Attic Insulation Tax Credits To Know in 2026

Owning a home or property is a very rewarding experience, but it can be expensive at times. It takes a lot of hard work, and frankly, money, to keep a home in good shape. Recurring costs like maintenance needs and bills are usually expected, but unexpected projects or setbacks can be impactful for your wallet if you aren’t ready for them.

For example, if you have noticed that your home is getting too hot in the summer for no apparent reason, you might wonder if an attic insulation upgrade is in your future. While that fact may seem daunting, did you know that there are various tax credits you can use to your advantage to help you save money on this project?

Let’s explore the attic insulation tax credits to know in 2026 so you can save money and stay cozy.

What Are Energy Efficiency Tax Credits?

When it comes to home improvements, tax credits can make a big difference in what you end up paying for out of pocket. But do you know what a tax credit is and how they can help?

A tax credit is a dollar-for-dollar reduction of the income tax you owe to the IRS. Unlike a deduction, which reduces your taxable income, a credit directly lowers your tax bill. For example, if you owe $2,000 in taxes but qualify for a $1,200 tax credit for a home improvement project, your final bill you have to pay is only $800.

The federal government has offered tax incentives for energy-efficient home upgrades for the last few years under the Energy Efficient Home Improvement credit. These incentives were expanded as part of the Inflation Reduction Act of 2022. This act allows homeowners to claim tax credits through 2032 on eligible improvements.

One of these eligible improvements is attic insulation! As long as the insulation material you choose meets the IRS and Energy Star efficiency requirements, your project will qualify for a lucrative tax credit.

Tax Credit Details for Attic Insulation

If you are upgrading your attic insulation before the year ends in 2025 or in 2026 and beyond, make sure you know all about the federal tax credit for insulation projects! Right now, homeowners can receive a tax credit worth 30% of their insulation project, up to $1,200 per year. It’s important to note that this limit is an annual cap, so you can make multiple qualifying improvements to your home over the next few years at a significantly reduced cost.

For example, if you purchase $1,000 worth of qualifying attic insulation, you will receive a tax credit of $300. Remember, when you purchase your insulation matters. If you purchase it in 2025, you will receive that tax credit on your 2025 taxes. If you purchase it in 2026, you will have to wait until spring of 2027 to file for the credit during that year’s tax season.

So, what types of insulation qualify? To qualify, the product must meet the criteria established by the Department of Energy (DOE) and/or ENERGY STAR®, and it must be designed to reduce heat loss or gain in your home. If you are working with an insulation installation professional, they will be able to tell you exactly what types of insulation qualify.

Another thing to note about this tax credit is that it requires the insulation to be installed in your primary residence, not a vacation home or rental property.

How To Qualify for an Attic Insulation Tax Credit

Claiming this attic insulation tax credit in 2026 and beyond is a straightforward process as long as your insulation meets the requirements and you obtain the correct documentation. Here’s what you need to know to qualify:

🏠 Your Home Must Be Eligible

To claim this federal energy efficiency tax credit, the improvement must be made to your primary residence. This means:

• You own and live in your home full-time.
• The home is located in the United States.
• It is an existing home (new constructions are not eligible).

Single-family homes, townhouses, mobile homes, and condos all qualify as long as your property meets all of the above requirements.

🛠️ Insulation Must Be Qualified and Installed in the Correct Year

If you are hoping to claim this credit during this upcoming tax season, the insulation materials must be purchased and installed before December 31st of this year. If you are planning to tackle this project in 2026, be sure the materials are purchased and installed from January 1st-December 31st of 2026.

Only material costs are eligible for the credit. Labor and installation fees are not covered. However, hiring an attic insulation installation team is ALWAYS RECOMMENDED.

🧾 Keep Receipts and Documentation

So far, this process is smooth and simple to follow! However, don’t forget to keep your receipts and document the process; otherwise, you might not qualify for the credit. Save all receipts and invoices related to the insulation and installation.

Document the installation date, location, and product type for your own personal records. Keep all of these forms and receipts in a safe location until tax time comes around in the spring.

🧮 File the Right IRS Form

When tax season arrives, you will need to fill out IRS Form 5695 (the Residential Energy Credit) with your federal tax return. Once you fill out the form, you will have to transfer the final amount to Schedule 3 of your Form 1040.

If you are doing your own taxes, make sure you fill out these forms accurately! If you hire a licensed tax professional, make sure they have all the documentation needed to fill them out on your behalf.
