Quick answer: There is no California state solar tax credit, and there never has been one in the modern era. What most people mean by the term, the 30 percent federal residential credit, expired on December 31, 2025. What California homeowners still have in 2026: the federal 48E credit passed through lease and PPA pricing, SGIP battery rebates worth $200 to $1,100 per kWh depending on eligibility, a property tax exclusion that permanently shields your solar system from reassessment if it is completed before January 1, 2027, and full retail net metering on municipal utilities. Two of those have deadlines inside the next 18 months.
Key takeaways
- California has no state solar income tax credit. The state’s incentives are SGIP rebates, a property tax exclusion, and utility-level programs
- The federal 30 percent residential credit (Section 25D) expired December 31, 2025. Systems installed during 2025 can still be claimed on your 2025 tax return
- Leases and PPAs are now the only route to federal solar money: the leasing company claims the commercial 48E credit and passes it through as lower payments
- SGIP’s general budgets are mostly waitlisted, but income-qualified households can still get up to $1,100 per kWh for batteries plus $3,100 per kW for solar
- The quiet deadline: California’s solar property tax exclusion sunsets January 1, 2027. Install in 2026 and your system is permanently excluded from reassessment. Wait, and it may be taxed as new construction
Is there a California solar tax credit?
No. This is the first thing I would tell anyone searching the phrase, because the solar industry spent years letting the confusion slide: California does not offer a state income tax credit for solar panels. When a salesperson or an old article mentions “the California solar tax credit,” they mean the federal credit, which every state’s residents could claim, and which no longer exists for purchased systems.
What California actually offers is a different set of tools: a battery rebate program (SGIP), a property tax exclusion with a hard deadline, and, depending on your utility, net metering rules that are worth more than most tax credits ever were. The rest of this guide covers each one with current numbers.
What happened to the federal solar tax credit?
The Residential Clean Energy Credit, Section 25D of the tax code, paid homeowners 30 percent of a solar or battery purchase back at tax time. Congress repealed it in the One Big Beautiful Bill Act of July 2025, and it expired for any system installed after December 31, 2025 (Congressional Research Service).
Federal residential solar credit status by install date
| When your system was installed | Federal credit | What to do |
|---|---|---|
| 2022 through 2024 | 30% under Section 25D | Already claimable on that year’s return; unused credit carries forward |
| During 2025 | 30% under Section 25D | Claim it on your 2025 tax return with IRS Form 5695 if you have not already |
| January 1, 2026 or later, purchased | None | No federal credit exists for homeowner-purchased systems |
| 2026 or later, leased or PPA | Indirect, via 48E | The system owner claims the commercial credit and prices it into your payments |
One nuance worth money: the trigger is when the system was installed, not when you file. If your panels went live in November 2025 and you have not filed your 2025 return or claimed the credit, you still can.
Will Congress bring 25D back? Unknown, and I would not plan a purchase around hoping. Every month of a California electric bill is real money while you wait.
The lease and PPA route: the last federal money on the table
The commercial clean energy credit, Section 48E, survived the repeal and remains available through at least 2027 for third-party-owned systems. When a leasing company owns the panels on your roof, it claims that credit at the corporate level and, in a competitive market, passes the savings through as lower monthly payments.
This flips a decade of conventional wisdom. From 2016 through 2025, buying beat leasing for almost everyone with tax liability. In 2026, a well-structured lease or prepaid PPA is the only way any federal incentive touches your project, which is why third-party ownership is surging back. It comes with the same old fine print: you do not own the asset, escalator clauses of 2 to 3 percent compound painfully over 25 years, and a leased system complicates a home sale. We walk through the full decision in our solar lease vs buy vs PPA guide, and the honest summary is: cash or loan still wins on lifetime value for most homeowners, but the gap narrowed the day 25D died.
SGIP: California’s real remaining incentive
The Self-Generation Incentive Program is a CPUC-administered rebate for battery storage, paid per kWh of installed capacity, and in 2026 it is the most significant incentive still standing (CPUC SGIP program).
SGIP residential tiers, mid-2026 status
| Tier | Rebate | Who qualifies | Status |
|---|---|---|---|
| General Market | ~$150 to $200 per kWh | Any residential customer of PG&E, SCE, SDG&E, SoCalGas | Waitlisted in most territories, longest queues at PG&E |
| Equity | ~$850 per kWh | Income-qualified (below 80% of area median income) and other criteria | Limited, largely reserved |
| Equity Resiliency | ~$1,000 to $1,100 per kWh | Income-qualified or medical baseline in high fire-threat districts or PSPS-hit areas | Limited, largely reserved |
| Residential Solar & Storage Equity (RSSE) | Up to $1,100/kWh battery + $3,100/kW solar | Households below 80% AMI | Open with waitlist; $280M program, applications through 2028 |
What the tiers mean in dollars: on a standard 13.5 kWh home battery, General Market is roughly $2,700 back, Equity roughly $11,500, and the top tiers can approach the full installed cost. RSSE can genuinely produce a near-free solar-plus-battery system for a qualifying household, since the program’s cost cap simply stops the rebate at 100 percent of the installed price.
Two practical warnings from the field. First, apply and secure a confirmed reservation before installing; installing first can forfeit the rebate. Second, waitlists are real, running months to over a year in some territories, so build SGIP into your timeline rather than your assumptions. Our team handles the SGIP paperwork on qualifying battery installations, and the battery decision itself depends heavily on your utility, covered below.
The January 1, 2027 deadline almost nobody is talking about
Here is the section that should change your timing math. Since 1980, California has excluded active solar energy systems from property tax reassessment under Revenue and Taxation Code Section 73. Add $25,000 of solar to your home and your assessed value does not move. That exclusion sunsets on January 1, 2027, unless the legislature extends it (California Board of Equalization).
The BOE has clarified the mechanics: a system completed before January 1, 2027 keeps the exclusion permanently, until the property changes ownership. A system completed after that date may be assessed as taxable new construction (BOE Letter to Assessors 2024/031).
What that is worth: at a typical 1.1 percent effective property tax rate, a $25,000 system assessed as new construction would add roughly $275 per year to your property taxes, escalating with the standard 2 percent annual increases, for as long as you own the home. Call it $6,000 to $8,000 over 25 years. An extension bill (SB 710) has been proposed, but as of mid-2026 the sunset stands. Permitting, installation, and inspection take months, which makes 2026 installs safe and early-2027 gambles not.
Utility and local programs: the incentives hiding in your rate structure
A few programs worth knowing beyond the statewide picture. SMUD customers in Sacramento can earn up to $10,000 through the My Energy Optimizer Partner+ battery program, the most generous utility-level battery incentive in the state. Other municipal utilities run smaller rebates that come and go; ask before you sign.
The biggest “incentive” in California, though, is not labeled as one: your net metering rules. Municipal utilities like LADWP and Pasadena Water and Power still credit exported solar at retail rates, which is worth more over 25 years than the federal tax credit ever was; we ran those numbers in our Granada Hills and Pasadena guides. On SCE, PG&E, and SDG&E under NEM 3.0, exports earn a fraction of retail, which is exactly why SGIP pushes batteries and why battery attach rates keep climbing.
What this means if you are going solar in 2026
The 2026 decision matrix
| Your situation | Best available incentives | Bottom line |
|---|---|---|
| Cash or loan buyer, any income | Property tax exclusion (install by 12/31/2026), SGIP General Market if adding a battery, muni net metering if applicable | No tax credit, but paybacks of 5 to 7 years still stand on the strength of California rates alone |
| Household below 80% AMI | SGIP RSSE: up to $1,100/kWh + $3,100/kW, potentially covering the full system | Get on the waitlist now; do not install before the reservation letter |
| No appetite for upfront cost | Lease or PPA carrying the 48E credit in its pricing | Read the escalator clause; compare against a loan before signing |
| On LADWP, SMUD, PWP, or another muni | Retail net metering + property tax exclusion + any utility rebate | The strongest solar economics in the state, credit or no credit |
The honest close: California solar in 2026 lost its most famous incentive and kept the things that actually drive the math, which are the highest electricity rates in the continental US and, for now, a property tax shield with 5 months of guaranteed runway. Our 5kW cost and output guide shows the no-credit paybacks in detail, and our statewide installer rankings cover who to get quotes from.
FAQ
Does California have a state solar tax credit?
No. California has never offered a state income tax credit for residential solar in the modern era. The state’s incentives are SGIP battery rebates, the property tax exclusion for systems completed before January 1, 2027, and utility-level programs.
Can I still get the 30 percent solar tax credit in 2026?
Not on a purchased system. Section 25D expired December 31, 2025. The only remaining path to federal incentive money is a lease or PPA, where the system owner claims the commercial 48E credit and reflects it in your payments.
I installed solar in 2025 but have not claimed the credit. Am I too late?
No. The credit follows the installation date, not the filing date. Claim it on your 2025 return using IRS Form 5695, and unused credit amounts carry forward.
How much is the SGIP rebate in 2026?
Roughly $150 to $200 per kWh at the General Market tier, about $850 per kWh at the Equity tier, and up to $1,100 per kWh, plus $3,100 per kW for solar, under the income-qualified RSSE budget. On a 13.5 kWh battery that ranges from about $2,700 to over $13,000. Most budgets carry waitlists, so apply before you install.
Will the federal solar tax credit come back?
Unknown. Reinstating it would take an act of Congress, and nothing pending suggests imminent change. Waiting for a credit that may never return means paying full California electric rates in the meantime, which is usually the more expensive choice.
What is the property tax benefit for solar in California?
Systems completed before January 1, 2027 are excluded from property tax reassessment permanently, until the home changes ownership. After the sunset, new installations may be assessed as new construction, worth roughly $275 per year in added tax on a typical $25,000 system.
