Operating a partnership can provide flexibility for small business owners, but it also comes with specific federal tax filing requirements. One of the most important responsibilities is preparing and filing Form 1065, U.S. Return of Partnership Income.

Partnerships generally use Form 1065 to report the business's income, deductions, gains, losses, credits, and other tax information. The partnership generally does not pay federal income tax on its ordinary business income at the entity level. Instead, taxable items are generally passed through to the partners, who report their respective shares on their individual or other applicable tax returns.

Understanding how Form 1065 works can help partners stay organized and avoid filing problems.

What Is Form 1065?

Form 1065, U.S. Return of Partnership Income, is the federal information return used by partnerships to report their financial and tax information to the IRS.

The form generally reports items such as:

Business income and losses

Gains and losses

Deductible expenses

Credits

Partner information

Distributions and other partnership-related tax items

Form 1065 generally does not determine a single federal income tax bill for the partnership in the same way that a corporate income tax return does.

Instead, the partnership calculates and reports the partners' distributive shares of relevant tax items. Each partner generally receives a Schedule K-1 (Form 1065) showing that partner's share of income, deductions, credits, and other items.

How Do Form 1065 and Schedule K-1 Work Together?

Think of Form 1065 as the partnership's overall tax report.

For example, suppose four individuals own a partnership. The partnership reports its business activity on one Form 1065. The return then allocates the appropriate tax items among the partners.

Each partner generally receives a separate Schedule K-1.

The K-1 identifies the partner's share of items that may need to be reported on the partner's own tax return.

The partnership must generally prepare and provide a Schedule K-1 to each person who was a partner during the tax year. The K-1 is generally due to the partner by the same date the partnership return is required to be filed.

This pass-through structure means the partnership's income can be taxable to the partners even when the partnership does not distribute all of the cash to them.

Who Must File Form 1065?

Generally, a domestic partnership must file Form 1065 unless an exception applies, including situations where the partnership had neither income nor expenditures treated as deductions or credits for federal income tax purposes.

Businesses that may have a Form 1065 filing requirement include:

General Partnerships

Businesses operated by two or more partners under a partnership arrangement generally file Form 1065.

Limited Partnerships

Limited partnerships generally report their partnership activity using Form 1065.

Limited Liability Partnerships

An LLP classified as a partnership for federal tax purposes generally files Form 1065.

Multi-Member LLCs

A domestic LLC with two or more members is generally classified as a partnership for federal income tax purposes unless it elects to be treated as a corporation.

Certain Foreign Partnerships

Some foreign partnerships may have a U.S. filing requirement, particularly when they have U.S.-source income or income effectively connected with a U.S. trade or business. Special rules apply to foreign partnerships.

Certain other organizations and joint ventures may also have Form 1065 requirements depending on their circumstances.

Understanding the Main Sections of Form 1065

Form 1065 contains multiple schedules and supporting information. The exact forms required can vary depending on the partnership's activities and circumstances.

Page 1: Partnership Information and Business Income

The first page generally contains basic information about the partnership, including:

Legal name and address

Employer identification number

Principal business activity

Business code

Date the business started

Accounting method

Tax year

Whether the return is initial, final, amended, or otherwise subject to a special filing status

It also reports the partnership's trade or business income and deductions.

Depending on the business, this may include gross receipts, returns and allowances, cost of goods sold, wages, rent, depreciation, and other deductible business expenses.

A partner or authorized individual generally signs the return on behalf of the partnership.

Schedules B and Other Information

Form 1065 also includes questions about the partnership's ownership, accounting, foreign activities, elections, and other circumstances.

The partnership may also need to identify its partnership representative, who has an important role under the centralized partnership audit rules.

The questions in this section help determine which additional schedules and forms may be required.

Schedule K

Schedule K summarizes the partnership's distributive share items for all partners.

Depending on the partnership's activities, these items can include:

Ordinary business income or loss

Rental income

Interest income

Dividends

Capital gains and losses

Charitable contributions

Section 179 deductions

Self-employment-related items

Tax credits

Foreign transactions

Other separately stated tax items

The amounts reported on Schedule K generally flow to the partners through their individual Schedule K-1 forms.

Schedule K-1

Each partner generally receives a Schedule K-1 (Form 1065).

The K-1 identifies the partner and reports that partner's share of the partnership's income, deductions, credits, and other tax items.

Partners use this information when preparing their own tax returns.

Depending on the partner and the partnership's activities, additional forms or schedules may be required.

Schedule L, M-1, and M-2

Form 1065 also contains schedules that provide additional financial and tax information.

Schedule L — Balance Sheet

Schedule L generally reports the partnership's assets, liabilities, and partners' capital accounts.

Schedule M-1 — Reconciliation of Income

Schedule M-1 reconciles the partnership's book income or loss with the income or loss reported for tax purposes. Differences can occur because financial accounting and tax accounting do not always treat transactions in the same way.

Schedule M-2 — Analysis of Partners' Capital Accounts

Schedule M-2 tracks changes in the partners' capital accounts during the tax year.

Some partnerships may be required to file Schedule M-3 instead of Schedule M-1, depending on their size and other requirements.
