How the math works

Gain = book − basis. Split 60/40 depreciation/appreciation (rough rule). DTL = depreciation × 25% + appreciation × effective.

$15M − $6.5M = $8.5M gain. 60% depr × 25% + 40% apprec × 28% = $2.23M DTL. Net $12.77M economic value.

Frequently Asked Questions

What's DTL?

Deferred Tax Liability: tax owed if asset were sold at current book value. Appears on balance sheet for C-corps, real estate partnerships rarely disclose. Important for estimating post-tax asset value vs pre-tax. DTL = (book − tax basis) × effective rate.

Why it matters?

Asset with $10M book, $5M tax basis, 28% combined rate: DTL = $1.4M. True economic value to seller = $10M − $1.4M = $8.6M. Buyers of partnership interests at book value effectively inherit the DTL. Widely ignored in casual pricing.

Managing DTL?

1031 exchange: rolls DTL forward (not eliminated). Installment sale: spreads DTL over payments. QOZ: defers then eliminates. Step-up at death: eliminates DTL. Estate planning: keep high-DTL assets until death for step-up elimination.
