Quick overview
Home energy tax credits are dollar-for-dollar reductions in federal income tax for eligible energy-efficiency and renewable-energy investments in your residence. These credits are designed to lower the net cost of upgrades such as solar panels, energy storage systems, heat pumps, high-efficiency HVAC, and certain insulation or window improvements. The rules, credit amounts, and eligible technologies are set by federal tax law and implemented by the IRS — most individuals claim these credits using IRS Form 5695. (See IRS guidance: https://www.irs.gov/credits-deductions/individuals/home-energy-credits)
This guide explains who usually qualifies, which improvements are commonly covered, a step-by-step claim process, recordkeeping best practices, common mistakes, and real-world examples to help you calculate potential savings.
Who typically qualifies
- Homeowners who own and live in the qualifying residence (primary residence and, in many cases, second homes) are the typical beneficiaries. The property generally must be located in the U.S. and be eligible under IRS rules.
- Rental properties, commercial properties, or projects owned by partnerships or corporations follow different rules and may not use the same residential credits. If you own rentals, check IRS guidance or consult a tax pro.
IRS guidance is the final authority for eligibility and limitations: https://www.irs.gov/credits-deductions/individuals/home-energy-credits.
Common eligible improvements (high-level)
- Solar photovoltaic (PV) systems and solar water heating systems
- Battery energy storage systems placed in service with or after certain tax years
- Geothermal heat pumps
- Small wind turbines (where eligible)
- Qualified biomass fuel property
- Qualified energy-efficiency improvements (depending on the specific credit program)
Note: Precise eligibility, credit percentages, caps, and effective dates can vary by statute (for example, provisions from the Inflation Reduction Act) and IRS interpretation.

How the tax credit generally works (step-by-step)
- Confirm the credit that applies to your project
- The Residential Clean Energy Credit (IRC Section 25D, commonly claimed on Form 5695) covers many renewable installations like solar, geothermal, wind, and certain energy storage systems. (IRS: Residential Clean Energy Credit.)
- Other credits or rebates (state or utility) may apply separately. Federal credits reduce federal income tax; state incentives vary.
- Verify product and contractor eligibility
- Ask for manufacturer certification statements and product model numbers. Some credits require the equipment or manufacturer to meet efficiency standards or to be listed on a qualifying database. Keep warranties and installation contracts.
- Keep complete records at purchase and installation
- Save invoices, proof of payment, manufacturer certifications, contractor licenses, and permit documents. Record dates the system was placed in service—credits are based on when equipment is placed in service, not when ordered.
- Calculate the credit
- The credit is usually a percentage of qualified costs (for example, solar systems historically qualified at a percentage of cost). Certain upgrades have caps or annual limits. If your credit exceeds your tax liability, many residential credits allow carryforward to the next tax year; check the current IRS rules for carryforward limits.
- Complete IRS Form 5695
- Form 5695 is the form commonly used to claim residential energy credits and to calculate carryforwards. Enter the qualified costs, compute the credit, and transfer the allowable credit to the appropriate line on Form 1040.
- File your return
- Attach Form 5695 with your Form 1040 (or include it via e-file). Keep copies of all supporting documentation for at least three years (some advisors recommend keeping documents for up to seven years if carryforwards or audits are possible).
- Monitor for updates
- Tax rules change. Always confirm current-year rates, caps, or bonus credit provisions (for example, domestic content or location-based add-ons) before finalizing your tax return.

Practical example
Example: Installed solar PV system
- Purchased and installed: $15,000 (solar panels, inverters, installation)
- If the applicable federal credit is 30% for the tax year in which the system was placed in service, your tax credit = $15,000 × 30% = $4,500.
- If your federal tax liability for the year is $3,000, you may be able to apply $3,000 in the current year and carry forward the remaining $1,500 into the next tax year if the credit rules allow carryforward.
Note: The percentage and carryforward rules are set by statute and updated over time. Confirm current percentage and carryforward treatment on the IRS site before calculating.
Important documentation to keep
- Sales receipts and final invoices listing equipment model numbers and installation costs
- Manufacturer certification statements that the product qualifies for the credit
- Cancelled checks, credit card statements, or other proof of payment
- Installation contracts and permits showing the date the property was placed in service
- Copies of your filed Form 5695 and any worksheets used to calculate the credit
Keeping these documents reduces the chance of delays or audit adjustments.
Common mistakes and how to avoid them
- Assuming every home improvement qualifies: Only specifically listed equipment and improvements qualify. Verify before you buy.
- Missing placement-in-service dates: The credit applies to the year the equipment was placed in service, not purchase date.
- Not verifying product eligibility: Some items must meet energy-efficiency or manufacturer certification standards.
- Forgetting to claim carryforward: If the credit exceeds your tax liability, track unused amounts and claim them in subsequent years if allowed.
- Failing to account for other incentives: Utility rebates can affect the basis for credit calculations in some cases; read IRS rules about basis reduction.
Special cases and clarifications
- Leased systems: If you lease a system (e.g., solar), the lessor often claims the federal credit, not the lessee. If you purchase or are the original owner of a system, you typically claim the credit.
- Community/shared solar: Rules differ for subscriptions to community solar; consult IRS guidance and your project’s documentation.
- Rentals and business property: Different rules apply for properties held for rent or used in a trade or business; those incentives are typically claimed differently (depreciation, business credits, or state incentives).
Filing logistics: Form 5695 and Form 1040
- Use Form 5695 (Residential Energy Credits) to compute the credit and any carryforward. Transfer the allowable credit to your Form 1040.
- If you e-file, most tax software supports Form 5695 entry and will help you calculate the credit. Keep all supporting documents in case of IRS inquiries.

Professional tips
- Ask for a manufacturer certification at time of purchase and confirm the installer’s credentials.
- Combine incentives: Layer federal credits with state tax credits, utility rebates, and cash incentives — but check how rebates affect the tax credit basis.
- Use tax software or a qualified tax preparer for first-time claims — they can help ensure carryforwards and other limits are handled correctly.
- Track carryforwards: If you can’t use the full credit in year one, maintain a simple spreadsheet showing unused credit amounts and the year of origin.
Frequently asked questions (short)
Q: Do I need to file a special form?
A: Yes — most homeowners use IRS Form 5695 to claim residential energy credits and compute carryforwards.
Q: Can I claim credits for work I did myself?
A: Materials may qualify if they meet IRS product standards, but labor costs may be treated differently depending on the credit. Keep documentation of costs and installation dates.
Q: Are these credits refundable?
A: Residential energy tax credits generally reduce your tax liability dollar-for-dollar; if the credit exceeds your tax owed, many credits allow carryforward but are not refundable (check current IRS rules for specifics).
