The federal solar tax credit (IRS Section 25D) covers 30% of your total solar installation costs — with no dollar cap. For a typical $20,000 system, that's a $6,000 credit that directly reduces your tax bill. This guide explains exactly how it works, what qualifies, and how to maximize savings by stacking with state programs.
| Credit Amount | 30% of total installation costs (no cap) |
| IRS Section | Section 25D — Residential Clean Energy Credit |
| Available Through | 30% through 2032, 26% in 2033, 22% in 2034 |
| Typical Savings | $4,000 – $12,000 |
| Credit Type | Nonrefundable (reduces tax owed, carries forward) |
| Stacks With | State solar credits, HOMES rebates, utility incentives |
| How to Claim | IRS Form 5695 filed with your annual tax return |

The Residential Clean Energy Credit covers the full cost of purchasing and installing a solar energy system on your primary or secondary residence. Here's what counts:
The federal solar tax credit has broad eligibility. There is no income limit and no cap on the credit amount. You must meet these requirements:
You own the solar energy system (leased systems and PPAs do not qualify)
The system is installed on your primary or secondary residence in the U.S.
The system is new or being used for the first time (not previously installed elsewhere)
You have sufficient federal tax liability to use the credit (or can carry it forward)
You file IRS Form 5695 with your annual tax return
Important: Rental properties don't qualify
The Section 25D credit is only for your personal residence. If you install solar on a rental property, you may qualify for the Section 48 commercial credit instead — consult a tax professional.
Claiming the solar tax credit is straightforward. You'll need IRS Form 5695 and documentation from your installer. Here's the step-by-step process:
Complete installation and pass inspection. Keep all invoices, contracts, and receipts — you'll need the total cost.
Your solar company should provide a certificate of completion, itemized invoice, and confirmation that the system meets code requirements.
Enter your total solar costs on Part I of Form 5695. The form calculates your 30% credit automatically.
The credit amount from Form 5695 flows to Schedule 3, then to your Form 1040. It reduces your total tax liability.
If your credit exceeds your tax bill, the unused portion carries forward to future tax years — it doesn't expire.
Yes — and this is where real savings multiply. The federal solar credit stacks with state tax credits, HOMES rebates, utility incentives, and battery storage programs. Here are the best stacking opportunities by state:
The Inflation Reduction Act locked in the solar credit rate through 2034, but it decreases over time. Acting sooner means a larger credit:
| Tax Year | Credit Rate | Example ($25K system) |
|---|---|---|
| 2022 – 2032 | 30% | $7,500 |
| 2033 | 26% | $6,500 |
| 2034 | 22% | $5,500 |
| 2035+ | 0% (unless extended) | $0 |
