Quick answer
What is an exchange fund?
An exchange fund is a private partnership where investors each contribute a different appreciated stock under IRC §721 and receive units in the pooled portfolio. Nobody pays capital gains tax at contribution. After about seven years each investor can take out a diversified basket of stocks, still carrying their original cost basis.
Key takeaways
- 01Contribution is tax-free under §721, but the tax is deferred, not erased: your old basis follows you into the basket.
- 02Expect a ~7-year hold, a 20% illiquid sleeve (usually real estate) and, at legacy sponsors, qualified purchaser status ($5M+ in investments).
- 03Reported fees run roughly 0.40%–0.95% a year, plus placement fees at some sponsors.
- 04An exchange fund diversifies but pays almost no income. An SPV like Embark keeps your stock and targets 10%+ income with a 3-year lock-up.
| Also called | Swap fund, §721 exchange fund |
|---|---|
| Tax at contribution | $0 (IRC §721) |
| Typical hold | About 7 years (§704(c) / §737) |
| Illiquid sleeve | At least 20% (usually real estate, §721(b) test) |
| Who can invest | Mostly qualified purchasers; some accredited-investor series |
| Typical minimum | $100K to $1M of stock, depending on sponsor |
| Income | Little to none; dividends of the pool |
The Short Answer
What is an exchange fund, in one paragraph?
An exchange fund is a private partnership that pools appreciated stock from many investors. Each investor contributes shares in kind and receives partnership units. Because the contribution is a partnership contribution under IRC §721, no capital gain is recognized on the way in. After roughly seven years, an investor can redeem for a pro-rata basket of the fund's holdings, which is diversified, still tax-deferred, and still carries the original low cost basis.

20%
Minimum share of non-securities assets, often real estate
Exchange funds solve one problem very well: turning a single-stock risk into index-like exposure without selling. They do not create income, they do not erase the gain (they defer it), and they lock your capital up for most of a decade. The rest of this guide covers each of those trade-offs, with the math.
How It Works
How does an exchange fund work, step by step?
Subscribe and contribute
You transfer eligible shares (in kind, usually by DTC or ACAT) into the partnership during a subscription window. You receive units at the fund's NAV. Tax: none under §721(a).
Hold the pooled portfolio
The fund holds the contributed stocks plus at least 20% in qualifying illiquid assets, usually leveraged real estate. Dividends flow through on a K-1, net of fees.
Redeem for a basket
You can take a pro-rata distribution of the fund's securities. The basket carries your original basis, so the deferred gain travels with it.
Sell, hold or gift
Selling basket shares triggers the deferred gain. Holding until death can reset basis under §1014. Gifting carries basis over to the recipient.
The seven-year clock comes from the partnership "mixing bowl" rules in §704(c)(1)(B) and §737, and the 20% illiquid sleeve comes from the investment-company test in §721(b). Both are explained in detail in Exchange Fund Rules: the 7-Year Hold and the 80/20 Test.
The Math
Is it better to sell or contribute a $5M position?
Take a $5M position with a $500K basis held by a California resident. Selling triggers a $4.5M long-term gain taxed at 20% federal, 3.8% net investment income tax and 13.3% state, about 37.1%. That is roughly $1.67M gone before a dollar is diversified.

Deferral is not elimination: The exchange-fund investor still owes tax on the original $4.5M gain when basket shares are eventually sold. The value comes from compounding the tax money for years, and from the chance to step up basis at death or give the shares to charity.
Who Qualifies
Who qualifies for an exchange fund, and which stocks are accepted?
| Requirement | Traditional sponsor funds | Newer platforms |
|---|---|---|
| Investor status | Qualified purchaser ($5M+ in investments) | Some accept accredited investors ($1M net worth ex-home, or income test) |
| Typical minimum | Reported ~$500K–$1M | As low as $100K (e.g. Cache, when allocation is open) |
| Eligible stock | Liquid large caps that fit the fund's target index | Same; popular tickers are often capped or wait-listed |
| Holding requirement | Usually you must have held the shares 12+ months | Same |
The sponsor needs the pool to look like its benchmark, so it limits how much of any one stock it accepts. Holders of the most crowded mega-cap names can find their ticker oversubscribed. The differences between the two investor tests are covered in Accredited Investor vs. Qualified Purchaser.
What It Costs
How much does an exchange fund cost?
Placement fee
A one-time fee on contribution at some sponsors, commonly reported around 1%.
Annual fees
Management plus servicing fees, reported between roughly 0.40% and 0.95% a year depending on the sponsor.
Real-estate sleeve
At least 20% of assets sit in illiquid property, often financed with debt. It can help or hurt returns, and it is not what you came for.
Seven-year illiquidity
Leave early and most funds hand back your original shares, so you lose the diversification you paid for.

Where Embark fits
An exchange fund diversifies you in seven years. What pays you in the meantime?
Many holders split the position. Run your ticker to see what the half you keep could target in income.
- Same §721 in-kind contribution as an exchange fund: $0 tax at contribution
- Keeps your stock's upside instead of pooling it with everyone else's
- Targets 10%+ annual income, with a 3-year lock-up instead of 7

Who offers exchange funds in 2026?
Exchange funds have historically been offered by private-bank and asset-management sponsors such as Eaton Vance (now part of Morgan Stanley Investment Management) and Goldman Sachs, mostly to qualified purchasers. Newer platforms such as Cache have lowered minimums and opened access to accredited investors, with funds benchmarked to indexes like the Nasdaq-100. We compare them, and SPV-based alternatives, in Eaton Vance Exchange Fund Alternatives.
Check current terms with the sponsor: Minimums, fees and eligibility change and are rarely published in full. Figures in this guide are commonly reported ranges, not offers. Read the private placement memorandum before committing.
Exchange Fund vs. SPV
What is the difference between an exchange fund and an SPV?
| Dimension | Exchange fund | Embark SPV |
|---|---|---|
| Tax at contribution | $0 (§721) | $0 (§721) |
| Goal | Diversify out of one stock | Earn income while keeping the stock |
| What you hold | Units in a pooled, multi-stock fund | Your own shares' economics inside an SPV |
| Income | Pass-through dividends, net of fees | Targets 10%+ a year |
| Lock-up | ~7 years for a diversified exit | 3 years, then continue or exit and receive your shares back |
| Upside of your stock | Diluted into the pool | Retained |
The two answer different questions. If the goal is to stop owning one company, an exchange fund does that. If the goal is to keep a stock you believe in and get paid while you hold it, an SPV fits better. Many holders split the position. The head-to-head lives in Exchange Funds vs. Embark.

FAQ
Frequently asked questions
Are exchange funds tax-free?
They are tax-deferred, not tax-free. Contributing stock is not a taxable event under IRC §721, but your original cost basis carries into the units and then into the basket you receive at exit. You pay the deferred gain when you sell those shares, unless the basis is stepped up at death.
How long do you have to stay in an exchange fund?
About seven years. Partnership anti-mixing-bowl rules (§704(c)(1)(B) and §737) can trigger the deferred gain if you receive other partners' property within seven years of contributing. Most funds therefore return only your original shares if you leave earlier.
What is the minimum for an exchange fund?
Traditional sponsor funds have reportedly required around $500K to $1M and qualified-purchaser status ($5M+ in investments). Some newer platforms accept accredited investors with minimums around $100K when they have capacity.
Do exchange funds pay income?
Only the dividends of the pooled stocks, net of fees, which is usually a low single-digit yield or less. They are built for diversification, not income.
What is the difference between an exchange fund and an SPV like Embark?
Both accept stock in kind under §721 with no tax at contribution. An exchange fund pools many investors' stocks to diversify you over about seven years. Embark's SPV keeps your stock's economics, targets 10%+ annual income, and has a three-year lock-up after which you can exit and receive your shares back.
Are exchange funds worth it?
They are worth considering when a single stock is a large share of your net worth, the unrealized gain is large, you want broad diversification, and you can leave the money untouched for about seven years. If you need income, liquidity or plan to sell within a few years, the fees and lock-up usually outweigh the benefit.
What are the downsides of exchange funds?
The main downsides are a roughly seven-year hold, a 20% illiquid sleeve, annual fees of about 0.40% to 0.95%, little or no income, no control over what other investors contribute, and tax that is deferred rather than eliminated.
Is an exchange fund the same as a 1031 exchange?
No. A 1031 exchange applies only to real property. Exchange funds use IRC §721, which lets you contribute property, including stock, to a partnership without recognizing gain.
