Your partnership reports, and each partner gets a K-1.
A partnership, including a multi-member LLC, does not pay federal income tax itself. It files Form 1065 to report its income, then hands each partner a Schedule K-1 for their share, which they report on their own return. We prepare the return, generate the K-1s, and file on time so no partner is left waiting.
The partnership reports; the partners pay.
Form 1065 is the annual return of a partnership, which for tax purposes includes most multi-member LLCs. Like an S-corporation, a partnership is a pass-through entity: it does not pay federal income tax itself. The return reports the partnership's income, deductions, and credits, and then allocates each partner their share on a Schedule K-1. Partners report those amounts on their own returns and pay the tax there. The return is filed every year the partnership operates, and getting each partner's allocation right is the core of the work.
So what does the finished filing produce? Here it is.
One return, and a K-1 for every partner.
Form 1065 produces two things that matter. The return reports the partnership's activity to the IRS. Alongside it, each partner receives a Schedule K-1 showing their share of income, deductions, and credits, which they need to file their own return. Because partnership allocations can be more involved than a simple ownership split, getting the K-1s right is the heart of the filing. We prepare the return, generate accurate K-1s, e-file, and store everything together.
Most multi-owner businesses file this, but not all. Here is who does.
Partnerships and multi-member LLCs file 1065.
Form 1065 is the default return for a business with two or more owners that has not elected corporate taxation. Here is the line.
File Form 1065 if
- You are a general or limited partnership.
- You are a multi-member LLC that has not elected corporate taxation.
- The business has two or more owners sharing profit and loss.
- The partnership operated during the year.
File a different return if
- You are a single-member LLC. You are disregarded and report on the owner's return.
- Your LLC elected S-corporation taxation. That is Form 1120-S.
- Your LLC elected C-corporation taxation. That is Form 1120.
- You are a corporation by default. You file a corporate return, not 1065.
A point worth knowing: a multi-member LLC is treated as a partnership for federal tax by default, so it files Form 1065 unless it has elected to be taxed as a corporation. Adding a second owner to what was a single-member LLC changes the filing from the owner's personal return to a partnership return, a shift that surprises owners who did not realize the tax treatment changed with the ownership. We confirm your classification so you file the right return for how the business is actually owned.
Right return for you? Here are the dates and penalties.
March 15, and the penalty is per partner.
These figures were verified against current IRS guidance. The per-partner penalty adjusts each year.

From the books to the return and the K-1s.
The return and each partner's K-1 come from the same records and the partnership agreement. Here is the sequence.
Confirm partners and allocations
We capture each partner and their share of profit and loss, including any special allocations in the partnership agreement, which drive the K-1s.
We prepare the return and K-1s
We complete Form 1065 from your financials and generate a Schedule K-1 for each partner with their allocated share.
We e-file and deliver the K-1s
We e-file the return and get each partner their K-1 by the deadline, so their personal returns are not held up.
We set next year's date
The next deadline goes on your calendar, and we keep the partnership's filings consistent from year to year.
The K-1s feed several personal returns at once. Here is what we bring to it.
Accurate allocations, delivered on time.
A partnership return is only as good as its K-1s, because each one feeds a partner's personal filing. The value here is correct allocations, filed by the March deadline, with every partner's K-1 in hand.
Every partner accounted for
- We reflect the ownership shares and any special allocations.
- We produce a complete, accurate K-1 for each partner.
- We deliver them by the deadline so no one's return waits.
The March deadline held
- Need more time? We file the 7004 extension first.
- The deadline sits on your compliance calendar.
- The return and K-1s live together with your other filings.

The partnership return sits in a wider federal picture. Here is the road.
The partnership return connects to the whole.
The 1065 follows your federal ID and your extension, feeds each partner's return, and depends on clean books. They live on one platform, so nothing is filed in isolation.
Number it, extend it, file it, and keep the books behind it, all inside File.Business. One platform holds the partnership return and everything that feeds it.
The questions partners ask about Form 1065.
When is Form 1065 due?
For a calendar-year partnership, Form 1065 is due March 15, the 15th day of the third month after the tax year ends, the same early date as an S-corporation. This is a month before the deadline for C-corporations and individuals, which catches partnerships that assume an April date. Filing Form 7004 by March 15 gives an automatic six-month extension to September 15. We confirm your exact dates based on your fiscal year.
Does a partnership pay income tax?
No. A partnership is a pass-through entity and does not pay federal income tax itself. It files Form 1065 as an information return, then allocates income, deductions, and credits to the partners on Schedule K-1. Each partner reports their share on their own return and pays the tax there. This single layer of tax at the partner level is a defining feature of the partnership structure, and it is why multi-member LLCs are taxed this way by default.
Does my multi-member LLC file Form 1065?
By default, yes. A multi-member LLC is treated as a partnership for federal tax unless it has elected to be taxed as a corporation, so it files Form 1065 and issues K-1s to its members. This surprises some owners, especially when a single-member LLC adds a second owner and its tax filing shifts from the owner's personal return to a partnership return. We confirm your classification so the right return is filed for how the LLC is owned.
What is the penalty for filing late?
The partnership late-filing penalty is charged per partner, not as a percentage of tax. For a return filed late without a valid extension, it is 255 dollars per partner, per month, for up to twelve months, for the 2025 tax year, and the amount is adjusted annually. Because it applies even when the partnership owes no tax, a late 1065 with several partners adds up fast. Filing on time, or extending with Form 7004, avoids it entirely.
What is a Schedule K-1 and why does timing matter?
A Schedule K-1 reports each partner's share of the partnership's income, deductions, and credits. Partners cannot complete their personal returns without it, so the K-1s must go out by the filing deadline. A late or incorrect K-1 delays every affected partner's return, which is why we treat producing accurate K-1s on time as central to the filing rather than a follow-up task. Correct allocations up front prevent amended returns later.
Do partners need to make their own tax payments?
Generally yes. Because the partnership does not withhold tax on a partner's share of income, partners often need to make quarterly estimated tax payments on their own to cover the tax on their allocated income. The partnership return and K-1 report the income, but paying the tax is the partner's responsibility. We can flag this so partners understand their estimated-payment obligations rather than facing an unexpected balance when they file their personal returns.
Can Form 1065 be e-filed?
Yes, and many partnerships are now required to file electronically rather than on paper. E-filing returns an acknowledgment of receipt, useful as proof of timely filing, and lets us deliver the K-1s alongside the return efficiently. We e-file wherever available, which is the standard path for partnership returns, and store the acknowledgment and K-1s with your records. Where a specific situation requires a different method, we handle it correctly.
