Why CTI for 179D
Carrier Hourly Analysis Program
The Department of Energy provides numerous programs for computing the 179D deduction. Carrier Hourly Analysis Program is one of the first approved programs and to this day is regularly used in the design field. Because of its widespread use, we are confident we are getting the most accurate results.
Onsite Surveys
Gathering clear and concise data is important when surveying buildings. Surveys are completed so that there is no question that the energy-efficient measures designed have been installed. Our detailed surveys have found that they are supportive of an IRS Audit.
Certifying Professional Engineers
It is important to have input from professional engineers who are active in the field. Their support ensures our modeling is continuously evolving with the current market.
Optimize Tax Savings
Your goal is to maximize your depreciation potential and cash flow. You never know what opportunities you may miss or what mistakes might cost you if left to your own devices.
