The sale price minus the original purchase price is not a complete taxable gain calculation. Depreciation, capital improvements, selling costs and other basis adjustments matter. A cost segregation strategy can make the asset history more detailed because separate components may have different tax character. Keep the original study and depreciation schedules instead of relying on the current balance sheet.
Separate gain calculation from gain character
Begin with amount realized and adjusted basis, then analyze character and applicable depreciation-related rules. Debt payoff affects cash received but does not operate as a general deduction from taxable gain. Suspended passive losses require their own disposition review, including whether the transaction meets the applicable full-disposition requirements. A gain model should also include state treatment and estimated payments rather than only an assumed federal capital gain rate.
Worked planning example
A property has $900,000 of starting tax basis, $80,000 of capital additions and $260,000 of depreciation. Simplified adjusted basis is $720,000. A $1,100,000 sale with $60,000 of selling costs yields $1,040,000 before other adjustments, producing $320,000 of preliminary gain. The outstanding loan changes closing cash but not this simplified gain computation. Next classify the gain and test any suspended losses. The illustration does not establish a tax rate or final liability.
Records to bring to the review
- Reconcile original basis and capital improvements.
- Retain accumulated depreciation by asset.
- Separate debt payoff from gain computation.
- Model gain character, suspended losses and state tax.
Will all sale gain use one capital gain rate?
Not necessarily. Depreciation-related rules and asset character can create different treatment. Review the components rather than applying one rate to the full gain.
