Here's something almost nobody tells you when you close on a house: the homestead exemption, the federal energy rebates, and your utility company's appliance rebates are all run by different agencies. They don't talk to each other. They don't cancel each other out. You can claim all of them.
Most people find one — usually the homestead exemption, maybe a utility rebate — and assume that's it. But stacking all the available layers can be worth $10,000 to $20,000 or more, depending on where you live and what upgrades you're doing.
The U.S. Treasury published an explainer confirming that federal energy tax credits and DOE rebates are designed to work together. The Department of Energy says the same thing. This isn't a loophole — it's how the programs were built.
Here's the full stack, layer by layer.
Layer 1: Homestead exemption (property tax, every year)
This is the foundation. If you own your primary residence and haven't filed for a homestead exemption, you're overpaying on property taxes right now.
In Texas, the school district exemption alone knocks $140,000 off your assessed value. On a $350,000 home, that can save you roughly $3,500 per year — and it renews automatically once you file. Source: Texas Comptroller.
Florida's exemption is $50,000 off. Georgia varies by county. Almost every state has some version of this. You file a form once with your county assessor's office. Ten minutes. Done.
The homestead exemption is a property tax program run by your county. It has absolutely nothing to do with your federal income taxes, your utility company, or any energy rebate. That's why it stacks with everything else.
Layer 2: HOMES and HEAR rebates (federal, point-of-sale)
These are the big ones from the Inflation Reduction Act, and they're live in most states right now.
HOMES rebates (Home Owner Managing Energy Savings) cover whole-home efficiency projects. If your upgrades save 20%+ on energy use, you could receive up to $8,000 back. Income-qualified households can receive up to $16,000. You apply through your state energy office — not the IRS.
HEAR rebates (Home Electrification and Appliance Rebates) are for specific electrification upgrades: heat pumps, electric stoves, breaker panels, insulation, wiring. The per-household cap is up to $14,000. These are applied as point-of-sale discounts, meaning the price drops before you pay.
Both programs are funded through 2031, but each state got a fixed allocation. When it's gone, it's gone. Source: DOE.
On top of the rebates, you can also claim the Energy Efficient Home Improvement Credit (25C) on your federal tax return — up to $3,200 per year for qualifying equipment and materials. Source: IRS. The Treasury has explicitly stated that the 25C tax credit and the DOE rebates can be combined, as long as you're not getting reimbursed for the same dollar twice.
Layer 3: Utility rebates (local, per-appliance)
Your electric or gas utility almost certainly has its own rebate program. These are completely separate from everything above — funded by the utility, administered by the utility, with their own application forms.
Typical utility rebates run $200 to $3,000 per appliance. Common ones include:
- Smart thermostat: $50–$150
- Heat pump water heater: $300–$1,000
- Central heat pump: $500–$3,000
- Insulation and air sealing: $200–$800
- Energy Star appliances: $50–$300
These rebates don't reduce your eligibility for HOMES, HEAR, or 25C. Different pot of money, different organization. You just submit a separate application (usually on your utility's website with a receipt and model number).
The math: a real Texas example
Say you own a $350,000 home in Texas and you're planning to replace your aging AC with a heat pump and upgrade your water heater. Here's what the stack could look like:
| Program | Source | Estimated value |
|---|---|---|
| Homestead exemption | County assessor | ~$3,500/year (ongoing) |
| HOMES rebate | State energy office | Up to $8,000 (one-time) |
| HEAR rebate (heat pump) | State energy office | Up to $8,000 (one-time) |
| 25C tax credit | IRS / tax return | Up to $2,000 (per year) |
| Utility rebate (heat pump + water heater) | Your utility | $500–$2,000 (one-time) |
Conservative total: $12,000–$15,000+ in the first year alone, plus $3,500/year in ongoing property tax savings.
And none of these programs required you to choose one over the other. You just had to know they all existed and file four separate applications.
Why nobody tells you this
The reason the stack is invisible is structural. Your county assessor handles property taxes. Your state energy office handles HOMES and HEAR. The IRS handles 25C. Your utility handles its own rebates. None of these agencies are going to mention the others because it's not their program.
Your accountant only sees your tax return. Your real estate agent stopped thinking about you after closing. Your utility sends rebate info buried in a bill insert you threw away.
So you end up finding one program, feeling good about it, and missing three others.
Where to start
If you haven't filed your homestead exemption yet, do that first. It takes 10 minutes and the savings are ongoing. Then check what your utility offers — most have a rebate page you can find by searching "[your utility name] rebates." For HOMES and HEAR, check your state energy office website to see if applications are open.
