Wood Stove Tax Credit in 2026: What Ended and What to Check Instead

Many pages online still promise a 30% federal credit on a new wood stove. For a stove installed in 2026, that is out of date.

What the federal credit was

ENERGY STAR’s page for the biomass stove credit says it was “effective for products purchased and installed between January 1, 2023, and December 31, 2025.” It was worth 30% of project cost up to $2,000, and the stove needed a thermal efficiency of at least 75% (HHV). It was claimed on IRS Form 5695 (ENERGY STAR).

What that means now

• Installed in 2026: the federal biomass stove credit does not apply.
• Installed in 2025: if the stove met the requirements, the credit may apply on your 2025 return. Check the Form 5695 instructions or a tax professional.
• Bought in 2025 but installed in 2026: the ENERGY STAR wording covers products “purchased and installed” within the window, so ask a tax professional before assuming anything.

Where to look instead

• Your state energy office and the DSIRE database of state incentives.
• Local air-quality districts, which sometimes fund change-outs of old uncertified stoves.
• Your electric or gas utility.

Programs open and close often. Check the program’s own page for current terms before you buy, and keep receipts and the stove’s efficiency documentation.

Why so many pages still mention the credit

The biomass stove credit ran for three tax years, and a lot of retailer and manufacturer pages were written while it applied. Some still show “30% back” banners, and some list stoves as “tax-credit eligible” based on the 75% (HHV) efficiency requirement. That eligibility language described the 2023-2025 window. It does not create a credit for a stove installed in 2026.

How the credit worked, for 2025 installations

If you installed a qualifying stove in 2025, these are the points to check against the IRS instructions with your tax preparer:

Source: ENERGY STAR. Keep the manufacturer’s certification statement showing the HHV efficiency, and your itemized receipt.

HHV vs LHV: the number that decided eligibility

Stove makers often publish two efficiency figures. The higher heating value (HHV) figure counts the energy used to evaporate water in the wood and is always the lower of the two numbers; the lower heating value (LHV) figure leaves it out and looks better. The Drolet Escape 1800, for example, is listed at 72% HHV and 77% LHV (Drolet). A stove listed at “77% efficient” could still have been under the 75% HHV line. When you compare stoves today, compare HHV to HHV, the basis the credit used.

Other ways to lower the cost in 2026

• Change-out programs. Some air districts and states pay part of the cost of replacing an old, uncertified stove with a cleaner model, often with income limits and a requirement to destroy the old stove. Search your state environmental agency and DSIRE.
• Utility programs. Fewer utilities fund wood heat than heat pumps, but some rural co-ops run programs. Ask.
• Install costs. The stove is often not the biggest line item. Chimney, connector, hearth pad and permit can add a large share; see the buyer’s guide for what to budget for.
• Right-sizing. A stove matched to your heat need burns cleaner and uses less wood. Try the stove sizing calculator.

Checklist before you rely on any incentive

1. Read the program’s own page, not a retailer’s summary.
2. Check whether the stove must be on the EPA certified list, and at what efficiency basis.
3. Check whether professional installation, a permit or an inspection is required.
4. Check whether you must apply before you buy.
5. Keep receipts, the certification label photo and the manual.

If you’re replacing an old stove

Pre-1988 stoves were sold before EPA emission limits applied. Current EPA-certified stoves have to meet the 2020 limits of the New Source Performance Standards (EPA), so a change-out can cut smoke substantially even without a tax credit. If a local program pays for it, it will usually require the old stove to be removed and scrapped and the new one to be on the EPA certified list.

FAQ

Does a 2026 stove purchase qualify for any federal credit?

Not under the biomass stove credit, which covered products purchased and installed through December 31, 2025. We have not found a replacement federal credit for wood stoves as of October 12, 2026. Check current IRS guidance or ask a tax professional.

Is a pellet stove treated differently?

The 2023-2025 biomass credit covered both wood and pellet stoves that met the efficiency requirement, and it ended on the same date for both.
