Federal Tax Credits for Energy-Efficient Windows: What Florida Homeowners Qualify For

The Inflation Reduction Act expanded the Energy Efficient Home Improvement Credit, and many Florida homeowners who installed qualifying windows and doors can claim a meaningful tax credit. Here's what you need to know — with the important caveat that tax situations vary, and you should confirm specifics with a qualified tax professional.

The Energy Efficient Home Improvement Credit (Section 25C)

The current program allows homeowners to claim a credit of 30% of the cost of qualifying energy-efficient home improvements, with a maximum of $600 for exterior windows and skylights per year. This is a tax credit (not a deduction) — it reduces your tax bill dollar-for-dollar. For a qualifying window purchase of $2,000 in products, that's a $600 credit directly off what you owe.

What Qualifies

To qualify, windows must meet Energy Star "Most Efficient" criteria, which for Florida's climate zone (Zone 2, hot-humid) means a U-Factor of 0.25 or lower and a Solar Heat Gain Coefficient (SHGC) of 0.22 or lower. Many quality impact windows meet these specifications — but not all do. When we quote your project, we can confirm whether the products we're proposing meet current Energy Star criteria for the credit.

Documentation Required

To claim the credit, you'll need:

• Manufacturer's certification statement (we provide this with every qualifying installation)
• Purchase receipts (labor costs are not eligible, only product costs)
• IRS Form 5695 filed with your return

The $600 Cap and Project Timing

The $600 annual cap is per-year, and the credit renews annually. A homeowner replacing all windows in a single year is limited to $600 regardless of total product cost. However, splitting a large project across two tax years (some windows in December, the rest in January) would allow $600 each year — worth discussing with your accountant.

Florida-Specific Incentives

Some Florida utilities (Duke Energy Florida, Tampa Electric) offer rebates for energy-efficient home improvements including qualifying windows. Check your utility's rebate program before installation — these can stack with the federal credit.
