A partnership's tax return looks like an income statement until you notice that capital gains, charitable contributions, and Section 179 are missing. They were pulled out and listed separately on each K-1, because each partner applies their own tax rules. The exam tests whether you can sort items into the right bucket.
A partnership is a pass-through entity. It files Form 1065 as an information return, reporting income, deductions, and gains, but paying no federal tax. Each partner receives a Schedule K-1 with their distributive share and reports each item on their own return. The partnership computes and classifies; the partner pays.
The first question on every partnership problem: which items are netted into ordinary business income, and which are separately stated? Get the buckets right and the rest is arithmetic.
KEY: Form 1065 line 22 is ordinary business income (loss). Schedule K (and each partner's K-1) breaks out separately stated items. Nothing on the partnership return calculates tax, that happens on each partner's 1040.
Common mistakes
- Netting separately stated items into ordinary income. Partnership P&L lists $50,000 LTCG and $20,000 charitable contributions in operating data. Candidate subtracts charitable and adds capital gain while computing line 22, arriving $30,000 too high. Correct: pull both OUT first. Trap: the wrong number that includes capital gain in ordinary income is often the second-largest distractor.
- Treating guaranteed payments as distributions. Partner receives a $60,000 guaranteed payment and a 25% share of $200,000 remaining ordinary income. Candidate reports only the $50,000 distributive share, treating the guaranteed payment as a basis-reducing distribution. Correct: $60,000 + $50,000 = $110,000. Trap: $50,000.
- Forgetting that guaranteed payments reduce partnership ordinary income before allocation. Partnership has $300,000 of net income before considering a $100,000 guaranteed payment to A. Candidate allocates the $300,000 across all partners, then layers the guaranteed payment on top of A's share.
Bottom line
- Form 1065 is an information return; the partnership pays no tax. Each partner's K-1 carries their distributive share of every income, deduction, gain, loss, and credit item.
- Separately stated items retain character at the partner level: capital gains/losses, Section 1231, dividends, portfolio interest, charitable contributions, Section 179, foreign taxes, tax-exempt interest, and rental income. Everything else nets into ordinary income on K-1 line 1.
- Guaranteed payments reduce partnership ordinary income and are ordinary income to the partner regardless of basis; they are subject to self-employment tax.
- Section 704(b) allocations require substantial economic effect: capital accounts per the regs, liquidation per capital accounts, and either deficit restoration or qualified income offset. Failed allocations are reallocated by partners' interests.
Exam shortcut
When you see a partnership P&L on the exam, run the bucket sort first: highlight every item that is separately stated (capital gains, dividends, interest, Section 1231, Section 179, charitable contributions, foreign taxes, tax-exempt income) and only THEN compute ordinary business income on what's left. This single discipline catches the most common trap on Form 1065 questions.
