How to Read a K-1: A Partner's Guide to Schedule K-1 (Form 1065)

Every partner in a partnership or multi-member LLC receives a Schedule K-1 each year. It reports the partner's share of income, deductions, credits, and other items from the partnership. The numbers on the K-1 flow directly from the operating agreement's allocation provisions. Understanding what each section means helps you connect the K-1 to your operating agreement and your individual tax return.

What Is a K-1?

Schedule K-1 (Form 1065) is the document a partnership uses to report each partner's share of the partnership's tax items. The partnership itself does not pay income tax. Instead, it passes income and deductions through to the partners, and each partner reports their share on their individual return.

The K-1 is divided into three main sections: partner information, partner's share of income and deductions, and partner's share of liabilities.

Part I and Part II: The Basics

The top of the K-1 identifies the partnership and the partner. It includes the partner's ownership percentage and their share of profit, loss, and capital. These percentages should match what the operating agreement says, unless the agreement provides for special allocations that differ from ownership percentages.

It also shows the partner's capital account analysis. Beginning balance, contributions, allocations of income or loss, distributions, and ending balance. This should tie to the capital account maintenance provisions in the operating agreement.

Part III: Income, Deductions, and Credits

This is where the numbers live. The key boxes include:

Box 1: Ordinary business income or loss. The partner's share of the partnership's net ordinary income. This is the core operating result.

Box 2: Net rental real estate income or loss. For real estate partnerships, this is often the most relevant box. Rental income and expenses, including depreciation, flow through here.

Box 5: Interest income. The partner's share of interest earned by the partnership.

Box 8: Net short-term capital gain or loss. Short-term capital gains from assets held one year or less.

Box 9a: Net long-term capital gain or loss. Long-term capital gains from assets held more than one year. In a real estate sale, this is where the capital gain portion appears.

Box 11: Other income. Items that do not fit in the standard boxes, including cancellation of debt income.

Box 13: Deductions. The partner's share of itemized deductions from the partnership, including charitable contributions.

Box 19: Distributions. Cash and property distributed to the partner during the year. This is separate from the income allocation. You can have income in Box 1 or 2 without a corresponding distribution in Box 19, which is how phantom income appears.

The Liability Section

The K-1 also reports the partner's share of partnership liabilities, broken into recourse, nonrecourse, and qualified nonrecourse categories. These amounts directly affect the partner's outside basis, which determines how much loss they can deduct.

The operating agreement's allocation provisions and any personal guarantees drive how liabilities are split among partners.

How Does the Operating Agreement Connect?

Every number on the K-1 traces back to the operating agreement. The allocation method determines income and loss splits. The waterfall determines distributions. The capital account provisions drive the capital account analysis. The liability allocation follows the profit-sharing and risk-sharing provisions.

If a number on your K-1 looks unexpected, the operating agreement is the first place to look. The Taxes and Operating Agreements overview walks through the full range of provisions that drive the K-1.
