Federal Solar Tax Credit in 2026 — It Expired for Purchased Systems

Here's the headline that catches most Las Vegas homeowners off guard in 2026: the 30% federal solar tax credit (the Residential Clean Energy Credit / Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act. If you buy a system this year — cash or loan — there's no federal credit to claim. It survives only for lease and PPA systems through end of 2027, where the third-party owner captures it. The good news is Nevada's own incentives didn't change, and rising NV Energy rates make solar a stronger hedge than ever.

What changed and when

For years, homeowners who bought solar could claim 30% of the installed cost as a dollar-for-dollar reduction in their federal income tax. That credit had a hard cutoff: systems had to be placed in service by December 31, 2025. Buy and install in 2026 and there's no Section 25D credit. Background and the historical rules are on the IRS Residential Clean Energy Credit page — but for a 2026 cash or loan purchase, the answer is simply zero.

The one exception: lease and PPA

Third-party-owned systems — leases and power purchase agreements — can still capture a federal incentive through the end of 2027. The catch: the company that owns the panels on your roof claims it, not you. They may pass some value through as a slightly lower monthly rate, but you don't get a check and you don't own the asset. For most Vegas homeowners, ownership still wins on total dollars even without a federal credit.

What still pays in Nevada

With the federal credit gone for purchases, these are the incentives that actually move your number now:

• Nevada sales-tax exemption: solar equipment is exempt from Nevada sales tax (~8.375% in Clark County), applied at purchase. On a $24,000 system that's real money off the top.
• Nevada property-tax exemption: your home isn't reassessed for the value solar adds (NRS 361.079). You get the resale bump without a higher annual tax bill.
• NV Energy net metering: exported solar is credited at 75% of retail, locked for 20 years.
• The rate hedge: NV Energy rates rose ~9.5% in the past year to about 17.45¢/kWh. Every increase makes your self-generated power more valuable. You're locking in your own generation cost against a utility that raises rates every couple of years.

Sales-tax-exemption reference: NRS 374.

What the credit's expiration means for your quote

The biggest practical risk in 2026 is an old quote or an out-of-state rep still shaving 30% off the price as if the credit were live. It isn't. A 2026 cash price is the sticker price after Nevada's sales-tax exemption — roughly $2.85/watt, so about $17,100 for 6 kW, $19,950 for 7 kW, or $22,800 for 8 kW. Don't let anyone bake a phantom federal credit into your payback math.

Payback now

Cash payback in Las Vegas runs roughly 9–12 years for a cash purchase now that the 30% federal credit has ended — though NV Energy's rising rates keep pulling that number down. After payback, you're into 15+ years of essentially free electricity under the panels' warranty.

California neighbors — same federal change, different state incentives

If you own across the border, the federal 30% credit also expired December 31, 2025 for owned systems. But California's SGIP battery rebate and NEM 3.0 rules are unchanged — see SGIP Battery Rebate California. The federal piece is gone there too; the state programs still pay.

Do I still need a CPA?

For a 2026 purchase, there's no federal solar credit to file, so there's no Form 5695 step for the panels. Nevada's exemptions are applied at purchase and on your property assessment — your installer handles the sales-tax exemption, and the property-tax exemption is automatic. If you're on a lease/PPA or have a complex situation, a quick CPA check is still cheap insurance.
