How to Fill Out IRS Form 5695 for Solar & Battery Storage (2026 Line-by-Line Instructions)
Claiming the 30% Residential Clean Energy Credit (IRC Section 25D) requires completing Part I of IRS Form 5695 and transferring the credit to Schedule 3 (Form 1040), Line 5a. Walk through every single line from Line 1 to Line 16 with real dollar examples.
📋 Official IRS Line-by-Line & Statutory Breakdown
Enter the total gross contract price paid for solar panels, microinverters/string inverters, racking, wiring, permitting fees, and installation labor placed in service during the tax year. Do NOT include roof replacement shingles or extended warranty service plans.
Check "Yes" on Line 5a confirming your home battery has a nameplate capacity of at least 3 kilowatt-hours (e.g., 13.5 kWh Powerwall 3 or 14.3 kWh EG4 PowerPro). Enter the total installed cost of the battery system on Line 5b (if billed separately from Line 1).
Line 6a sums Lines 1 through 5b. Multiply Line 6a by 30% (0.30) and enter the result on Line 6b. Example: $24,000 solar + $10,000 battery = $34,000 on Line 6a -> $10,200 credit on Line 6b.
If your 30% solar credit last year was larger than your federal income tax liability, enter the unused carryforward amount from last year's Form 5695, Line 16 here.
Enter your total federal income tax liability from the Residential Clean Energy Credit Limit Worksheet (roughly Form 1040, Line 18 minus certain non-refundable credits). Because Section 25D is a non-refundable credit, it can reduce your tax liability to $0 (triggering a refund of all W-2 taxes withheld during the year!).
Line 15 is the smaller of Line 13 or Line 14 (transfer this exact number to Schedule 3 [Form 1040], Line 5a). If Line 13 exceeds Line 14, subtract Line 15 from Line 13 and enter the remainder on Line 16 to carry forward automatically to next year!
🚨 IRS Compliance & Audit Red Flags
- ⚠️Utility Rebate Basis Reduction Rule (IRS Notice 2013-70): If your electric utility pays you a nontaxable cash rebate for installing solar or a battery (e.g., SGIP or utility solar rebate), you MUST subtract that rebate from your cost basis BEFORE multiplying by 30%. However, taxable state SRECs do NOT reduce your federal basis!
- ⚠️Placed-in-Service Date Rule: You can only claim Form 5695 for the tax year in which installation is completed and ready for operation—not the year you merely signed a contract or paid a deposit.
- ⚠️DIY Hardware Eligibility: If you buy UL-listed solar panels, an EG4 18kPV inverter, and LFP batteries yourself, 100% of your equipment, wire, conduit, and permit receipts qualify on Line 1 and Line 5b (you just cannot charge for your own unpaid DIY labor).
Frequently Asked Questions: IRS Form 5695 Line-by-Line Guide
Do I still get a tax refund check from the IRS if the 30% solar credit is "non-refundable"?
Yes, if you have W-2 paycheck withholding! "Non-refundable" simply means the credit caps at your total annual tax liability (Form 1040 Line 18). If your total tax liability for the year was $9,000 and your employer already withheld $9,000 from your paychecks, a $9,000 solar tax credit drops your tax owed to $0—so the IRS mails you a $9,000 refund check for the taxes your employer withheld!
