Key Takeaways

  • The IRC 48 Investment Tax Credit offers tax benefits from 6% to 50% for property owners using renewable energy systems
  • Eligible properties include solar, geothermal, fuel cells, energy storage, and other renewable systems
  • Strategic implementation through new development or retrofitting boosts investment returns
  • Combining these credits with cost segregation studies multiplies tax advantages
  • Recent IRS regulations have clarified definitions for qualifying energy property

Understanding the IRC 48 Investment Tax Credit

The IRC 48 Investment Tax Credit (ITC) encourages the adoption of renewable energy in real estate. Unlike deductions that reduce taxable income, this credit directly cuts tax liability dollar-for-dollar based on qualifying renewable energy equipment costs.

Quantifying the Tax Credit

Currently, base credit rates start at 6% but can reach 30% when meeting prevailing wage and apprenticeship requirements. There is an additional domestic content 10% bonus for use of US materials such as steel, iron, or manufactured product. Another 10% bonus can be added for properties in an “Energy Community” for a total possible of 50%. 



  • Final Regulations Issued: The IRS and Treasury have released regulations clarifying energy property definitions and credit rules

Qualifying Property Types

The credit applies to virtually any real estate type with qualifying energy systems:

  • Commercial buildings
  • Multifamily housing
  • Industrial facilities
  • Office buildings
  • Retail properties
  • Hotels and hospitality

Energy Property Requirements

Eligible energy property now includes:

  • Solar energy equipment
  • Geothermal systems
  • Energy storage technologies
  • Waste energy recovery property
  • Combined heat and power systems
  • Qualified biogas property
  • Microgrid controllers


According to IRS regulations, energy storage technology co-located with qualified facilities can claim Section 48 credits.

Strategic Implementation in Real Estate

New Development and Retrofitting Projects

For new construction, renewable energy systems can be built in from the ground up, following a strategic timeline from design through installation and claiming the credit.


For existing properties, the credit applies to renovations adding qualifying energy systems. A thorough cost-benefit analysis should consider current energy costs, available space, structural considerations, and possible local incentives.

Advanced Tax Strategies

Combining with Cost Segregation Studies

Pairing IRC 48 credits with cost segregation studies creates powerful tax advantages:

  • Cost segregation speeds up depreciation deductions
  • The combined effect of credits and accelerated depreciation greatly improves project economics
  • Can cut payback periods by 50% or more compared to energy savings alone


For more on how cost segregation works with renewable energy investments, see our cost segregation guide.

Direct Payment and Credit Transfer Options

The Inflation Reduction Act allows:

  • Some taxpayers to claim cash payments instead of tax credits
  • Transfer of credits to unrelated taxpayers
  • As of March 2024, over 500 entities had registered for these options

Compliance and Risk Management

Maintaining Compliance

Both IRC 48 and new Section 48E credits have a five-year recapture period. Under 48E, credits can be recaptured if a facility exceeds greenhouse gas emissions of 10 grams CO2/kWh within five years after being placed in service.

Events triggering recapture include:

  • Selling energy property
  • Stopping qualified use
  • Changing use to non-qualifying purposes

Documentation Requirements

Thorough documentation is essential and includes:

  • Technical specs proving system eligibility
  • Cost segregation between eligible and ineligible expenses
  • Evidence of placed-in-service dates
  • Proof of system operation
  • Domestic content documentation for bonus credits

2025 Program Changes

The application period for the 2025 low-income communities bonus credit program opens January 16, 2025, and closes August 1, 2025. This gives an additional 10-20% credit for applicable energy facilities under 5 megawatts.


The IRS has redesigned Form 3468 to support provisions created by the Inflation Reduction Act, with separate forms needed for each facility or property.

Conclusion

While IRC 48 is moving to new frameworks, renewable energy tax credits remain powerful tools for real estate investors.

 

To maximize these benefits, investors should:

  • Plan early in development
  • Get specialized expertise
  • Consider entity structure carefully
  • Keep meticulous documentation
  • Integrate planning with other tax strategies like cost segregation

Cost Segregation Cost segregation has always been a powerful tax strategy for real estate investors, but the next three years are especially important.

Below is a detailed breakdown of how to unlock bonus depreciation in 2024, 2025, and 2026 with a structured cost segregation strategy.
