How to stack rebates and incentives in 2026, in the right order.
Most pages ranking for this question still tell you to put the 30% federal tax credit on top. That advice is wrong for anything installed in 2026. Here is what actually stacks now, what does not, and the order that keeps the money on the table.
The federal credit is not part of your stack anymore
Start here, because almost every stacking guide online is built on a layer that no longer exists.
The 25C Energy Efficient Home Improvement Credit was terminated for property placed in service after December 31, 2025, under the One Big Beautiful Bill Act (OBBB, Public Law 119-21, signed July 4, 2025). It originally ran through 2032 under the Inflation Reduction Act; OBBB pulled the sunset forward by seven years. The residential clean energy credit, 25D, ended the same way, for expenditures made after December 31, 2025. It matters here only because homeowners routinely mix the two up, and because geothermal heat pumps were 25D's one HVAC-adjacent measure.
The date that decides your case is the placed-in-service date, meaning installed and operational, not the date you bought the equipment and not the date you signed the contract. Equipment purchased in 2025 and installed in 2026 does not qualify. This trips people up constantly, because a fall 2025 purchase with a spring 2026 install feels like a 2025 project. To the IRS it is not.
One thing is still claimable in 2026: a system placed in service on or before December 31, 2025 is claimed on the 2025 return, filed in 2026, using IRS Form 5695. That is the last filing season for it. If that is your situation, the mechanics are in the Form 5695 walkthrough.
25C was worth up to $2,000 a year on a qualifying heat pump or heat pump water heater, and 30% of cost up to $1,200 a year on envelope work such as insulation, air sealing, and energy assessments. Those numbers describe what the credit paid before it expired. They are not available for a 2026 install. If a contractor's proposal, an ad, or a competing guide quotes them in the present tense, that page or that salesperson has not been updated, and every total built on top of them is wrong by up to $2,000.
Say it plainly: any stacking plan that includes "the federal credit" is a 2025 plan. If you are planning a project now, delete that line and rebuild the stack out of what is left. The full detail on the expiration is in the heat pump tax credit expired.
What actually stacks in 2026
Three layers, in this order. The first is the one you can count on almost anywhere. The third is not a rebate at all, and copy that blurs the difference is doing you a disservice.
State and utility ratepayer-funded rebates
What it is The programs your efficiency utility or state energy office runs, paid for out of ratepayer funds rather than federal appropriations. Mass Save, Efficiency Maine, Focus on Energy, NHSaves, and your local utility's HVAC rebate all live here.
Why it matters now This is the primary lever in 2026. These programs do not depend on the federal tax code, so nothing that happened in Washington last year changed them. They are also the only layer that exists in essentially every state in some form.
The catch Amounts, deadlines, and contractor requirements are set locally and change without much notice. A rebate that existed in March may be exhausted in October.
HEAR and HOMES, where a state has actually launched
What it is The two IRA-funded federal rebate programs, delivered by states. HEAR (Home Electrification and Appliance Rebates) pays per measure; HOMES (Home Efficiency Rebates) pays for whole-house modeled or measured savings.
Why it matters now Where these are live, they are the largest single pot on the table: HEAR is designed to go up to $14,000 per household, income-tiered, and HOMES up to $8,000 per household for projects hitting at least 20% energy savings (DOE program page, verified July 15, 2026).
The catch A federal allocation is not a rebate. Every state got money. Only some states have a program a homeowner can apply to, and several of those are income-restricted, waitlisted, or partly closed. Section 03 has the picture.
Low-interest financing
What it is State energy loans, green bank loans, and utility on-bill programs. Massachusetts, Maine, Connecticut, New Jersey, Pennsylvania, Delaware, Nebraska, Vermont, and some individual utilities run them.
Why it matters now Cheap money reduces what the project costs you over its life, and it lets you do work now instead of waiting to save cash. Applied on top of rebates, it covers the remainder.
The catch This is not a rebate. It is money you pay back. Any page that adds a loan amount to a rebate total and calls the sum your incentives is misleading you. Keep the two in separate columns.
The practical consequence of losing the federal tax layer is that layer one now carries the weight it used to share. In a state with strong ratepayer programs, that is survivable. In a state with weak ones, the gap gets filled by layer three, which means the project costs more over its life even if the sticker price is the same. The lending programs worth knowing about, with verified rates and caps, are in state energy efficiency loans.
Keep the columns separate when you do your own math. Rebates are money you keep. Loans are money you return with interest. A quote that presents "up to $22,000 in incentives and financing" is adding two different kinds of number together, and the total means nothing.
Every state got money. Only some states have a program you can apply to.
This is the single most common error in HEAR and HOMES coverage: quoting a national design cap as though it were a rebate available in your ZIP code. It is not.
The federal design caps are real and worth knowing: HEAR goes up to $14,000 per household, income-tiered, with per-measure caps of $8,000 for a heat pump, $4,000 for an electrical panel, $2,500 for wiring, $1,750 for a heat pump water heater, and $1,600 for insulation, air sealing, and ventilation together. HOMES is designed to go up to $8,000 per household for projects achieving at least 20% energy savings, per DOE's program page (verified July 15, 2026). A handful of states, North Carolina and Georgia among them, received DOE approval for a higher HOMES cap of $16,000.
None of that is a promise to you. For money to reach a homeowner, the state has to file a State Implementation Blueprint, get DOE approval, then stand up and launch its own program. Plenty of states hold a large allocation and have no consumer program at all. Here is the picture as of our last verification, with the check date on every row.

| Colorado | HEAR launched but partially closed | Single-family intake is split by region and Region 1 (the Front Range) is closed. HOMES is launching in 2026 for a limited set of home types. | 2026-07-11 |
| California | HEAR active but effectively closed to new single-family applicants | Administered by the CEC through TECH Clean California. Single-family funds have been fully reserved statewide since February 24, 2026, waitlist only, and multifamily applications are paused. HOMES not launched to consumers. | 2026-07-15 |
| Maine | HEAR active but highly restricted | Limited to new-construction affordable multifamily and to income-eligible single-family mobile and manufactured homes (the $12,900 Mobile Home Initiative). Standard single-family homeowners are not eligible. HOMES not launched. Flagged provisional pending the state's response to Program Notices 26-1 and 26-2. | 2026-07-15 |
| District of Columbia | HEAR launched but income-restricted | Delivered only through the Affordable Home Electrification program. | 2026-07-11 |
Not launched as of the same sweep: Connecticut, Massachusetts (administrator-confirmed, to be delivered through Mass Save's income-eligible channel), Vermont (funding in question), New Jersey, Pennsylvania, Maryland, Illinois, Ohio, Iowa, Minnesota, Missouri, Kansas, Nebraska, North Dakota, Montana, Utah, Nevada, Oregon (under a DOE approval suspension), Washington, Texas, Oklahoma, Louisiana, Mississippi, Tennessee, South Carolina, Virginia, Kentucky, Florida, and Hawaii. Florida is pre-launch and active, not dead.
Two other changes reshape what these programs cover, both from DOE program notices dated May 29, 2026 and verified July 15, 2026. Under Program Notice 26-2, HEAR no longer covers fuel switching: heat pumps and electric appliances qualify only for new construction or for replacing existing electric equipment, not for replacing a gas, oil, or propane appliance. The same notice requires insulation and air sealing upgrades before appliance rebates. Program Notice 26-1 restarts HOMES under matching rules after the post-January-2025 funding freeze and the litigation that restored funds in March 2025. States already paying under the old rules have roughly three months to amend, putting that window around the end of August or early September 2026.
What this means for a stacking plan: do not put a HEAR dollar figure into your budget on the strength of a national table. Check the launch status for your own state at your state page, and if you heat with fossil fuel, check the amended rules before you assume the heat pump line survives. The current federal rebate picture in full is in home energy rebates in 2026.
HEAR and HOMES usually do not combine on the same measure
People assume the two federal pots add together. In launched states, they generally do not, at least not on the same piece of equipment.
Take North Carolina, one of the few states where both programs are live and operational. Energy Saver North Carolina, run by the NC DEQ State Energy Office, states that HEAR and HOMES cannot be combined for the same technology upgrade (verified July 11, 2026). One heat pump gets one federal program's money. Not both. Wisconsin's Focus on Energy portal carries the same restriction alongside its note that the federal money stacks with Focus on Energy's own ratepayer rebates (verified July 11, 2026).
That second half is the part worth holding onto. The restriction is between the two federal programs, not between federal and state. Ratepayer-funded state and utility rebates are a different layer with a different funding source, and in launched states they are frequently designed to sit on top. So the realistic best case on a single measure is one federal program plus the state or utility rebate, not two federal programs plus the state.
Stacking rules are program-specific and set by each state, not by the federal statute. Two states with identical allocations can write opposite rules. Where a split is allowed, the usable shape is often HEAR on a specific appliance and HOMES on the whole-house retrofit performance, treated as separate scopes with separate paperwork. Where it is not allowed, you pick the larger one. "Check your state program's own stacking rules" is not a dodge, it is the only accurate instruction anyone can give in prose.
Three questions get you a real answer from an administrator, and they are worth asking before you sign anything. First: can this measure take both HEAR and HOMES, or do I have to choose. Second: is your rebate calculated on the project cost before or after other incentives are applied. Third: do you exclude equipment that has already received money from another program. The answers change the total, sometimes by thousands.
The Rebate Matcher does the state-level lookup that a general guide cannot, including launch status, so you are checking one state's rules rather than reading around fifty.
Phasing captures more cycles, and risks more expiration
The multi-year question is not just which programs combine. It is whether splitting the work across calendar years wins you a second bite or costs you the first one.
Start with the mechanic that makes phasing attractive. HEAR caps are per measure, not per year: the $1,600 insulation, air sealing, and ventilation cap and the $8,000 heat pump cap are separate line items inside one $14,000 household lifetime cap, so doing them in different years does not multiply them. State and utility programs work differently. Many reset on an annual program year, which means a household that does envelope work in one cycle and heating equipment in the next can draw on two funding cycles rather than one. That is the real argument for phasing, and on a large project it is worth money.
Now the argument against, which is just as real. A program that exists this year may not exist next year, and waiting is a bet on an administrator's budget you cannot see. Efficiency Maine's insulation and air sealing rebate program carries a hard completion deadline of September 30, 2026 (verified July 15, 2026): the work has to be finished on or before that date under current program terms, and the terms that apply afterward have not been published. A Maine homeowner who decided to defer insulation to a later phase is not deferring into a known program, they are deferring into an unknown one.
The same risk shows up in a softer form as funding exhaustion. Programs that run first-come, first-served can close mid-year without changing a published deadline at all, and the phrase "while funds are available" appears in more program terms than most homeowners notice. California's HEAR single-family funds have been fully reserved statewide since February 24, 2026, waitlist only (verified July 15, 2026). Colorado's Front Range region is closed to new single-family HEAR applications (verified July 11, 2026). Neither of those was announced a year in advance.
Your state or utility rebates reset annually and the total project would blow past a single-year cap. Contractor lead times are long enough that one season cannot hold the whole scope anyway. Cash flow, not eligibility, is the binding constraint. And the earlier phase makes the later one smaller, which envelope work almost always does.
A named deadline sits between your phases, like Maine's September 30, 2026 insulation completion date. The program says "while funds are available." Your state is mid-amendment under the DOE notices, so the rules you are planning against may not survive the phase gap. Or the measure you are deferring is the one currently paying the most.
The rule we would give a homeowner: take the money that has a published end date first, and defer the measure whose program looks most stable. That usually inverts the naive plan, which defers whatever feels least urgent. Deadlines, not urgency, should set the order. For the technical sequence underneath the money, see retrofit sequencing and the whole-home electrification plan.
A multi-year plan needs a claims calendar, not just an install calendar
The most preventable way to lose a stacked rebate is to earn it and then miss the window to claim it.
Most rebate programs run two clocks. One is the calendar deadline everybody talks about, the date by which work must be installed or completed. The other is a rolling clock that starts the day your job finishes and expires on its own schedule. Miss the second one and the rebate is gone even though you did everything else right and on time. These are a few of the rolling windows we track.
Energy Trust of Oregon requires the application and supporting documents within 60 days of initial installation for every residential measure (heat pump, water heater, insulation, thermostat) or the incentive is forfeited. Verified July 11, 2026.
Efficiency Maine requires the claim form to be emailed or postmarked within 6 months of project completion. The mail-in heat pump water heater rebate runs 6 months from purchase instead. Applies to every Efficiency Maine residential rebate. Verified July 15, 2026.
NV Energy PowerShift weatherization requires rebate documents to be received within 180 days of project completion. Verified July 11, 2026.
Notice how far apart those three sit: 60 days, 6 months, 180 days. On a phased project touching more than one program, you can easily be holding three different clocks at once, started on three different dates. That is why a stacking plan needs a claims calendar as well as an install calendar. Write down, for each measure, the date the work completes, the claim deadline that follows from it, and who is responsible for filing (in several programs the contractor files, not you, which is worth confirming in writing rather than assuming).
Two other paperwork traps are worth naming. Some programs require pre-approval or a pre-install energy assessment, which cannot be done after the fact at all, so a stacked plan can be disqualified before the first tool comes out. And some programs require a registered, participating, or trade-ally contractor, which means the installer you pick in phase one may quietly determine which rebates phase two can reach. Ask about both before you sign the first contract.
The step-by-step version, including what documentation each type of program asks for, is in how to apply for rebates after installation.
Three phases in a launched-HEAR state, hypothetical
This is an illustration, not a quote. The household, the state, and the numbers are constructed to show how the caps interact. Your own state's rules govern.
Assume a household in a state where HEAR has actually launched and is open to single-family applicants, with income below 80% of area median income. The income tiers matter to every number below. Under HEAR, a household under 80% AMI can have 100% of project cost covered up to the per-measure caps. A household between 80% and 150% AMI gets 50% of cost against the same caps. Above 150% AMI, a household is generally not eligible for HEAR at all, which is why this example specifies the tier before it specifies a dollar.
Assume also that the household currently has electric heat, because under Program Notice 26-2 that is now what makes the appliance phases eligible. The plan runs in three phases across more than one program year.
Air sealing and insulation
HEAR per-measure cap covering insulation, air sealing, and ventilation together.
This goes first for three reasons. It is the work that makes every later measure smaller and cheaper. It is the measure whose cost an income-eligible household is most likely to see covered outright. And under DOE Program Notice 26-2 it is now a prerequisite: insulation and air sealing upgrades are required before appliance rebates. On top of the HEAR money, the household claims whatever the state or utility envelope rebate pays, which is a separate program with its own form and its own deadline.
Heat pump
HEAR per-measure cap for a heat pump.
A tighter, better-insulated house needs a smaller system, so doing this second lowers the bill it is applied against. The eligibility catch is the one everybody misses: under Program Notice 26-2, HEAR no longer covers fuel switching. A heat pump qualifies for new construction or for replacing existing electric equipment. If this household heats with gas, oil, or propane, the HEAR heat pump rebate does not cover the conversion, and the state or utility rebate becomes the only heat pump money in the plan.
Heat pump water heater
HEAR per-measure cap for a heat pump water heater.
Last, because a water heater rarely blocks anything else and because it is the smallest number in the plan. The same replacing-existing-electric rule applies. Note what has happened to the household total: $1,600 plus $8,000 plus $1,750 is $11,350, still under the $14,000 household cap, with room left for a panel or wiring measure if the electrical work turns out to need it.
Two things this example is deliberately not doing. It is not adding a federal tax credit, because there is not one to add for a 2026 install. And it is not adding HOMES on top of HEAR for the same measure, because in the launched states we have checked that is not allowed. What it does add, at every phase, is the state or utility rebate, which is a separate program on a separate funding source with its own form, its own contractor requirements, and its own claim clock.
The envelope-first ordering used to be a recommendation from good contractors. Under Program Notice 26-2 it is a condition of the money, since insulation and air sealing upgrades are now required before appliance rebates. That happens to be the right technical order too: sealing and insulating first shrinks the heating load, which shrinks the equipment, which shrinks the bill the later rebates are applied against. The reasoning is in weatherize before the heat pump, and the equipment side is in our heat pump hub.
Your stack depends on one state's rules, not fifty.

Run the Rebate MatcherRebate stacking questions
Can I still claim the federal heat pump tax credit in 2026?
No, not for a 2026 install. The 25C Energy Efficient Home Improvement Credit was terminated for property placed in service after December 31, 2025, under the One Big Beautiful Bill Act (Public Law 119-21, signed July 4, 2025). The IRS uses the placed-in-service date, meaning installed and operational, so equipment you bought in 2025 but had installed in 2026 does not qualify. A system placed in service on or before December 31, 2025 is still claimed on the 2025 return, filed in 2026, on IRS Form 5695. That is the last filing season for it. The residential clean energy credit (25D) ended the same way, for expenditures made after December 31, 2025.
Can I combine HEAR and HOMES on the same project?
Usually not on the same measure. North Carolina's launched program, Energy Saver North Carolina, states plainly that HEAR and HOMES cannot be combined for the same technology upgrade (verified July 11, 2026), and that is the common pattern. What can sometimes work is HEAR on a specific appliance and HOMES on the whole-house retrofit performance, treated as separate scopes. The rule is set by each state, not by the federal statute, so the honest instruction is to read your own program's stacking rules before you assume anything.
Do rebates reduce each other?
Sometimes, and the mechanism matters. Many programs cap a rebate at a percentage of the eligible project cost, so if one rebate lands first and lowers the cost the next program looks at, the second rebate shrinks. Others explicitly bar a measure that is already receiving an incentive from another program. Others stack freely. Ask each administrator two questions: is your rebate calculated on the price before or after other incentives, and do you exclude equipment that received another program's money. Get the answer before the install, because the order the paperwork is filed in can change the total.
What happens if my state has not launched HEAR yet?
You do not have a federal rebate to stack, and you should not build a budget around one. As of the verified dates in section 03, states including Connecticut, Massachusetts, Vermont, New Jersey, Pennsylvania, Maryland, Illinois, Ohio, Minnesota, Texas, Oregon, and Washington had not launched a consumer program. That does not leave you empty-handed. State and utility ratepayer-funded rebates run independently of the federal programs, and in a not-launched state they are the entire stack. Start at your state page and the Rebate Matcher rather than waiting on a launch date nobody has published.
Do rebates apply if I already installed the equipment?
Only if you are still inside the program's claim window, and those windows are short. Energy Trust of Oregon gives you 60 days from installation. Efficiency Maine gives you 6 months from project completion. NV Energy's weatherization rebates give you 180 days. Several programs also require pre-approval or a pre-install energy assessment, which cannot be done retroactively at all. If you have already installed, check the claim deadline today rather than at tax time, and read our guide on applying for rebates after installation.
Does taking a 0% state loan disqualify me from a rebate?
Generally no. Rebates attach to the equipment, the contractor, and the household, not to how you paid the invoice. Several state loan programs are deliberately built to work alongside the same state's rebates. What does change is the sequencing: a rebate applied at the point of sale reduces the amount you finance, while a rebate that arrives as a check months later means you borrowed the full price and paid interest on money you eventually get back. Confirm both programs' rules before you sign the loan, not after.
