Multi-Member LLC For partnerships and co-founders.

A multi-member LLC is a Limited Liability Company with two or more owners. By default, the IRS treats it as a partnership and requires filing Form 1065 annually. The Operating Agreement is the most important internal document, defining how members vote, share profits, handle additions and departures, and resolve disputes.

Formal Definition

A multi-member LLC (MMLLC) is a Limited Liability Company with two or more owners. By default, it is taxed as a partnership and files Form 1065 with the IRS, issuing Schedule K-1 to each member for their share of income, deductions, and credits.

In plain English

Here is what that actually means.

Multi-member LLCs are the typical structure for co-founders going into business together. Each member contributes capital (cash, equipment, services, or sweat equity), receives a percentage ownership in the LLC, and shares in profits and losses based on the Operating Agreement.

The Operating Agreement is critical. It defines capital contributions, ownership percentages (which can differ from contribution percentages), profit and loss allocation (which can differ from ownership), management structure (member-managed vs manager-managed), voting rights, transfer restrictions, buy-sell provisions, and dissolution procedures.

Tax-wise, multi-member LLCs are pass-through entities. The LLC files Form 1065 annually but does not pay income tax. Each member receives a Schedule K-1 showing their share of LLC items, and reports those on their personal Form 1040. Self-employment tax applies to active members' shares.

FAQ

Common questions.

How is a multi-member LLC taxed?
By default, as a partnership. The LLC files Form 1065 annually but pays no income tax itself. Each member receives Schedule K-1 and reports their share of LLC income on their personal Form 1040.
What is the deadline for Form 1065?
March 15 (calendar-year LLCs). A 6-month extension to September 15 is available via Form 7004. Missing the deadline triggers a $220-per-month-per-member penalty.
How are profits split?
By the Operating Agreement. Typically proportional to ownership percentages, but the Operating Agreement can specify different allocations (e.g., guaranteed payments to working members, preferred returns to capital).
Can members get paid a salary?
Active members typically receive "guaranteed payments" rather than salary. Guaranteed payments are deductible to the LLC and treated as ordinary income to the member. If the LLC has elected S-Corp tax treatment, members who are also officers can be paid W-2 wages.
How do members add or leave the LLC?
Per the Operating Agreement. Common patterns: right of first refusal (other members buy first), buy-out formula (predetermined price for departing members), unanimous consent to admit a new member.
What if members disagree?
The Operating Agreement should specify dispute resolution (typically mediation, then arbitration, before litigation). Without clear procedures, deadlocks can force dissolution.
Can a multi-member LLC have foreign members?
Yes. Multi-member LLCs can have non-US members. Tax reporting is more complex; the LLC may need to withhold tax on income allocated to foreign partners and file Form 8804/8805.
Can a multi-member LLC elect S-Corp tax treatment?
Yes, if all members are eligible: US individuals (or certain trusts), 100 members maximum, single class of stock/interest. Many MMLLCs cannot elect S-Corp because they have entity members or foreign members.
How is self-employment tax handled?
Active members (those who materially participate) pay self-employment tax on their share of LLC ordinary income. Passive members generally do not, though this is fact-specific and often litigated.
Can a married couple form a single-member LLC?
In community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin), a husband-wife LLC can elect to be treated as a single-member LLC. In other states, a husband-wife LLC is a multi-member LLC by default.
