What Is the 30% Federal Solar Investment Tax Credit?

The ITC is a federal program that allows taxpayers to claim 30% of the total cost of installing eligible renewable energy systems on their federal income tax return. The credit is part of the government’s push to incentivize clean energy adoption and reduce greenhouse gas emissions.

The legislation governing this tax credit is outlined in the Internal Revenue Code Section 25D. According to the U.S. Department of Energy:

“The Residential Clean Energy Credit covers qualified solar electric property expenditures, including installation costs, with a credit equal to 30% of eligible expenses for systems placed in service between January 1, 2022, and December 31, 2032.”

2. Get a Professional Assessment

  • Contact certified installers like Rizzo Electric USA for a consultation.
  • Request an itemized quote covering all eligible expenses (solar panels, Powerwalls, electrical upgrades, permits, and labor).

3. Install the System

  • Proceed with the installation of your renewable energy system.
  • Keep all invoices, contracts, and receipts for tax purposes.

4. File IRS Form 5695

  • Use IRS Form 5695 (Residential Energy Credits) to claim the ITC.
  • Calculate 30% of your total eligible costs and enter the amount in the designated section of the form.
  • Attach the form to your federal income tax return.

5. Understand Your Refund Timeline

  • The credit reduces the amount of tax you owe for the year the system was installed.
  • If your tax liability is less than the credit amount, the unused portion rolls over to the next tax year.
  • Expect to see the credit applied during the standard tax refund schedule after filing.

6. Consult a Tax Professional

  • If you’re unsure about any part of the process, work with a CPA or tax advisor to ensure you maximize your credit.
