Why It Matters
You can't do a 1031 exchange without a QI. IRS regulations (Treas. Reg. §1.1031(k)-1) require that you never receive, pledge, borrow, or otherwise gain access to the sale proceeds during the exchange. The moment those funds become available to you — even briefly — you've had "constructive receipt," the exchange is blown, and you owe tax on the full gain. The QI creates legal distance: money flows from closing to the QI, then from the QI to your replacement property closing — you never touch it.
Your attorney, accountant, and financial advisor are all off-limits — IRS rules disqualify anyone who's served as your agent within the prior two years. Engage a genuinely independent QI before your relinquished property closes.
At a Glance
- What it is: An independent third party that holds your 1031 exchange proceeds and acquires the replacement property on your behalf
- Required by: Treas. Reg. §1.1031(k)-1 — no QI means no valid exchange
- The core rule: You must never touch, pledge, or access the funds during the exchange period
- Who can't be a QI: Your attorney, CPA, financial advisor, or anyone who served as your agent in the prior 2 years
- Timing: Engage the QI before your relinquished property closes — not after
- Typical cost: $750–$2,000 for a simple single-property exchange
How It Works
The constructive receipt problem. If sale proceeds hit your bank account — even for a single day — the IRS considers you to have received them, triggering capital gains on the full amount regardless of your reinvestment intent. The QI structure solves this: at closing, the title company wires proceeds directly to the QI's segregated account, not to you. You never had access, so you never had constructive receipt. The exchange rules are satisfied from day one.
How the engagement works. Before your relinquished property closes, you sign an Exchange Agreement with the QI. The QI is assigned your rights under the replacement property purchase contract — making the QI technically the buyer on your behalf. At closing, proceeds go straight to the QI's segregated account. The QI holds those funds while your exchange period runs, then uses them to complete the replacement purchase and deed the property to you.
Who qualifies — and who doesn't. The IRS bars any "disqualified person" from serving as a QI: the taxpayer themselves, related parties, and anyone who served as your agent within the prior two years. That two-year lookback covers attorneys, CPAs, investment advisors, and real estate brokers — anyone in a professional relationship with you. The QI must be a true stranger to your affairs. The 1031 exchange advisor who structures your strategy is separate from the QI that holds the funds — one advises, the other executes.
Real-World Example
Sandra owns a 12-unit apartment building in Phoenix she bought for $780,000 twelve years ago. She sells it for $1,840,000, creating a $1,060,000 gain she'd like to defer.
Six weeks before closing, Sandra engages a QI. The QI is assigned her rights in the contract on a $2,100,000 Scottsdale office-retail building. At the Phoenix closing, the title company wires $1,832,000 in net proceeds directly to the QI's segregated account — Sandra never sees the money.
On day 91, Scottsdale closes. The QI wires $2,100,000 to the seller (Sandra brought the $268,000 gap from a refinance) and title goes to Sandra. Full deferral on the $1,060,000 gain — no boot because replacement value exceeds proceeds received. Total QI fee: $1,450.
Had the Phoenix proceeds landed in Sandra's account first, the entire $1,060,000 would have been taxable that year. A $1,450 fee to avoid a six-figure tax bill.
Pros & Cons
- Required for a valid exchange — Not optional insurance; the QI is the legal mechanism that makes deferral possible under IRS regulations
- Segregated account protection — Proceeds must sit in a dedicated account separate from the QI's operating funds — no commingling with other clients' exchanges
- Eliminates constructive receipt risk — Proceeds flowing to the QI before closing satisfies the IRS safe harbor with a clean paper trail
- Handles multi-property complexity — A QI can manage identification across multiple replacement properties, holding and releasing funds as each closes
- Low cost relative to the tax deferred — At $750–$2,000 for a simple exchange, the fee is a rounding error compared to the capital gains bill it avoids
- Must be engaged before closing — No retroactive fix; if proceeds hit your account before the QI is in place, the exchange is over
- QI insolvency risk — Your money is in the QI's hands; if the QI goes bankrupt before your replacement closing, you could lose both the deferral and the funds
- No deal-structure advice — The QI executes the mechanics; whether your replacement qualifies as like-kind or your numbers work is a separate conversation with a tax advisor
- No timeline extensions — Miss the 45-day ID window or the 180-day close and the funds come back taxable
- Disqualification traps — Investors who use one attorney or advisor for everything may find that person disqualified, requiring advance planning before each exchange
Watch Out
Select your QI on financial security, not price. A discount QI that goes bankrupt before your replacement closing means losing the deferral and potentially the funds. Confirm fidelity bond coverage, E&O insurance, and FDIC-insured segregated accounts before signing. Established national firms are worth the premium.
The two-year lookback applies even to inactive relationships. An attorney you used 18 months ago still can't be your QI. Run through your full professional network — attorney, CPA, broker, planner — before engaging anyone, and exclude any entity they control.
A partial exchange still requires a QI. If you're keeping some proceeds as taxable boot, the QI must hold everything and release only the boot portion to you at closing. You can't skip the QI because you're not rolling the full amount.
Engage the QI before the closing date, not the morning of. The Exchange Agreement must execute before deed transfer. Give the title company at least a few business days to process the wire instructions to the QI's account.

The Takeaway
A Qualified Intermediary is the linchpin of any 1031 exchange — without one in place before closing, you have a taxable sale. The job is straightforward: hold your proceeds, keep them away from you, and deploy them at your replacement closing. The strict independence rules exist because the IRS won't let you use your own people to hold funds you can still reach. Engage a financially sound QI with verifiable insurance well before your relinquished property closes, and treat the fee as the cheapest line item in any deal where the deferred tax runs into six figures.
