Window Rebates vs. Tax Credits: What Qualifies and What Doesn’t?

Understanding incentives for energy-efficient window replacement 

Homeowners often hear about window rebates and tax credits, but the rules for each can be confusing. Understanding the difference can help you plan your project and avoid missed savings. 

What is a window rebate? 

A rebate is typically offered by a local utility and paid directly to the homeowner after installation. 

In Chelan County, Chelan PUD offers rebates for qualifying window and patio door replacements in existing homes. 

Rebates usually require: 

• Primary electric heat 

• Specific U-factor ratings 

• Documentation and photos 

• Submission within a defined timeframe

What is a federal tax credit? 

A tax credit reduces the amount of federal income tax you owe. For windows: 

• Homeowners may qualify for 30% of the project cost up to $600 

• Products must meet ENERGY STAR Most Efficient criteria 

Tax credits are claimed when filing taxes, not paid out immediately. 

Can you use both? 

In many cases, yes. Rebates and tax credits often stack—as long as the windows meet each program’s requirements. 

However: 

• Not all products qualify 

• New construction is usually excluded 

• Documentation is critical 

How to avoid disqualification 

Common mistakes include: 

• Choosing windows that miss U-factor requirements 

• Missing application deadlines 

• Incomplete documentation 

• Assuming all ENERGY STAR windows qualify 

Working with an experienced installer helps avoid these issues.
