When a partnership splits into two or more partnerships, federal tax law under IRC Section 708 and Treasury Regulation 1.708-1(d) overrides whatever legal steps the partners take under state law and recasts the split into one of two deemed transaction patterns. The partnership division tax treatment that results controls which entity keeps the original’s tax identity, whether any partner recognizes gain, how asset basis carries into the new entities, and what each resulting partnership has to file. Picking the wrong structure can trigger unexpected taxable gain, lose favorable basis positions, or force the business to start over with a new EIN and new elections.1Office of the Law Revision Counsel. 26 U.S. Code 708 – Continuation of Partnership
Which Resulting Partnership Continues the Original
Section 708(b)(2)(B) uses what practitioners call the “more than 50% test.” A resulting partnership is treated as a continuation of the prior partnership if its partners collectively held more than 50% of the capital and profits interests in the original entity.1Office of the Law Revision Counsel. 26 U.S. Code 708 – Continuation of Partnership
Three outcomes are possible. If exactly one resulting partnership clears the threshold, that entity alone continues the original. If more than one clears it, each is a continuation. If none does, the prior partnership terminates entirely and every resulting entity is new.
Continuation status matters because the continuing partnership keeps the original Employer Identification Number, the established tax year, and the accumulated tax elections. A resulting partnership that fails the test applies for a new EIN and starts fresh.2Internal Revenue Service. When To Get a New EIN It cannot rely on prior accounting method elections or depreciation schedules from the old partnership. For a business with significant depreciable assets or favorable accounting methods in place, losing continuation status is costly.
The Two Methods the IRS Recognizes
Federal tax law doesn’t care what sequence of state-law steps the partners follow. The IRS recharacterizes the division into one of two forms spelled out in Regulation 1.708-1(d)(3).3eCFR. 26 CFR 1.708-1 – Continuation of Partnership
Assets-Over Method
Assets-Over is the default. If the partners don’t follow the specific state-law steps required for Assets-Up treatment, the IRS applies Assets-Over automatically. Under this form, the continuing partnership is deemed to contribute a portion of its assets and liabilities to one or more new recipient partnerships in exchange for interests in those new entities. The continuing partnership then distributes those newly acquired interests to the departing partners in partial or complete liquidation of their interests.
Assets-Up Method
Assets-Up reverses the flow. The continuing partnership distributes assets directly to the partners who are leaving, and those partners then contribute the distributed assets to a new partnership in exchange for interests in it. For the IRS to respect this form, every asset that ends up in a particular recipient partnership must actually pass through the hands of the partners who will own that entity under local law. The partners’ ownership is transitory, but the steps have to happen.
Assets-Up is harder to execute because the legal mechanics have to track the deemed tax mechanics precisely. It can offer advantages worth the complexity, particularly around the mixing bowl rules discussed below.
What About Just Transferring Interests?
Partners sometimes consider having departing members transfer their interests in the old partnership to a new entity. The regulations don’t recognize this as an independent form for divisions. A transaction structured this way is recharacterized as Assets-Over for tax purposes.3eCFR. 26 CFR 1.708-1 – Continuation of Partnership
Where Partners Get Taxed by Accident
A division leans on two nonrecognition rules. Section 721 shields contributions of property to a partnership in exchange for an interest.4Office of the Law Revision Counsel. 26 U.S. Code 721 – Nonrecognition of Gain or Loss on Contribution Section 731 shields distributions, except that a partner recognizes gain when the cash or deemed cash distributed exceeds their adjusted basis in the partnership interest.5Office of the Law Revision Counsel. 26 U.S. Code 731 – Partners and Distributions Three situations commonly crack that protection open.
Liability Shifts
Under Section 752, any decrease in a partner’s share of partnership liabilities is treated as a cash distribution to that partner, and any increase is a cash contribution.6Office of the Law Revision Counsel. 26 U.S. Code 752 – Treatment of Certain Liabilities A division always reallocates liabilities. If a partner’s share drops far enough that the deemed cash distribution exceeds outside basis, that partner owes tax on the excess. This is where most accidental gain recognition happens, and it needs modeling before closing.
Hot Assets
Section 751 treats unrealized receivables and substantially appreciated inventory as “hot assets.” When a distribution shifts a partner’s share of hot assets disproportionately, the transaction is recast as a sale between the partner and the partnership, producing ordinary income.7eCFR. 26 CFR 1.751-1 – Unrealized Receivables and Inventory Items Assets-Up is especially exposed because assets flow to partners as distributions before being re-contributed.
The Mixing Bowl Rules
Two provisions target situations where the economic benefit of appreciated contributed property ends up with someone other than the contributor within seven years. Section 704(c)(1)(B) forces the contributing partner to recognize gain if the contributed property is distributed to a different partner within seven years of the original contribution.8Office of the Law Revision Counsel. 26 U.S. Code 704 – Partner’s Distributive Share Section 737 works the other direction: if the contributing partner receives a distribution of other property within seven years, they recognize gain up to the lesser of the distribution’s fair market value over their basis, or their net precontribution gain.9Office of the Law Revision Counsel. 26 U.S. Code 737 – Recognition of Precontribution Gain in Case of Certain Distributions to Contributing Partner
This is one of the main reasons the Assets-Over versus Assets-Up choice matters. Under Assets-Over, the continuing partnership contributes assets to the new entity and the resulting distribution of interests to partners can trigger Section 737. Under Assets-Up, the distribution goes directly to partners and may trigger Section 704(c)(1)(B) if contributed property ends up with a non-contributor. Choosing well requires mapping every partner’s contribution history against the specific assets being moved.
How Asset Basis Carries Through
Under Assets-Over, the new partnership takes a carryover basis in the assets it receives, equal to the original partnership’s adjusted basis in those assets.10Office of the Law Revision Counsel. 26 U.S. Code 723 – Basis of Property Contributed to Partnership Partners who receive interests take a substituted basis derived from their existing outside basis in the original partnership. Section 704(c) built-in gain or loss on contributed property carries over as well, so the original contributor remains on the hook for that built-in amount.
Under Assets-Up, partners first receive a distribution of assets. The basis of distributed assets is generally the partnership’s adjusted basis, capped at the partner’s outside basis reduced by any money received in the same transaction.11GovInfo. 26 U.S. Code 732 – Basis of Distributed Property Other Than Money When partners then contribute the assets to the new partnership, that entity takes a basis equal to each partner’s adjusted basis at the time of contribution. The result can differ from the carryover basis under Assets-Over, sometimes favorably and sometimes not, depending on the gap between inside and outside basis.
What Happens to a Section 754 Election
A Section 754 election, once made, requires the partnership to adjust the basis of its property whenever a distribution occurs or a partnership interest is transferred.12Office of the Law Revision Counsel. 26 U.S. Code 754 – Manner of Electing Optional Adjustment to Basis of Partnership Property In a division, the deemed contributions and distributions under both methods can trigger basis adjustments under Sections 734(b) and 743(b).13Internal Revenue Service. FAQs for Internal Revenue Code (IRC) Sec. 754 Election and Revocation
The continuing partnership’s existing 754 election carries forward. Non-continuing partnerships are new entities and start without one; they must affirmatively elect if they want basis adjustments. One important limit: the IRS will not approve a revocation of a 754 election if the primary purpose is to avoid a downward basis adjustment on partnership assets.13Internal Revenue Service. FAQs for Internal Revenue Code (IRC) Sec. 754 Election and Revocation Partners hoping to drop an unfavorable election as part of the restructuring need to plan around this.
Holding Period for the New Interest
A partner who acquires an interest in a resulting partnership through the division doesn’t necessarily start a fresh holding period. Under Regulation 1.1223-3, a partner can have a divided holding period when portions of an interest were acquired at different times or in exchange for different types of property.14eCFR. 26 CFR 1.1223-3 – Rules Relating to the Holding Periods of Partnership Interests The fraction used for each portion is based on the fair market value of that portion divided by the fair market value of the entire interest, measured immediately after the transaction.
This matters for capital gains. If a partner sells the interest in a resulting partnership within a year of the division, part of the gain may still qualify as long-term because the holding period tacks from the original interest. Getting the calculation wrong can convert preferential long-term treatment into ordinary short-term rates.
What Each Partnership Has to File
Every partnership involved in the division, continuing or new, files Form 1065.15Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income The return is due on the 15th day of the third month after the end of the partnership’s tax year, which is March 15 for calendar-year partnerships. An automatic six-month extension is available by filing Form 7004.16Internal Revenue Service. Publication 509 (2026), Tax Calendars
The continuing partnership attaches a statement to its Form 1065 for the division year identifying all resulting partnerships by name and EIN. Non-continuing partnerships file a first return covering the period from the division date through the end of their initial tax year. If the division terminates the prior partnership entirely, that entity files a final short-year return ending on the division date.
Each partnership issues a Schedule K-1 to every partner, reporting that partner’s share of income, deductions, and credits.15Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income In the division year, some partners receive K-1s from more than one entity and use them to report the division’s consequences on their individual returns.
Late filing carries a penalty of $245 per partner for each month or partial month the return is overdue, up to 12 months.17Internal Revenue Service. Information About Your Notice, Penalty and Interest A division often creates filing obligations that didn’t exist the year before, so the exposure runs higher than in a normal year. Building the compliance calendar before closing is worth the effort.
