DBA vs LLC: Which One Does Your Small Business Need?

Is it better to have a DBA or an LLC?

The answer depends on how much risk the business carries. The SBA says sole proprietorships “can be a good choice for low-risk businesses and owners who want to test their business idea before forming a more formal business.” The SBA says LLCs “can be a good choice for medium- or higher-risk businesses, owners with significant personal assets they want protected, and owners who want to pay a lower tax rate than they would with a corporation.”

A DBA does not change which of those two you are. A sole proprietor with a DBA is still a sole proprietor. An LLC with a DBA is still the same LLC. So the first decision is sole proprietor or LLC, and the DBA question comes second. Our guide on when you need an LLC covers the sole proprietor side in more detail.

1. 1Could a customer, a contract, or a debt reach your savings or your home? If yes, read the SBA’s description of LLCs first.
2. 2Do you only want a brand name on your sign, website, and invoices? A DBA can give a sole proprietor or an LLC that name.
3. 3Are you testing an idea with little risk? The SBA describes a sole proprietorship as a fit for that stage.
4. 4Do you want a business bank account in the brand name? The SBA says getting a DBA and an EIN (employer identification number) “allows you to open a business bank account.”

What are the disadvantages of a DBA?

The limits of a DBA come from what it is. A DBA is a name, and the owner behind it stays the same. The official sources we read point to five limits.

• No liability protection. The SBA says a sole proprietor “can be held personally liable for the debts and obligations of the business.” A DBA does not change that.
• No exclusive right to the name. The SBA says multiple businesses can use the same DBA in one state, and that “trademark infringement laws will still apply.”
• Renewals. Los Angeles County says “FBN’s expire 5 years from the date of filing.” Texas says an entity’s assumed name certificate lasts for “a term not to exceed ten years.”
• Publication and paperwork. Los Angeles County requires the filed statement to be “published once per week for four consecutive weeks in an adjudicated newspaper in Los Angeles County.” The county also requires a notarized Affidavit of Identity.
• Your address goes on the filing. Los Angeles County requires “All owners and their business mailing addresses” to be listed.

Skipping a required DBA filing has its own risk. The Texas Secretary of State says the Business and Commerce Code “provides both civil and criminal penalties for failure to file the assumed name certificate.”

Do DBAs get tax write-offs?

A DBA does not file its own tax return, so the DBA itself gets no deductions. The owner behind the DBA does. The IRS page for sole proprietorships lists Form 1040 with Schedule C, Profit or Loss from Business, for income tax. The same page lists Schedule SE for self-employment tax.

The usual deduction rules apply to the owner’s business. IRS Publication 334 says: “To be deductible, a business expense must be both ordinary and necessary.” The publication defines an ordinary expense as “one that is common and accepted in your field of business.” The same test applies whether or not the business uses a DBA name.

An LLC’s federal tax treatment depends on how many members it has and what it elects. The IRS says “an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and affirmatively elects to be treated as a corporation.” For an individual owner, the IRS says the LLC’s activities “will generally be reflected on” Schedule C, Schedule E, or Schedule F. For an operating business, that is usually Schedule C. The IRS also says a domestic LLC “with at least two members is classified as a partnership” unless it elects to be treated as a corporation.

So, by default, a one-owner LLC owned by an individual and a sole proprietor with a DBA generally use the same federal income tax form. The IRS says the individual owner of a single-member LLC “is subject to the tax on net earnings from self employment in the same manner as a sole proprietorship.” Payroll is one place where the LLC differs. The IRS says a single-member LLC “is still considered a separate entity” for employment tax and certain excise taxes.

State taxes can also differ. For example, the Texas Secretary of State’s LLC instructions say “LLCs are subject to a state franchise tax.”

What DBA and LLC filings cost: two official examples

There is no single national price. The SBA says DBA requirements “vary by business structure as well as by state, county, and municipality.” Here are the fees from two official sites we read on October 25, 2026.

In Los Angeles County, California, a first-time fictitious business name filing costs $26 for one business name and one registrant. Each additional business name or registrant adds $5. The county also requires newspaper publication. The county fee page does not list what publication costs.

In Texas, the Secretary of State charges $300 to file a certificate of formation for an LLC. An LLC that also uses an assumed name pays $25 to file an assumed name certificate.

These numbers are filing fees only. They do not include publication, a registered agent, or yearly state filings, and other states and counties charge different amounts. Our guide to DBA address rules in five states compares filing levels and renewals state by state.

Can an LLC also have a DBA?

You can file a DBA without an LLC, as the SBA notes for sole proprietors. You can also have both. An LLC can do business under a name other than its legal name by filing a DBA for itself.

Texas shows how this works. The Secretary of State says an LLC that “regularly conducts business or renders a professional service in this state under a name other than its legal name” must file an assumed name certificate with the Secretary of State. The Secretary of State also says a 2019 law, HB 3609, removed “the county-level filing requirement” for LLCs and other entities.

Los Angeles County also accepts fictitious business name statements from LLCs. For an LLC, the county says a manager or officer signs. The county also requires a print-out from the California Secretary of State showing the LLC’s current existence and good standing.

A DBA you filed as a sole proprietor does not move to a new LLC on its own. The LLC is a different owner. Our guide to moving a DBA to an LLC explains what happens to the name.

Which address each filing asks for

Every filing above asks for an address. Two of them are made to put information in front of the public. Los Angeles County requires the filed statement to be published in a newspaper. In Texas, the Secretary of State says the effect of an assumed name filing “is to give notice to the public that the entity is conducting business under that name.”

If you work from home, the county and Texas filings above can put your home address on a public record. Schedule C is part of your tax return, not a public record. If you use a separate business address instead, check that each filing accepts that kind of address. The Texas rows above show that one form can hold two address fields with different rules. On Form 205, the initial mailing address may be a post office box, but the registered office “may not be solely a mailbox service or telephone answering service.” Before you list a new address, our free address checker shows how USPS classifies it.
