Partnership Taxation

Partnership taxation is a cornerstone of business law and a frequent focus on the Bar Exam. Unlike corporations, partnerships are flow-through entities, meaning the entity itself pays no income tax. Instead, all items of income, deduction, gain, loss, and credit pass through to the individual partners, who report these items on their personal tax returns. Understanding this conduit principle is essential for advising clients on business structure, tax planning, and compliance.

Core Concept 1: Formation and Initial Basis

A partnership forms when two or more persons join together to carry on a trade or business, contributing money or property and expecting to share profits. For tax purposes, the key event is the contribution of property to the partnership in exchange for a partnership interest.

Upon formation, the partnership generally does not recognize gain or loss. The contributing partner's initial outside basis in their partnership interest is equal to the cash plus the adjusted basis of any property they contributed, plus any gain recognized on the contribution (e.g., from relief of debt). This is the partner's personal tax investment in the partnership.

Simultaneously, the partnership takes a carryover basis in the contributed property—the same basis the partner had—to prevent a step-up in value at formation. This creates a critical distinction: outside basis (the partner's basis in their interest) versus inside basis (the partnership's basis in its assets). These two bases are independent but start aligned upon formation.

*Example: Alex contributes land with a fair market value (FMV) of $100,000andanadjustedbasisof$40,000, plus $10,000cash,fora50$50,000 ($40,000+$10,000). The partnership's inside basis in the land is $40,000.*

Core Concept 2: Operations and Allocations

During operations, the partnership's taxable income or loss is computed at the entity level, much like an individual's return. This amount, along with all separate items (like charitable contributions or capital gains), is then allocated to the partners according to the partnership agreement.

However, the agreement's allocations must have substantial economic effect to be respected for tax purposes. This complex set of rules ensures that tax allocations align with the actual economic burdens and benefits. The analysis involves maintaining capital accounts according to specific rules, a requirement to restore deficit capital accounts upon liquidation, and following a strict distribution waterfall. If allocations lack substantial economic effect, they are re-allocated according to the partners' interest in the partnership, a profit-sharing ratio determined by all facts and circumstances.

Each partner's outside basis is adjusted annually. It increases by the partner's share of income and additional contributions, and decreases by the partner's share of losses and distributions (but not below zero). This basis tracking is vital because a partner can only deduct losses up to their outside basis at the end of the year.

Core Concept 3: Distributions and Dispositions

Distributions from a partnership to a partner are generally non-taxable events, acting as a return of the partner's investment. A cash distribution reduces the partner's outside basis dollar-for-dollar. If the cash distributed exceeds the partner's outside basis, the excess is treated as gain from the sale of the partnership interest (a taxable event).

Distributions of property (other than cash) follow a similar deferral principle. The partner typically takes a carried basis in the distributed property equal to the partnership's inside basis, and reduces their outside basis by that same amount. This ensures gain is deferred until the partner later sells the distributed property.

The ultimate disposition is the sale of a partnership interest. This is treated as the sale of a capital asset, generally resulting in capital gain or loss. The gain is often ordinary income to the extent it is attributable to unrealized receivables and inventory items (so-called "hot assets"), a rule designed to prevent partners from converting ordinary income into capital gain.

Core Concept 4: Partner Self-Employment Tax

A crucial operational consideration is the self-employment (SE) tax. For general partners, their entire distributive share of the partnership's business income is typically subject to SE tax, which funds Social Security and Medicare. This is true even if the income is not actually distributed. Limited partners, however, are generally only subject to SE tax on guaranteed payments for services. This distinction creates significant planning implications for partners seeking to manage their SE tax liability while maintaining their desired level of management involvement.

Common Pitfalls

Mistake 1: Confusing Inside and Outside Basis. A classic Bar Exam trap is to apply partnership-level (inside) basis rules to a partner-level (outside) basis question, or vice versa. Remember: outside basis belongs to the partner and determines loss deductibility and gain on distributions. Inside basis belongs to the partnership and determines gain/loss on partnership asset sales.

Mistake 2: Assuming the Partnership Agreement is Always Respected. It is easy to forget the substantial economic effect requirements. An allocation of a large loss to a high-tax-bracket partner might be desirable, but if the partnership agreement does not properly maintain capital accounts and include a deficit restoration obligation, the IRS will re-allocate the loss according to the partners' interest in the partnership, potentially ruining the intended tax outcome.

Mistake 3: Misapplying Distribution Rules. Treating all distributions as taxable income is incorrect. The default rule is non-recognition. Your first step should always be to reduce the partner's outside basis by the cash distributed. Taxable gain arises only when cash exceeds the outside basis. For property distributions, remember the carryover basis rule to preserve the gain for recognition later.

Mistake 4: Overlooking Self-Employment Tax for General Partners. When calculating a partner's tax liability, failing to add SE tax on top of ordinary income tax is a critical error. A partner's tax burden includes both, and SE tax applies to the allocable share of business income, not merely to draws or guaranteed payments.

Summary

• Partnerships are flow-through entities; the partnership files an informational return (Form 1065), but the partners pay tax on their allocable shares of income.
• A partner's outside basis is key for deducting losses and avoiding gain on distributions. It starts with the basis of contributed property, is increased by income, and decreased by losses and distributions.
• Allocations of income and loss under the partnership agreement must have substantial economic effect, governed by capital account maintenance rules, to be valid for tax purposes.
• Cash distributions are generally tax-free to the extent of the partner's outside basis; excess cash triggers capital gain.
• General partners owe self-employment tax on their full distributive share of business income, while limited partners generally do not.
• Gain on the sale of a partnership interest may be recharacterized as ordinary income to the extent it is attributable to the partnership's "hot assets" (unrealized receivables and inventory).
