A "doing business as," or DBA, under LLC helps a lot of business owners to properly manage their finances and to ensure that their business and personal finances are separate. Here are things to know on how to add a DBA under an LLC.

What Is a Limited Liability Company (LLC)?

Before anything else, Limited Liability Company (LLC) is a way for business owners to avail the pass-through tax advantages and to prevent personal liability for their business's debts. LLCs are required by state laws to have their operation under the legal name mentioned in their Articles of Organization. To ensure that the public will identify and distinguish the company's legal structure, an LLC's legal name should be unique from other businesses operating in the state.

LLC Formation

With regard to forming an LLC, every state has its own policies and requirements such as naming requirements. The LLC name indicated on the filed document submitted and accepted by the state will be the legal name of the new business entity. The company needs to ensure that all legal documents involving the LLC should indicate the legal name filed and approved by the state. Some of these are tax filings and applications for business licenses and loans.

DBA Registration

A "doing business name," or DBA, is a fabricated name used by a business to identify its products and services. A single LLC entity can operate with multiple businesses using a DBA. For a DBA to be used legally by the business owners, they are required to register the name in accordance with state laws where the business operates. A penalty is imposed on businesses when they fail to register a DBA prior to operations. Since multiple DBAs can be registered under a single LLC, each of the DBAs needs to be registered separately. One of the imposed rules on using DBA is to ensure that there will be no two businesses having the same DBA. In addition, some state laws require that a DBA should only be registered once in a state with a state-level registration system.

Benefits and Limitations of Using a DBA Under an LLC

A DBA (Doing Business As) allows an LLC to conduct business under a different name without forming a separate legal entity. This offers several advantages:

Benefits:

  • Branding Flexibility: A single LLC can operate multiple businesses under different names, avoiding the need to form multiple LLCs.
  • Marketing Advantages: A DBA enables businesses to choose a market-friendly, memorable name for specific products or services.
  • Easier Business Expansion: If an LLC wants to enter new markets with a different brand identity, a DBA is a cost-effective alternative.
  • Simplified Banking and Transactions: A DBA allows an LLC to receive payments under the assumed name rather than the formal LLC name.

Limitations:

  • No Legal Protection: A DBA does not provide additional liability protection beyond what the LLC already offers.
  • No Separate Taxation: Since a DBA is not a separate legal entity, it does not affect how an LLC is taxed.
  • State-Specific Compliance: DBA registration and renewal requirements vary by state, sometimes requiring periodic renewal and local-level filings.

How to Add a DBA to an LLC?

Registration of a DBA or a fictitious business name depends on the state where it operates. For some states like New Mexico, Kansas, Alabama, and Mississippi, filing for a DBA is not required by state law. For a comprehensive enumeration of requirements on filing a DBA, a list is provided by the U.S. Department of Commerce. Here's the process on how to register a DBA:

  • Get copies of a DBA registration form.
  • Accomplish and complete the DBA registration form and don't forget to provide the details of your LLC.
  • Submit it to the appropriate agency.

On the registration process, you need to provide more than one DBA name you intend to use. These alternatives will be used just in case the name has already been chosen by a different company. Apart from the mentioned steps, one is also required to state other information like personal details, name, and address including information about your LLC such as the registered agent and office address of your LLC. Submit the DBA registration form to the appropriate agencies on the state, country, or local government. Getting a DBA registered depends on the state but usually costs from $10 to $50, as of 2010.

Steps to Ensure Compliance When Using a DBA

o use a DBA legally and avoid potential penalties, an LLC must adhere to state-specific rules. Follow these compliance steps:

  1. Check Name Availability – Ensure the chosen DBA is not already in use by another business in your state.
  2. Register the DBA Properly – Some states require local (county or city) and state-level filings.
  3. Update Business Licenses & Permits – A DBA may require updates to existing business licenses, zoning permits, and industry-specific registrations.
  4. Maintain Renewals & Filings – Some states require DBA renewals every few years, while others treat the registration as indefinite.
  5. Maintain Proper Contracts – Ensure that contracts, invoices, and official documents clearly indicate that the LLC is the legal entity operating under the DBA.

Do You Need a DBA or LLC?

An individual operating as a sole proprietor might want to get a DBA under his name so he can do business transactions using a business name. If clients are required to paychecks using a business name and not your own, then a DBA is required. Having a DBA will force your personal and business finances to be separate, which will be a great help during tax filings. 

DBA vs. LLC: Choosing the Right Business Structure

Understanding the key differences between an LLC and a DBA can help businesses make an informed decision:

Feature LLC DBA
Legal Protection Provides liability protection for owners No liability protection
Registration Requires formation paperwork with the state Requires separate registration at the state/county level
Tax Treatment Can be taxed as a pass-through entity or corporation No effect on tax status, as it’s not a separate legal entity
Business Name Use Can operate under its legal name or register a DBA Only allows the use of an alternate business name
Costs Higher filing and maintenance costs Lower costs compared to forming an LLC

When to Choose an LLC:

  • If you need limited liability protection to separate personal and business assets.
  • If you plan to attract investors or bring on multiple owners.

When to Choose a DBA:

  • If you already have an LLC but want to operate multiple businesses under one entity.
  • If you are a sole proprietor and want to operate under a business name without forming an LLC.

Maintaining LLCs and DBAs

For LLCs and DBAs to continue their operations, they need to comply with state laws to ensure proper maintenance and use of LLC and DBA. Some states have added requirements such as filing a Biennial Report in Iowa or an Annual List in Nevada. Failure to comply might lead to the forfeiting of rights to business or monetary penalties. DBAs are valid for four to five years but need to be renewed upon its expiration to ensure that other business won't use it.

How to Maintain an Active DBA

Maintaining an active DBA is essential to avoid penalties or loss of business rights. Here’s what LLC owners should do:

  • Monitor Renewal Dates: Many states require DBAs to be renewed every 3-5 years, while others may require annual filings.
  • Update Business Records: If an LLC changes its address, ownership structure, or other key details, it may need to update the DBA registration.
  • Comply with State-Specific Rules: Some states require public notices when registering or renewing a DBA.
  • Keep Business Finances Separate: Even though an LLC can use multiple DBAs, each should have its own accounting and banking records for tax clarity.

Failure to maintain a DBA properly can result in legal fines or the cancellation of the assumed business name.

Personal Liability

The main reason for forming an LLC is to protect your personal assets from the liabilities of the business. One should also be wary when using a DBA in conjunction with an LLC for you not to confuse the usage of the business's legal name (LLC) and the assumed name (DBA). This is important because a DBA doesn't provide a personal liability protection and an individual might find himself responsible for business debts if legal documents are sealed in a manner that confuses whether you or the LLC is using the DBA.
