Are New Windows Tax Deductible?

March 30, 2022

It’s that time of year again. It’s a time that we can’t avoid, although we wish we could. Benjamin Franklin once said, “Our new Constitution is now established and has an appearance that promises permanency; but in this world, nothing can be said to be certain, except death and taxes.”

As tax season approaches, you might be wondering how you can reduce the financial impact. If you’ve recently invested in home improvements, like installing new windows, you might also be curious if these upgrades are eligible for a tax credit for energy efficient windows.

The short answer is – it depends. The rules surrounding tax credits for new windows can be complex, but we’re here to help shed some light on the subject. However, let’s start with an important disclaimer.

Disclaimer: Always Consult a Tax Professional

Before diving into the details, it’s essential to note that you should consult with a tax professional to determine whether your new windows are eligible for an energy tax credit for new windows. We provide general information, but a qualified professional can give you advice tailored to your specific situation.

While we’ve gathered insights from our 20 years of installing windows in San Antonio and Corpus Christi, tax laws change frequently, and there are various requirements at federal, state, and local levels. To maximize your savings, seek guidance from a tax expert before making any purchase decisions.

How Energy-Star Ratings Impact Tax Credits for New Windows

One of the key factors in determining if your new windows are eligible for a tax credit is whether they are Energy-Star rated. This certification indicates that the windows meet energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).

Your windows can be of any style—casement, bay, single-hung, double-hung, etc.—but they must have the Energy-Star rating to qualify for a deduction. Additionally, these windows must be installed in your primary residence. Upgrading windows on a vacation home, unfortunately, won’t qualify for tax deductions, although it may offer other benefits.

It’s also important to remember that Energy-Star rated windows offer ongoing financial benefits beyond tax season. They help maintain a consistent indoor temperature, reducing the workload on your HVAC system and lowering your energy bills throughout the year.

Do I Need to Replace All Windows to Qualify for a Tax Deduction?

No, you don’t need to replace all your windows at once to qualify for a tax deduction. Whether you replace one window or several, you can still qualify, although there is a cap on how much you can claim. More on that below.

For instance, if a baseball breaks one of your windows and you decide to replace it with an Energy-Star rated window, you can claim a deduction for that single window. As you continue upgrading the windows in your home, you can claim deductions for each replacement, up to a certain limit.

How Much Can I Claim?

As of the 2021 tax year, you can claim up to 10% of the cost of eligible home upgrades, with a cap of $500. For example, if you spend $1,000 on Energy-Star rated windows, you can receive a $100 tax credit. However, if your total upgrade costs $20,000, you’re still capped at $500.

These limits apply annually. So, if you max out your credit with window replacements in one year, and then purchase a qualifying HVAC unit the next year, you can claim the credit again for the new year.

Claiming Other Energy-Efficient Home Improvement Deductions

There are other energy-efficient home improvements that you may be able to deduct or receive a credit for. These include:

  • Energy-efficient doors, windows, and skylights
  • Energy-efficient roofing materials
  • High-efficiency HVAC systems
  • Energy-efficient water heaters
  • Home insulation improvements

Remember, these items must meet specific requirements to qualify for tax deductions or credits, so it’s essential to verify eligibility with a tax professional.


While new windows can be a significant investment, they’re a worthwhile one for your home’s comfort and energy efficiency. By planning your upgrades strategically and consulting with a CPA, you can make the most of available tax incentives and save money in the long run.

If you’re considering upgrading your windows, don’t wait too long. Tax incentives often decrease over time, so act now to maximize your savings.
