§04Proactive strategy

Find the studies hiding in your book.

Drop in a client’s fixed-asset or depreciation schedule. Our analyzer scans every property for cost seg eligibility, flags Form 3115 lookback candidates, and models the year-one benefit at the client’s bracket. You walk into the next meeting with a one-page partner-led brief. You bring the strategy. We do the math.

After working with another provider previously, the Segtax difference in quality and partnership was clear.

Not only is the platform strong, but the team behind it operates more like a true partner than a typical software provider. Their pace of development and willingness to collaborate is something I haven’t seen from many companies.

§09FAQ

Questions partners ask first.

At the simplest, you email us a property address and we take it from there. Firms that want more structure get a partner portal where you can add properties, track every client engagement, and see exactly where each study is in the process — no need to chase us for updates. Either way, your team won't need training to get started.
