Quick answer

When a rental property is sold, gain is generally calculated using adjusted basis, which reflects depreciation allowed or allowable. The depreciation-related portion of gain can receive different federal tax treatment from other long-term gain. The actual calculation depends on allocation, improvements, selling costs, prior use and entity structure.

Start with original basis

Basis commonly begins with the purchase allocation to building and land, then includes qualifying acquisition costs. Land is not depreciated. Settlement statements, appraisals and allocation workpapers establish the starting point.

An unsupported allocation can affect years of depreciation and the eventual sale calculation. Preserve the method used and any professional advice.

Track basis adjustments during ownership

Capital improvements and certain acquisition costs can increase basis. Depreciation deductions, casualty adjustments and other items can reduce it. Repairs usually affect current expenses rather than basis.

Maintain a fixed-asset schedule showing each component, placed-in-service date, cost, recovery method, depreciation claimed and disposition.

Allowed or allowable depreciation matters

Federal tax rules can require basis reduction for depreciation that was allowed or could have been allowed. Failing to claim a deduction does not necessarily preserve basis for the sale.

If prior depreciation was missed or incorrect, discuss correction methods with a qualified tax professional before filing the sale-year return.

Separate building, land and other assets

A sale can involve land, building, appliances, furniture and improvements with different tax characteristics. The contract price and selling costs may need reasonable allocation among assets.

Prior personal use, a home-office or conversion from a residence to rental use can add basis and exclusion complications.

Prepare before accepting an offer

Estimate adjusted basis, selling costs, outstanding passive-loss carryovers and tax exposure before deciding how much net cash the sale may produce. Mortgage payoff is a cash calculation and does not determine taxable gain.

Gather depreciation schedules, returns, invoices, settlement documents and improvement records early. Sale structure, installment terms and exchanges have separate requirements and deadlines.

Frequently asked questions

Is depreciation recapture based on the mortgage balance?

No. Tax gain is based on amount realized and adjusted basis; the mortgage payoff affects cash proceeds.

What if I never claimed depreciation?

Basis may still be reduced by depreciation allowable. A tax professional can review correction options.

Does converting a former home to a rental change the calculation?

Yes. Conversion basis, personal-use periods and possible home-sale exclusion rules can affect the result.
