Imagine you own a building worth $1 million with a tax basis of $200,000. You'd love to pull cash out of it without paying tax on $800,000 of gain. So you and a few friends form an LLC, you contribute the building, and a month later the partnership distributes $600,000 of cash back to you. Contributions to a partnership are tax-free under Section 721. Distributions of cash are generally tax-free up to your basis. Problem solved?
Not even close. The IRS saw this move coming decades ago, and Section 707(a)(2)(B) — the "disguised sale" rule — exists specifically to stop it. If you contribute property and the partnership hands you cash on the way in or shortly after, the tax code can collapse the two steps into a single taxable sale. The label on the paperwork does not matter. The economics do.
Disguised sales are one of the most misunderstood traps in partnership taxation. They catch ordinary, well-meaning business owners who have no intention of gaming anything — a real estate developer pulling out reimbursement for predevelopment costs, a founder rolling an asset into a joint venture, a family contributing property to a new LLC. This guide explains how the rule works, when the two-year presumption flips against you, the exceptions that can save the transaction, and what you need to disclose.
What a Disguised Sale Actually Is
A disguised sale happens when two transfers, viewed together, look like a purchase and sale even though they were dressed up as a contribution and a distribution.
The mechanics require two pieces:
- A partner transfers money or property to the partnership.
- The partnership transfers money or other consideration back to that partner (or to another partner).
When those transfers, taken together, are "properly characterized as a sale or exchange," Section 707(a)(2)(B) recharacterizes them. Instead of a tax-free contribution under Section 721 followed by a tax-free distribution, you get a sale: the contributing partner recognizes gain, and the partnership takes a cost basis in the property it is treated as having bought.
The rule is not limited to cash going out the door. The "consideration" flowing back to the partner can include the partnership assuming debt that was attached to the contributed property. That is where many otherwise routine real estate deals go sideways.
The Two-Year Presumption: Timing Is Everything
The regulations under Section 707 (specifically Reg. 1.707-3) create two timing presumptions that determine which way the burden of proof points.
Transfers within two years of each other are presumed to be a disguised sale. If you contribute property and receive cash within a 24-month window in either direction, the IRS presumes the two events are a sale unless the facts and circumstances clearly establish otherwise. You are guilty until proven innocent.
Transfers more than two years apart are presumed not to be a disguised sale. Stretch the gap beyond two years and the presumption flips in your favor — the IRS must clearly establish that the transfers were a sale.
Two years is not a magic shield. It is a presumption, not a rule. The IRS can still attack a transaction outside the window if the facts show the distribution was effectively guaranteed at the time of contribution — for example, if the partnership agreement obligates the distribution regardless of partnership performance. But timing dramatically shifts who has to do the convincing, and that practical difference is enormous in an audit.
The factors that "clearly establish" a sale (or rebut one) include whether the timing and amount of the later transfer were determinable with reasonable certainty at the time of contribution, whether the partner has a legally enforceable right to the transfer, and whether the partner's continued ownership of a partnership interest is subject to entrepreneurial risk.
How the Deemed Sale Amount Is Computed
When a disguised sale is triggered, you do not necessarily sell the entire property. You sell a slice of it.
The portion treated as sold equals the ratio of the consideration received to the property's fair market value at transfer.
Example. You contribute property worth $1,000,000 with a tax basis of $200,000. In a related transaction the partnership distributes $450,000 of cash to you.
- Percentage deemed sold: $450,000 ÷ $1,000,000 = 45%
- Sale proceeds: $450,000
- Basis allocated to the sale: 45% × $200,000 = $90,000
- Recognized gain: $450,000 − $90,000 = $360,000
The remaining 55% of the property is treated as a genuine tax-free contribution under Section 721, carrying over $110,000 of basis. The partnership's basis in the property becomes the $450,000 it is treated as paying plus the $110,000 carried over on the contributed portion.
The takeaway: pulling cash out of a contributed asset does not give you a free pass on basis recovery. You recognize gain on the sold fraction immediately, in the year of the transaction.
Debt: The Quiet Trigger Most People Miss
Cash is the obvious form of consideration. Debt relief is the sneaky one.
When you contribute property subject to a mortgage, the partnership's assumption of that debt reduces your share of the liability. To the extent your liability share drops, you are treated as receiving consideration — which can count toward a disguised sale. This is why a contribution with no cash changing hands can still produce a taxable sale.
The regulations soften this by distinguishing qualified from nonqualified liabilities:
- A qualified liability generally includes debt incurred more than two years before the transfer, or debt incurred to acquire or improve the contributed property. When property is contributed subject to a qualified liability and there is no other disguised-sale consideration, the assumption is largely not treated as sale proceeds.
- A nonqualified liability — for example, a cash-out refinancing taken shortly before the contribution — is treated as disguised sale consideration to the extent the contributing partner's share of that liability decreases.
A classic mistake: a partner mortgages a property a few weeks before contributing it, pockets the loan proceeds, and assumes the assumption will be ignored. It will not. That recent borrowing is a nonqualified liability, and shifting it to the partnership is consideration.
The Exceptions That Can Rescue the Deal
Section 707's regulations carve out several categories of payments that are presumed not to be disguised sale proceeds. Knowing them is the difference between a clean structure and a surprise tax bill.
Reimbursement of Preformation Expenditures
This is the most valuable exception for real estate and development deals. A partnership can reimburse a partner — without disguised sale treatment — for capital expenditures the partner made on the property (or on partnership organization and syndication costs) during the two years before the transfer.
There is a cap: the reimbursed amount generally cannot exceed 20% of the property's fair market value at the time of transfer. The 20% cap is waived if the property's FMV does not exceed 120% of the partner's adjusted basis — meaning lightly appreciated property gets more room.
There is also a debt-funding trap. If a partner funded those preformation expenditures with a qualified liability, and economic responsibility for that borrowing shifts to other partners when the partnership assumes it, the preformation reimbursement exception does not cover the portion funded by that shifted debt. You cannot get reimbursed tax-free for spending you never economically bore.
Guaranteed Payments and Preferred Returns
A reasonable guaranteed payment for the use of a partner's capital — determined without regard to partnership income — is presumed not to be part of a sale. The same protection applies to a reasonable preferred return on capital. These are compensation for letting the partnership use your money, not a buyout of your property.
Operating Cash Flow Distributions
Ordinary distributions of operating cash flow — distributions that track the partner's share of the partnership's net cash flow from operations — are presumed not to be sale proceeds. Importantly, these distributions keep their protected status even if the partnership holds the cash and distributes it in a later year.
Disclosure: When You Have to Tell the IRS
The regulations include a disclosure rule (Reg. 1.707-8). You generally must disclose a transfer on the partnership return when:
- A contribution and a related transfer occur within two years of each other and you are not treating them as a disguised sale, or
- Transfers occur more than two years apart and you are treating them as a disguised sale.
In both cases you are telling the IRS, "the presumption points one way and I'm reporting the other way." Disclosure is made on a statement attached to the return. Failing to disclose does not change the substantive answer, but it removes a layer of protection and can make the position look like something you were hiding.
Common Mistakes to Avoid
- Assuming the two-year window is a hard wall. It is a presumption. A predetermined, low-risk distribution can be a disguised sale even outside the window.
- Ignoring debt. No cash moving does not mean no consideration. Liability shifts are consideration.
- Refinancing right before a contribution. Recent borrowing creates a nonqualified liability and is the fastest way to manufacture a disguised sale.
- Over-claiming preformation reimbursements. Watch the 20%-of-FMV cap and the two-year lookback, and remember the qualified-liability funding trap.
- Skipping disclosure. If you are reporting against the presumption, disclose it.
- Treating the LLC label as protection. Most multi-member LLCs are partnerships for tax purposes; these rules apply to them in full.
Why Clean Records Make This Survivable
Every part of a disguised sale analysis depends on facts you must be able to prove years later: the date a liability was incurred, the fair market value and basis of contributed property, the exact timing of every distribution, which expenditures were capital versus operating, and how each was funded. When an examiner asks whether a 2026 distribution was "related" to a 2024 contribution, a contemporaneous, well-organized ledger is your best evidence.
This is also why deal timelines matter so much. The two-year presumption is measured in dates, and the difference between a transfer landing on day 720 versus day 740 can flip the entire burden of proof. Tracking contribution dates, liability origination dates, and distribution dates with precision is not bookkeeping nicety — it is tax risk management.
