Wood and pellet stove incentives in Washington (2026)
The federal 25C tax credit for biomass stoves ended for appliances placed in service after December 31, 2025 (One Big Beautiful Bill Act, Pub. L. 119-21 §70505, amending IRC §25C). No federal credit applies to a 2026 installation. The table below covers Washington state, utility, and local programs only.

What we could not check in Washington
Some Washington sources could not be reached during our review. We list what we tried and what happened, so you can judge the gap yourself rather than read an empty table as an answer.

Regional clean air agency wood stove programs —
Spokane Regional Clean Air Agency's changeout page was read 2026-10-21 (wood to pellet $1,400, wood to wood $1,000, wood to gas $1,800; Fall 2025 to Spring 2027), and Puget Sound Clean Air Agency's page offers $500 to recycle an eligible wood stove. Neither is listed here yet, pending editorial review. The other regional clean air agencies could not be confirmed, so this is a partial gap, not a finding that no other programs exist.

Figures we withheld
We found these referenced somewhere, but could not confirm them at the administering agency's own current page. We would rather show you nothing than a number that may have expired.
- Wood Smoke Reduction Grants (biennial) — Application period stated as July 1 – August 5, 2025 (closed); reopens mid-summer each biennium if funded. No consumer dollar figure stated.
