Eligible costs generally include equipment, onsite preparation, trenching or drilling, ground loops, and labor for installation, piping, and wiring. Keep itemized invoices and manufacturer documentation. Rebates can reduce your project basis, so track them carefully to maximize your federal tax benefit without running into calculation surprises.

State and Local Incentives That Stack With Federal Credits

Property and sales tax advantages

Some states offer property tax exemptions for renewable energy improvements or sales tax waivers on qualifying geothermal equipment. While rules vary by location, these incentives can significantly trim upfront costs. Ask your local assessor’s office and energy department, and share findings with our readers to help neighbors save too.

Utility rebates and performance bonuses

Utility companies may provide rebates for high-efficiency geothermal installations, demand-response participation, or verified performance. These incentives can arrive as post-install checks or bill credits. Track every award and keep copies of your rebate letters to ensure your federal credit basis is calculated correctly and transparently.

Finding programs without the hassle

Start with your state energy office and the Database of State Incentives for Renewables and Efficiency. Call your utility’s efficiency team and ask about geothermal specifically.

Eligibility, Paperwork, and Filing Without Stress

The core filing package you’ll need

Collect detailed invoices, proof of payment, installation dates, a manufacturer certification statement, and permit approvals if applicable. You will typically file IRS Form 5695 for the Residential Clean Energy Credit. Keep digital copies in a secure folder named by year so your documentation is always within reach.

Avoiding common mistakes

Double-check that project costs match your invoices after subtracting rebates that reduce basis. Verify the placed-in-service date aligns with your tax year. If you lease equipment, ask about ownership criteria. When in doubt, consult a tax professional to avoid delays, amended returns, or missed carryforward opportunities.

Carryforward considerations

If your federal credit exceeds your tax liability, you may be able to carry forward unused amounts to future tax years under IRS rules. Track remaining credits in a simple spreadsheet, note each year’s usage, and set calendar reminders so those valuable dollars never slip through the cracks.
