Rental Property Sale Taxes: Basis, Depreciation, and 1031 Basics

Keep four numbers separate

The contract price is what the buyer agrees to pay. Equity is roughly value minus debt. Cash at closing reflects payoffs and settlement charges. Tax gain starts with amount realized minus adjusted basis. These figures may be very different, so a large loan payoff does not necessarily mean a small gain, and a large gain does not mean the same amount of cash is available.

Adjusted basis often begins with cost or another tax basis, then changes for capital improvements, depreciation, casualty items, prior exchanges, and other adjustments. Holding period, former personal use, passive losses, installment terms, property inside an entity, depreciation categories, and federal, state, or local tax rules affect the final reporting. Have the tax adviser calculate from documents rather than a remembered purchase price.

Missing depreciation records do not make depreciation disappear

Rental basis is generally reduced for depreciation. Current IRS guidance includes deductions previously allowed or allowable among basis reductions, so failing to claim a proper deduction does not necessarily preserve basis at sale. Depreciation-related gain can also receive treatment different from the rest of a long-term gain, including rules involving unrecaptured Section 1250 gain.

Ask the preparer to reconcile the building, land, improvements, appliances, and other fixed assets year by year. Flag cost-segregation studies, prior 1031 exchanges, partial dispositions, inherited or gifted interests, conversion from a residence, mixed personal use, and any years with missing returns. Those facts can change both basis and the character of gain.

Give the tax adviser a closing file, not a question from memory

Collect the purchase settlement statement, deed and entity records, depreciation and fixed-asset schedules, prior returns, capital-improvement invoices, insurance or casualty records, earlier exchange documents, refinance files, and the draft seller net. Refinance proceeds generally are not a new purchase basis. Keep repairs previously deducted separate from capital improvements so a cost is not counted twice.

For inherited, gifted, partnership-owned, or formerly personal-use property, the starting basis can depend on estate, gift, entity, and conversion records—not the amount the current owner remembers paying. If records are missing, identify that early so the adviser has time to reconstruct them before a closing deadline.

Use a 1031 exchange only if another real-estate plan fits your life

Under current federal rules, Section 1031 may defer gain when qualifying real property held for business or investment is exchanged for like-kind real property. It generally does not apply to property held mainly for sale, and U.S. real property is not like kind to real property outside the United States.

“Like kind” for qualifying real property is broader than “same building type,” so a rental house and qualifying land may potentially fit. The taxpayer, holding purpose, ownership structure, replacement asset, and value received still require professional analysis.

An exchange generally carries adjusted tax basis into the replacement property with adjustments; it does not simply wipe away tax. Cash or other non-like-kind value can create recognized gain, and personal property bundled with an unusual rental may need separate treatment.

If your real goal is to leave active landlording, say that before building the sale around an exchange. Deferral may be valuable, but acquiring another qualifying asset under a deadline can conflict with the reason you want out.

The exchange clock needs a plan before closing

A common deferred exchange uses a qualified intermediary so the seller does not receive or control the sale proceeds. Related parties and certain agents are not eligible to serve as the intermediary. Engage the tax and exchange team before the relinquished property closes; receiving proceeds from an ordinary closing can destroy the intended structure.

Current IRS instructions require replacement property in a deferred exchange to be identified within 45 days after transfer of the relinquished property. It generally must be received by the earlier of 180 days after that transfer or the tax-return due date, including extensions, for the transfer year.

The written identification must describe the property clearly and be delivered in a compliant way. Multiple-property identification, reverse or improvement exchanges, related parties, partnership interests, personal property, and disaster relief add complexity. Have the exchange professionals build and monitor the exact calendar.

Do not let a buyer, broker, or closing company substitute for your own tax advice. Their role in the transaction may be different from yours.

• Before closing: confirm the same-taxpayer structure, property use, intermediary, contract language, and replacement strategy.
• After transfer: deliver a compliant written identification within the applicable 45-day period.
• Acquire replacement property within the applicable exchange period and preserve the documents needed for Form 8824.

Compare cash you can use—not gross price alone

For each offer, estimate cash at closing after debt, commissions, credits, repairs, and settlement costs. Separately estimate realized gain, recognized gain, federal and state tax, and proceeds that must remain with an intermediary. A higher price can be less useful if it adds delay, breaks an exchange calendar, or depends on repairs and financing that increase the chance of failure.

Use ranges and label every tax figure as an estimate until the qualified adviser confirms it. Ask how seller financing, an entity sale, price allocation, closing date, assignment, installment terms, or an exchange affects the actual taxpayer. The buyer may share information, but should not be the seller's tax adviser.

Ask whether the tax plan serves the exit plan

Ask the adviser to confirm the taxpayer, adjusted basis, depreciation, likely character of gain, passive-loss effect, state and local filing, estimated payments, entity consequences, and the range of usable cash. If the property was inherited, gifted, received in an exchange, or ever used as your home, put that fact at the top of the question list.

Then test the strategy against your real objective. If you want no more tenants, debt, or property decisions, an exchange into another actively managed rental may be the wrong solution even when it defers tax. Ask about the consequences and tradeoffs of all realistic paths; tax efficiency is important, but it is not the only measure of a clean exit.
