What Is the Solar Federal Tax Credit in 2026?
The Residential Clean Energy Credit — commonly called the solar investment tax credit (ITC) — lets homeowners deduct 30% of their solar panel system costs directly from federal income taxes. Extended by the Inflation Reduction Act (IRA) in 2022, the 30% rate applies through 2032.
For a $25,000 solar installation, the credit equals $7,500 off your tax bill. No income cap applies.

How to Complete IRS Form 5695 for Solar (Step-by-Step)
1
Gather your solar installation documents
Collect the final invoice, proof of payment, installer certification, and any state/utility rebates received.
2
Download Form 5695 (2025 version)
Get the current version from IRS.gov. Use Part I (Lines 1–14) for the Residential Clean Energy Credit.
3
Enter qualified solar costs on Line 1
Total all eligible expenses. Subtract any utility rebates or state grants. Enter the net qualified cost on Line 1.
4
Calculate 30% on Line 6b
Multiply Line 1 by 0.30. This is your tentative credit amount.
5
Apply carryforward from prior year (Line 12)
If you had unused credit from prior years, enter it on Line 12. Total credits carry forward automatically.
6
Transfer to Schedule 3 (Form 1040), Line 5
The amount from Form 5695 Line 14 goes to Schedule 3, Part I, Line 5. This reduces your total tax liability.
7
Attach Form 5695 to your return
File electronically or attach the paper form. Keep your installer invoice for at least 7 years.
Example: $28,000 system − $1,500 state rebate = $26,500 qualified cost × 30% = $7,950 federal tax credit. If your tax bill is $6,000, you get $6,000 off and carry forward $1,950 to next year.
Solar Tax Credit Schedule: 30% Through 2032
| Tax Year | Credit Rate | Status |
|---|
| 2022–2032 | 30% | Current (IRA-extended) |
| 2033 | 26% | Step-down scheduled |
| 2034 | 22% | Step-down scheduled |
| 2035+ | 0% | Expires unless extended |
Note: Congress could modify these rates in future legislation. Installing before 2033 locks in the 30% rate for that tax year.
Financed Systems: Loan vs. Lease vs. PPA
| Financing Type | Credit Eligible? | Why |
|---|
| Cash purchase | Yes | You own the system |
| Solar loan | Yes | You own the system |
| Home equity loan | Yes | You own the system |
| Solar lease | No | Installer owns the system |
| PPA (Power Purchase Agreement) | No | Installer owns the system |
