Window, Door and Siding Rebates by State in 2026: What Is Left After the Federal Credit Ended

Last reviewed: 2026-09-28

Status as of 28 September 2026: the federal window and door tax credit is gone (see the 25C page). The state-run federal rebates that replaced it in people's minds do not pay for a window, a door or siding on its own. One of the two, HEAR, does not cover them at all. The other, HOMES, can count windows and doors inside a whole-home retrofit, only where a state has launched it and chosen to allow them. Per-window money, where it exists, comes from utilities and state agencies, and its rules differ program by program. This page moves fast; it is next reviewed by 28 October 2026.

Researched and written by one person, not an editorial team. I am an independent researcher, not a licensed contractor, not a tax professional, and I do not install windows, doors or siding. See the About page for exactly what I do and don't do. This page contains no lead-capture form. Nothing here is tax or legal advice; for the federal credit that ended, read the 25C page and consult a tax professional.

The short answer

HEAR (renamed HEEHR) does not cover windows, doors or siding. The statute lists the eligible items, and none is a window, a door or cladding. Details below.
HOMES can count windows and doors, but never as a stand-alone rebate. It pays for a whole-home project that DOE's page says must reach a minimum modeled saving of 20%. Each state decides which upgrades its program allows.
Siding is not named in the statute, DOE's rules, DOE's consumer page or either of the program notices.
Few states are paying HOMES rebates yet. Of the 10 states in the table below, Wisconsin and North Carolina say outright that HOMES has launched, and Michigan describes an operating program without separating HOMES from HEAR. Of those three, only Wisconsin's page says windows, doors and skylights may be included. DOE publishes no state list.
Per-window money is at utility or state-agency level: Mass Save's $75 per window, Energy Trust's $10 per square foot in one Washington service area, and New York's $2,000 Comfort Home windows add-on. Each has conditions that change who actually gets it.

Two federal programs, two different answers

Both programs come from the 2022 Inflation Reduction Act and are run by state energy offices, not by DOE or the IRS. Names have changed, which matters when you search: DOE's Notice 26-2 renames "Home Electrification and Appliance Rebates" (HEAR) as "High-Efficiency Electric Home Rebates" (HEEHR), and Notice 26-1 renames "Home Efficiency Rebates" as "Home Owner Managing Energy Savings" (HOMES). State pages still use both sets of names. (DOE Notice 26-2, DOE Notice 26-1.)

HEAR / HEEHR: windows, doors and siding are not on the list

The statute defines a "qualified electrification project" as one that "includes the purchase and installation of" one of eight things: an electric heat pump water heater, an electric heat pump for space heating and cooling, an electric stove, cooktop, range or oven, an electric heat pump clothes dryer, an electric load service center, insulation, "air sealing and materials to improve ventilation," or electric wiring (42 U.S.C. §18795a(d)(6)). DOE's Program Requirements & Application Instructions repeat the same eight items in Section 4.2.2, and its list of "Qualified Building Materials" is five entries long: electric load service center, electric wiring, insulation, air sealing and mechanical ventilation (DOE, Program Requirements v2.1).

DOE's own consumer page says the same thing in plainer words: "HEEHR can be utilized for insulation, air sealing, ventilation, electric wiring and load service center upgrades, electric heating and cooling upgrades, and efficient electric appliances" (DOE, Home Energy Rebates Program).

A text search of the 106-page requirements PDF finds the word "window" once, in a sentence about a survey timing window. "Door", "doors", "windows", "siding" and "skylight" do not appear as words at all. The two program notices contain none of them either. That search covers the PDF's text layer only, so a table saved as an image would not show up, but it is consistent with the statute.

One more piece of evidence: DOE's Home Upgrades page lists, item by item, what each program may pay for. Insulation and air sealing show "either a High-Efficiency Electric Home Rebate of up to $1,600, or a Home Owner Managing Energy Savings Rebate." Windows and Exterior Doors show only "May be eligible for a Home Owner Managing Energy Savings Rebate" (DOE, Home Upgrades). No electric-home rebate is listed for either. The same page still describes tax credits that have ended; only its rebate entries apply here.

HOMES: windows can count, but they are never the rebate

DOE describes HOMES as providing "rebates for eligible whole-home energy upgrade projects for households at all income levels," with savings "up to $8,000" for "a minimum savings of 20%" (DOE, Home Energy Rebates Program). Its own list of pathways names "insulation, air sealing, heating and cooling equipment, water heaters, duct sealing, appliances, and lighting" and does not name windows. The Home Upgrades page above does.

The requirements document explains why the lists differ. A state that runs the "modeled" path must estimate savings for the whole home, and the estimate must include "at least one major upgrade," defined as "energy usage, equipment, technologies, and services related to heating and cooling, envelope, and water heating end uses." In the state-application checklist, each state has to "identify which upgrades may be included in the modeled savings estimate." So windows are neither listed nor barred by the federal document; the state's application decides (DOE, Program Requirements v2.1, Sections 2.1, 3.2.4.1 and the application checklist).

Two rules change what a window buyer should expect:

ENERGY STAR is required only for some products. The requirements say states must "provide rebates for heating, cooling, and water heating products only if they are certified as meeting the ENERGY STAR product criteria." Windows are not in that sentence. In Notice 26-1, effective 29 May 2026, DOE lists "making the ENERGY STAR requirement optional" among its changes (DOE Notice 26-1). A state can still require ENERGY STAR windows; the federal rules no longer make it do so.
The rebate is capped by the whole project. For a single-family home, the statute's ceiling is the lesser of $2,000 or 50 percent of project cost at 20 to under 35 percent modeled savings, and the lesser of $4,000 or 50 percent at 35 percent or more. For a low- or moderate-income household (under 80 percent of area median income) the ceilings are the lesser of $4,000 or 80 percent, and the lesser of $8,000 or 80 percent. A state energy office may raise the low-income amounts "on approval from the Secretary" (42 U.S.C. §18795(c)).

Whether a window-only project reaches the 20 percent threshold in a home model depends on the house. It is a question for the energy assessor who builds the model.

A worked comparison: the statute and one launched state

Wisconsin's program page shows how a state turns those ceilings into a table. Single-family amounts as published (Focus on Energy, Home Efficiency Rebates):

Household income	20% to 34% modeled savings	35% or more	Statute's default ceiling, same savings tiers
Under 80% of area median income	100% of project cost, up to $5,000	100%, up to $10,000	Lesser of $4,000 or 80%; lesser of $8,000 or 80%
80% to 150%	50%, up to $2,000	50%, up to $4,000	Lesser of $2,000 or 50%; lesser of $4,000 or 50%
Over 150%	50%, up to $1,500	50%, up to $3,000	Lesser of $2,000 or 50%; lesser of $4,000 or 50%

Two things stand out. Wisconsin's lowest-income tier is above the statute's default low-income ceiling, which the statute allows "on approval from the Secretary," and its top tier sits below the statute's general ceiling, which the statute's "shall not exceed" wording allows. The middle tier matches the statute's general ceiling.

Which states have launched

DOE's own page says only that "Home Energy Rebates are now available in select states" and that "additional details on active state, territory or Tribal rebate programs are coming soon" (DOE). There is no federal list to copy. The table below is what each state's own page said on 28 September 2026. It is a sample of 10 states, not a national list. A state missing from the table may still have a program; check your state energy office.

State	HOMES status, quoted from the state	Windows or doors named on that page?
Wisconsin	"Both Home Efficiency Rebates (HOMES) and Home Electrification and Appliance Rebate (HEAR) are NOW AVAILABLE" (Focus on Energy)	Yes: "Select ENERGY STAR appliances, windows, doors, and skylights are also eligible to be included" (Focus on Energy)
North Carolina	"DEQ fully launched both programs in January 2025" (NC DEQ)	No. The page lists "ENERGY STAR appliances, insulation, and more"
Michigan	The MiHER program "provides rebates" and describes HOMES and HEAR pathways; new income-qualified applications are "temporarily unavailable" in five EGLE districts. The page does not give a separate HOMES status (EGLE)	No. HOMES is described as "insulation, air sealing, heating and cooling systems, and other improvements"
Colorado	HEAR single-family "now closed"; Home Efficiency Rebates "available to manufactured/mobile homes and large multifamily buildings in 2026" (Colorado Energy Office)	No
California	"HOMES rebates are not yet available" (CEC)	No
South Carolina	"Rebates are not currently available but are expected to launch in 2026" (SC Energy Office)	Yes, as potential upgrades: "Energy-efficient windows and doors"
Oregon	"Launch delayed while completing key items, awaiting U.S. DOE approval," post of 23 April 2026 (Oregon Dept. of Energy)	No
Washington	Evaluating DOE's notices 26-1 and 26-2 "to determine next steps"; the state's HEAR program is "already up and running" (WA Commerce)	No
Nevada	"Project Launch: Pending federal review and program guidance" (Nevada GOE)	No
Montana	"The Montana Home Energy Rebates Program is not currently available" (Montana DEQ)	No
Missouri	Rebates "may not be made available until 2027 at the earliest and potentially as late as 2028" (Missouri DNR)	No

"No" in the last column means the page did not name them, not that the state excludes them. The South Carolina row matters more than it looks: the page says windows and doors can be part of a project, and says the program is not live. Wisconsin is the only state in the table whose running program says windows, doors and skylights are eligible.

A timing caveat applies to every row. Notice 26-1 says launched programs "are required to make changes within three months of the publication of this Program Notice" and that existing approved rebate reservations "are allowed to be executed, but no new rebate reservations are allowed" for projects that do not conform to the new strategy (DOE Notice 26-1). The notice prints an effective date of 29 May 2026; Washington's page says DOE released the notices on 1 June. Counting three months from either date puts the deadline around the start of September 2026, which has already passed. A state page that has not been updated since could describe rules that no longer apply. Ask the program administrator, not the web page, whether your project is accepted today.

Where the per-window money actually is: utilities and state agencies

Utility and state-agency programs can pay a stated amount for a window. Three examples look alike in the headline number and different in the conditions.

Program	Who qualifies	Amount as published	Product spec	Conditions	Dates on the page
Mass Save (Massachusetts)	Residential electric and gas customers of the listed sponsors	"$75 per window"	"ENERGY STAR Most Efficient certified for the north region," replacing single-pane	Existing windows "verified during a Home Energy Assessment"; customer "must complete weatherization recommendations"	Purchases 1 Jan to 31 Dec 2026; application postmarked or submitted by 28 Feb 2027
Energy Trust of Oregon, windows page	Gas customers of NW Natural in SW Washington	"$10 per sq ft"	"U Value must be 0.30 or less"	Replace single pane (any material) or metal-frame double pane; completed Existing Condition Windows Addendum; apply within 60 days of installation	Not stated on the page
NYSERDA Comfort Home (New York)	Homeowners of one- to four-family homes who pay the System Benefits Charge on their electric bill	"$2,000" Windows Add-On	"upgrade windows to ENERGY STAR"	Add-on comes "after air-sealing and insulating"; "the home must meet conditions of the entire package"	Not stated on the page or the fact sheet

To see what a rate means in practice, take Energy Trust's $10 per square foot. A window 3 feet by 5 feet is 15 square feet, so the published rate works out to $150 for it. That is arithmetic on the posted rate, not a quote. Mass Save's rate is flat per window, so window size does not change it.

Four patterns show up, and they are the reason to read the fine print before you sign a contract.

The spec is not always plain ENERGY STAR. Mass Save requires the stricter "Most Efficient" list for the northern region. Energy Trust writes its own number, a U-value of 0.30 or less, on the same page that says "ENERGY STAR certified windows have a U-Value of 0.27 or lower." ENERGY STAR itself says its window criteria "vary for each of the climate zones" (ENERGY STAR). For what those zone numbers are, see U-factor and SHGC explained.
The old window matters. Mass Save pays only for replacing single-pane windows. Energy Trust pays only for single-pane or metal-frame double-pane. If your existing windows are vinyl double-pane, these two do not apply to you.
Air sealing and insulation come first. Mass Save's specialist may require "air sealing and insulation upgrades" before window incentives; New York's windows add-on is offered only "after air-sealing and insulating." Both programs treat windows as the last step, not the first.
Documents disagree. Energy Trust's Oregon single-family fact sheet, "Effective January 1, 2025," still lists windows at "Up to $1.50 per square foot: Based on efficiency rating" (Energy Trust fact sheet). The current windows page says incentives are "available for SW Washington customers of NW Natural." The two documents disagree, so trust the live page over a PDF, and ask.

How to check your own utility

This is the method behind the three programs above.

List every party that might pay. Your electric utility, your gas utility, and your state energy office. A rebate can be tied to either fuel: Mass Save covers "electric and gas customers," and Energy Trust's window incentive is for gas customers. Co-ops and municipal utilities count too; Montana's page says "Montana electric co-ops often have rebate programs available to their members."
Start with a lookup, and treat it as a lead. ENERGY STAR's Rebate Finder says "Find rebates and special offers near you on ENERGY STAR certified products" and asks you to "enter your zip code to begin." Its product list includes "Residential Windows, Doors and Skylights" and "Storm Windows" (ENERGY STAR Rebate Finder). Results depend on your ZIP code, so confirm anything it shows on the utility's own page.
Open the program's own page and copy down these fields. Use the table below. If you find only a PDF, look for the live page too, as the Energy Trust example shows.
Match a specific window to the spec before you sign. Ask your contractor for the window's NFRC-certified U-factor and its ENERGY STAR climate-zone listing, and compare them with the program's number. Energy Trust wants 0.30 or less. Mass Save wants the Most Efficient list. A window can be ENERGY STAR and still miss both.
Ask about timing before you buy. Mass Save requires verification of the existing windows "prior to installing windows." Wisconsin says "a home energy assessment must be done before any work is started." Washington's page says "we can't issue rebates for any purchases or work done before you're approved." Washington's page says outright that its rebates are not retroactive; ask whether yours are.
Ask about stacking. North Carolina's page says households can receive both state rebates and utility incentives for the same product "however, the combined rebates cannot exceed the purchase-price of the product." DOE's requirements say HOMES may not be combined "with other federal grants or rebates for the same single upgrade." Missouri says its rebates may be combined "with certain other funding sources, such as utility rebates." Rules differ, so ask each administrator.
Write down the deadline and the paperwork. Mass Save's is 28 February 2027 for 2026 purchases. Energy Trust's is 60 days after installation, with a packing slip showing dimensions and proof of the U-value.

Field to record	Example from the programs above	Why it matters
Who is eligible	NW Natural gas customers in SW Washington	A different fuel or service area means no rebate
Existing-window condition	Single-pane, or metal-frame double-pane	A vinyl double-pane replacement may not qualify
Qualifying spec	U-value 0.30 or less; "Most Efficient" list	Decides which products your contractor can quote
What must happen first	Assessment; air sealing and insulation	Mass Save requires the existing windows to be verified before installation
Amount and unit	$75 per window; $10 per sq ft; $2,000 add-on	Per-window, per-area and per-package amounts scale differently
Program dates	Purchases 1 Jan to 31 Dec 2026	Energy Trust's fact sheet says incentives are "subject to funding availability and may change"
Application deadline	60 days after install; 28 Feb 2027	Energy Trust says applications "must be received within 60 days of installation"
Installer rules	Registered contractor; self-install excluded	NC's page says self-installation projects do not qualify

What this means for doors and siding

Doors. DOE's Home Upgrades page says exterior doors "may be eligible for a Home Owner Managing Energy Savings Rebate," and Wisconsin's page names doors as includable. The Mass Save and NYSERDA pages cover windows, not doors. For door prices and material choices, see entry door replacement cost.

Siding. Siding is not named in the statute, DOE's requirements, DOE's consumer page or the state and utility pages above. That does not prove no program exists; a utility or state agency not covered here may offer one. Each state decides which upgrades its HOMES modeled path allows, so ask the program administrator. For the price side, see siding replacement cost.

What we could not verify

Minnesota. The state's program page returned a bot check instead of content on direct fetch (retrieved 2026-09-28). Minnesota is therefore not in the table, and this page makes no claim about whether its program is live. Check the state's own page.
Connecticut. Energize CT's page refused the fetch (retrieved 2026-09-28), so this page gives no Connecticut rebate figure. If you live there, get the current amount and conditions from Energize CT or your utility before you plan around any number you have seen elsewhere.
The ENERGY STAR Rebate Finder results. The finder is a ZIP-code search, and we could not run it for your ZIP code. We quoted only the description on its page (retrieved 2026-09-28). Run it yourself, then confirm anything it shows on the utility's or agency's own page.
The effective date of DOE Notice 26-1. The notice prints an effective date of 29 May 2026; Washington's page says DOE released the notices on 1 June. We did not find anything that settles which date applies, so the three-month window described above is approximate. Ask the program administrator which date they are working from.
Which Energy Trust document is current. Energy Trust's windows page says the incentive is for gas customers of NW Natural in SW Washington. Its Oregon single-family fact sheet, "Effective January 1, 2025," lists windows under a different rate and a different area. Both were retrieved 2026-09-28 and we could not reconcile them. Ask Energy Trust which applies to your address.
Every state not in the table. The table covers 10 states. A state that is missing was not checked. That is not the same as "no program". Your state energy office and your utilities can tell you what exists where you live.
