If you’re sitting on a $500,000-plus investment property and considering a sale, the number you need to know before anything else is not the asking price. It’s your unrealized capital gain — and what the IRS will take from it the moment you close without a plan.
Section 1031 of the tax code exists precisely for this situation. A properly executed like-kind exchange lets you defer federal capital gains taxes — potentially indefinitely — by rolling proceeds from one investment property into another. For investors who do it right, it’s one of the most powerful wealth-preservation tools in real estate. For investors who miss a deadline by a day, it collapses entirely.
A 1031 exchange has no margin for error on its two hard deadlines. Miss either one, and the full capital gain becomes taxable in the year of sale — no exceptions, no extensions.
The Two Rules That Govern Everything
The entire 1031 exchange framework runs on two sequential deadlines, both of which begin the moment you close on the sale of your relinquished property:
- 45-Day Identification Rule: Within 45 calendar days of closing, you must formally identify potential replacement properties in writing to your Qualified Intermediary (QI). You can name up to three properties regardless of value, or more under specific percentage rules. There are no extensions for illness, travel, or market conditions.
- 180-Day Closing Rule: You must close on one or more of your identified replacement properties within 180 calendar days of the original sale — or by your tax return due date if earlier. If your sale closed April 9, 2026, your replacement closing deadline is October 6, 2026.
Both deadlines are statutory and run concurrently — Day 180 is not 180 days after your 45-day window closes. Planning your exchange means working backward from these dates before you list your property.
The table below assumes a sale closing on April 9, 2026:
| 1031 Timeline | Action Required | 2026 Example Deadline |
| Day 0 | Close on relinquished (sold) property | Sale closes: April 9, 2026 |
| Days 1–45 | Identify replacement property in writing | Deadline: May 24, 2026 |
| Days 1–180 | Close on replacement property | Deadline: October 6, 2026 |
| Ongoing | Document intermediary chain of title | No gaps in QI custody |
| Post-close | Integrate with estate & step-up basis plan | Annual review recommended |
What a Qualified Intermediary Does — And Doesn’t Do
A Qualified Intermediary is legally required in any 1031 exchange. The QI holds your sale proceeds in escrow between transactions, ensuring you never take constructive receipt of the funds — which would immediately trigger taxes. Without a QI, there is no exchange.
What a QI does not do is advise you. A QI is a transaction facilitator, not a fiduciary. They won’t tell you whether the replacement property fits your financial plan, whether you’re over-leveraging, or whether a different tax strategy would serve you better. Some QIs maintain relationships with real estate brokers and may suggest properties — with commissions flowing accordingly.
A fee-only fiduciary advisor fills the gap a QI cannot:
| Qualified Intermediary Only | Fee-Only Fiduciary Advisor + QI |
| Holds funds in escrow only | Coordinates QI + guides the full strategy |
| No investment or tax advice | Tax-optimized property selection guidance |
| May refer you to commission brokers | No property commissions — ever |
| Exchange closes; tax planning ends | Integrates with estate plan & step-up basis |
| Flat transaction fee, narrow scope | Flat-fee planning across your whole picture |
Beyond the Exchange: Step-Up Basis and Estate Planning
The most underutilized aspect of 1031 planning isn’t the exchange itself — it’s what happens at death. Under current tax law, heirs who inherit appreciated real estate receive a stepped-up cost basis to the property’s fair market value at the date of inheritance. Decades of deferred capital gains can be wiped clean at death.
For investors who plan to hold and exchange through retirement, a 1031-to-death strategy is a legitimate and widely used approach: defer taxes through a series of exchanges, hold until death, and allow heirs to inherit with a clean basis. This transforms a deferred tax liability into a permanent elimination — but only if the estate plan is structured properly around it.
Integrating your 1031 strategy with your estate plan requires coordinated advice across tax, investment, and legal lines. A fee-only fiduciary acts as the quarterback — not a product seller with a stake in which property you choose.
We also work with clients on depreciation recapture exposure, installment sale alternatives, and Delaware Statutory Trust (DST) options for investors who want 1031 deferral without active property management.
