment based on me paying down part of the balance early? What happens if I don’t?”
  • “If this is a lease, does my price depend on the company getting the 48E credit?”

What to do next

Run your quote through the sales claim checker and redo the payback in the payback calculator with no federal credit. Our guide to whether solar is worth it in 2026 shows when it still pays without the credit. Some state and utility incentives do remain; check incentives.

Bottom line: For an owned system installed in 2026, the federal credit line should read $0. If it doesn’t, ask why in writing.
