Partnership Taxation for a Multi-Member LLC

How it works

A multi-member LLC is taxed as a partnership by default. No election is needed: the check-the-box regulations attach partnership status the moment a second member joins (Treas. Reg. 301.7701-3(b)(1)(i)). It can instead elect C corporation treatment (Form 8832) or S corporation treatment (Form 2553); absent either, Subchapter K, sections 701 through 761, governs how the business and its owners are taxed.

The partnership itself is not a taxpayer. It computes its income, files Form 1065 as an information return, and passes the result through to the partners on Schedule K-1 (IRC sec. 701), whether or not cash was distributed that year.

What Subchapter K lets you do that an S corporation cannot

Three features set a partnership apart from an S corporation. The first is special allocations: a partnership agreement can share a specific item, depreciation, a particular gain, in a ratio that departs from ownership percentages, if the allocation has substantial economic effect, a demanding test covered below. An S corporation cannot do this; every item follows stock ownership pro rata.

The second is debt. A partner's share of partnership liabilities adds to outside basis (IRC sec. 752(a), (b)), so a partner can deduct losses funded by the partnership's own borrowing rather than cash contributed. An S corporation shareholder gets no equivalent: entity-level debt does not increase stock basis, no matter who guaranteed it.

The third is how a working owner gets paid. A partnership can make a guaranteed payment, fixed compensation set without regard to earnings (IRC sec. 707(c)). It shows up on the K-1, not a W-2, since a partner cannot also be a W-2 employee of the same partnership (Rev. Rul. 69-184), and it is ordinary income subject to self-employment tax. An S corporation owner is paid the opposite way, as W-2 compensation through payroll.

What this looks like in Florida

Florida has no individual income tax (Fla. Const. art. VII) and no entity-level tax on the partnership, so the only income tax cost here is federal, paid once, at the partner level, true of any pass-through entity in the state. The LLC still registers and stays current with Sunbiz and files an annual report, covered in my Florida LLC annual report guide. Reemployment tax is a payroll tax on wages paid for employment (Fla. Stat. sec. 443.131), so it applies only once the LLC has actual W-2 employees; a guaranteed payment or distributive share is not a wage.

Self-employment tax on active members

A general partner's distributive share of trade or business income is net earnings from self-employment, subject to self-employment tax (IRC sec. 1402(a)), as is a guaranteed payment for services. The combined rate applies to 92.35% of net earnings: 12.4% Social Security up to an annually adjusted wage base, plus 2.9% uncapped Medicare, plus an additional 0.9% surtax above a fixed higher-income threshold. A true limited partner's distributive share is excluded (IRC sec. 1402(a)(13)), though a guaranteed payment for services performed is not; whether an active LLC member can claim that exclusion is contested, addressed below.

Who this applies to

Three things have to all be true.

• Two or more members. A single-member LLC is a disregarded entity, taxed like a sole proprietorship, not a partnership (Treas. Reg. 301.7701-3(b)(1)(ii)). A second member makes it a partnership automatically, no filing required. More on the disregarded-entity line in my LLC basics guide.
• Any business taxed as a partnership. Not limited to an LLC: a general partnership, a limited partnership, an LLP, and a multi-member LLC are all taxed under Subchapter K (IRC sec. 761(a)). A narrow carve-out lets certain investment arrangements elect out, built for passive co-ownership, not an operating business.
• No corporate or S election in effect. Once a Form 8832 or Form 2553 election is filed and effective, Subchapter K stops applying. Whether that trade makes sense is a separate question, covered in my Florida S corporation guide.

One eligibility wrinkle: a partner's distributive share of qualified business income feeds the section 199A deduction, but a guaranteed payment does not count as qualified business income to the recipient, though it still reduces the partnership's own qualified business income (IRC sec. 199A(c)(4)(B)). OBBBA, the 2025 tax law, made 199A permanent and, starting with 2026 returns, added a smaller minimum deduction for a taxpayer with some active qualified business income (IRC sec. 199A(i)).

This page is about how the operating partnership itself is taxed. Whether it should also sit inside a broader structure separating it from appreciating assets is a related question, covered in my entity structuring guide.

What it requires

The substantial economic effect test

An allocation is respected only if it has substantial economic effect, which under Treas. Reg. 1.704-1(b)(2) requires three things at once: capital accounts maintained as the regulation requires; liquidating distributions that follow those balances; and either a deficit restoration obligation or a qualified income offset. Miss one and the economic-effect prong fails.

A second prong, substantiality, catches an allocation that is transitory: one designed to move a deduction to whichever partner needs it that year, then reversed the next, so the partners' capital accounts end up substantially where they would have been without the allocation while their combined tax bill comes out lower.

When an allocation fails either prong, it is reallocated according to the partners' interest in the partnership, meaning the IRS, or the Tax Court, decides what it should have been (IRC sec. 704(b); Treas. Reg. 1.704-1(b)(3)), a worse outcome than never having tried the allocation.

Filing and basis mechanics

Form 1065 is due March 15 for a calendar-year partnership, with a six-month extension on Form 7004. The late-filing penalty (IRC sec. 6698) runs per partner, per month up to a twelve-month cap under section 6698(a), material even for a two-person LLC. Each K-1 must report tax-basis capital, not just book capital.

Outside basis rises for contributions and a partner's share of income, and falls for distributions and losses, never below zero. A partner's share of liabilities is part of that number: recourse debt follows economic risk of loss (Treas. Reg. 1.752-2); nonrecourse debt follows a separate, tiered allocation. An increase in liability share is a deemed contribution; a decrease is a deemed distribution that can trigger gain (IRC sec. 752(a), (b)).

A loss must then clear the at-risk, passive activity, and excess business loss rules, the last made permanent by OBBBA, before a partner can use it. Basis alone does not guarantee a deduction.

Formation and the basis step-up election

Forming the LLC is the easy part: Articles of Organization, an EIN, and partnership classification attaches automatically at the second member. What matters is whether the operating agreement contains the capital-account language the substantial economic effect test demands. Organizational costs get their own treatment, covered in my startup and organizational costs guide, as does the accounting method the partnership adopts, in my cash method guide.

A section 754 election (IRC sec. 754) lets the partnership adjust inside basis to match a transferee partner's outside basis, made in a written statement with a timely Form 1065, extensions included, and revocable only with the IRS's consent. A sale or death produces a section 743(b) adjustment; certain distributions trigger a parallel section 734(b) adjustment. Even without an election, a 743(b) adjustment becomes mandatory once a transfer carries a built-in loss over $250,000 (IRC sec. 743(b), (d)).

One warning belongs with that machinery. Subchapter K is not a listed or reportable transaction in itself, but it is a frequent host for them. Using 754, 743(b), and 734(b) adjustments to shift basis among related parties without economic substance runs into Treas. Reg. 1.6011-18, which designates related-party partnership basis adjustments as transactions of interest and makes them reportable. That regulation is on its way out rather than settling in: Notice 2025-23 announced Treasury's intent to remove it and granted immediate relief from the Section 6707A penalty for participants, and a removal proposal was published in March 2026, though no final removal rule had issued as this was written. A structure in that shape still has to be screened against those rules and handled with specialist counsel, not treated as ordinary basis planning.

What you need to document

A compliant operating agreement

Capital account and liquidation language satisfying the substantial economic effect test: how accounts are maintained, that liquidating distributions follow positive balances, and a deficit restoration obligation or qualified income offset. The document that decides whether a special allocation survives.

An outside basis schedule for each partner

Updated every year for contributions, income, distributions, losses, and each partner's share of liabilities, alongside the 704(b) book capital accounts and the tax-basis capital Schedule K-1 now requires. Reconstructing any of these after the fact is close to never having kept them.

The debt allocation analysis

Documentation of who bears the economic risk of loss on recourse debt, plus the profit-sharing computation behind a nonrecourse allocation. Debt basis is only as strong as the paper behind it.

The section 754 election statement, if one is made

Filed with a timely Form 1065, governing every future transfer and distribution until revoked with the IRS's consent.

Something in writing for every guaranteed payment

A guaranteed payment is fixed without regard to partnership income. Once a payment starts moving with profit, it needs to be documented and treated as a distributive share instead.

Where it goes wrong

Special allocations collapsing under section 704(b)

This is the most common failure I see. An operating agreement allocates a loss disproportionately to the highest-bracket partner, but has no deficit restoration obligation or qualified income offset, or nobody actually keeps the capital accounts it describes. On examination, the allocation is reallocated according to the partners' interest in the partnership, and the negotiated benefit disappears (Treas. Reg. 1.704-1(b)(3)). Substantiality catches a related mistake: an allocation real on paper but shifted back the following year, with no lasting effect.

Disguised sales

A contribution followed by a related distribution within two years is presumed a disguised sale (Treas. Reg. 1.707-3). A leveraged distribution soon after a contribution is exactly the pattern that draws the presumption, and rebutting it after the fact is harder than structuring around it up front.

A guaranteed payment that is actually contingent on income is not a guaranteed payment, whatever the agreement calls it. It is a distributive share, and mislabeling it changes both when it is deductible and how it interacts with the 199A calculation.

Self-employment tax, the live battleground

The limited partner exception looks simple until an LLC tries to use it. A passive limited partner's distributive share in a state-law limited partnership is excluded from self-employment tax; whether an active LLC member, who has no such state-law status at all, gets the same treatment is genuinely unsettled. In Soroban Capital Partners LP v. Commissioner, 161 T.C. No. 12 (2023), followed in T.C. Memo. 2025-52, the Tax Court applied a functional test: an active partner is not a limited partner for this purpose, regardless of label. The Fifth Circuit did go the other way in Sirius Solutions LLLP v. Commissioner on January 16, 2026, reading the term by state-law status. That opinion no longer stands. On August 12, 2026 the panel granted rehearing, withdrew it, and substituted a new one, now captioned K Alain, L.L.L.P. v. Commissioner, holding that the original public meaning of limited partner is a partner who plays no significant role in managing or running a business, and vacating and remanding so that question can be applied to the partners at issue. That is a functional reading. The clean circuit split this section used to describe is therefore gone: both the Tax Court and the Fifth Circuit now look at what the partner actually does, and differ on how the test is framed rather than on whether the label decides it.

For an active Florida LLC member, I treat the distributive share as self-employment income. Calling that interest a limited-partner interest to avoid the tax carries real litigation exposure, and I do not put it on a return without documented passivity and the client's informed agreement to carry it.

Late filing and late K-1s carry their own cost regardless of the above: the IRC sec. 6698 penalty accrues per partner, per month, capped at twelve months per return by section 6698(a), regardless of how few owners the LLC has.

Missing the basis step-up election window

The section 754 election has to go on a timely return, extensions included. Missing that window is not automatically fatal, and the relief is better than most people expect: a late section 754 election is on the automatic 12-month extension list in Treas. Reg. 301.9100-2(a)(2), which needs no letter ruling and carries no user fee. Only past that twelve months does it become discretionary 301.9100-3 relief with a fee attached. That longer road is the process I describe in my late election relief guide, but relief is discretionary and comes with an IRS user fee and a real delay. Making the election on time is always the better plan.

A situation where this comes up

The pattern I see most often is a two-person operating LLC: one partner contributes most of the cash, the other contributes some capital plus the work of running the business day to day. A guaranteed payment for the working partner pays for that work regardless of profitability, with the remaining profit split between them. If the money partner signed the personal guarantee on the LLC's line of credit, that partner, not the one running the business, gets the outside basis for that debt, and that matters the day the business needs to deduct a loss.

What usually has to change is the paperwork, not the structure. The LLC was formed with a template operating agreement that splits profits and losses by ownership and stops there: no deficit restoration obligation, no qualified income offset, nobody keeping the capital accounts it never described how to keep. None of that matters while the business is simply profitable. It matters the moment anyone wants a special allocation, or the year the business loses money and a partner needs to know whether the loss is usable. The other recurring conversation is the active member who wants a limited-partner label to avoid self-employment tax. I do not build a return around that label unless the member's actual role supports it. The question is litigated rather than settled, and since the Fifth Circuit withdrew its January 2026 opinion in August 2026 and substituted a functional reading, there is no circuit in which a bare state-law label has carried the day.
