Free Estimate

For property owners

Your building is already paying you back. Faster than your CPA is depreciating it.

A cost segregation study reclassifies part of your purchase price into 5-, 7-, and 15-year assets — pulling deductions forward into the years you actually need them. Engineering-based, IRS-aligned, and estimated free before you commit.

What it looks like

The same property, classified correctly

Nothing here changes what you own or what you paid. It changes which depreciation schedule each component legally belongs on — and that pulls real money into year one.

How it works

Three steps, and your CPA stays in control

  1. Free benefit estimate

    Send the property address, purchase price, and placed-in-service date. You get a no-cost projection of the deduction and fee — before anything is signed.

  2. Engineering study

    CSSI engineers analyze the property and its cost detail, then classify components into 5-, 7-, 15-, and long-life categories with documentation for each.

  3. Report to your CPA

    You and your CPA receive the full study, the depreciation schedules, and the §481(a) detail when a look-back applies. Your CPA files it.

The questions owners actually ask

Straight answers, including the parts that don't flatter the pitch.

Isn’t this just deferring tax I’ll pay later anyway?

Largely yes — and that’s the point. A dollar deducted today is worth more than a dollar deducted in year 27, because you redeploy it now. Many owners also offset the eventual recapture by exchanging, refinancing, or holding through a step-up. Your CPA models the exit; we supply the engineering.

My CPA already depreciates the property. What changes?

Standard practice puts the whole building on a 27.5- or 39-year line. A cost segregation study breaks out the components that legally belong on 5-, 7-, and 15-year lives — flooring, fixtures, dedicated wiring, site work — with an engineering basis behind each one. Same property, correctly classified.

Will this raise my audit risk?

An engineering-based study performed to IRS Audit Technique Guide standards is the documented method. The risk sits with unsupported rule-of-thumb allocations, not with a study that shows its work. Every study comes with the documentation your CPA would need.

What does it cost, and when does it pay for itself?

Fees are quoted per property based on type, size, and basis — no percentage of savings. We only recommend a study when the projected benefit clears the fee by a wide margin, and you see that math in the free estimate before you commit.

How long does the study take?

Typically three to six weeks from engagement to delivered report, depending on property type and document availability. Look-back studies on prior-year acquisitions follow the same timeline.
