What Form 1065 is for
Form 1065 is an information return. Your partnership uses it to report the income, gains, losses, deductions, and credits from running the business. The partnership usually pays no tax on that income. It passes the profit or loss through to the partners, and each partner reports their share on their own tax or information return.
You file it if you run a domestic partnership, including an LLC with at least two members that is treated as a partnership. Two spouses who jointly own and operate an unincorporated business are partners and file Form 1065, unless they elect qualified joint venture treatment. Foreign partnerships with U.S. income file too, with some exceptions. You attach a Schedule K-1 for every partner.
Who has to file Form 1065?
Every domestic partnership files Form 1065, unless it took in no income and had no expenditures treated as deductions or credits. An LLC classified as a partnership has the same filing duty. A domestic LLC with at least two members that does not file Form 8832 is classified as a partnership by default. A religious or apostolic organization exempt under section 501(d) files Form 1065 to report its taxable income, which goes to its members as a dividend whether it is handed out or not.
A foreign partnership generally files if it has income effectively connected with a U.S. trade or business, or income from U.S. sources. Two narrow exceptions in the instructions can excuse a foreign partnership with U.S. source income. A partnership that is, or has a branch that is, a qualified derivatives dealer files Form 1065 even when it would not have to otherwise.
- A married couple electing qualified joint venture status reports on their joint return instead
- A group electing out of subchapter K under section 761(a) files only for the year of the election
- Real estate mortgage investment conduits file Form 1066
- Publicly traded partnerships treated as corporations under section 7704 file Form 1120
- A partnership seeking certification as a qualified opportunity fund files Form 1065 with Form 8996 even with no income or expenses
When is Form 1065 due?
A domestic partnership files by the 15th day of the 3rd month after the end of its tax year, as shown at the top of the form. For calendar year partnerships, that is March 15. If the due date falls on a Saturday, Sunday, or legal holiday, a return filed on the next day that is none of those counts as timely. So calendar year partnerships can file for the 2025 year by March 16, 2026.
If you need more time, file Form 7004 by the regular due date of the partnership return. Form 7004 can be filed electronically. The 2025 Form 1065 covers calendar year 2025 and fiscal years that begin in 2025 and end in 2026.
Where do you send Form 1065?
The mailing address depends on where your partnership's principal business, office, or agency sits, and on your total assets at the end of the year. Partnerships in the eastern and midwestern states listed in the instructions, with total assets less than $10 million and no Schedule M-3, mail to the Internal Revenue Service Center, Kansas City, MO 64999-0011. The rest of those partnerships go to Ogden, UT 84201-0011.
Partnerships in the western and southern states listed in the instructions mail to Ogden, UT 84201-0011 for any amount of assets. If your principal office is in a foreign country or a U.S. territory, send the return to Internal Revenue Service, P.O. Box 409101, Ogden, UT 84409. Any return filed with Schedule M-3 goes to Ogden.
Do you have to file Form 1065 electronically?
You must file Form 1065 and its related forms and schedules electronically if your partnership files 10 or more returns of any type during the tax year. That count takes in information returns, income tax returns, employment tax returns, and excise tax returns. Partnerships with more than 100 partners must also file Form 1065, the Schedules K-1, and related forms electronically.
Two ways out exist. The IRS may waive the rule if you show that filing electronically would cause a hardship, and you request that waiver in writing through the Ogden Submission Processing Center. If the technology conflicts with the religious beliefs of the partners, you may file on paper and write Religious Exemption at the top of page 1. Bankruptcy returns and returns with pre-computed penalty and interest are also outside the requirement.
How do you fill out Form 1065?
Page 1 holds trade or business income and expenses only. Keep rental activity income and portfolio income off lines 1a through 23 and report them on Schedule K instead, with rental real estate going on Form 8825. Schedule B asks about entity type, ownership, foreign accounts, elections, and digital assets. Schedule K totals every partner's share of income, deductions, and credits, and you attach one Schedule K-1 for each partner. File all six pages, and complete every applicable entry space rather than writing See attached.
- Answer Yes to Schedule B question 4 and you can skip Schedules L, M-1, and M-2, item F on page 1, and item L on Schedule K-1
- Total receipts for the year less than $250,000
- Total assets at the end of the year less than $1 million
- Schedules K-1 filed with the return and given to partners by the due date, including extensions
- No Schedule M-3 filed or required
What changed on the 2025 Form 1065?
Payments to and from the federal government are moving away from paper checks and money orders. If you have a balance due on line 31, go to IRS.gov/Payments. New direct deposit fields appear on lines 32b, 32c, and 32d, so an overpayment on line 32a can come back to your bank account.
Section 174A now allows domestic research or experimental costs paid or incurred in tax years beginning after 2024 as a current-year deduction, or you can elect to charge them to a capital account and amortize over at least 60 months. Schedule B question 19 was widened to cover payments received that are allocable to foreign partners.
- Line 13, code X covers qualified sound recording production costs for productions that commence in a tax year ending after July 4, 2025, and before 2026
- Line 19 has more distribution codes, with instructions on where each category goes
- Line 20, code AR will require an EIN after 2025 for IRA partners receiving unrelated business taxable income
- Line 20, code AZ reports reimbursement of preformation expenditures
- Line 20, code ZZ covers section 1062, under which gain on qualified farmland sold to qualified farmers can be paid in four equal installments
