Offset the costs of building
energy-efficient properties with 45L tax credits.

45L Tax Credit

The Section 45L tax credit offers a compelling financial advantage for those who invest in energy-efficient construction and renovation. Claiming this credit can result in significant savings on your tax bill.

The credit amount is up to $5,000 per eligible dwelling unit for new energy-efficient homes. The credit is available to the property owner or developer who constructed or renovated the property, not to the eventual homebuyer.

Qualifying for 45L Tax Credits

Eligible properties can be single-family homes, townhouses, condominiums, or apartment buildings. To qualify for the credit, the dwelling units must meet certain energy efficiency standards, which are usually determined by comparing the energy consumption of the property to that of a reference property built according to the standards set by the International Energy Conservation Code (IECC).

The following energy-efficient buildings leased or sold through qualify for the Section 45L tax credit:

  • Residential Condominiums

45L Tax Credits and ENERGY STAR

ENERGY STAR, a program by the US Environmental Protection Agency (EPA), acts as a benchmark for energy-efficient products and homes. It is a trusted mark of quality, signifying that a home meets specific energy performance standards established by the EPA.

The 45L tax credit and ENERGY STAR work hand-in-hand. By building homes that meet ENERGY STAR standards, builders can become eligible for the tax credit.

What Qualifies As An ENERGY STAR Certified Home?

  • High-Quality Insulation
  • High-Performance Windows
  • High-Efficiency Heating & Cooling System For Improved Comfort
  • Comprehensive Water Management Techniques That Protect Against Moisture Damage
  • Advanced Air Sealing

ENERGY STAR certified new homes are energy efficient by design, with savings that start now and continue into the future. Better systems and construction features make all the difference throughout your home. ENERGY STAR certified homes are at least 10 percent more energy efficient than standard new homes built to code—and even more efficient when compared to existing homes.
