Federal Solar Tax Credit Guide: How to Claim the 30% ITC

The federal Solar Investment Tax Credit (ITC) is the single most valuable incentive for going solar. Here's everything you need to know about claiming this credit.

What Is the Solar ITC?

The Investment Tax Credit allows you to deduct 30% of the total cost of your solar energy system from your federal income taxes. This is a tax credit, not a deduction — it directly reduces the amount of tax you owe, dollar for dollar.

What Costs Are Eligible?

The ITC covers the full cost of your solar installation, including:

Solar panels

Inverters

Mounting hardware and racking

Wiring and electrical components

Labor and installation costs

Permitting fees

Sales tax on the system

Battery storage (if installed with solar)

Engineering and design costs

Eligibility Requirements

To qualify for the federal solar ITC:

You must own the system — leased systems and PPAs don't qualify (the leasing company claims the credit)

The system must be new — used or refurbished equipment doesn't qualify

It must be installed on a US property — you must be a US taxpayer

You need sufficient tax liability — the credit reduces your tax bill, so you need to owe enough in taxes

The system must be "placed in service" during the tax year — meaning operational and connected

How to Claim the Credit: Step by Step

Complete your solar installation and receive your final invoice showing the total system cost

Obtain IRS Form 5695 (Residential Energy Credits) from irs.gov

Calculate your credit by multiplying your total system cost by 30%

File Form 5695 with your annual federal tax return (Form 1040)

Enter the credit amount on your Form 1040 to reduce your tax liability

Carryforward Rules

If your solar tax credit exceeds your tax liability for the year, you can carry the unused portion forward to future tax years. There's no limit on how many years you can carry it forward, so you'll eventually claim the full amount.

Timeline

30% credit: Systems installed 2022 through December 31, 2032

26% credit: Systems installed in 2033

22% credit: Systems installed in 2034

0% credit: The residential credit expires after 2034 (unless extended)

Example Calculation

For a $24,000 solar system installed in 2026:

System cost: $24,000

30% ITC: $24,000 × 0.30 = $7,200 tax credit

Net cost: $24,000 - $7,200 = $16,800

If you also qualify for a state tax credit (e.g., New York's 25% up to $5,000), your net cost drops even further.

Common Mistakes to Avoid

Forgetting to include sales tax in the eligible amount

Not filing Form 5695 with your tax return

Assuming the credit is a refund (it only reduces tax owed)

Waiting too long — the credit decreases after 2032

Leasing instead of buying and missing the credit entirely
