Form 1065

Information needed to fill out Form 1065

What is Form 1065?

IRS Form 1065, U.S. Return of Partnership Income, is the tax return partnerships use to report their annual income, deductions, gains and losses. The partnership itself does not pay income tax. Instead, Form 1065 is an informational return that shows the IRS how the business performed during the tax year.

After filing, the partnership generates a Schedule K-1 for each partner. The K-1 reports that partner's share of the partnership's income and deductions, which the partner then uses to complete their personal tax return.

Who needs to file Form 1065?

Several types of business entities are required to file Form 1065:

• Domestic partnerships. Any business with two or more partners operating as a general partnership, limited partnership or limited liability partnership must file.
• Multi-member LLCs. An LLC with two or more members is treated as a partnership by default and must file Form 1065 unless it has elected corporate tax treatment.
• Foreign partnerships with U.S. income. Foreign partnerships earning income from U.S. sources or with U.S.-based partners are generally required to file.
• Single-member LLCs do not file Form 1065. A single-member LLC is a disregarded entity, so the owner reports business income on their personal return using Schedule C.

Records and documents you need to prepare Form 1065

Having the right records organized before you start makes the filing process faster and reduces the risk of errors. Below is a breakdown of what you will need and how each item is used on the return.

Partnership identification

Every partnership needs an employer identification number (EIN) to file Form 1065. This is the nine-digit number the IRS assigns to the business, and it appears at the top of the return. If the partnership does not yet have an EIN, you can apply for one through the IRS website or by filing Form SS-4.

Income records

Form 1065 requires the partnership to report all sources of income for the tax year. Gather revenue statements, invoices, bank deposit records and 1099 forms received from clients or customers. If the partnership earns rental income, interest or capital gains, you will need supporting records for each of those categories as well.

Expense documentation

Deductible business expenses reduce the partnership's reported income. Organize receipts and records for common expenses, including:

• Rent or lease payments for office or business space
• Utilities, internet and phone costs
• Office supplies and equipment purchases
• Professional fees for accounting, legal or consulting services
• Insurance premiums
• Advertising and marketing costs
• Travel and business meal expenses

Each deduction category has a corresponding line on Form 1065, so grouping expenses by type before you start will save time.

Payroll records

If the partnership has employees, you will need wage and salary records, payroll tax filings and copies of any W-2s or 1099-NEC forms issued during the tax year. These figures are reported as deductible expenses on the return and must match what was filed with the Social Security Administration and state agencies.

Partner ownership and allocation details

Form 1065 requires specific information about each partner's role in the business. You will need to know each partner's ownership percentage, profit-and-loss sharing ratio, capital contributions made during the year and any distributions received. This information flows directly into the Schedule K-1s generated for each partner.

Guaranteed payment records

Guaranteed payments are fixed amounts paid to a partner for services or the use of capital, regardless of whether the partnership earned a profit. These payments must be reported on Form 1065 and are listed separately on each partner's Schedule K-1. Keep records of the amounts paid, the dates and the partner who received them.

Depreciation and asset records

If the partnership owns equipment, vehicles, furniture or other depreciable assets, you will need records showing each asset's purchase date, cost and the depreciation method being used. Form 4562 is used to calculate and report depreciation, and the totals carry over to Form 1065.

Prior-year tax returns

Having the previous year's Form 1065 and Schedule K-1s on hand is helpful for reference. Prior-year returns can guide you through recurring line items, help you identify carryforward deductions and ensure consistency in how partner allocations are reported from year to year.

When is Form 1065 due?

Form 1065 is due on March 15 for partnerships operating on a calendar year. If the due date falls on a weekend or federal holiday, the deadline shifts to the next business day. Partnerships using a fiscal year must file by the 15th day of the third month after their tax year ends.

Partnerships can request a six-month extension by filing Form 7004 before the original due date, which moves the deadline to September 15 for calendar-year filers. The extension gives additional time to file but does not extend the deadline for providing K-1s to partners.

Penalties for filing Form 1065 late

The IRS penalizes partnerships that file Form 1065 after the deadline without an approved extension. For the 2025 tax year, the penalty is $255 per partner for each month or partial month the return is late, up to a maximum of 12 months.

For a partnership with four partners, a return filed three months late would result in a $3,060 penalty. Filing Form 7004 for an extension before the deadline is the simplest way to avoid these charges if the partnership needs more time.
