What Is Non-Pro Rata? Section 751, S-Corps, and Redemptions

A non-pro rata distribution is a payout of cash or property from a business where at least one owner receives a share that doesn’t match their ownership percentage. If you hold 40% of a company but walk away with 60% of a particular asset, that distribution is non-pro rata. The arrangement is legal when the governing documents allow it, but the IRS generally treats the uneven split as a deemed exchange between the owners, which means tax consequences can appear even when no one thinks a sale took place.

Pro Rata vs. Non-Pro Rata

Pro rata means “in proportion.” Two 50/50 partners splitting $100,000 pro rata each receive $50,000. Shareholders holding 60%, 25%, and 15% receive exactly those percentages of any pro rata payout.

A non-pro rata distribution breaks that pattern on purpose. Take the same 50/50 partnership: one partner receives real estate worth $80,000, and the other receives $80,000 in cash and equipment. The totals balance, but the specific assets each partner leaves with don’t match a straight 50% slice of every item. That deliberate mismatch is what makes the distribution non-pro rata, and it’s why the tax code analyzes it differently.

Authorization Is Required

You can’t simply hand one owner more than their share. A partnership or LLC operating agreement has to permit unequal distributions, and a corporation needs the transaction to fit within an authorized corporate action such as a stock redemption. Without a legal basis in the governing documents, the distribution isn’t valid in the first place.

The Deemed Exchange: Where the Tax Hits

A standard pro rata partnership distribution generally doesn’t trigger gain unless the cash distributed exceeds a partner’s basis in their partnership interest.¹ Non-pro rata distributions lose that protection.

The IRS analyzes the transaction in two hypothetical steps. First, the partners are treated as receiving their proportionate shares of all partnership assets. Second, they’re treated as exchanging assets among themselves until the actual distribution pattern is achieved. That second step is a taxable event. No partner consciously sold anything to anyone, but the IRS treats them as if they did, and gain or loss is recognized on the deemed exchange.

Hot Assets Under Section 751

Section 751 creates the most painful surprises in this area. It targets “hot assets,” which include unrealized receivables and inventory that has appreciated beyond 120% of its adjusted basis. These assets produce ordinary income when sold, and Congress didn’t want partners to use uneven distributions to convert ordinary income into capital gain.²

When a distribution changes a partner’s share of hot assets, Section 751(b) overrides the normal nonrecognition rules and recharacterizes the transaction as a sale between the partner and the partnership.¹ The gain or loss is measured by the difference between the partner’s adjusted basis in the relinquished property interest and the fair market value of what they received.³ The gain is ordinary income, not capital gain. A partner who thought they were receiving a tax-free distribution of equipment can end up owing ordinary income tax on a deemed sale of their share of the partnership’s receivables.

The S-Corporation Problem

S-Corporations sit in awkward territory. To qualify for S-Corp status, a corporation can have only one class of stock, meaning all shares must carry identical rights to distributions and liquidation proceeds.⁴ At first read, that seems to prohibit non-pro rata distributions outright.

The regulations are more nuanced. They focus on the rights granted by the governing documents, not on what actually happens in a given year. If the articles and bylaws give all shareholders identical distribution rights, the corporation doesn’t create a second class of stock just because an actual distribution comes out uneven.⁵ Courts have agreed that disproportionate distributions alone don’t terminate the S election as long as the governing documents aren’t amended to create unequal rights.

That isn’t the same as “no consequences.” The IRS can recharacterize an excess distribution as compensation, a loan, or some other taxable item. And if the governing documents themselves give certain shareholders preferential rights, you now have two classes of stock and a terminated S election.

Related Non-Pro Rata Mechanics in Partnerships

Partnerships and LLCs taxed as partnerships operate under Subchapter K, which is deliberately flexible about dividing income, losses, deductions, and credits in ways that don’t match ownership percentages.⁶ Two patterns show up alongside non-pro rata distributions and are worth distinguishing from them.

Special Allocations

A special allocation assigns a specific item of income, loss, or deduction to a partner in a proportion different from the general profit-sharing ratio. Two equal partners might agree that one receives 80% of the depreciation deductions from a particular property. The IRS respects the allocation only if it has “substantial economic effect.”⁷ That requires real economic effect (the allocation actually changes what the partner receives on liquidation, supported by proper capital accounts) and substantiality (a reasonable possibility the allocation meaningfully changes dollar outcomes apart from tax savings). If the test fails, the IRS can reallocate the items based on each partner’s actual economic interest.⁸

Contributed Property Under Section 704(c)

Some non-pro rata allocations aren’t optional. When a partner contributes property whose fair market value differs from its tax basis, Section 704(c) requires the partnership to allocate the built-in gain or loss to the contributing partner. If you contribute a building worth $500,000 that you bought for $200,000, the $300,000 of pre-contribution appreciation can’t be shifted to your partners when the partnership eventually sells. If the contributed property is later distributed to a different partner within seven years, the contributing partner must recognize the built-in gain or loss as if the property had been sold.⁸

Stock Redemptions Under Section 302

A stock redemption is inherently non-pro rata because the corporation isn’t buying the same proportion of shares back from everyone. The tax question is whether the IRS treats the payment as a sale of stock (capital gains rates) or a dividend (ordinary income). Section 302 provides the tests for sale-or-exchange treatment: the redemption must completely terminate the shareholder’s interest, be “substantially disproportionate,” or be “not essentially equivalent to a dividend.”⁹

The substantially disproportionate test has a specific math threshold. After the redemption, the shareholder’s percentage of voting stock must drop below 80% of what it was before, and the shareholder must own less than 50% of total voting power. Failing every Section 302 test recharacterizes the full payment as a dividend, which is usually the worse outcome.⁹

Divorce and Estate Settlements

Non-pro rata divisions appear constantly outside the business context. The underlying idea flips: instead of giving one owner more than their percentage, each party receives assets worth the same total value but composed of different specific items.

Divorce

One spouse might receive the family home while the other receives the investment accounts. Each gets an equal share of the marital estate, but the specific assets are divided unevenly. Property transfers between spouses incident to divorce are generally nontaxable, and the receiving spouse takes over the transferring spouse’s original tax basis.¹⁰ That basis carryover matters more than people realize. If your spouse bought stock for $50,000 and it’s now worth $200,000, you inherit the $50,000 basis and owe capital gains tax on $150,000 of appreciation when you eventually sell. Settlement negotiations that look only at face value overstate what the lower-basis side is actually receiving.

Estates

Estates routinely make non-pro rata distributions. A will might leave the family business to one child and the investment portfolio to another, with both children treated as equal beneficiaries. Inherited assets generally receive a stepped-up basis equal to fair market value on the date of death.¹¹ A beneficiary who inherits stock the decedent bought for $10,000 but was worth $100,000 at death gets a $100,000 basis and owes little or no capital gains tax on an immediate sale.¹² The stepped-up basis applies whether the estate distribution is pro rata or non-pro rata. If the executor elects the alternate valuation date for estate tax purposes, basis is set as of that date instead.

Reporting and Getting the Math Right

For partnership non-pro rata distributions, the partnership has to calculate each partner’s proportionate share of hot and cold assets before and after the distribution, then determine the extent of any deemed exchange. The analysis flows through the partnership return and onto the affected Schedules K-1. When a position involves an allocation or distribution method that isn’t straightforward, filing Form 8275 as a disclosure statement puts the IRS on notice and can help avoid accuracy-related penalties.¹³

Getting the math wrong isn’t a minor inconvenience. Missing the deemed exchange means underreporting income, with accuracy-related penalties and interest on top. A professional valuation is often necessary to establish fair market value for the distributed assets, and those appraisals run from a few hundred dollars for simple assets to $20,000 or more for complex business interests.
