IRS Form 5695: How to Claim the Solar Tax Credit in 2026

You installed solar panels. You know you qualify for the 30% federal tax credit. Now comes the part most guides skip: actually filling out IRS Form 5695 and claiming the money.

This guide walks through every line of Form 5695, with a worked example for a real homeowner, plus the most common mistakes that delay or reduce refunds.

Quick answer: The residential clean energy credit (formerly Investment Tax Credit) is claimed on IRS Form 5695, Part I. You attach it to your federal income tax return (Form 1040). The credit reduces your tax bill dollar-for-dollar; any unused credit carries forward to the next tax year.

What Is the Residential Clean Energy Credit?

The Residential Clean Energy Credit — commonly called the solar ITC — was extended and expanded by the Inflation Reduction Act of 2022. For systems installed between 2022 and 2032, the credit is 30% of qualifying costs with no cap.

Eligible costs include:

• Solar PV panels and mounting equipment
• Inverters (string, micro, and hybrid)
• Wiring and electrical equipment (including sub-panels added specifically for solar)
• Installation labor (permits, design fees, electrician labor)
• Battery storage systems installed with solar (and standalone batteries with ≥3 kWh capacity installed after January 1, 2023)
• Energy storage devices charged by the solar system

Not eligible: Roof repairs done before or during installation (only the portion required for panel mounting), extended warranties beyond manufacturer coverage, or monitoring subscriptions.

The credit is non-refundable — it can reduce your tax liability to zero, but you will not receive a cash refund for any excess. Unused credit carries forward indefinitely until used.

---

Who Can Claim It?

You can claim the Residential Clean Energy Credit if:

• You are the owner of the solar system (not leasing or under a PPA)
• The system is installed at your primary or secondary residence in the United States
• You have federal income tax liability in the tax year (or in future years if carrying forward)
• The system was placed in service (i.e., received Permission to Operate from your utility) in that tax year

Renters: If you own the system but rent your home (paying rent with a solar system you installed), you may still qualify. Consult a tax professional.

Businesses: Business installations use Form 3468 (Investment Credit), not Form 5695. The rules are different — see the commercial solar guide for Section 48 ITC details.

Retirees and low earners: If your federal tax liability is less than the credit, you carry forward the unused portion. The credit does not become a refund check. See the seniors solar guide for how to use carry-forwards on fixed income.

When to File Form 5695

File Form 5695 for the tax year in which the solar system was placed in service — that is, the year you received your Permission to Operate (PTO) letter from the utility, not when you signed the contract or when installation was physically completed.

• Signed contract: January 2026
• Physical installation: March 2026
• Utility PTO issued: May 2026 → File Form 5695 with your 2026 tax return (due April 2027, or October 2027 with extension)

If installation straddled two tax years (physically done in December but PTO came in January), the credit belongs to the year PTO was issued.

Line-by-Line Instructions: Form 5695 Part I

Below is a detailed walkthrough of Part I of Form 5695 (Residential Clean Energy Credit). The line numbers below match the 2025 version of the form; minor layout changes may occur in the 2026 version but the logic is identical.

Setting Up: The Worked Example

Homeowner: Jane, single filer, Richmond, Virginia
System: 9 kW solar PV + 10 kWh battery, installed May 2026
Total cost (what she paid):

• Panels and racking: $19,800
• Inverter: $3,200
• Battery (LFP, ≥3 kWh): $8,500
• Installation labor, permits, engineering: $4,500
• Electrical sub-panel upgrade (required for battery): $2,100
• Extended roof repair (not required for panels): $1,400 ← NOT eligible
• Total eligible cost: $19,800 + $3,200 + $8,500 + $4,500 + $2,100 = $38,100
• 30% credit: $38,100 × 0.30 = $11,430

Jane's federal tax liability this year: $9,200

Part I — Residential Clean Energy Credit

Line 1: Qualified solar electric property costs.
Enter the total amount you paid for solar PV panels, inverters, wiring, labor, and racking. Do not include the battery here if it qualifies separately.

Jane enters: $30,000 (panels + inverter + labor + sub-panel)

Line 2: Qualified solar water heating property costs.
For solar water heaters that meet Energy Star requirements. Most residential solar-electric customers: enter $0 here.

Jane enters: $0

Line 3: Qualified fuel cell property costs.
For fuel cell systems producing electricity (rare for homeowners). Most: enter $0.

Jane enters: $0

Line 4: Qualified small wind energy property costs.
For residential wind turbines (uncommon). Most solar-only customers: enter $0.

Jane enters: $0

Line 5: Qualified geothermal heat pump property costs.
If you also installed a geothermal heat pump. Jane didn't, so: $0.

Jane enters: $0

Line 6: Qualified battery storage technology costs.
Enter the total cost of eligible battery storage. Batteries must have a capacity of at least 3 kilowatt-hours. The battery does not need to be charged exclusively by solar (IRA 2023 rule); it simply needs ≥3 kWh usable capacity.

Jane enters: $8,100 (battery cost $8,500 minus $400 installation labor already included in Line 1)

Note: If your installer gave you a single bundled quote, ask for a cost breakdown. Labor to install the battery is often separable; some installers include it in the equipment line.

Lines 7–11: Sum of Lines 1 through 6, then multiply by the credit rate.

Line 7: Add Lines 1–6.

Jane: $30,000 + $0 + $0 + $0 + $0 + $8,100 = $38,100

Line 8: Credit rate (30% for systems placed in service 2022–2032).

This is pre-printed as a percentage on the form. Multiply Line 7 × 0.30.
Jane: $38,100 × 0.30 = $11,430

Line 9: If you are claiming a fuel cell credit, subtract the applicable limitation.
Most homeowners: skip or enter $0.

Jane: $11,430 (unchanged)

Line 10: Residential Clean Energy Credit Carryforward from Prior Year.
If you have an unused credit from a prior year's Form 5695, enter it here.

Jane (first claim): $0

Line 11: Add Lines 9 and 10. This is your available credit for the year.

Jane: $11,430 + $0 = $11,430

Line 12: Limitation based on tax liability.
This is calculated using a separate worksheet (Part II of Form 5695 or your tax software does it automatically). It caps the credit at your actual federal tax liability minus other credits you claim.

For simplicity: if you have no other non-refundable credits, Line 12 ≈ your total federal tax liability.

Jane's tax liability: $9,200

Line 13: Residential Clean Energy Credit. Enter the smaller of Line 11 or Line 12.

Jane: smaller of $11,430 or $9,200 = $9,200

This $9,200 reduces Jane's federal tax bill to $0.

Line 14: Credit Carryforward to Next Year.
Subtract Line 13 from Line 11.

Jane: $11,430 − $9,200 = $2,230 carries forward to 2027

Jane will claim $2,230 on her 2027 Form 5695, Line 10.

---

Where Form 5695 Flows on Your 1040

After completing Form 5695:

• The credit amount from Line 13 flows to Schedule 3 (Additional Credits and Payments), Line 5 (Residential Clean Energy Credit)
• Schedule 3 totals flow to Form 1040, Line 20
• This reduces your total tax on Line 24

Your tax software handles these connections automatically. When doing it by hand, complete Form 5695 → Schedule 3 → 1040 in that order.

---

Carryforward: What Happens to Unused Credit

The residential clean energy credit is permanently nonrefundable, but any unused portion carries forward indefinitely.

Year 1 (2026): Jane claims $9,200 of her $11,430 credit. Carries forward $2,230.
Year 2 (2027): Jane enters $2,230 on Line 10. If her tax liability is $9,000+, she uses all of it. If she owes $1,800, she carries forward $430.

Carryforwards do not expire under current law. They are lost only if:

• The taxpayer dies (the estate cannot use them)
• The solar system is disposed of before full carryforward is used (partial recapture rules may apply)

Energy Community Bonus: 40% Credit

If your home or primary residence is located in an IRS-designated Energy Community, your credit rate may be 40% instead of 30%. Energy Communities are areas affected by fossil fuel industry layoffs or closures — many rural communities in coal, oil, gas, and manufacturing regions qualify.

To check Energy Community eligibility:

1. Go to the IRS Energy Community Tool at energycommunities.gov (or the Department of Energy's equivalent)
2. Enter your address
3. Print or screenshot the result — attach it to your tax records

If eligible, the credit is still claimed on Form 5695 using the same lines, but the rate used in Line 8 would be 40% rather than 30%. As of the current Form 5695, the form uses 30% as the default — your tax professional or software must manually apply the 40% rate if you qualify. Document your Energy Community eligibility carefully.

For a complete list of high-EC states, see the Virginia solar guide, West Virginia guide, and Kentucky guide — Appalachian coal counties in particular have very broad eligibility.

Common Mistakes That Delay or Reduce Your Credit

1. Using "Installation Date" Instead of PTO Date

The credit belongs to the year Permission to Operate was issued by your utility — not when panels went on the roof. Filing in the wrong year means amending returns later.

2. Including Non-Eligible Roof Repairs

Roof repairs not directly required for the solar installation do not qualify. The IRS distinguishes "structural components" made to support panels from general roof maintenance. When in doubt, exclude it and consult a CPA.

3. Including Leased Equipment

If you signed a lease or PPA (you pay a monthly bill and don't own the panels), you do not own the solar system and cannot claim the ITC. The leasing company claims the credit. Verify your contract type before filing.

4. Forgetting Battery Storage

If your installer bundled the battery into a single line-item price, ask for the battery cost breakdown. Batteries installed on or after January 1, 2023 with ≥3 kWh capacity qualify whether charged by solar or grid — include them on Line 6.

5. Forgetting Sub-Panel Upgrades

If your installer upgraded your electrical panel specifically to support the solar or battery system (not as a general home improvement), those costs are eligible. They go on Line 1 as part of solar electric property costs.

6. Missing the Carryforward on Next Year's Return

Carryforwards don't carry automatically — you must enter them manually on Line 10 of Form 5695 in the subsequent year. Set a reminder when you file: "Check prior-year Form 5695 Line 14 for carryforward."

7. Filing Without Proof of PTO

Keep your Permission to Operate letter, the signed installation contract with itemized costs, and any manufacturer certifications (required for some property types). The IRS may ask for documentation when auditing energy credits.

Worked Example Summary Table

Item	Amount
Total eligible cost	$38,100
Carryforward from prior year	$0
30% credit calculated	$11,430
2026 tax liability	$9,200
Credit used in 2026	$9,200
Credit carried to 2027	$2,230
Net system cost after credit	$38,100 − $9,200 = $28,900*

*The remaining $2,230 will further reduce net cost when used in 2027.

What If I Financed With a Solar Loan?

If you took a solar loan, you still own the system — you can claim the ITC. Many homeowners use the credit refund as a lump-sum payment against the loan principal.

Common approach: File your 2026 return in February or March 2027. When you receive the tax refund (or reduce withholding), apply the credit amount directly to your solar loan principal. This strategy dramatically reduces your effective interest cost.

For the complete cash vs. loan vs. lease financial analysis, see the solar financing options guide.

State Tax Credits: Different Form, Same Logic

Many states offer their own solar income tax credits in addition to the federal ITC:

• New York: 25% state credit (up to $5,000) — NY Form IT-255
• South Carolina: 25% state credit (up to $3,500/year, 10-year carry) — SC I-335
• Oregon: 30% RETC (up to $6,000) — Oregon Form OR-ERC
• Massachusetts: 15% state credit (up to $1,000) — MA Schedule EC
• Utah: 25% state credit (up to $1,600) — Utah TC-40E

State credits are claimed separately using state-specific forms and are typically calculated on the same cost basis as the federal credit. They do not reduce the basis for the federal credit. See your state's dedicated guide for details:

• California solar incentives
• New York solar incentives
• Texas solar incentives
• Florida solar incentives
• All 50 state solar incentive guides

Frequently Asked Questions

Can I claim the credit if I didn't owe taxes this year?
Yes — the unused credit carries forward to future years. You will eventually use it as long as you have federal tax liability at some point before the carryforward expires (which is indefinitely under current law).

Can I claim the credit if my spouse owned the home before we married?
As long as the system is installed at your primary or secondary residence and you file jointly, you can claim the credit. Married filing separately complicates things — consult a tax professional.

Does the credit apply to systems on vacation homes or rental properties?
A secondary residence (vacation home you use personally) qualifies. A pure rental property does not qualify for the residential credit (Form 5695) — a rental property would use the commercial/business credit rules (Form 3468).

Do I need to itemize deductions to claim the solar credit?
No. The residential clean energy credit is a tax credit, not a deduction. You claim it on Schedule 3 regardless of whether you take the standard deduction or itemize. Most homeowners take the standard deduction and still claim the full solar ITC.

What documentation should I keep?
Keep for at least 3 years (7 years if the credit is large and you carry it forward): the signed contract with itemized costs, the manufacturer's certification statement, the utility PTO letter, the completion/inspection certificate, and your filed Form 5695.

If my installer goes out of business, can I still claim the credit?
Yes. The credit belongs to you (the system owner) based on your actual costs paid. Retain your own copies of all receipts and the contract — you do not depend on the installer to document your claim.

Next Steps

1. Find your total eligible system cost: Ask your installer for an itemized cost breakdown that separates panels, inverter, battery, labor, and permits. Verify which items are eligible using the list above.

2. Determine your PTO date: Locate your Permission to Operate letter from your utility. This is the date your system was "placed in service."

3. Use tax software or a CPA: Enter your costs in the energy credits section. All major software programs (TurboTax, H&R Block, TaxAct, FreeTaxUSA) include Form 5695. Verify the form is included with your package before filing.

4. Check for Energy Community eligibility: Visit energycommunities.gov to see if your address qualifies for the 40% rate.

5. Plan your carryforward: If your credit exceeds your current tax liability, note the carryforward amount and enter it on next year's Form 5695.

Before installation, use the solar payback calculator to model how the ITC affects your break-even timeline, and the how to save money on solar guide to maximize the financial benefit of your system.
