Every multi-member LLC files Form 1065 each year, because the IRS treats it as a partnership by default. The return is due March 15, it reports no tax itself, and it issues a Schedule K-1 to each member. The LLC files it under the EIN the IRS assigned on Form SS-4.
Form 1065 is the return that surprises new LLC owners, because nothing about forming the company announces it. The obligation arrives with the second member, applies whether or not the LLC earned anything, and carries a penalty calculated per member. This page covers who files, when, and how the return connects back to the EIN on Form SS-4. Whether Form 1065 applies to you at all is decided upstream by how the IRS treats your entity, so if you are unsure which default you landed in, start with llc tax classification and come back. Segregated structures complicate the return count, because whether each cell files its own 1065 depends on whether it holds its own number, which is the question ein for series llc takes on.
Which LLCs file Form 1065?
Every LLC with 2 or more members files Form 1065. The IRS classifies a multi-member LLC as a partnership by default, and partnerships file Form 1065 every year the LLC exists.
Member count decides the return. A single-member LLC is a disregarded entity and reports on Schedule C inside the owner's Form 1040. Add a second member and the LLC becomes a partnership for federal tax purposes, and Form 1065 replaces Schedule C from that tax year forward.
The default applies whether or not the members signed a partnership agreement, and whether or not the LLC distributed any money. An LLC with 2 members and $0 of revenue still files. The IRS treats the filing obligation as attached to the classification, not to the activity.
An LLC that elected corporate treatment files something else. Form 8832 moves the LLC to Form 1120, and Form 2553 moves it to Form 1120-S. Read how those three fields interact on the LLC tax classification page before assuming which return applies.
One exception narrows the rule. An LLC owned solely by a married couple in a community property state elects qualified joint venture treatment and files 2 Schedule Cs instead of Form 1065. That election is open in 9 community property states, and every other 2-member LLC files the partnership return.
When is Form 1065 due for an LLC?
Form 1065 is due March 15 for an LLC on the calendar year, one month before the personal deadline. Form 7004 extends the filing date by 6 months, to September 15.
The March date exists for a reason. Each member needs a Schedule K-1 from the LLC before filing a personal return in April, so the partnership deadline sits a month earlier to make that possible.
A fiscal-year LLC files on the 15th day of the third month after its year closes. The closing month came from line 12 of Form SS-4 when the LLC applied for its EIN, which is why that field matters years after the application.
Form 7004 extends the return, not the members' personal deadlines. A member still files a personal return in April, using the K-1 the LLC issued or an estimate until the extended return arrives.
The extension is automatic and carries no approval step. Form 7004 filed by March 15 moves the deadline to September 15 without an IRS response, and an LLC that files it 1 day late gets no extension at all.
The first return has its own timing. An LLC formed mid-year files for a short first tax year, running from the formation date to December 31, and the March 15 deadline follows the close of that short year rather than a full 12 months of activity.
What does Form 1065 report?
Form 1065 reports the LLC's income, deductions, gains, and losses, then allocates each member's share on a Schedule K-1. The LLC pays no federal income tax on the return itself.
A partnership is a pass-through entity. The LLC calculates the result, then passes each member's share to that member's personal return through the K-1. Tax is paid by the members, at their own rates, on their own returns.
The K-1 carries each member's distributive share of ordinary business income, rental income, interest, dividends, capital gains, deductions, and credits. It also reports the member's capital account and ownership percentage at the start and end of the year.
A member owes tax on the allocated share whether or not the LLC distributed cash. An LLC that reinvested every dollar still allocates income, and the members still report it. That gap between allocation and distribution surprises first-year partnerships more than any other rule on the return.
The return runs to 5 pages before schedules. Page 1 carries ordinary business income, pages 2 and 3 carry Schedule B, page 4 carries Schedule K, and page 5 carries Schedules L, M-1 and M-2 for the balance sheet and capital reconciliation. Smaller LLCs skip Schedules L, M-1 and M-2 when they meet the receipts and asset thresholds in the instructions.
Which EIN does an LLC file Form 1065 under?
The LLC files Form 1065 under the 9-digit EIN the IRS assigned through Form SS-4. A partnership return requires an EIN, so the LLC obtains one before the first filing deadline.
Line 8b of Form SS-4 sets this in motion. That field records the number of LLC members, and 2 or more members produces partnership classification, which produces the Form 1065 obligation for every year that follows.
The name on the return matches the name the IRS holds against the EIN. The IRS pairs an EIN with the exact legal name from line 1 of Form SS-4, and a return filed under a name that reads differently fails the match.
An LLC that changes from single-member to multi-member keeps its EIN and changes its filing. The number stays with the entity, and the return changes from Schedule C to Form 1065 for the year the second member joined.
That last point has one important exception. A sole proprietor who obtained an EIN personally and then formed an LLC holds the wrong number for the partnership. The EIN belongs to the proprietorship, and the new LLC applies for its own on a fresh Form SS-4.
Every Schedule K-1 carries the same EIN as the return. The member's own identifying number goes in Part II of the K-1, and the LLC's EIN goes in Part I, so a 3-member LLC issues 3 K-1s sharing 1 entity number.
How does an LLC file Form 1065?
The LLC closes its books, completes Form 1065 and Schedule K, allocates each member's share according to the operating agreement, issues a Schedule K-1 to every member, then files the return by March 15.
Allocation follows the operating agreement rather than a default split. Two members holding 60 and 40 percent receive 60 and 40 percent of the allocated income, and an agreement that specifies a different allocation controls instead. Members who never wrote the percentages down argue about them in the first filing season.
Schedule K aggregates the LLC's results, and each Schedule K-1 carries one member's slice of that total. The K-1s reconcile back to Schedule K exactly, and a discrepancy between them is one of the first things an examiner checks.
Delivery timing matters as much as filing. Each member needs the K-1 to complete a personal return by April 15, so an LLC that files at the March deadline without sending K-1s leaves every member unable to file on time.
A partnership with more than 100 partners files electronically. Smaller LLCs choose between e-file and paper, and e-file produces a dated acknowledgement that paper filing does not.
Every Form 1065 needs a signature from a partner or member manager, and a paid preparer adds a PTIN in the preparer block. An unsigned return is treated as unfiled, and the late-filing penalty runs from the original deadline rather than the date it arrived.
What records does an LLC need for Form 1065?
The LLC needs a full year of books, the operating agreement with ownership percentages, each member's capital account, records of contributions and distributions, and the EIN the IRS assigned on Form SS-4.
Capital accounts track what each member put in, took out, and was allocated. The K-1 reports the account at the start and end of the year, and reconstructing 12 months of untracked movements in March is the most avoidable cost in a first partnership return.
Contributions and distributions are separate from income. A member who contributed $10,000 and later withdrew $4,000 records both movements, and neither figure is the same as the income allocated on the K-1.
The operating agreement supplies the allocation percentages the return depends on. An LLC without one falls back to state default rules, which rarely match what the members believed they agreed to.
Keep the CP-575 with the tax records. The return is filed under the EIN on that letter, and the legal name printed there is the name the IRS matches the return against.
Hold the records for 3 years after the filing date at minimum, and 7 years where the return involves bad debts or worthless securities. Records supporting a member's capital account outlive that window, because the account carries forward from year to year until the member exits.
What happens when an LLC files Form 1065 late?
The IRS charges a monthly late-filing penalty for each partner under Internal Revenue Code section 6698. A 2-member LLC accrues the penalty twice each month, and the charge applies to a return reporting $0 of income.
The penalty is calculated per partner, per month or part of a month, for up to 12 months. Member count multiplies it, so a 4-member LLC accrues 4 times the monthly figure a single partner would trigger.
A return showing no income carries the same exposure as a profitable one, because the penalty attaches to the failure to file rather than to a tax due. That structure catches dormant LLCs whose owners assumed no activity meant no return.
The IRS publishes the current per-partner monthly figure in the Form 1065 instructions, and indexes it. Check the instructions for the filing year rather than relying on a figure quoted anywhere else, including here.
Section 6698 waives the penalty where the LLC shows reasonable cause. A first-time filer that missed the deadline and filed promptly has a stronger position than one that ignored 3 notices, and the request goes in writing in response to the penalty notice.
A late Schedule K-1 carries its own penalty, separate from the return. Failing to furnish a K-1 to a member is charged per statement under section 6722, so a late 4-member return exposes the LLC on both counts at once.
How does Form 1065 apply to a foreign-owned LLC?
A multi-member LLC with foreign members files Form 1065 like any other partnership. A single-member LLC with a foreign owner files Form 5472 with a pro-forma Form 1120 instead, and never files Form 1065.
Member count decides the form here too. Two foreign members produce a partnership and a Form 1065. One foreign member produces a disregarded entity and the Form 5472 obligation, which carries a $25,000 annual penalty under Internal Revenue Code section 6038A for a missed filing.
A partnership with foreign partners also carries withholding duties on effectively connected income. Those obligations sit on top of Form 1065 rather than replacing it, and they are the reason foreign-member partnerships engage a US CPA earlier than domestic ones.
Both paths begin at the same place: an EIN issued on Form SS-4, with the member count entered correctly on line 8b. A wrong number in that field routes the LLC to the wrong annual return for the life of the company.
Neither path requires the owner to hold an SSN. Line 7b of Form SS-4 accepts the entry Foreign, and the application goes by fax to 855-215-1627 with a 4 to 7 business day turnaround. The EIN issues first, and the choice between Form 1065 and Form 5472 follows from the member count.
Which return does your LLC file?
Member count and elections decide the return. A single member files Schedule C, 2 or more members file Form 1065, and an election moves the LLC to Form 1120 or Form 1120-S.
| LLC structure | Federal classification | Annual return | Deadline |
|---|---|---|---|
| Single-member, US owner | Disregarded entity | Schedule C with Form 1040 | April 15 |
| Single-member, foreign owner | Disregarded entity | Form 5472 + pro-forma 1120 | April 15 |
| 2 or more members | Partnership | Form 1065 + Schedule K-1 | March 15 |
| Elected corporation, Form 8832 | Corporation | Form 1120 | April 15 |
| Elected S corporation, Form 2553 | S corporation | Form 1120-S | March 15 |

What else do LLC owners ask about Form 1065?
+Does a single-member LLC file Form 1065?
No. A single-member LLC is a disregarded entity and reports on Schedule C inside the owner's Form 1040. Form 1065 applies once the LLC has 2 or more members. A foreign-owned single-member LLC files Form 5472 with a pro-forma Form 1120 instead.
+When is Form 1065 due for an LLC?
March 15 for an LLC on the calendar year, one month before the April personal deadline. Form 7004 extends the return by 6 months, to September 15. A fiscal-year LLC files on the 15th day of the third month after its year ends.
+Does an LLC pay tax on Form 1065?
No. Form 1065 is an information return, and the LLC pays no federal income tax on it. The return allocates each member's share on a Schedule K-1, and each member reports that share on a personal return and pays tax at personal rates.
+Does an LLC need an EIN to file Form 1065?
Yes. A partnership return requires the 9-digit EIN the IRS assigned through Form SS-4, and the IRS matches the return against the exact legal name attached to that EIN. An LLC obtains the EIN before the first March 15 deadline.
+Does an LLC with no income still file Form 1065?
Yes. The obligation attaches to partnership classification, not to activity, so a 2-member LLC with $0 of revenue still files by March 15 each year. The late-filing penalty under Internal Revenue Code section 6698 applies per partner even when the return reports nothing, at $220 per partner per month for up to 12 months as of 2026.
+What is a Schedule K-1 for an LLC?
Schedule K-1 reports 1 member's distributive share of the LLC's income, deductions, and credits, plus the capital account and ownership percentage. The LLC issues 1 K-1 per member, and each member attaches the figures to a personal Form 1040 return by April 15. Missing 1 K-1 blocks each member from filing on time.
+Does a member owe tax on money the LLC did not distribute?
Yes. A member reports the share allocated on the K-1 whether or not the LLC distributed cash. An LLC that reinvested all of its 2026 profit still allocates that income, and the members still report it on personal returns for that year.
+What happens when a single-member LLC adds a second member?
The LLC becomes a partnership for federal tax purposes and files Form 1065 from that tax year, due March 15 the following year. It keeps the same 9-digit EIN, because the number stays with the entity. The return changes from Schedule C on Form 1040 to Form 1065 with 1 Schedule K-1 per member.
+Can an LLC avoid Form 1065 by electing corporate status?
Yes. Form 8832 moves the LLC to Form 1120 and Form 2553 moves it to Form 1120-S, and neither files Form 1065. Form 2553 is due within 2 months and 15 days of the start of the tax year the election takes effect.
+Do foreign members change the Form 1065 requirement?
No. A multi-member LLC with foreign members files Form 1065 like any partnership, with added withholding duties on effectively connected income. A single-member LLC with a foreign owner files Form 5472 instead, which carries a $25,000 annual penalty if missed.

Does your LLC have an EIN before it files Form 1065?
Form 1065 is filed under the EIN the IRS assigned on Form SS-4, and line 8b of that form is what put the LLC in the partnership column. We review your Articles, set lines 8a, 8b, and 9a to your actual structure, and file Form SS-4 for $97, faxed within 7 business days, or that fee is refunded. The $127 Fast tier is filed within 24 hours with the IRS call included. If the partnership return is already on your calendar, start with an EIN for your LLC, filed right the first time.
