When starting or expanding a business in Indiana, you may find the need to operate under a name that is different from your legal business name. That is when filing a DBA in Indiana becomes necessary. DBA, or “Doing Business As,” is the formal process by which businesses adopt a trade name while retaining their existing legal business structure. Whether you are a sole proprietor launching a new side business or an LLC looking to add a new brand, this guide has everything you need to complete the process correctly and, most importantly, efficiently.

Who Needs to File a DBA in Indiana?

Not all Indiana business owners need to file a DBA, but many do. There is a very simple rule to figure it out: if your business is operating under a name other than its legal business name, you must have a DBA registration.

Business Type	Needs a DBA If…
Sole Proprietor	Using any name other than their full legal name
Partnership	Not including all partners’ surnames in the business name
LLC / Corporation	Operating under a brand name different from the registered name
Expanding Business	Launching a new service line or brand under a different name

For example, say you are a freelance designer named Mark Rivera. If you call yourself “Rivera Creative Studio,” you do not need a DBA. However, if you are calling yourself “Pixel and Co. Design,” you do need a DBA.

Is Filing a DBA in Indiana Legally Required?

Yes. Indiana requires any business operating under a name other than its legal business name to formally register it. Skipping this step carries real financial and legal consequences.
Without a valid DBA, your business cannot:

• Open a bank account under the trade name
• Sign or enforce contracts using that name
• Receive payments made to the business name
• Appear credible and professional to clients and vendors

Two exceptions apply:

• Sole proprietors whose business name includes their own surname (e.g., “Rivera Consulting” for Mark Rivera)
• Churches, lodges, or business associations that have already filed a declaration of trust with the county recorder

If neither exception applies, filing a DBA in Indiana is a legal obligation, not a choice.

How to File a DBA in Indiana: Step-by-Step

Indiana has a split filing system based on your business type:

• LLCs, Corporations, LLPs, and LPs file with the Indiana Secretary of State using the INBiz online portal
• Sole Proprietors and General Partnerships file with the county recorder’s office in the county where your business operates

Step 1: Search Name Availability
Before anything else, find out if your desired DBA name is already taken. Use the INBiz Business Entity Name Search tool, the Indiana Trademark Search, and the USPTO’s Trademark Electronic Search System (TESS) to look for any possible conflicts.

Step 2: Prepare Your Information
You should prepare the following details ahead of time:

• Legal name of the entity
• Intended DBA (assumed) name
• Physical address of the business
• Full names and addresses of all owners or partners
• Description of the business activity

Step 3: Submit the Registration Form

• LLCs/Corporations: Log into your INBiz account, navigate to Online Services, find the Secretary of State section, and select the filing for Assumed Name
• Sole Proprietors/Partnerships: Visit your county recorder’s office for the appropriate form and verify their submission procedures, whether online, by mail, or in person

Step 4: Pay the Filing Fee

The filing fee for your DBA is determined by the state of Indiana and by the type of business you operate. See the cost section below for a full breakdown of the variances.

Step 5: Save Your Certificate

Once your filing has been accepted, keep your assumed name certificate along with your other important business documents. You will need it when opening a business bank account, signing contracts, and protecting your business from potential legal disputes.

Key Benefits of Registering a DBA in Indiana

Filing a DBA in Indiana supports business growth while keeping you legally compliant. Here is what you gain:

• Open a business bank account under your trade name. Most banks require a registered DBA
• Build brand credibility with customers, vendors, and suppliers
• Market under a name that resonates with your audience, not just your legal entity name
• Run multiple brands under one legal entity, no new company formation needed
• Expand into new markets or service lines without changing your business structure

Example: “Hartwell Home Services LLC” can register DBAs as “Hartwell Landscaping” and “Hartwell Snow Removal,”  two brands, one entity, zero extra filings.

Limitations and Drawbacks to Consider Before Filing

A DBA has real limitations that every business owner should know before filing a DBA in Indiana:

• No liability protection, sole proprietors remain personally responsible for all debts and legal claims
• No exclusive name rights; another business can register the same name in a different Indiana county
• No trademark protection is pursued for a state or federal trademark for exclusive brand rights
• Each trade name needs its own separate filing and fee; there are no bundled registrations
• A DBA does not change your business structure, legal status, or tax obligations

Indiana DBA Name Rules and Restrictions

Indiana enforces strict naming rules. Your assumed name must comply with the following:

• Must be distinguishable from all existing registered Indiana businesses and assumed names
• Cannot include entity designators like “LLC,” “Inc.,” “Corp.,” or “LLP” if your business is not that structure
• Cannot suggest government affiliation  terms like “Federal,” “State,” “FBI,” or “Department” are not permitted
• Cannot use restricted professional titles such as “Bank,” “University,” “Engineer,” or “Attorney” without proper licensing
• Cannot be identical or confusingly similar to an existing state or federal trademark
• Cannot mislead or deceive the public in any way

Always run a full name search before submitting. A name conflict means rejection and delays.

Forms and Documents Required to File a DBA in Indiana

Business Type	Required Form	Filed With
LLC / Corporation / LLP / LP	Certificate of Assumed Business Name	Indiana Secretary of State
Sole Proprietorship / General Partnership	Assumed Business Name Registration	County Recorder’s Office

All forms require the following information:

• Legal business name
• Business address
• DBA (assumed) name
• Owner name(s) and address(es)
• Type of business activity
• Authorized signature

One important requirement to note: county-level filings must not be notarized before submission. State-level online filings through INBiz do not require this notarization.

Tax Considerations for Your Indiana DBA

Filing a DBA in Indiana does not change how your business is taxed. Here is what applies:

• A DBA carries no independent tax obligations
• Sole proprietors report DBA income on Schedule C
• LLCs and Corporations keep their existing tax filings unchanged
• No new EIN is required unless you are hiring employees or a bank requests one
• Obtaining an EIN is still recommended for privacy and professionalism

For tax situations specific to your business, consult a licensed CPA or tax professional.

Frequently Asked Questions (FAQ)

Do Indiana DBAs expire?

No. Once registered, an Indiana DBA remains valid indefinitely with no renewal requirement unless you choose to amend or cancel it.

Can I sign contracts under my DBA name?

Yes, but always include both your legal business name and your DBA name on any contract to clearly identify all parties.

Do I need a new EIN because of my DBA?

Generally no. A DBA is not a separate legal entity, so a new EIN is only required if you are hiring employees or if a bank specifically requires one.

Can multiple businesses use the same DBA name in Indiana?

Yes, in different counties. Indiana does not grant statewide exclusivity to pursue a trademark if you want exclusive name rights.

How many DBAs can I register in Indiana?

There is no limit, but each name requires its own separate application and filing fee.

Does a DBA registration protect my personal information?

No. DBA records are publicly viewable. Consider forming an LLC with a registered agent for greater privacy.

Can I file a DBA in Indiana by mail?

LLCs and Corporations must file online through INBiz. Sole Proprietors and Partnerships should check with their specific county recorder, as policies vary.

What happens if I operate without a required DBA?

You risk being unable to open a business bank account, difficulty enforcing contracts, potential fines, and increased legal liability. Register your DBA to keep your business protected and credible.
