If you’re thinking about installing a tankless water heater in 2026, there are still ways to save money, but the rules have changed. The federal 25C tax credit for qualifying water heaters ended on December 31, 2025, so you shouldn’t expect a federal incentive for a new tankless water heater installed this year.
That doesn’t mean tax rebates are gone. Some states, local programs, and utility companies still offer incentives for qualifying tankless water heaters, particularly high-efficiency gas models. The amount you can get, which models qualify, and whether you need to meet specific installation requirements can vary quite a bit.
The easiest way to find out what’s available is to check your ZIP code and utility provider before buying a water heater. A model that qualifies for a rebate in one area may not qualify in another, so it’s worth checking the current program requirements first.
Tankless Water Heater Rebates In 2026
You may still qualify for a tankless water heater rebate, but things have changed since last year. The federal Energy Efficient Home Improvement Credit ended for qualifying improvements placed in service after December 31, 2025. For a new installation in 2026, the incentives available to you will mainly depend on where you live, your utility company, and the specific tankless water heater you choose.
These programs aren’t all the same. Each one comes with its own set of rules and requirements, so it’s worth taking the time to find the one that fits your situation. And if things start to get a little murky, don’t hesitate to bring in your TAX CONSULTANT. They’ll help you sort through the fine print and make sure you’re getting everything you’re entitled to.
However, it’s not as complicated as it might seem at first. When I applied for the first time, I felt overwhelmed too. But once I got the hang of the process and understood the details, I quickly saw just how worthwhile it really is.
So, let’s get into the good stuff—REBATES available in 2026. Tankless (or on-demand) water heaters may qualify for tax credits under the following programs:
Federal Income Tax Rebates
There isn’t a single nationwide rebate amount for tankless water heaters in 2026. Instead, available incentives depend on your state, local programs, utility company, and the water heater you install.
Some utility programs offer incentives for qualifying high-efficiency tankless water heaters, with gas models appearing in several current 2026 programs. The amount and requirements can vary widely, so you’ll need to check the program available in your area.
Before buying a unit, check your ZIP code and utility provider for current offers. Also make sure the specific model you’re considering meets the program’s requirements. Some rebates are limited to certain efficiency ratings, ENERGY STAR-certified models, or approved equipment.
There’s no standard $600 federal benefit to claim anymore. Your actual savings will depend on the local utility rebate programs available where you live.

State and Local Tankless Water Heater Rebates
Depending on where you live, you might be eligible for state-level or local tax credits and utility company rebates that can make your tankless water heater upgrade even more affordable.
State Incentives
With the federal 25C credit no longer available for 2026 installations, state and local programs are more important to check. They vary quite a bit depending on your location. The eligibility requirements, reimbursement amounts, and qualifying equipment standards can all differ.
The best place to start? Your State Energy Office. They can point you to the most up-to-date and relevant programs for your area.
Utility Company Rebates
It’s not just the government offering incentives—local utility companies often pitch in as well. Many gas and electric providers offer incentives when you install a high-efficiency tankless water heater, and in some cases, the savings apply at the time of purchase or installation, giving you instant financial relief.
Just like with state programs, these incentives come with their OWN requirements. You may need to:
Use a licensed contractor for the installation.
Choose a specific model that meets the utility provider’s energy efficiency standards.
Submit documentation within a certain timeframe.
In Southern California, the local natural gas utility offers rebates for eligible tankless models—but only if you hire a licensed contractor and select a unit that meets their published efficiency specs.
| Provider/program | Equipment | 2026 availability |
|---|---|---|
| Avista Utilities | Tankless gas water heater | Jan. 1–Dec. 31, 2026 |
| PECO | Tankless gas water heater | Jan. 1–Dec. 31, 2026 |
| Cascade Natural Gas | Tankless gas water heater | Mar. 15, 2026–Mar. 14, 2028 |
| New Mexico Gas Company | Tankless gas water heater | Apr. 1, 2026–Apr. 30, 2027 |
These are examples, not nationwide offers. Eligibility, rebate amounts, qualifying models, and installation requirements vary by utility.
Stay Up To Date
Rebate programs can change from year to year, sometimes even mid-year. To avoid missing out, I recommend checking the websites of your state’s energy department and your local utility provider for the latest details on:
- Deadlines and paperwork
- Available programs
- Approved products
Which Water Heaters Are Eligible For The Tax Credit?
As you might’ve noticed, I’ve mentioned a couple of times that only certain high-efficiency tankless water heaters qualify for tax rebates. So, the natural next question is: which models actually qualify?
ENERGY STAR Certification Still Matters
Some programs require specific efficiency ratings, ENERGY STAR certification, or particular models. Don’t assume that meeting one program’s UEF requirement guarantees eligibility for another.
Also, it’s important to point out: only brand-new units qualify. That means the water heating unit must be newly purchased and installed—previously used or secondhand models don’t count toward the rebate.
A qualifying model may be eligible for a rebate in one utility service area but not another. For example, current 2026 programs listed by ENERGY STAR include incentives of $1,000 from Cascade Natural Gas and $300 from CenterPoint Energy in Indiana for qualifying tankless gas water heaters.
For 2026, don’t rely on older articles listing the federal 25C credit. Check your ZIP code in ENERGY STAR’s Rebate Finder and then verify the offer directly with your utility before buying the water heater.
How To Find and Claim a 2026 Tankless Water Heater Rebate
Let’s be honest—this part can feel a little overwhelming. Once your brand-new tankless water heater is up and running, figuring out how to actually claim the tax credit is where things get tricky. But before we jump into the steps, let’s quickly review the eligibility criteria, so you can be sure you qualify.
Check These Requirements First
To qualify for the Energy Efficient Home Improvement Credit, homeowners (or tenants, in some cases) need to meet the following conditions:
Installed In A U.S. Residence: You should install the tankless water heater in your existing residence that is in the USA; it cannot be a home you have newly developed. This can include your secondary home, as well as rental properties where the taxpaying tenant carries out eligible high-efficiency home improvements.
Energy Star Rating: As we have already discussed, the tankless model must be Energy Star certified and be equal to or higher than the specified UEF value.
Home Energy Audits: Some state or utility programs may offer incentives for home energy audits, but these are separate from the expired federal 25C credit.
However, your home must be located in the USA and be your PRIMARY residence. If you have a second home, it will not qualify for tax benefits, but taxpaying tenants might be eligible if they carry out eligible energy upgrades.
For state and utility-level incentives, I recommend visiting the respective official websites for the latest guidelines, as these can vary widely from place to place and are often updated periodically. I would say this is the best way to ensure we do not overlook any clauses and can derive the maximum tax benefits.
How To Claim a Local or Utility Rebate
If you’re buying a tankless water heater in 2026, don’t overlook the rebates available through your state, local government, or utility company. These programs can help bring down the upfront cost, but the rules aren’t the same everywhere.
Start by checking with your state energy office and local utility provider. You can also use a database such as ENERGY STAR’s Rebate Finder to see what programs are available in your area. I recommend doing this before you buy the water heater, because some programs have specific equipment requirements or require pre-approval.
1. Find Your Local Rebate Program
Enter your ZIP code into the available rebate tools or check your utility company’s website. Look for programs that specifically cover tankless water heaters and check whether they apply to gas, electric, or both.
2. Check the Qualifying Equipment List
Don’t assume that any ENERGY STAR-certified tankless water heater will qualify. Some programs have their own list of eligible models or require a particular efficiency rating. Check the exact model number before making your purchase.
Models such as the Rinnai RU199iN, Rinnai RX199iN, Navien NPE-240A2, Noritz NRCR92DV, and Bosch Greentherm 9000 are examples of high-efficiency gas tankless water heaters you may come across when comparing qualifying equipment. Whether a particular model qualifies depends on the rebate program in your area.
3. Confirm the Installation Requirements
Read the fine print before scheduling the installation. Some programs require the work to be completed by a licensed or approved contractor, while others may have requirements for installation, efficiency, fuel type, or the existing water heater being replaced.
4. Check Whether Pre-Approval Is Required
This is one step you don’t want to skip. Some incentives require you to apply or receive approval before purchasing or installing the equipment. If you install the unit first, you could potentially make yourself ineligible for the rebate.
5. Install the Qualifying Water Heater
Once you’ve confirmed the requirements, have the tankless water heater installed according to the program’s rules. If an approved contractor is required, make sure you use one who meets the program’s requirements.
6. Keep All Your Documents
Save your proof of purchase, itemized invoice, installation receipt, model number, serial number, and contractor information. Some programs may also ask for photos, proof of payment, or documentation showing that the old water heater was removed.
I’d keep these records even after submitting the rebate. If there’s a problem with the application later, having everything in one place makes it much easier to sort out.
7. Submit the Rebate Application
Complete the application through the utility, state program, or local agency before the stated deadline. Double-check that the model number, installation date, purchase price, and other information match your supporting documents.
8. Keep a Copy of Your Submission
After submitting the application, save a copy of the application, confirmation email, receipts, and any other documents you provided. Those programs can have limited funding, and some offers may close once the available funds run out.
One last thing: don’t assume rebates can be combined. Some state, local, and utility incentives can be stacked, while others cannot. Check the rules for each program before counting on multiple incentives to reduce the cost of your tankless water heater.
How To Maximize Your 2026 Rebate
Look, I’ve been through the process myself, and I know tax rebates can feel like a maze. But trust me, with a little PLANNING, you can really make those credits work in your favor. If you’ve just installed a tankless water heater—or any other Energy Star–rated upgrade—here’s how to get the most out of those savings.
Start With A Home Energy Audit
Before you dive into upgrades, I always recommend getting a home energy audit. It’s like getting a full check-up for your house. You’ll find out exactly where you’re wasting energy and which improvements will save you the most money long-term.
Don’t Forget State And Local Rebates
While there are no more federal credits, your state and local utilities probably have their own rebate programs. These often change, so keep an eye on their websites. It might feel like extra work, but those reimbursements can really stack up and boost your savings.
Hire Qualified Professionals
I can’t stress this enough: get pros to install your tankless water geyser. Some water heater rebates require an approved or licensed contractor, so check the program rules before scheduling the installation. Plus, if the PAPERWORK or TAX FORMS start to feel overwhelming, bring in a tax professional who knows this stuff inside and out. It’s worth the peace of mind.
Conclusion
Look, upgrading to a tankless water heater isn’t just about getting rid of the storage tank. It can be a smart investment if the system is properly sized and installed for your home.
The incentive can make the upfront cost easier to swallow, but don’t let the promise of a rebate push you into buying the wrong unit. Check the available programs first, make sure the model qualifies, and understand what the utility or local program requires before you commit to the installation.
Keep your paperwork in order, pay attention to application deadlines, and check whether different incentives can actually be combined. The rules vary from one program to another, so what worked for someone in another state may not work for you.
At the end of the day, the best approach is pretty simple: find the rebate first, choose the right water heater, and make sure you meet the requirements. Do that, and you can lower the upfront cost while getting a tankless system that’s a good fit for your home.
Quick Recap
The federal 25C tax credit for qualifying tankless water heaters ended after December 31, 2025. For a tankless water heater installed in 2026, your best opportunities are state, local, and utility rebates. Eligibility varies by location, utility, equipment, and installation requirements.
Before buying a unit, check ENERGY STAR’s Rebate Finder and your local utility’s current program. Some 2026 programs are specifically available for ENERGY STAR-certified tankless gas water heaters, while others may have different equipment requirements.
If you qualify for a local rebate, keep your purchase receipt, model information, installation invoice, and any other documents required by the program. Also check whether pre-approval or an approved contractor is required before installation.
