Can a Professional Practice Use a DBA?
Yes, a licensed professional practice can generally use a DBA, but many licensing boards require their own approval on top of the standard state or county filing. California, for example, requires physicians to hold a separate Fictitious Name Permit from the Medical Board before advertising under a practice name, while its Board of Accountancy requires CPA sole proprietors to get board approval for a practice name. Check your specific profession's board, since the rule and the fee vary.

Comprehensive Guide
Why Licensed Professions Often Have an Extra Layer
Most businesses only need to register a DBA with their state or county filing agency. Licensed professions, such as medicine, law, dentistry, and public accounting, often add a second layer: the licensing board itself regulates what name a licensee can practice and advertise under, separate from whatever the state's general business filing office requires. This exists because a practice name can mislead the public about who's actually licensed and accountable for the services provided.
California's Medical Board Fictitious Name Permit
California is a useful, well-documented example of how this works in practice. Per the Medical Board of California, using a fictitious, false, or assumed name, alone, with a group, or as the name of a professional corporation, in any public communication, advertisement, sign, or announcement of a physician's practice without a Fictitious Name Permit is unprofessional conduct. A permit is required for a practice name like "Sunrise Medical Group" that doesn't consist of the physician's own name. The application carries a $70 fee, and the Medical Board requires renewal every two years.
When No Extra Permit Is Needed
The same Medical Board guidance carves out an exception: no permit is required if only the physician's own name or surname is used, followed by a term like "Medical Doctor," "M.D.," "Medical Corporation," "Professional Corporation," or similar designators. In other words, "Dr. Jane Smith, M.D." needs no special permit, while "Sunrise Family Medicine" does, because the second name doesn't identify the licensed individual behind it.
Accountancy Firms Face a Different, Stricter Rule
Other professions handle this differently. California's Board of Accountancy requires a sole proprietor CPA who wants to practice under a name other than their own to register that name and get it approved by the Board before practicing or holding it out to the public; a name like "Smith Accountancy" needs that approval. For an accountancy corporation, California doesn't issue a separate "fictitious name permit" at all; the corporation practices under its registered corporate name as approved, period, with no DBA alternative available the way a sole proprietor has.
What This Means for Your Practice
If you're a licensed professional considering a DBA or practice name, don't assume your state's general DBA filing process is the whole story. Start with your profession's licensing board, not just the Secretary of State or county clerk, and ask specifically whether a fictitious or assumed name requires board approval, a separate application, a fee, or periodic renewal on top of any general DBA filing. The requirements, fees, and even whether a DBA is available to your type of practice entity at all, vary by both profession and state.
Naming Rules Still Apply on Top of Licensing Rules
Even after board approval, a practice name generally still can't be false or misleading about the services provided or imply a connection to a government agency or a different profession entirely. Some boards also restrict using a deceased or departed partner's name in an ongoing practice name without disclosure. Review your specific board's advertising and naming rules in addition to the fictitious name permit requirement itself.
Entity Structure Adds Another Layer
Many states require licensed professionals to organize as a professional corporation (PC) or professional limited liability company (PLLC) rather than an ordinary corporation or LLC. If your practice is organized this way, a DBA or fictitious name sits on top of that entity structure the same way it would for an ordinary LLC, registered with your state's general DBA filing process in addition to whatever your licensing board requires. See our guide on how to file a DBA for that general process once you've cleared your board's requirement.
Practical Considerations
Check Before You Advertise, Not After
Using an unapproved practice name in advertising, signage, or public communications can itself be the violation, regardless of whether you've filed the general state DBA. Clear your name with your licensing board before putting it on a sign, website, or business card, not after.
Group Practices and Partnerships
A group practice with multiple licensed professionals often faces its own naming rules, such as requiring every named partner to be currently licensed and practicing with the group, or restricting how a departed partner's name can continue to be used. Confirm your board's specific rule for group or partnership names, which can differ from the rule for a solo practice.
Renewal Is Often Separate From Your DBA Renewal
If your board issues its own fictitious name permit, like California's two-year Medical Board renewal, track that renewal date separately from any general state or county DBA renewal. The two can run on different schedules, and letting either lapse can affect your ability to keep advertising under the practice name.
Not Legal Advice
Rules for professional practice names vary by state and by profession, and the consequences for operating under an unapproved name can include discipline from your licensing board. Talk to a business attorney familiar with your profession's regulations before finalizing a practice name.

Frequently Asked Questions
Does a doctor need a special permit to use a practice name?
In California, yes. The Medical Board of California requires a Fictitious Name Permit before a physician advertises under any name other than their own, with an exception for using just the physician's name plus a term like M.D. or Professional Corporation.
Can a CPA practice under a fictitious business name?
It depends on the state and structure. In California, a sole proprietor CPA must register a practice name and get Board of Accountancy approval, while an accountancy corporation practices only under its registered corporate name with no separate fictitious name option.
Who regulates a professional practice's DBA, the state or the licensing board?
Often both. A general DBA filing is made with the state's or county's standard filing agency, but many licensed professions also require separate approval from their own licensing board before the name can be used publicly.
Can I just use my own name instead of getting a DBA permit?
Often, yes. Several boards, including California's Medical Board, don't require a special permit if you use only your own licensed name, optionally followed by a professional designation, rather than a separate practice brand name.
