If you’ve been scrolling through energy blogs or chatting with that one neighbor who’s obsessed with his electric bill, you’ve probably heard a dozen different dates for the "death" of the solar tax credit. Some say 2032. Others say it’s already gone.
The truth? It’s a bit of a mess right now.
Honestly, the landscape shifted dramatically this past year. For a long time, we were looking at a steady 30% credit through the early 2030s thanks to the Inflation Reduction Act. But politics happened. With the signing of the One Big Beautiful Bill (OBBB) on July 4, 2025, the timeline for the residential solar tax credit—specifically the one homeowners claim themselves—was chopped down.
When Does the Solar Tax Credit End for Homeowners?
The hard deadline for the residential portion (Section 25D) was December 31, 2025.
If you are reading this in 2026 and you just bought solar panels out of pocket or with a standard solar loan, you likely missed the boat for the federal credit. To qualify, the system had to be "placed in service" by the end of 2025. In IRS-speak, that means the panels weren't just sitting in your driveway; they had to be fully installed and ready to pump out power.
It's a tough pill to swallow for anyone who waited. We saw a massive "mad rush" in late 2025, with installers working double shifts just to beat the clock.
But here is where it gets interesting: the credit didn't die for everyone.

The Loophole: Third-Party Ownership
While the 25D credit for homeowners who own their systems is gone, the 48E Clean Electricity Investment Credit is still alive and kicking. This is the credit claimed by businesses.
If you choose a solar lease or a Power Purchase Agreement (PPA) in 2026, you can still benefit indirectly. The company that owns the panels on your roof claims the 30% credit and, ideally, passes those savings to you through a lower monthly payment. This "third-party owned" model is basically the only way to tap into federal solar incentives right now.
This corporate-level credit is currently slated to last through the end of 2027.
The Commercial Side: A Different Set of Rules
For business owners, the "when does the solar tax credit end" question has a much more nuanced answer. You aren't facing a total blackout just yet, but the clock is ticking on the "safe harbor" rules.
Commercial projects that begin construction by July 4, 2026, can still lock in that sweet 30% rate.
What does "beginning construction" actually mean? You can’t just sign a piece of paper and call it a day. The IRS generally looks for two things:

- Physical Work: Real, significant work starting on-site or off-site (like custom-built racking).
- The 5% Rule: Spending at least 5% of the total project cost.
If a business starts a project by that July 2026 cutoff, they typically have about four years to actually finish the installation and still grab the credit. If they miss the "start" date, they have to have the system fully operational by December 31, 2027, to get anything at all.
Sourcing Worries (The FEOC Factor)
There is a catch that most people aren't talking about yet. Starting January 1, 2026, new rules regarding Foreign Entities of Concern (FEOC) kicked in.
Basically, if your solar panels or battery components are sourced from certain countries—think China or Russia—it could complicate or even disqualify the tax credit. This is making procurement a total headache for installers this year. Even though the credit is technically available for businesses, finding "compliant" equipment is getting more expensive and difficult.
Does This Make Solar a Bad Deal in 2026?
You'd think that losing a 30% discount would kill the industry, right? Surprisingly, it hasn't.
Prices for solar hardware—panels, inverters, and racking—have continued to slide. At the same time, utility rates in places like Pennsylvania, California, and Iowa have been jumping way faster than general inflation.
I was talking to a developer recently who pointed out that the "payback period" for a system in 2026 (without the credit) is actually similar to what it was in 2019 (with the credit). The math still works because the grid is getting so much more expensive.

Plus, many states have stepped up. Local incentives, like SRECs (Solar Renewable Energy Certificates) in New Jersey or Maryland, can still shave thousands off the long-term cost.
Actionable Steps for 2026
If you're looking at your roof and wondering if you should still pull the trigger, here is the "no-fluff" reality:
- Check Local Rebates: Federal money might be dry for homeowners, but your state or local utility might still have a "pot" of money waiting. Don't assume the federal expiration means $0 in help.
- Run the PPA Math: If you want that 30% benefit, look into a lease or PPA. Just be sure to read the fine print on the "escalator clause" (how much your payment goes up every year).
- Batteries are Different: Standalone battery storage is still in a bit of a grey area under the new laws. If you're adding storage to an existing system, consult a tax pro—don't just take the salesperson's word for it.
- Commercial Urgency: If you own a business, you have until July 4th to "start construction" to safe-harbor your 30%. Waiting until the fall of 2026 could be a very expensive mistake.
The era of easy, universal 30% checks from the IRS is over for the average homeowner. We’re in a new phase now where you have to be a bit more strategic—and maybe a bit more skeptical—to make the numbers move in your favor.
Focus on the "avoided cost" of your rising utility bill rather than just chasing a tax credit that might not be there when you file. That is where the real long-term wealth is built anyway.
To move forward with your project, start by requesting a current quote that specifically breaks down the "equipment origin" to ensure any commercial or lease credits aren't jeopardized by the new 2026 FEOC sourcing rules. Once you have that, verify with a tax professional whether your specific financing structure qualifies under the 48E corporate credit umbrella.
