Understanding Form 1065: Partnership Income Tax Return

Updated: Feb 27

What is Form 1065?


Form 1065 is an information return that partnerships file to report their income, gains, losses, deductions, credits, and other items. Partnerships do not pay federal income tax. Instead, these items are "passed through" to partners, who report them on their personal tax returns.


Who Must File?


  • General Partnerships

  • Limited Partnerships

  • Limited Liability Partnerships


Due Date


The due date for filing Form 1065 is March 15. If this date falls on a weekend or holiday, the deadline is the next business day.


Extensions


To request an automatic 6-month extension, file Form 7004. For partnerships with a calendar year ending December 31, the deadline for filing with an extension is September 15 (or the next business day if it falls on a weekend or holiday).


Form 1065 Structure


Form 1065 consists of several key sections:


  • Page 1: Income, Deductions, and Tax Payments

  • Schedule B: Other Information

  • Schedule K: Partners' Distributive Share Items

  • Schedule L: Balance Sheet

  • Schedule M-1: Reconciliation of Income

  • Schedule M-2: Analysis of Partners' Capital Accounts


Page 1: Income, Deductions, and Tax Information


This section includes header information such as the partnership name, address, EIN, date established, and accounting method.


Schedule B: Other Information


This schedule contains yes/no questions about:


  • Type of entity

  • Accounting methods

  • Foreign accounts or activities

  • Ownership and partners

  • Payments to foreign persons or related party transactions


Schedule K: Partners' Distributive Share Items


This schedule summarizes total partnership items allocated to partners, including:


  • Ordinary business income (loss)

  • Net rental real estate income/loss

  • Other rental income/loss

  • Interest, dividends, capital gains/losses

  • Deductions: Section 179, charitable contributions, other deductions

  • Foreign transactions

  • Alternative Minimum Tax (AMT) items

  • Credits and other tax items


Schedule L: Balance Sheet


This section shows assets, liabilities, and partners' capital accounts at the beginning and end of the year. It must reconcile with the partnership's books.


Schedule M-1: Reconciliation of Income


This schedule reconciles book income to tax income. It includes adjustments for permanent and temporary differences between accounting records and taxable income.


Schedule M-2: Analysis of Partners' Capital Accounts


This schedule tracks changes in partners' capital during the year, including:


  • Beginning capital balance

  • Contributions

  • Net income/loss

  • Distributions

  • Ending capital balance


Schedule K-1 (Form 1065)


This form is issued to each partner to report their share of income, deductions, credits, and other items. Partners use K-1 to report these items on their personal tax returns (Form 1040).


Partnership Basis


What is Partnership Basis?


The partnership basis is the tax value a partner has in their investment in a partnership. It determines:


  • How much loss a partner can deduct on their personal tax return.

  • How much gain or loss is recognized when a partner sells or disposes of their interest.

  • How distributions (cash or property) are taxed.


Initial Basis


The initial basis includes:


  • Initial money and property contributed by a partner to the partnership.

  • If you invest cash, your basis increases by the cash amount.

  • If you contribute property, your basis is generally the adjusted tax basis of the property.


Adjustments to Basis


Transactions that occur after the initial investment lead to annual changes in the partner's basis. These include:


Increases


  • Share of partnership income (ordinary business income, rental income, interest, dividends, capital gains).

  • Additional capital contributions by the partner.


Decreases


  • Share of partnership losses (limited to basis).

  • Distributions of cash or property from the partnership.

  • Share of deductions (i.e., Section 179).


Uses of Basis in Partnership


  • Loss Limitation: A partner can deduct losses only up to his/her basis in the partnership.

  • Distribution Taxability: Cash distributions generally reduce basis and are not taxable if they don't exceed basis. Distributions in excess of basis are taxable as capital gains.

  • Sale or Transfer of Partnership Interest: Gain or loss is calculated as selling price minus adjusted basis.
