Budget 2026 Energy Upgrades Without Expired Federal Credits
For new 2026 installations, budget $0 from federal homeowner credits 25C and 25D. Section 25C ended for property placed in service after December 31, 2025; section 25D ended for expenditures after that date. For 25D, installation completion determines when installation costs are treated as spent. Paying in 2025 for work completed in 2026 does not preserve the credit. Review eligible work completed in 2025 separately with your tax preparer.
Decision framework
- Start with an itemized installation quote before incentives. Separate equipment, labor, electrical work and permits.
- Use $0 for federal 25C and 25D credits on a new 2026 installation; do not schedule future work around their former annual caps.
- Check the current state and utility program for your address, income, equipment and installation date before counting a rebate.
- Confirm reservation, preapproval and contractor requirements before signing. Do not assume programs can be combined.
- Keep installation-completion records, invoices and product documentation. Ask your tax preparer about qualifying 2025 work and any eligible carryforward.
Separate 2025 Eligibility From New 2026 Work
| Project timing | Federal 25C | Federal 25D | Budget action |
|---|---|---|---|
| Qualifying work completed in 2025 | Review 2025 rules | Review 2025 rules | Keep records; confirm eligibility |
| New installation completed in 2026 | $0 | $0 | Budget before confirmed local rebates |
| New work split across 2026 and 2027 | No renewed annual cap | No renewed credit | Choose timing for the home and budget |
This table describes new work and does not determine an individual's tax return or treatment of a previously earned carryforward.
A budget that does not depend on an expired credit
Start with the written installed cost. Subtract only incentives for which the current program confirms eligibility. Estimate operating savings separately; savings arrive over time and do not pay the installation invoice.
Review 2025 records separately
The end of credits for new work does not mean eligible 2025 work should be ignored. Keep completion dates, itemized invoices and product records for a tax-preparer review. Do not apply 2025 caps or percentages to a new 2026 installation.
Check local program rules before signing
State and utility offers differ by location and can change as funding is used. Confirm preapproval, qualifying equipment, installer requirements and whether offers can be combined. An advertised maximum is not a guaranteed payment.
Pitfalls to avoid
- Subtracting expired federal credits from a new 2026 project budget.
- Treating a 2025 deposit as proof that a 2026 installation qualifies for 25D.
- Counting a local rebate before confirming address, income, equipment, funding and contractor eligibility.
- Assuming a tax credit, rebate, financing offer and utility bill savings are the same kind of benefit.
Common questions
Can I claim 25C or 25D for a new 2026 installation?
No. Federal 25C does not apply to property placed in service after December 31, 2025. Federal 25D does not apply to expenditures after that date; installation costs are treated as spent when installation is completed.
Can I still review work completed in 2025?
Yes. Eligible 2025 work may qualify on the appropriate tax return, subject to the rules and limits for that work. Use the IRS instructions and review your records with your tax preparer.
Does paying a solar deposit in 2025 preserve 25D for a 2026 installation?
No. The IRS treats installation costs as expenditures when the original installation is completed. Prepaying alone does not preserve eligibility.
What help may remain for 2026 projects?
State, utility and other local offers may remain available. Amounts, funding, income rules and eligible equipment vary. Confirm the current program terms before counting an incentive.
