Rebates vs. Tax Credits in 2026: What Changed After 25C and 25D Ended
Rebates vs tax credits in 2026: the 25C and 25D federal tax credits ended Dec 31, 2025. Here's how rebates differ, what's still available, and how to claim 2025 installs.
Key facts
- A rebate is cash back (or an instant discount) from a program or utility — no tax return involved
- A tax credit reduced the income tax you owed; the federal 25C and 25D credits ended December 31, 2025
- 2025 installs can still be claimed on your 2025 return (IRS Form 5695); unused 25D credit generally carries forward
- In 2026 the main federal savings are IRA rebates (HOMES/HEAR), plus utility rebates and weatherization
Why the distinction suddenly matters
Through 2025, homeowners could combine rebates with the 25C/25D federal tax credits. The One Big Beautiful Bill Act (July 2025) terminated both credits for property placed in service after December 31, 2025 — so for a 2026 project, tax credits contribute $0 and rebates carry the whole load. That changes which projects pencil out; our calculator already reflects it.
How each mechanism works
| Feature | Rebate | Tax credit (ended) |
|---|---|---|
| When you get money | At purchase or weeks after applying | At tax filing, the following year |
| Depends on tax owed? | No | Yes — nonrefundable |
| Income limits | Sometimes (HEAR: ≤150% AMI) | No |
| Where to claim | Program portal / contractor / retailer | IRS Form 5695 |
| Status in 2026 | Active — IRA + utility programs | Ended for new installs |
Still claiming a 2025 install?
If your equipment was placed in service by December 31, 2025, you can claim 25C (up to $1,200/year; $2,000 for heat pumps) or 25D (30%, no cap) on your 2025 return. Keep the manufacturer certification and itemized invoice. Unused 25D credit generally carries forward to future years. This is not tax advice — confirm with the IRS or a tax professional.
