Energy Tax Credits for Window Replacement in Virginia 2026

What The Window Tax Credit Actually Covers

In most cases, the main tax benefit for replacement windows in Virginia comes from the federal Energy Efficient Home Improvement Credit rather than a state-specific window program.

This is a tax credit, not an instant rebate. You cover the project cost up front, then claim the credit on your return if the product and installation qualify.

Under the current federal structure, qualifying windows generally can earn a credit equal to 30% of the cost, up to a $600 limit for windows each year, subject to the overall annual cap for home energy improvements.

Because the credit has an annual limit, it is worth looking at the whole project plan before you sign a contract.

A tax professional can tell you how the credit applies to your return, but the product itself still has to qualify.

What To Look For Before You Buy
