To create a multi-member LLC, you pick a compliant name, appoint a registered agent, file Articles of Organization with your state, sign an operating agreement among the members, get an EIN from the IRS, and set up a dedicated business bank account. State filing fees run roughly $35 to $500, and the paperwork itself can clear in a few business days where online filing is available. The harder work is what follows: dividing ownership, choosing a tax treatment, and writing an agreement that holds up when members disagree.
Pick a Name the State Will Accept
Your LLC name has to be distinguishable from every other business entity already on file in your state. Run a preliminary search through the Secretary of State’s business database before you commit. The name also needs a designation like “LLC,” “L.L.C.,” or “Limited Liability Company” so the public knows what kind of entity they’re dealing with.
If the name is settled but you aren’t ready to file, most states will reserve it for 60 to 120 days for a small fee. That buys time to finish the operating agreement or line up capital.
Appoint a Registered Agent
Every LLC needs a registered agent in its state of formation. The agent accepts legal documents and official state correspondence, including lawsuit notices and compliance reminders. The agent must have a physical street address in the state (not a P.O. box) and be available during normal business hours.
Any member can serve, but many multi-member LLCs hire a commercial service. That keeps a member’s home address off public filings and makes sure someone is always there to accept service of process. Professional registered agent fees generally run $50 to $300 per year.
File the Articles of Organization
The document that legally creates your LLC is the Articles of Organization. Some states call it a Certificate of Formation or Certificate of Organization. You file it with the Secretary of State or equivalent office, and the form asks for the LLC’s name, principal office address, registered agent information, whether the LLC will be member-managed or manager-managed, and the names of organizers or initial members.
Fees vary widely, from as low as $35 to $500. Most states offer online filing with turnaround of a few business days, and expedited processing is usually available for an extra fee. Once approved, you receive a stamped or certified copy confirming the LLC exists. A handful of states, most notably New York, also require new LLCs to publish a formation notice in local newspapers, which can add anywhere from $50 to over $1,000 depending on local publication rates.
Write an Operating Agreement
Most states do not legally require a written operating agreement, but running a multi-member LLC without one is asking for trouble.1U.S. Small Business Administration. Basic Information About Operating Agreements The agreement is the internal contract that governs how the LLC runs, how money gets divided, and what happens when things go sideways. Without one, your state’s default LLC statute fills the gaps, and those defaults rarely match what the members actually intended.
At minimum, the agreement should cover:
- Ownership percentages and capital contributions: who put in what, and what share of the company each member holds as a result.
- Profit and loss allocation. These do not have to follow ownership percentages. An LLC can allocate profits and losses in any way the members agree to, as long as the arrangement has economic substance for tax purposes.
- Voting rights and decision-making: which decisions require a simple majority, which need a supermajority, and which require unanimous consent.
- Management structure. Member-managed means all members run the business; manager-managed means one or more designated managers handle daily operations while other members are passive investors.
- Distributions, including whether the LLC will make guaranteed tax distributions so members can cover their income tax on allocated profits.
Fiduciary Duties Between Members
In most states, LLC members and managers owe each other fiduciary duties of loyalty and care. The duty of loyalty means members can’t use company property for personal benefit, compete directly with the LLC, or divert a business opportunity that belongs to the company. The duty of care means avoiding grossly negligent or reckless decisions when acting for the LLC.
Many state statutes let the operating agreement modify or narrow these duties, though most draw the line at eliminating the duty of loyalty entirely or excusing bad faith. If your members run separate businesses in related industries, the agreement should spell out exactly what outside activity is permitted. Vague language here is a reliable source of lawsuits.
Deadlock and Buy-Sell Provisions
A 50/50 LLC with no tiebreaker mechanism is a lawsuit waiting to happen. If two equal members can’t agree on a major decision and the operating agreement says nothing about what to do, the options narrow to mediation, litigation, or dissolution. Build in a deadlock-breaker: a designated tiebreaker, mandatory mediation, or a buy-sell procedure that lets one member buy the other out at a formula price.
Buy-sell provisions matter for any multi-member LLC. They define what triggers a mandatory or optional buyout, including death, disability, divorce, bankruptcy, retirement, or voluntary withdrawal. Without them, a departing member’s interest could end up with a spouse, creditor, or estate that has no obligation to cooperate with the remaining members. Lock in a valuation method too, whether that is a fixed formula, an agreed-upon appraiser, or a periodic appraisal schedule, so nobody is arguing over price during a crisis.
Get an EIN and Open a Business Bank Account
A multi-member LLC must obtain an Employer Identification Number from the IRS. The EIN is the LLC’s federal tax ID, used for filing returns, opening bank accounts, and hiring employees. You can apply online at irs.gov and receive the number immediately, though the online system is only available during limited hours.2Internal Revenue Service. LLC Filing as a Corporation or Partnership
Open a dedicated business bank account as soon as you have the EIN. Commingling personal and business money is the fastest way to lose your limited liability protection. If a court finds that members treated the LLC’s money as their own, it can “pierce the veil” and hold members personally liable for business debts. Run business revenue, expenses, and distributions through the LLC’s own accounts, and document every member distribution.
Decide How the LLC Will Be Taxed
By default, the IRS treats a multi-member LLC as a partnership.2Internal Revenue Service. LLC Filing as a Corporation or Partnership The LLC itself pays no federal income tax. Income and losses pass through to the members, who report their shares on their personal returns. The LLC files an informational return (Form 1065) and issues each member a Schedule K-1 showing their allocated share of income, deductions, and credits.3Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
Self-Employment Tax
Members who actively participate in the business owe self-employment tax on their share of LLC profits. The combined rate is 15.3%: 12.4% for Social Security on the first $184,500 of net self-employment income in 2026, plus 2.9% for Medicare on all net self-employment income.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)5Social Security Administration. Contribution and Benefit Base Members with net self-employment income above $200,000 (or $250,000 for married couples filing jointly) also pay an additional 0.9% Medicare surtax on the excess.
Truly passive members who do not participate in management may be able to avoid self-employment tax on their distributive share under the limited partner exception, but the IRS has never issued final regulations defining which LLC members qualify as “limited partners” for this purpose, and the area remains unsettled.6Internal Revenue Service. Self-Employment Tax and Partners
The Qualified Business Income Deduction
LLC members taxed as partners may qualify for a deduction of up to 20% of their qualified business income under Section 199A. The deduction was made permanent in 2025 through the One Big Beautiful Bill Act. For 2026, it begins to phase out for single filers with taxable income above $200,000 and joint filers above $400,000, and members in certain service-based fields like law, medicine, and consulting face additional restrictions once their income exceeds those thresholds. The deduction is taken on the member’s individual return, not at the LLC level.
Electing S-Corp or C-Corp Treatment
A multi-member LLC does not have to accept partnership taxation. The members can elect to have the LLC taxed as an S-corporation by filing Form 2553 with the IRS no later than two months and 15 days after the beginning of the tax year in which the election takes effect.7Internal Revenue Service. Instructions for Form 2553 The S-corp election lets working members take a reasonable salary (subject to payroll tax) and receive the remaining profits as distributions not subject to self-employment tax. That can produce meaningful savings for profitable LLCs, but it adds payroll complexity, and the IRS scrutinizes S-corp salaries that look artificially low.
The LLC can also elect C-corporation status by filing Form 8832.8Internal Revenue Service. Form 8832, Entity Classification Election A C-corp pays corporate income tax (currently 21%) on its profits, and members pay tax again on any dividends. That double taxation makes C-corp status unattractive for most small LLCs, but it can make sense for businesses that plan to reinvest profits rather than distribute them, or that intend to seek venture capital funding.
Hit the Filing Deadlines
Form 1065 is due by March 15 for LLCs on a calendar year (the 15th day of the third month after the tax year ends). The LLC can get an automatic six-month extension by filing Form 7004, pushing the deadline to September 15.9Internal Revenue Service. Publication 509, Tax Calendars An extension to file is not an extension to pay. If individual members owe tax, they still need to pay by April 15.
The penalty for filing Form 1065 late is $255 per partner per month, for up to 12 months.10Internal Revenue Service. Failure to File Penalty For a three-member LLC that files four months late, that is $3,060. The penalty applies even if the LLC had no income, which catches a lot of new LLCs off guard. The IRS counts the number of partners at any point during the tax year, so even a member who joined in December counts.
Because LLC income passes through to members with no withholding, each member is responsible for quarterly estimated tax payments to the IRS. You generally need to make estimated payments if you expect to owe $1,000 or more when you file. Missing them triggers an underpayment penalty.11Internal Revenue Service. Estimated Taxes Many operating agreements require the LLC to distribute enough cash each quarter for members to cover these obligations, so the LLC isn’t retaining all its profits while members scramble for personal funds to pay the IRS.
Keep the LLC in Good Standing
Nearly every state requires LLCs to file an annual or biennial report. The report updates the state with current information about the LLC’s address, members or managers, and registered agent. Missing a filing can mean late fees, loss of good standing, or eventually administrative dissolution. Fees vary by state and may be flat or based on factors like the number of members.
Most states and many municipalities also require business licenses or permits depending on your industry and location. Check with your state’s business licensing office and your local city or county clerk to confirm what applies.
Operating in More Than One State
If your LLC does business in a state other than where it was formed, you will likely need to register as a “foreign LLC” there. That typically means filing a registration form, appointing a registered agent in the new state, and paying an additional fee. The definition of “doing business” varies, but generally includes having employees, an office, or making regular sales in the state. Operating without proper registration can bring fines and leave you unable to enforce contracts in that state’s courts.
Watch for the Securities-Law Issue
Membership interests in a manager-managed LLC can be classified as securities under federal law. Courts apply a four-part test asking whether someone invested money in a common enterprise expecting profits derived primarily from the efforts of others. In a manager-managed LLC where most members have no real say in daily operations, their interests can look like the kind of passive investment securities laws are designed to regulate.12U.S. Securities and Exchange Commission. Exemption for Limited Offerings Not Exceeding $10 Million – Rule 504 of Regulation D
Member-managed LLCs are far less likely to run into this problem, because all members participate in management. Even so, if the agreement concentrates real control in one or two members while the rest are passive in practice, a court could still find a security based on the economic reality. If your LLC is raising capital from members who will not be actively involved, talk to a securities attorney before accepting the money. Regulation D provides exemptions from full SEC registration, but you still need to file a Form D notice and comply with state securities laws.
