IRS Form 5695 Explained: Who Actually Benefits From the 30% Solar Tax Credit
Last updated: 2026-06-15
The Bottom Line First
The federal solar tax credit is worth 30% of your total installation cost — on a $30,000 system, that's $9,000 back. But here's what most solar salespeople won't tell you upfront: this credit is non-refundable. If you don't owe at least $9,000 in federal income taxes over the next several years, you won't capture the full value.
Retirees living primarily on Social Security, households with low tax liability, and renters are the groups most likely to leave money on the table — or qualify for nothing at all. This article breaks down exactly how the credit works, who gets the most out of it, who doesn't, and what alternatives exist if you fall into a gap.
What Is IRS Form 5695?
Form 5695 is the IRS form used to claim the Residential Clean Energy Credit — the official name for what everyone calls the solar tax credit. You file it alongside your annual federal return (Form 1040) for the year your solar system is placed in service. "Placed in service" means installed, inspected, and operational — not just ordered or contracted.
The form covers more than solar. It also applies to:
- Small wind turbines
- Geothermal heat pumps
- Battery storage systems (added under the Inflation Reduction Act)
- Fuel cells
For most homeowners, solar panels plus battery storage are the relevant line items. The math on the form is straightforward: take your total qualified costs, multiply by 30%, and that's your credit. What's less simple is understanding what that credit actually does — and what it doesn't do.
How the 30% Credit Actually Works
A tax credit reduces your tax bill dollar-for-dollar. This is fundamentally different from a tax deduction, which only reduces your taxable income.
Here's a concrete example:
> You install a $30,000 solar system in 2026.
> Your 30% credit = $9,000
> Your federal income tax liability for 2026 = $6,500
> Credit applied = $6,500 (wipes out your entire bill)
> Remaining credit = $2,500 — carried forward to 2027
That $2,500 doesn't disappear. It rolls over. But it also doesn't generate a refund — more on that in a moment.
What counts as a qualified cost?
The IRS allows you to include the full system cost: panels, inverters, wiring, mounting hardware, and labor for installation. Battery storage qualifies separately at 30% even if not paired with solar. If you add a battery to an existing system in a later year, you can claim that credit then.
Carryforward Rules Explained
Because the credit is non-refundable, many homeowners can't use all of it in the first year. The carryforward provision allows any unused credit to apply to next year's tax liability.
How far can you carry it?
The Residential Clean Energy Credit can be carried forward indefinitely for credit earned on systems installed before the December 31, 2025 expiration. If you installed solar or battery storage in 2025 or earlier and have unused credit, you can carry it forward year after year until it is fully used — the carryforward itself is not subject to the expiration. No new Section 25D credit can be earned for systems installed after December 31, 2025.
Carryforward example over three years:
| Year | Tax Liability | Credit Applied | Carryforward Remaining |
|------|--------------|----------------|------------------------|
| 2026 | $6,500 | $6,500 | $2,500 |
| 2027 | $7,200 | $2,500 | $0 |
| 2028 | $8,000 | $0 | $0 |
In this scenario, the full $9,000 is captured over two years. This works well for working-age homeowners with consistent income and predictable tax liability.
The risk: if your tax liability drops — due to retirement, job loss, or major deductions — the carryforward becomes harder to absorb.
Who Benefits Most From the Solar ITC
Working homeowners with mid-to-high income are the clear winners. A household paying $8,000–$15,000+ annually in federal income taxes can typically absorb a large credit in one or two years and maximize the full 30%.
Business owners and self-employed homeowners often have higher and more variable tax liabilities, making them well-positioned to plan credit absorption strategically — sometimes accelerating income recognition in the installation year.
Homeowners adding battery storage can layer multiple credits. A solar + battery install in the same year qualifies both components at 30%, and some states stack additional rebates on top.
Dual-income households generally have higher combined tax liability, giving them more capacity to absorb the credit quickly.
If you're in any of these categories and own your home with a south-facing roof in a state with decent solar irradiance, the math usually works strongly in your favor.
Who Doesn't Benefit — The Three Groups Left Out
1. Retirees With Low Tax Liability
This is the most important gap, and it affects millions of homeowners who are otherwise ideal solar candidates (own their home outright, have a good roof, high electricity bills).
Here's the problem: Social Security benefits are only partially taxable, and many retirees also draw from Roth accounts (tax-free). A retiree couple with $60,000 in annual income may owe only $2,000–$4,000 in federal taxes after standard deductions. A $9,000 credit sounds great — but if you're only absorbing $3,000/year, it takes three years to use it all, and there's no guarantee the carryforward remains usable if circumstances change.
What retirees should do:
- Get a tax projection from a CPA before signing a solar contract
- Consider timing the install in a year with higher-than-usual income (RMDs, property sale, IRA conversion)
- Evaluate leases or PPAs, which transfer the tax credit to the solar company in exchange for lower rates — you lose the credit but gain predictable savings without upfront cost
2. Low-Income Households
Households below roughly $40,000–$50,000 in annual income often pay little to no federal income tax after standard deductions, credits, and EITC. The solar credit is useless if there's no tax liability to offset.
For this group, the better path is often:
- State and utility rebates that work as direct discounts, not credits
- Low-income solar programs — some states run programs specifically for income-qualified households
- Solar leases or community solar subscriptions that don't require ownership or upfront cost
The Inflation Reduction Act created a separate Low-Income Communities Bonus Credit (an additional 10–20% on top of the 30%) for solar projects in certain census tracts, but this primarily applies to larger projects, not typical residential installs.
3. Renters
There is no path to the residential solar ITC for renters. The credit requires that you own both the property where the system is installed and the system itself. A landlord who installs solar for a rental property claims the credit on their taxes, not yours.
What renters can do:
- Community solar subscriptions — subscribe to a share of a larger solar farm and receive bill credits. No ownership required.
- Negotiate energy-efficient leases — some landlords pass utility savings through to tenants
- Advocate for solar on your building and ask if the landlord will share savings
How to File Form 5695
Filing is simpler than you'd expect. Here's the basic process:
- Collect your documentation — Get a final invoice from your installer showing the total system cost. Keep it with your tax records.
- Complete Part I of Form 5695 — Enter your qualified solar costs on Line 1. The form calculates the 30% automatically.
- Transfer to Schedule 3 — The credit flows to Schedule 3, Line 5, then to your Form 1040. Your tax software handles this automatically.
- Track your carryforward — If any credit remains unused, Part I of Form 5695 for next year is where you enter it. Don't lose track of this number.
One common mistake: filing Form 5695 for a year before your system was operational. The credit applies to the year the system is placed in service, not the year you signed the contract or made your first payment.
If you're using tax software, the Form 5695 interview is typically under the "Deductions and Credits" section. Most major software handles carryforward tracking automatically if you import last year's return.
We recommend comparing quotes from multiple installers before committing — the total system cost drives the entire credit calculation, and prices vary significantly by region and installer. EnergySage Solar Marketplace makes it easy to get competing quotes from pre-vetted installers in your area without the high-pressure sales experience.
