Why cost segregation
Turn depreciation into cash flow
Accelerate deductions
Move eligible building components from a 27.5-year life into 5- and 15-year buckets — pulling deductions forward into your early ownership years.
Improve cash flow
Larger up-front deductions can reduce current-year taxable income, keeping more capital working in your portfolio instead of going to taxes.
Know before you commit
A free preliminary estimate shows the potential upside up front, so you can decide whether a full engineering-based study makes sense for your property.

This is a preliminary estimate
SegDIRECT provides an educational, preliminary projection based on the information you enter. It is not a formal cost segregation study, an appraisal, or tax advice, and it does not guarantee any specific tax outcome. A qualified professional should review your specific situation before you rely on any figures. Final results require a complete engineering-based study.
Questions
Frequently asked
What is cost segregation?
Cost segregation is a tax planning method that identifies parts of a building — like certain fixtures, finishes, and land improvements — that can be depreciated over 5 or 15 years instead of the standard 27.5 years. Accelerating that depreciation can increase your deductions in the early years of ownership.
Is the SegDIRECT estimate the same as a full study?
No. SegDIRECT gives you a free, preliminary projection to help you decide whether a full study is worthwhile. A formal cost segregation study is a detailed, engineering-based analysis prepared and documented by professionals — that’s the work that supports the numbers you actually file.
How much does the estimate cost?
The preliminary estimate is completely free, with no login and no obligation. You only pay if you choose to move forward with a full cost segregation study.
What information do I need to get started?
Just a few basics about your property: type, purchase price, the date it was placed in service, and roughly how the cost breaks down between land and building. You can get an estimate in about two minutes.
Who is behind SegDIRECT?
SegDIRECT is a technology product of Wm. Neil Langlois CPA, LLC — a licensed CPA firm. That means the methodology and any full study are backed by a real, licensed professional, not an anonymous calculator.
