To file a DBA in Las Vegas, fill out Clark County’s Certificate of Assumed or Fictitious Name, sign it, and mail it or take it to the County Clerk with $25. Nevada gives you one month after you start using the name. After that, make sure your Google Business Profile, your website, and your directory listings all show that exact name.
That’s the short version, but the details matter. Get the DBA wrong and you may not be able to sue a client who won’t pay. And if your name doesn’t match across the web, your local rankings can suffer.
This is general information, not legal advice. Fees and forms change, so confirm with the Clark County Clerk or a Nevada attorney before you file.
Do You Need a DBA in Nevada?
You probably do if customers know you by any name other than your legal one. Nevada requires a certificate from anyone doing business under a name that is different in any way from the legal name of each owner (NRS 602.010). You file it with the county clerk in every county where you do business.
- Sole proprietor: Jane Smith runs “Smith Design Studio.” She needs a DBA.
- LLC: “Smith Plumbing, LLC” advertises as “Valley Drain Co.” It needs a DBA.
- No DBA needed: the business uses its exact legal name everywhere.
The deadline is short. You have to file no later than one month after you start doing business under the name (NRS 602.030).
What Happens If You Skip It
- You can’t sue to collect. You can’t start or continue a lawsuit over a contract made under the assumed name unless the certificate was filed before the suit began (NRS 602.070). That includes chasing an unpaid invoice.
- It’s a crime. Doing business without following the chapter is a misdemeanor (NRS 602.090).
How to File a DBA in Clark County, Step by Step
1. Search the name
Start with the Clark County fictitious name search. Clark County says fictitious firm names are not exclusive, so a match won’t block your filing. It is a warning sign for brand confusion, though.
2. Pick the right form
The Clark County Clerk has a separate form for each owner type:
- Sole Proprietorship: one owner.
- General Partnership: two or more owners. Each owner completes a form.
- Registered Business Entity: corporations, LLCs, and limited partnerships on file with the Nevada Secretary of State.
- Trust: one form per trustee, plus a copy of the trust.
- Series LLC: for a series created by a parent LLC.
3. Fill it in exactly
Enter your entity’s name exactly as the Secretary of State shows it. The person who signs has to be listed on the entity’s state registration. If they aren’t, a notarized authorized signer affidavit must go with the form (Registered Business Entity form).
If you make a mistake, print a new form. The Clerk won’t accept cross-outs, correction fluid, or correction tape.
4. Sign the original (no notary needed)
Clark County doesn’t require a notary for these forms. You do need to send the original signed form, because the Clerk doesn’t accept copies.
5. File it and pay $25
- By mail: Clark County Clerk’s Office, Attn: FFN, Box 551604, Las Vegas, NV 89155-1604. Make checks or money orders payable to County Clerk.
- In person: at a Clerk office. Check the Clerk’s locations and hours first.
- Online: not available. The Clerk doesn’t offer online filing for these forms.
The $25 fee covers a new or renewal filing and includes one uncertified copy. Card payments add a 2% + $1.25 processing fee.
6. Put the renewal on your calendar
A Clark County DBA is valid for five years from the filing date. The Clerk mails a renewal notice about 60 days before it expires, but only to the address on file, so keep that address current.
LLC or Corporation? Keep Your State Filing Active First
The Clerk rejects a Registered Business Entity filing if the entity doesn’t have an active registration with the Nevada Secretary of State. For an LLC, staying active means filing the annual list by the last day of your anniversary month (NRS 86.263). You renew your state business license at the same time (NRS 76.130).
Miss that deadline and the LLC goes into default. That adds a $75 list penalty (NRS 86.272) and a $100 license penalty (NRS 76.130). Check your status in ORION, the Secretary of State’s business portal, before you file the DBA.
Make Google Match Your DBA: A NAP Checklist
Filing the DBA is half the job. The other half is making sure every place your business appears online uses the same name, address, and phone number (NAP).
Google’s guidelines say your profile name should reflect your real-world name, as used consistently on your storefront, website, and stationery. Google also says local results depend partly on how well-known a business is, based on things like how many websites link to it and how many reviews it has.
- Name: use the name on your signage and website on Google, which is often your DBA. Leave off LLC or Inc. unless your signage, business cards, and invoices show it. Google only allows legal terms in a profile name when real-world proof shows them.
- Address: use one format everywhere. Google asks for a precise, accurate address and puts a suite number in Address Line 2.
- Phone: use one main number on every listing.
- Website footer: show both names, for example “© 2026 Smith Plumbing, LLC dba Valley Drain Co.”
- Schema markup: set your Organization “name” to the brand and “legalName” to the registered name. Schema.org defines legalName as the official name of the organization, such as the registered company name.
- Old listings: find directory profiles that show an old name, address, or website, and update or remove them.
- Proof on file: for service-area businesses, Google’s video verification accepts documents that show your business name, such as a business permit, invoice, or utility bill. Keep your filed DBA certificate with them.

Common DBA Mistakes That Cost You
- Filing in one county when you work in several. Nevada requires a certificate in each county where you do business under the name.
- Letting it lapse. The certificate expires five years after filing, so renew it before that.
- Thinking a DBA protects your brand. It doesn’t, because Clark County fictitious names aren’t exclusive.
- Updating your website but not your listings. A new name or suite number on your site with old data everywhere else sends Google mixed signals. That’s one of the reasons Las Vegas businesses disappear from Google.
- Filing for an LLC that’s in default. The Clerk will reject it, so fix your state status first.

Frequently Asked Questions
Do I need a DBA if I have an LLC in Nevada?
Only if the LLC does business under a name that differs from its registered name. Nevada requires a certificate with the clerk of each county where you use that name, filed no later than one month after you start (NRS 602.010 and 602.030). An LLC that uses its exact legal name doesn’t need one.
How much does a DBA cost in Clark County?
Clark County charges $25 to file a new or renewal fictitious firm name certificate, and that includes one uncertified copy. Paying by card adds a 2% + $1.25 processing fee. The certificate is valid for five years, and the Clerk mails a renewal notice about 60 days before it expires.
Can I file a DBA online in Clark County?
No. The Clark County Clerk accepts fictitious firm name filings only by mail or in person, and it needs the original signed form, not a copy. You don’t need a notary. By mail, send it to Clark County Clerk’s Office, Attn: FFN, Box 551604, Las Vegas, NV 89155-1604.
Does a DBA protect my business name?
No. Clark County says fictitious firm names are not exclusive, so another business can file the same name. A DBA puts your trade name on public record and meets Nevada’s filing rule. Protecting a brand is a separate step, usually a trademark filing.
Should my Google Business Profile use my LLC name or my DBA?
Use the name customers actually see. Google says your profile name should reflect your real-world name as used consistently on your storefront, website, and stationery. If that’s your DBA, use it on Google, and leave off LLC unless your signage and invoices show it.
