How to file a DBA in Arizona step by step


What is a DBA in Arizona?

A DBA (Doing Business As), also called a trade name or assumed name, allows your business to operate under a name different from its legal name. Registering a DBA in Arizona is a smart move if you want to create a recognizable brand, launch a side venture, or operate under multiple names without forming multiple companies.

👉 Example: The Works – Gilbert is a DBA. Our legal entity name is The Works East Valley LLC.

Many small businesses, freelancers, and startups use DBAs when they want to look more professional to clients or banks without committing to a full LLC structure right away.

DBA vs LLC vs Sole Proprietorship in Arizona

    • DBA (Trade Name): A DBA is only a registered name. It doesn’t create a separate legal entity or provide liability protection, but it lets you legally advertise, brand, and open bank accounts under that name.
    • LLC (Limited Liability Company): Provides personal asset protection. If your business is sued or goes into debt, your personal property (like your home or car) is shielded. Arizona LLCs are flexible, affordable, and widely recommended for growing businesses.
    • Sole Proprietorship: The easiest and most informal business structure. The business and owner are legally the same. No separate filings are required unless you want a DBA, but you’re personally responsible for debts and obligations.

💡 Tip: Many Arizona business owners start as sole proprietors with a DBA and later transition to an LLC once revenue increases or liability risk grows.

How to File a DBA in Arizona (Step-by-Step)

Registering a DBA in Arizona is done through the Arizona Secretary of State. Here’s the process:

  1. Pick a Unique Name: Your DBA cannot be misleading. For example, if you are not incorporated, you cannot call your business “ABC Corporation.”
  2. Check Availability: Search both the Arizona Corporation Commission database and the Trade Name & Trademark search to confirm your name isn’t already taken.
  3. File Online or by Mail: Applications can be submitted online (fastest) or by mailing the form to the Secretary of State’s office. Online filing is typically approved in just a few days.
  4. Pay the Filing Fee: The standard fee is $10. Expedited processing is available for $35. This is one of the lowest DBA filing fees in the country.
  5. Publication Requirement: Corporations and LLCs must publish a notice of formation in a local newspaper within 60 days of approval. Sole proprietorships and partnerships may also face publication requirements depending on the county.

✅ Once approved, your DBA is valid for five years. You’ll need to renew it before expiration if you want to continue using the name.

Forming an LLC in Arizona

How to start an LLC in Arizona

Why Choose an LLC? LLCs are the go-to option for small-to-medium businesses in Arizona. They combine liability protection with tax flexibility, making them more secure than sole proprietorships but easier to maintain than corporations.

Steps to Form an LLC in Arizona:

  • File Articles of Organization with the Arizona Corporation Commission.
  • Appoint a statutory agent (registered agent) with a valid Arizona address.
  • Pay the filing fee ($50 standard, $85 expedited).
  • Publish a notice of formation in a newspaper (if required by your county).

Many entrepreneurs also choose to file a DBA in addition to their LLC—allowing them to operate under multiple brand names while keeping liability protection.

Sole Proprietorships in Arizona

A sole proprietorship is the easiest business type to start in Arizona. You don’t need to register with the state unless you want to use a trade name. However, you are personally responsible for any debts, contracts, or legal issues. This makes liability a key risk factor.

For many freelancers, consultants, and independent contractors, a sole proprietorship plus a DBA is enough to get started. But if your business grows or involves higher liability (like retail, food service, or property rentals), upgrading to an LLC is often a wise next step.
