A 1031 Exchange Defers $35,000 in Tax — Worth $33,850 More After 10 Years Invested
We ran a $500,000 sale against a $300,000 adjusted basis, with $50,000 of accumulated depreciation, through the calculator. The total gain is $200,000 — $50,000 taxed as depreciation recapture at 25% ($12,500) and $150,000 taxed at a 15% capital gains rate ($22,500), for $35,000 in total tax. Without an exchange, that $35,000 goes to the IRS immediately. With one, it stays invested — and at a 7% return over 10 years, that deferred $35,000 grows into an extra $33,850 compared to having paid it out today.
The deferral itself isn’t the whole story
| Without exchange | With exchange, 10 years | |
|---|---|---|
| Tax paid now | $35,000 | $0 |
| That capital, invested at 7% for 10 years | — | grows to $68,850 |
| Extra wealth from deferral | — | $33,850 |
The exchange doesn’t make the $35,000 tax bill disappear — it’s still owed whenever the replacement property is eventually sold without another exchange. What the exchange actually buys is time: 10 years of that $35,000 compounding as investable capital instead of sitting in the Treasury. That compounding gain — not the deferral itself — is the real financial benefit, and it’s directly proportional to how long the deferral lasts.
The one way the deferred tax disappears for good
If the deferral chain continues until death rather than ending in a taxable sale, heirs receive a stepped-up basis — the property’s tax basis resets to its value at the date of death, and the previously-deferred gain (and the tax on it) simply evaporates. This is why serial 1031 exchanges held until death are a well-known estate-planning strategy among real estate investors, distinct from the pure timing-arbitrage benefit modeled here.
Where this framework doesn’t apply
- The property is your personal residence. 1031 exchanges only apply to investment or business-use real property — a primary home falls under Section 121’s separate home-sale exclusion instead.
- You can’t realistically meet the 45-day/180-day deadlines. These are strict and essentially unforgiving; missing either one converts the entire transaction into a fully taxable sale.
- You plan to eventually cash out and spend the proceeds, not hold until death. The deferral eventually ends in a taxable event in that case — plan for that future tax bill rather than treating the deferral as permanent.
- The replacement property is worth less than the relinquished one. Any shortfall (“boot”) is immediately taxable, partially defeating the exchange’s purpose.
What to actually do
- Engage a qualified intermediary before closing the sale — a 1031 exchange must be structured in advance, not added after the fact.
- Start identifying replacement properties immediately once the sale closes; the 45-day clock doesn’t pause for anything.
- Confirm the replacement property’s value and financing will meet or exceed the relinquished property’s, to avoid a taxable “boot.”
- Talk to a tax professional about your specific depreciation schedule and adjusted basis before finalizing the numbers — see how tax-gain harvesting interacts with capital gains brackets for a related capital-gains-timing strategy.
- Think through your eventual exit — another exchange, a taxable sale, or holding until death for a stepped-up basis — since each has very different long-term tax consequences.

Quick answers
What is a 1031 exchange?
A Section 1031 like-kind exchange lets an investor sell one investment property and roll the proceeds into another, deferring capital gains tax and depreciation recapture tax, as long as a replacement property is identified within 45 days and the exchange closes within 180 days, with all proceeds reinvested.
Does a 1031 exchange eliminate the tax, or just delay it?
It defers, not eliminates. The deferred tax is still owed whenever the replacement property is eventually sold without another exchange. The one exception: if the property passes to heirs, they receive a stepped-up basis, which can eliminate the deferred tax entirely rather than just delaying it.
How is depreciation recapture taxed differently from the rest of the gain?
The portion of the gain attributable to depreciation claimed during the holding period is taxed as unrecaptured §1250 gain at up to 25% — higher than the 0%, 15%, or 20% long-term capital gains rates that apply to the rest of the gain.
What are the strict deadlines for a 1031 exchange?
45 days from closing the sale to identify a replacement property, and 180 days total to close on it. Both deadlines are essentially unforgiving — missing either disqualifies the exchange and makes the entire transaction taxable.
