Multi-Member LLC Partnership Tax Planning and Allocation

As a multi-member LLC, you file partnership returns and each member pays SE tax on their distributive share. Proper operating agreements and allocation documentation are critical to withstanding IRS scrutiny.

Taxed as a partnership by default. The IRS treats a multi-member LLC as a partnership, requiring Form 1065 (partnership return) and Schedule K-1 for each member. The entity itself does not pay tax; income, deductions, and credits pass through to each member's personal return based on their allocation percentages.

The operating agreement controls tax allocations. Without an operating agreement -- or with a vague one -- the IRS defaults to equal allocation regardless of each member's actual contribution. Special allocations (giving one member more income or losses) must have "substantial economic effect" under IRC Section 704(b) to be respected. Badly drafted agreements trigger reallocation by the IRS.

Each member pays self-employment tax on their share. Unlike an S-corp, general partners and active LLC members owe SE tax on their entire distributive share. For a 50/50 LLC earning $200,000, each member pays SE tax on $100,000.

Guaranteed payments add complexity. Members who receive fixed compensation for services (similar to a salary) report guaranteed payments under Section 707(c), which are deductible by the partnership and taxable to the recipient -- including SE tax.

The pitfall: Partners often start businesses on a handshake and skip the operating agreement. When disputes arise or the IRS audits allocations, there is no documentation to support the tax positions taken.
