The Elephant in the Room: Tax Season 2026 and Your Solar Panels
If you’re sitting down at your kitchen table in Camas or Portland this March, sorting through receipts and getting ready to file your taxes, you might be searching for the holy grail of renewable energy incentives: The 30% Federal Solar Tax Credit. For over a decade, this credit was the main engine driving solar adoption across the Pacific Northwest. It was simple, massive, and available to almost every homeowner. But if you’ve been reading up on solar lately, you’ve probably noticed a ton of conflicting information online. Some websites say the 30% credit is alive and well, while others say it’s completely gone.
So, what is the actual truth for our neighbors in Washington and Oregon?
As your local Washougal-based solar experts, we believe in giving you the straight facts. The truth is, following the passage of the federal “One Big Beautiful Bill” (OBBB) in 2025, the solar tax landscape experienced a massive earthquake. The 30% credit still exists, but who gets to claim it has fundamentally changed.
In this comprehensive guide, we’ll explain exactly what the 30% Federal Solar Tax Credit is in 2026, why national blogs might be giving you bad advice, and how you can still secure massive savings on your PNW solar installation.
The 2026 Reality: A Tale of Two Tax Codes
To understand what happened to the 30% federal solar tax credit, we have to look at the two different sections of the U.S. tax code that govern renewable energy.
Section 25D: The Residential Credit (Expired)
This was the credit most homeowners knew and loved. Under Section 25D, if you bought a solar energy system for your primary or secondary home, you could claim 30% of the total cost as a dollar-for-dollar reduction on your federal income taxes.
The 2026 Update: As part of the OBBB Act of 2025, the residential version of this credit officially sunsetted on December 31, 2025. If you are a homeowner purchasing a system for your house in Vancouver or Beaverton today, there is no longer a federal residential tax credit.
Section 48: The Commercial Credit (Alive and Well)
This section of the tax code applies to businesses. Under Section 48, the Investment Tax Credit (ITC) allows businesses to claim 30% of the cost of a solar energy system installed on commercial property.
The 2026 Update: Unlike the residential credit, the commercial 30% ITC survived the recent legislative changes and remains fully active. If you own a business—whether it’s a manufacturing facility in Longview or an agricultural operation in Amboy—you can still claim this massive 30% credit, alongside accelerated MACRS depreciation.
Why Generic Online Advice is Dangerous Right Now
If you Google “How to get the 30% solar tax credit,” you will likely find hundreds of articles telling you it’s perfectly fine to claim it on your home. Why? Because the internet is full of outdated articles and out-of-state lead generation companies that haven’t updated their content for the 2026 tax year.
We’ve seen aggressive national sales teams knock on doors in Washougal, promising homeowners a 30% federal tax write-off just to get a signature on a contract. When tax time rolls around and the homeowner realizes the residential credit expired last year, that out-of-state salesperson is long gone.

The Good News: Commercial Solar is Still Thriving
While the residential credit has retired, the commercial solar tax credit remains a powerful financial tool for businesses in 2026. If your property is used for business purposes—such as a dedicated commercial facility, a farm, or a standalone workshop—you may still be eligible to claim the 30% Investment Tax Credit under Section 48.
This incentive is designed to help local economies transition to renewable energy efficiently. The Internal Revenue Service (IRS) provides specific, updated guidance on how businesses can leverage this credit alongside accelerated depreciation to maximize their return on investment. You can also explore theDatabase of State Incentives for Renewables & Efficiency (DSIRE) to see how this federal commercial credit stacks with local PNW business grants.
The 2026 Silver Lining: Local Incentives Reign Supreme
The expiration of the residential federal tax credit sounds like bad news, but for residents of the Pacific Northwest, the sky isn’t falling. In fact, Washington and Oregon have some of the most robust local solar programs in the entire country. Because utility rates have continued to climb, these local incentives make solar ownership highly profitable in 2026.
For Our Washington Neighbors
If you live in Clark County, Cowlitz County, or anywhere north of the Columbia River, your ROI is driven by the state’s incredible commitment to clean energy.
- The 100% Sales Tax Exemption: Washington State still exempts solar energy systems (under 100kW) from the state sales tax. In cities where sales tax pushes 9%, this is an immediate, upfront discount that rivals the old federal credit—and requires zero tax paperwork.
- Rock-Solid Net Metering: Washington’s Net Energy Metering (NEM) program allows you to bank your excess summer solar power at a 1:1 ratio with your utility (like Clark PUD). This turns the grid into a free, massive battery for your winter energy needs.
- Explore all current programs in our 2026 Washington State Solar Incentives Guide.
For Our Oregon Neighbors
If you live south of the river, your state relies heavily on direct cash rebates to lower the cost of solar, completely independent of your federal tax return.
- Energy Trust of Oregon (ETO) Rebates: If you are a Portland General Electric (PGE) or Pacific Power customer, the ETO provides upfront cash incentives that are deducted directly from your invoice.
- Solar Within Reach: For moderate-income households, the ETO offers elevated rebates that dramatically reduce the upfront cost of going solar, making it accessible to more families than ever before.
- Oregon Net Metering: Like Washington, Oregon utilities credit you for your overproduction, with an annual “true-up” every March to ensure you maximize your summer sunshine.

Do You Need a Battery in 2026?
With the federal tax changes, we are constantly asked if adding a battery is still worth the investment. The answer is a resounding yes, but the reasons have shifted from “tax write-offs” to “pure resilience.”
In the PNW, winter ice storms and high winds are a fact of life. When the grid goes down, standard solar panels shut off to protect utility workers. By adding a home battery backup system (like the Generac PWRCell 2 or Enphase IQ 5P), your home becomes an independent microgrid. Your lights stay on, your fridge stays cold, and your home business stays online. While you can’t claim a residential federal tax credit on the battery in 2026, programs like the Energy Trust of Oregon offer massive cash rebates specifically for battery installations to help stabilize the local grid.
