For CPAs & tax professionals

Engineering-based cost segregation, built for CPAs.

Cost segregation referrals, white-label deliverables, free training, and a priority-service partner program for CPAs. TDA handles the engineering so you can deliver accelerated depreciation savings to your clients.

Built for the engagements you already manage

Your client comes to you for tax strategy. We’re the engineering arm.

Most CPAs don’t want to spend a weekend tearing apart a depreciation schedule to identify 5-year personal property. We do that — on the same week you flag the property — and hand you a deliverable your client can file with confidence.

Your firm controls the client relationship; we handle the engineering.

What you’re facing

Sound familiar?

The expertise gap

You know cost seg helps your clients — but you don’t have the engineering team in-house.

The trust gap

When you do refer studies, you don’t always know whether the report will hold up under audit.

The economics gap

You want a referral relationship that’s clean, recurring, and compensates you for the work.
