Multi-Member LLC Tax Treatment: Partnership Rules for Business Co-Owners
When two or more people form an LLC, the IRS treats it as a partnership by default. The LLC itself pays no income tax. Instead, it files Form 1065 (U.S. Return of Partnership Income) and issues a Schedule K-1 to each member showing their share of income, deductions, and credits. Each member reports their K-1 amounts on their personal return. This pass-through structure avoids double taxation but creates complexity around self-employment tax, special allocations, and the prohibition on members being employees.
Multi-member LLC (partnership) tax rules:
Filing requirement:
- Form 1065 due March 15 (or September 15 with extension)
- Late filing penalty: $255/month per partner for returns due in 2026 ($245 for returns due in 2025), up to 12 months
- Example: a 3-member LLC filing 4 months late: $255 x 3 x 4 = $3,060
Self-employment tax on K-1 income:
- General partners (which includes most LLC members who are active in the business): SE tax applies to their distributive share of ordinary business income
- Limited partners: SE tax generally applies only to guaranteed payments, not distributive shares (but the IRS has proposed regulations that could change this for LLC members)
- A managing member of a multi-member LLC is almost always treated as a general partner for SE tax purposes
- SE tax rate: 15.3% (12.4% Social Security up to $176,100, 2.9% Medicare on all income)
Members Can’t be employees:
- Under Rev. Rul. 69-184, a partner can’t be an employee of the partnership
- This means: no W-2, no payroll withholding, no employer-provided health insurance (on a pre-tax basis)
- Members receive guaranteed payments (like salary) or distributions, both reported on K-1
- Guaranteed payments are deductible to the LLC and subject to SE tax to the member
- This is one of the key reasons multi-member LLCs often elect S-Corp status
Operating agreement provisions that affect tax:
- Profit/loss allocation ratios (can differ from ownership percentages, but must have substantial economic effect under IRC 704(b))
- Guaranteed payments to managing members
- Capital account maintenance rules
- Distribution waterfall (how cash is distributed)
- Special allocations of specific items (depreciation, tax credits)
Basis tracking:
- Each partner tracks their outside basis in the partnership interest
- Basis starts with contributions and increases for income allocations and additional contributions
- Basis decreases for loss allocations, distributions, and deductions
- Losses are deductible only to the extent of basis
Distributions:
- Generally NOT taxable if they don’t exceed the partner’s basis
- Distributions exceeding basis are taxed as capital gains
- Partners pay tax on their distributive share regardless of whether they actually receive a distribution (phantom income); the operating agreement should include a “tax distribution” provision requiring the partnership to distribute enough cash to cover each partner’s estimated tax liability
S-Corp election for a multi-member LLC:
- File Form 2553 to elect S-Corp status
- Members become shareholders and can be employees (receiving W-2 salary)
- Eliminates SE tax on distributions above the reasonable salary
- Requires equal distribution rights per share (no special allocations)
- All members must consent to the election
How do the tax rules work for a 50/50 two-member LLC?
How are partnership distributions taxed?
Cash distributions from a partnership are generally tax-free to the extent of your outside basis in the partnership interest. Distributions exceeding your basis trigger capital gain (typically long-term if you have held the interest for more than one year). Unlike S-Corp distributions, partnership distributions don’t require a separate payroll/salary analysis because partners already pay self-employment tax on their distributive share of partnership income. Property distributions are generally tax-free to both the partner and the partnership, with the partner taking a carryover basis in the property. Guaranteed payments (fixed amounts for services or capital use) are deductible by the partnership and taxable to the receiving partner as ordinary income, regardless of whether the partnership has profits.
How is the self-employment tax calculated?
Self-employment tax is 15.3% on net self-employment income up to the Social Security wage base ($168,600 in 2024), then 2.9% on income above that threshold. Net self-employment income is calculated as 92.35% of your Schedule C net profit (the 7.65% reduction approximates the employer-half FICA deduction that W-2 workers receive). You deduct half of the self-employment tax on Schedule 1 of Form 1040, which reduces your AGI and income tax but does not reduce the SE tax itself. The additional Medicare tax of 0.9% applies to combined wages and self-employment income exceeding $200,000 ($250,000 married filing jointly). This makes the effective rate on high-income self-employment earnings 16.2%.

What is a guaranteed payment and how is it taxed?
Guaranteed payments under IRC 707(c) are amounts paid to a partner for services or capital use that are determined without regard to partnership income, similar to a salary or interest payment. They’re deductible by the partnership as an ordinary business expense, reducing the remaining income allocated to all partners including the recipient. The receiving partner reports guaranteed payments as ordinary income subject to self-employment tax, unlike distributive share income which may include capital gains or other specially-allocated items. Guaranteed payments must be reported in the partner’s tax year that includes the end of the partnership’s tax year in which the partnership deducted them, which can create timing mismatches for fiscal-year partnerships.
