What window rebates pay in Tacoma
We read Tacoma Power's window page on October 6, 2026. A Tacoma Power Participating Contractor must install the windows. The page we read does not state a cap on the number of windows.
Single-pane windows
Replacing existing single-pane windows in a home that heats mainly with electricity.
Single-pane glass sliding doors
Replacing a single-pane glass slider.
Double-pane metal-framed windows
Only if the old frames are metal.
Double-pane metal-framed sliding doors
Same rule for the frame.
Federal tax credit
The IRS says the energy efficient home improvement credit covers improvements made through December 31, 2025.
Working it out
A Tacoma home with ten single-pane windows and one single-pane slider could earn 10 times $100 plus $400, which is $1,400. The same home with double-pane metal-framed windows would earn 10 times $50 plus $200, or $700. Replacing double-pane windows that have vinyl or wood frames earns nothing, so check the frame before you plan.
Which windows count
Tacoma Power only pays when the existing windows and doors are single-pane or double-pane with metal frames. That is a narrow rule. Double-pane windows with vinyl or wood frames do not qualify. The US Census Bureau's American Community Survey (2020 to 2024) says about 64 percent of Tacoma homes were built before 1980 and 27 percent before 1940, so many older homes have single-pane glass still in place. About 63 percent of Tacoma homes heat with electricity, which also matches the program rule.
What does not qualify
Manufactured homes, new construction, do-it-yourself installs and buildings with five or more units are not eligible. Ask your contractor in writing what type of window you are replacing, because a mistake on that line can cancel the rebate. Take photos of the old windows before they are removed, showing the frames and glass. Keep the shipping slip for the new windows, which Tacoma Power requires.
Papers you need
Send the application for your project, a contractor bid (or the contractor's form), an invoice that meets Tacoma Power's rules and the window shipping slip. Tacoma Power can also point you to a list of required documents on its page. The rebate covers part of your costs.
Ask the contractor to measure and list every window and slider by room, with its glass type and frame type, before the bid is signed. That list becomes your proof of what was replaced. Also ask what the bid says about trim, disposal of the old windows and the warranty, since those costs are not part of the rebate. A written, itemized bid protects you if the number of qualifying windows changes during the job.
Windows are costly and the rebate is small, so think of it as a bonus on a project you wanted to do for comfort or repairs. If energy savings are your main goal, insulation usually pays more per dollar in the Tacoma Power program: $750 for each area, compared with $100 for each window.
If you rent or cannot qualify
With about 44 percent of Tacoma households renting, many readers cannot choose their windows. Ask your landlord whether they plan to apply, and point them to Tacoma Power's page. If your household income is at or below 150 percent of area median income, the City of Tacoma is a state partner for home electrification rebates, though that program lists heat pumps, water heaters, induction cooking, dryers and wiring, not windows. For help with drafty windows on a low income, ask your community action agency about the state weatherization program.
