What is the 25C Tax Credit?

The 25C Tax Credit, also known as the Energy Efficient Home Improvement Credit, is a federal tax credit provided to homeowners who make eligible energy-efficient improvements to their homes.

Purpose and Benefits of the 25C Tax Credit

The primary purpose of the 25C Tax Credit is to incentivize homeowners to make energy-efficient upgrades to their properties.

By offering a tax credit, the government aims to encourage the adoption of energy-saving technologies and practices, which contribute to a more sustainable and environmentally friendly future.

This is on a dollar-by-dollar basis.

The benefits of the 25C Tax Credit are twofold. Firstly, homeowners can enjoy reduced energy costs by implementing energy-efficient improvements. These improvements can lead to lower utility bills, providing long-term savings and increased financial stability.

Secondly, the tax credit itself offers a direct financial benefit. By claiming the credit on your tax return, you can potentially reduce your tax liability. This can help offset some of the expenses incurred in making the energy-efficient upgrades to your home. In some cases, you can get paid to sell your tax credit for cash today, rather than wait till filing your taxes.

Eligibility Criteria and Amounts for 25C Tax Credit

To be eligible for the 25C Tax Credit, homeowners must make certain energy-efficient improvements to their homes. These improvements fall into specific categories and must meet certain standards set by the Internal Revenue Service (IRS). Common eligible improvements include:

Insulation (Weatherization)

Adding insulation to the home's walls, attic, or floors. The insulation must meet the criteria set by the 2015 International Energy Conservation Code (IECC).

Weatherization upgrades keep your house from exchanging too much air with the outside. You may be able to claim your 25C credit for materials like:

  • Insulation batts and rolls
  • Blown insulation fibers
  • Rigid insulation boards
  • Expanding spray foam insulation
  • Weatherization supplies such as specialized caulk, tape, spray foam, and sealants


Windows and Doors

Installing energy-efficient windows and doors. Windows and doors must have a U-factor and Solar Heat Gain Coefficient (SHGC) that meet the ENERGY STAR® requirements.


HVAC Systems

Upgrading heating, ventilation, and air conditioning systems to more energy-efficient models. HVAC systems must meet certain energy efficiency ratings, such as SEER (Seasonal Energy Efficiency Ratio) for air conditioners or AFUE (Annual Fuel Utilization Efficiency) for furnaces.


Water Heaters

Replacing old and inefficient water heaters with energy-efficient alternatives. Water heaters must have an energy factor (EF) equal to or exceeding the requirements specified by the IRS.


Renewable Energy Systems

Installing solar panels, wind turbines, or geothermal heat pump systems. Renewable energy systems must meet specific performance and certification standards, such as being certified by the Solar Rating and Certification Corporation (SRCC) for solar panels.


Residential Property Eligibility

In addition to meeting the requirements for eligible improvements, the property itself must also meet certain criteria to qualify for the 25C Tax Credit.

Generally, the credit is available for improvements made to a taxpayer's primary residence, but there are some exceptions for certain types of residential properties.

It's important to note that rental properties, second homes, and new construction properties are typically not eligible for the 25C Tax Credit. However, there are separate tax incentives available for these types of properties, such as the 45L Tax Credit for energy-efficient new construction.

How Much Will I Get From the Credit?

Beginning Jan. 1, 2023, the credit equals 30% of certain qualified expenses, including:

  • Qualified energy efficiency improvements installed during the year (as mentioned above)
  • Residential energy property expenses (as mentioned above)
  • Home energy audits

There are limits on the allowable annual credit and on the amount of credit for certain types of qualified expenses.

The credit is allowed for qualifying property placed in service on or after Jan. 1, 2023, and before Jan. 1, 2033. You've got lots of time!

The maximum credit you can claim each year is:

  • $1,200 for energy property costs and certain energy efficient home improvements, with limits on doors ($250 per door and $500 total), windows ($600) and home energy audits ($150)
  • $2,000 per year for qualified heat pumps, biomass stoves or biomass boilers

The credit has no lifetime dollar limit. You can claim the maximum annual credit every year that you make eligible improvements until 2033.

The credit is nonrefundable, so you can't get back more on the credit than you owe in taxes. You can't apply any excess credit to future tax years.

Remember, you can continue to claim the tax credit every year that you spend on a qualifying upgrade. If you get a heat pump next year, you can claim the credit. The year after, you can install improved insulation and windows. You'll get the credit again.

This recurring credit is going to make it great for homeowners who don't qualify for the Federal Rebate Programs - HEEHR and HOMES.

Building Envelope Components

These components must have an expected lifespan of at least 5 years and include:

  • Exterior doors that meet applicable Energy Star requirements. Credit is limited to $250 per door and $500 total.

  • Exterior windows and skylights that meet Energy Star Most Efficient certification requirements. Credit is limited to $600 total.

  • Insulation and air sealing materials or systems that meet International Energy Conservation Code (IECC) standards in effect at the start of the year 2 years before installation. These items don't have a specific credit limit, other than the maximum credit limit of $1,200.

Labor costs for installing building envelope components don't qualify for the credit.

Home Energy Audits

A home energy audit for your main home may qualify for a tax credit of up to $150.

In order to qualify, the home energy audit must:

  • Include a written report and inspection that identifies the most significant and cost-effective energy efficiency improvements with respect to the home, including an estimate of the energy and cost savings with respect to such improvement, and
  • Be conducted and prepared by a home energy auditor

Starting in 2024, the following additional requirements must be met:

  • The inspection must be conducted by a qualified home energy auditor, defined as an individual who is certified by one of the qualified certification Programs listed on the Department of Energy certification programs for the Energy Efficient Home Improvement Credit (Section 25C) at the time of the audit, or under the supervision of a qualified home energy auditor;
  • The written report must be prepared and signed by a qualified home energy auditor, be consistent with industry best practices, and include:
  • The qualified home energy auditor's name and relevant employer identification number (EIN) or other type of appropriate taxpayer identifying number, if the auditor does not have an EIN;
  • An attestation that the qualified home energy auditor is certified by a qualified certification program; and
  • The name of such qualified certification program
