Multi-Member LLC: Do You Need a CPA for Form 1065 and K-1s?

Do we need a CPA, or can we file our multi-member LLC's Form 1065 ourselves?

No rule requires a CPA to prepare a partnership return. A multi-member LLC taxed as a partnership files Form 1065, and one member must sign it. Anyone paid to prepare the return generally must also sign as preparer with a preparer tax identification number (PTIN); if an owner or employee completes it, the paid-preparer space stays blank (Form 1065 instructions).

The real question is whether the return can be right without professional judgment. Each row below adds some:

Several of these points are hard to change once the due date has passed: the tax code limits changes to K-1 information after that date, with listed exceptions (section 6031(b)). Once the filing period, including any valid extension, has closed, a return under the centralized audit rules generally needs an administrative adjustment request, not an amended return (Form 1065 instructions); before then, a superseding Form 1065 with matching K-1s can replace it (Revenue Procedure 2019-32). See correcting a filed business return.

Form 1065 is due March 15 for a calendar-year LLC. Two cases are most likely to need a professional: a return that is already late, and owners who put in and took out unequal amounts so that nobody can say what each K-1 should show (see the section on when a CPA is worth paying for). Before deciding, pull together the operating agreement, a dated list of what each owner put in and took out, and the year's bank statements; the full list is further down.

Does a multi-member LLC file Form 1065 even if it made no profit?

Generally, yes. A domestic LLC with two or more members is a partnership for federal tax unless it elects corporate tax treatment (Form 8832, or Form 2553 for S corporation status), and a partnership must file Form 1065 unless it neither receives income nor incurs any expense treated as a deduction or credit (IRS: LLC classification; Form 2553 instructions; Form 1065 instructions). Spouses who are the only members of an LLC in a community property state may be able to treat it as a partnership or as a disregarded entity (Revenue Procedure 2002-69); see spouse and family LLCs.

A loss does not remove the duty: a loss year has expenses to report, and the loss passes to the owners on their K-1s (IRS: Partnerships). State returns and annual fees can apply even when no federal return is due; see which returns your business files.

When is Form 1065 due, and what does a late return cost?

A calendar-year LLC's Form 1065 is due March 15. A return that is late or leaves out required information costs the LLC $260 for each partner for each month or part of a month, up to 12 months; the IRS assesses it against the partnership (Form 1065 instructions; section 6698(c)). The dollar rate is the indexed amount for a return required to be filed in 2027 (Revenue Procedure 2025-32).

A return that is already late is charged at the rate for its own due date. The Form 1065 instructions show $255 for a return due the year before 2027, and the IRS penalty page lists earlier years.

The penalty does not apply if the partnership shows the failure was due to reasonable cause. Do not attach an explanation to the return; the IRS asks for one after it sends a notice (Form 1065 instructions). Small partnerships that meet set conditions are presumed to have reasonable cause (IRS: failure to file penalty), and first-time or other administrative relief may apply (IRS: administrative penalty relief); see late partnership return penalty relief and late filing and payment penalties.

What books does a multi-member LLC need for Form 1065?

A multi-member LLC needs books that show the year's income and expenses by category, what each owner put in and took out, and, unless a small-partnership exception applies, a year-end balance sheet that agrees with the books (Form 1065 instructions).

An LLC can skip Schedules L, M-1 and M-2, item F (total assets) on page 1 and K-1 item L when it passes the small-partnership test, question 4 on Schedule B. That needs total receipts under $250,000, total assets under $1,000,000, K-1s filed with the return and furnished on time, and no Schedule M-3 (Form 1065). Skipping the schedules does not remove the need for a record of what each owner put in and took out: each owner keeps their own record of tax basis, and the K-1 capital account cannot be used to figure it (K-1 instructions).

For setting up the accounts, see setting up books for a new LLC.

How do the K-1s split profit when owners put in and take out different amounts?

Each owner's profit share on the K-1 follows the partnership agreement, not the amount the owner put in or took out. Contributions and draws change the owner's capital account instead (section 704(a)).

The agreement can be written or oral. Owners can change it for a tax year up to the return's due date, not counting extensions, and local law fills any gap the agreement leaves (Publication 541; section 761(c)). If the agreement says nothing about an item, or an allocation does not meet the tax rules for allocations, each owner's share follows their interest in the partnership, judged on all the facts (section 704(b)).

Each owner pays tax on their K-1 share whether or not the LLC paid it out (Form 1065 instructions). K-1 item J shows each owner's share of profit, loss and capital at the start and end of the year. For a partnership that never tracked these, see rebuilding partnership capital accounts.

What are guaranteed payments, and how do they differ from draws?

A guaranteed payment is a payment to an owner that is set without regard to the LLC's income, for work or for use of capital. A draw is a distribution of money the owner is entitled to as an owner. The two are reported differently (Publication 541).

The IRS says partners are not employees and should not be issued a Form W-2. For the books side, see guaranteed payments versus partner draws; for how each is taxed to the owner, including self-employment tax, see how partnerships are taxed.

What is a capital account, and what does the K-1 ask for?

A capital account is each owner's running stake in the LLC: money and property put in, plus the owner's share of income, minus losses and money or property taken out. K-1 item L asks for it by owner, figured under the tax-basis method, unless the small-partnership test on Schedule B (question 4) applies (Form 1065 instructions).

Item L runs from the beginning capital account (last year's ending balance) through capital contributed, the owner's share of net income or loss, other increases or decreases, and withdrawals and distributions, to the ending capital account, which can be negative. A contribution counts as cash plus the property's adjusted tax basis, not its market value, less any debt the LLC assumes or the property is subject to (Form 1065 instructions).

The ending capital account is not the owner's tax basis, which also includes the owner's share of LLC debt. The ending balances across all K-1s should add up to the ending balance on Schedule M-2. For keeping the account in the books year to year, see partner capital accounts.

Where does filing Form 1065 ourselves go wrong?

A self-prepared return can break wherever the tax rules ask for something the books never captured. These are the points the IRS materials make specific:

Where do we start with the books and the first return?

Start with two things: the operating agreement, which sets each owner's share, and a dated list of what each owner put in and took out. Then add the rest of this list.

1. The operating agreement and every amendment, or a written note of the profit, loss and capital split the owners agreed to.
2. The EIN confirmation letter, the date each owner joined (and left), and each owner's name, address and taxpayer identification number: Social Security number or individual taxpayer identification number (ITIN) for a person, EIN for a company. For an owner that is a disregarded entity, the K-1 uses its owner's number, so gather both.
3. Any Form 8832 or Form 2553 election, its effective date and IRS acceptance, and any other IRS or state letters.
4. Bank, card and loan statements for every month of the year, including any account where business and personal money mixed.
5. A list of what each owner put in and took out, by date. For contributed property: what the owner paid, when, any depreciation taken, and the market value on the day it went in.
6. The prior return, K-1s and year-end balance sheet, or confirmation that this is the first year.
7. Payroll and contractor payment records, if the LLC has them.
8. Two decisions: the accounting method (cash or accrual) and who acts as partnership representative.

When is a CPA worth paying for a multi-member LLC return?

Filing yourself is more realistic when the LLC has few owners, one year to file, cash-only contributions and books that match the bank. Professional help is more likely to matter when a mistake would be costly or hard to undo, as in the right-hand column.

The cost of an error is easy to size. The late-return penalty is the per-partner rate times the number of owners times the months late, and a late or wrong K-1 carries its own penalty per owner. The work grows with the same factors: the number of owners (each gets a K-1), the number of years involved, whether capital accounts exist, whether owners contributed property or joined or left, and whether the books reconcile to the bank. A preparer's fee usually follows the work.

For the choice between keeping the day-to-day books yourself and hiring a bookkeeper, see doing your own books or hiring a bookkeeper.

Example

These examples are illustrative and use US dollars.

Equal owners, unequal draws

Two friends own a design LLC 50/50 under a written agreement. Revenue is US$120,000 and profit is US$30,000. Each put in US$5,000 at the start. One drew US$14,000 and the other US$6,000. Assume no guaranteed payments and no debt.

Each K-1 shows US$15,000 of profit, because the agreement splits profit equally. The draws change the capital accounts, not the profit:

The US$8,000 gap is not a tax item, but it has to be recorded. If this LLC passes the small-partnership test it can skip item L, but the owners still need the per-owner record. What they do about the gap belongs in their agreement.

A late return with three owners

A three-member LLC with no extension files its Form 1065 during the fifth month after the due date. At the per-partner rate on this page, the penalty is US$260 x 3 partners x 5 months, which is US$3,900, before any relief. The count is everyone who was a partner at any time in the year: a fourth owner who left in January would make it US$5,200. Small-partnership or first-time relief may remove the penalty (see above). Penalties for late or wrong K-1s are separate.

Cash from one owner, a truck from another

One member puts in US$40,000 cash. Another puts in a truck bought for US$25,000 and used personally, now worth US$40,000, with no loan on it. If the agreement credits each owner US$40,000, the book capital accounts are equal. The tax-basis accounts on the K-1 are not:

The LLC's basis in the truck is US$25,000. If the LLC later sells it for US$40,000, the US$15,000 of built-in gain is generally allocated to the member who contributed the truck. If item L is required (the small-partnership test is not met), a return that uses US$40,000 for both owners gets item L wrong for the truck owner.

Different for you?

• Your first Form 1065 is due or already late, and the owners put in and took out unequal money, so nobody can say what each K-1 should show: the entity treatment, the capital accounts, the books the return needs and the penalty exposure all affect one another. Start with late partnership return penalty relief and rebuilding partnership capital accounts, then get corporate tax help.
• Several years of returns were never filed: see catching up on unfiled business returns and get corporate tax help.
• The books are behind or were never kept: see catching up on overdue books and get bookkeeping help.
• Only spouses own the LLC: see spouse and family LLCs for whether the business files Form 1065 or Schedule C.
• An owner lives outside the US: the LLC may have withholding and extra filings; see foreign partners and withholding.
• An owner is leaving or being bought out: if only one owner remains, the partnership ends and a final Form 1065 is due the 15th day of the 3rd month after the month the partnership ends (Revenue Ruling 99-6); see buying out a partner.
• K-1s already went out and are wrong: see correcting a filed business return.
• The LLC elected corporate or S corporation treatment: a different return applies; see how LLCs are taxed.
