Key Takeaways

  • A one member LLC (or single-member LLC) offers limited liability and tax flexibility while remaining simple to manage.
  • Despite fewer filing requirements, owners must still complete critical steps like filing Articles of Organization, obtaining an EIN, and meeting state-specific compliance obligations.
  • An operating agreement, though not always required, strengthens liability protection and can help avoid “piercing the corporate veil.”
  • Additional compliance tasks include registering for state taxes, filing annual or biennial reports, maintaining business records, and keeping personal and business finances separate.
  • Certain professions may require forming a professional LLC (PLLC) instead of a standard one member LLC.

Single-member LLC filing requirements are similar to the requirements for multiple-member LLCs; both types require articles of organization to be filed for the LLC's formation, and both require owners to report profits and losses on personal tax returns. There are some important differences, though.

LLCs were created from partnerships, and liability protection was added. The IRS does not officially recognize single-member LLCs. It only allows LLCs that have at least two owners. You can, however, form a single-member LLC, which is abbreviated as SMLLC. It has some advantages over sole proprietorships, namely limited liability and the appearance of legitimacy.

The liability protection that SMLLCs offer is not as strong and undisputable as a traditional LLC, but there are still good reasons to form one:

  • You can add “LLC” to your business name, which makes you appear more professional and credible to vendors, suppliers, customers, and clients.
  • It's easy to become an S corporation instead if you choose.
  • Single-member LLCs can choose to avoid self-employment tax by electing to become an S corporation retroactively for the year.
  • Owners of single-member LLCs protect their personal assets from business liabilities.
  • Switching to a traditional LLC is a simple process; you can give a very small amount of your business ownership to a family member.
  • The IRS classification of “disregarded entity” means that single-member LLC owners are taxed just like sole proprietorships, and any profit or loss is reported on their personal tax returns using Schedule C. The LLC does not file its own return.
  • Unlike corporations, SMLLCs do not need to file annual reports or meeting minutes.

Why SMLLCs Can Be Problematic

While single-member LLCs are similar in most ways to traditional LLCs, there are some important differences. The most common reason people choose to form LLCs is for the liability protection, referred to as “charging order” protection.

LLCs and corporations both add liability protection for businesses so that owners' personal assets will not be taken by creditors to settle the debts or lawsuits against the business. However, an LLC adds another level of protection called the charging order. This means that LLC partners are protected from the actions of other owners.

If an LLC owner was sued or had unpaid personal debts, his or her creditor would not be able to take away his membership interest in the LLC, even though that would be considered an asset. Doing so would mean the other LLC members would have to deal with a new LLC owner, whether they wanted to or not. Therefore, federal law only allows creditors to seize the unfortunate member's profits from the LLC.

If there is only one member, this is irrelevant. If you, as the owner of an SMLLC, are sued or have unpaid debts, there is nothing to stop your creditor from taking away your business assets because there are no partners' wishes to consider.

This problem can easily be avoided, however, by sharing a small amount of your membership interest in the LLC with another individual. This may not be your husband or wife, because the IRS considers married couples to be one single member. Instead, you may choose one of your children or another close relative.

Doing so does not mean you need to give up control of your LLC, or even to allow their input in running it. You can make sure your partner remains a silent partner by creating a manager-managed LLC and appointing yourself as the manager.

Filing and Compliance Steps for a One Member LLC

Forming a one member LLC is relatively straightforward, but proper filing and ongoing compliance are critical to maintaining limited liability protection and good legal standing. Here are the main steps and requirements owners must follow:

  1. File Articles of Organization
    Submit Articles of Organization (sometimes called a Certificate of Formation) with the Secretary of State or equivalent agency. This foundational document establishes your LLC’s legal existence and must include key details like the company name, registered agent, and principal address.
  2. Choose a Registered Agent
    Most states require a registered agent to receive legal and tax correspondence on behalf of the LLC. The agent can be the owner, another individual, or a professional registered agent service.
  3. Obtain an Employer Identification Number (EIN)
    Even though a one member LLC is treated as a disregarded entity for federal tax purposes, you’ll still need an EIN from the IRS if you plan to hire employees, open a business bank account, or elect corporate taxation.
  4. File Initial and Annual Reports
    Many states require LLCs to file an initial report shortly after formation and annual or biennial reports thereafter. These filings keep your company in good standing and often involve a small fee.
  5. Register for State and Local Taxes
    If you sell goods or services, have employees, or operate in certain industries, you may need to register for sales tax, payroll tax, or other state-level business taxes.
  6. Maintain Proper Records
    Keep accurate financial and operational records, including meeting minutes (if applicable), membership interest transfers, and key business decisions. While these aren’t always required, they strengthen the liability shield.
  7. Separate Business and Personal Finances
    One of the most common mistakes that jeopardize limited liability is commingling personal and business finances. Open a dedicated business bank account and use it exclusively for business transactions.

Operating Agreements

Operating agreements are usually not required to be filed, but they are valuable documents nonetheless. These are the company's bylaws and contain important rules and guidelines about how the business will function both day-to-day and when certain situations arise in the future.

Single-member LLCs have almost no protection against lawsuits without an operating agreement because so few records are required to be filed and maintained. There are only three states in the U.S. that give SMLLCs the same protection as multi-member LLCs.

Along with taking on a silent partner, you can protect yourself by creating an operating agreement and keeping annual company minutes along with any other relevant legal documents. These may reflect the fact that the LLC is actually a two-member entity.

Additional Considerations for One Member LLCs

While the basic filing requirements are fairly standard, certain nuances apply specifically to one member LLCs:

  • Professional Restrictions: Some states restrict certain licensed professions (like law, medicine, or accounting) from forming standard LLCs. Instead, these professionals may need to form a professional limited liability company (PLLC) or professional corporation.
  • Tax Elections: By default, a one member LLC is taxed as a sole proprietorship. However, you may choose to be taxed as an S corporation or C corporation if doing so offers tax advantages, such as reduced self-employment taxes or retained earnings benefits.
  • Foreign Qualification: If your LLC will operate in multiple states, you may need to register as a “foreign LLC” in each additional state.
  • Dissolution and Compliance: If you decide to close your business, you must formally dissolve the LLC with your state to avoid ongoing tax and filing obligations.

These additional steps help ensure your one member LLC remains legally compliant, protects your liability shield, and positions your business for long-term success.
