The honest answer is: mostly not, and the reason is worth understanding rather than skipping past. “Tax deductible” and “tax credit” get used interchangeably in everyday conversation, but they’re two different mechanisms that produce different savings — and for solar specifically, getting the terminology right changes what you should actually expect on your tax return.
A Credit and a Deduction Are Not the Same Thing
A tax deduction reduces your taxable income before your tax bill is calculated — its value depends on your tax rate, so a deduction is worth more to someone in a higher bracket than someone in a lower one. A tax credit, by contrast, reduces the tax you owe dollar for dollar, regardless of your tax bracket, which generally makes a credit more valuable than a deduction of the same nominal size.
The federal incentive most people are thinking of when they ask whether solar panels are “tax deductible” was actually a tax credit, not a deduction — which matters because the two behave very differently if your tax situation is unusual, and because only one of them ever technically applied to a homeowner’s system in the first place.
What Actually Applies to a Homeowner’s System in 2026
For a homeowner who purchases a system with cash or a loan, there was never a federal deduction — the Residential Clean Energy Credit under Section 25D of the tax code was a credit, reducing your federal tax liability by 30% of qualifying costs. That credit ended for any system installed after December 31, 2025. For a homeowner purchasing a system in 2026, there’s neither a federal deduction nor a federal credit available — the tax mechanism most people associate with “going solar” simply isn’t part of the calculation anymore for a purchased residential system.
What’s still real: California’s property tax exclusion (which prevents your home’s assessed value from increasing because of the system) and the Self-Generation Incentive Program’s battery rebates. Neither of these is a federal tax deduction or credit — they’re state-level programs that work differently, and we’ve covered what’s actually available in more detail in a separate post on California solar incentives.
What Actually Applies to a Business’s System
For a business, the picture includes an actual deduction, which is where the “tax deductible” framing gets closer to accurate — just not for the reason most people assume. A commercial solar system still qualifies for the 30% Investment Tax Credit under Section 48E, which is a credit, not a deduction. But a business can also depreciate the system’s cost as a business asset, and the IRS confirmed permanent 100% bonus depreciation for qualifying property acquired after January 19, 2025 — meaning a business can generally deduct the depreciable cost of the system in the year it’s placed in service.
So for a commercial system, both mechanisms genuinely apply: a credit (the 30% ITC) and a deduction (depreciation), stacked together. That combination is real and can meaningfully reduce a business’s effective cost, but it only applies to a business claiming the system as a depreciable asset — not to a homeowner’s personal residence, which isn’t a business asset and was never eligible for a depreciation deduction in the first place.
Why the Distinction Matters for Your Numbers
If you’re a homeowner and you’ve heard “solar is tax deductible,” the useful correction isn’t just semantic — it changes what to expect on your return. There’s no deduction to itemize and, as of 2026, no credit either for a purchased system. If you’re a business owner, the useful correction runs the other way: you’re not just getting “a deduction,” you’re potentially getting a credit and a deduction together, which is a stronger outcome than either term alone suggests.
Either way, the specific numbers depend on your situation — your tax liability, whether you’re buying or leasing, and whether the system is personal or a business asset. A CPA who’s looked at your actual return is the right person to confirm exactly what applies; we’re glad to walk through the mechanics as they relate to your specific system in the meantime.

Frequently Asked Questions
Is there any tax credit for solar panels in 2026? For a homeowner buying a system, no. For a business, yes — the 30% Investment Tax Credit under Section 48E is still available.
Can I deduct solar panels on my personal residence? No. A personal home isn’t a depreciable business asset, so there was never a deduction available for a homeowner’s own system in the first place.
Does my business get a credit and a deduction, or just one? Both, if the system qualifies as a business asset — the 30% ITC and 100% bonus depreciation can stack together.
What’s the simplest way to remember the difference? A deduction lowers the income you’re taxed on; a credit lowers the tax bill itself, dollar for dollar. A credit is generally worth more for the same nominal amount.
