Operating Under an Assumed Name in Indiana
Complete guide to registering and maintaining an assumed business name in Indiana.
Understanding Assumed Business Names in Indiana
An assumed business name, commonly referred to as a DBA (doing business as), serves as an alternative name under which a business operates. In Indiana, understanding the distinction between different business structures is essential, as filing requirements vary significantly depending on your business entity type. Whether you operate as a sole proprietor, partnership, limited liability company, or corporation, Indiana state law mandates specific registration procedures to legally conduct business under an assumed name.
The primary purpose of registering an assumed business name is to establish a clear public record of the connection between your business operations and your legal entity. This protects consumers by ensuring transparency and helps prevent fraudulent business practices. However, it’s important to note that registering an assumed business name does not automatically grant trademark protection or prevent other businesses from using similar names in different jurisdictions.
Determining Your Business Classification
Before beginning the registration process, you must first identify your business structure, as this determines where and how you file your assumed business name documentation. Indiana recognizes several primary business classifications, each with distinct regulatory requirements.
Unincorporated businesses include sole proprietorships and general partnerships. A sole proprietorship is a business owned and operated by a single individual without formal organizational structure. General partnerships involve two or more individuals sharing ownership and management responsibilities. These business types follow one filing pathway in Indiana.
Incorporated entities encompass limited liability companies (LLCs), corporations, professional corporations, limited partnerships, limited liability partnerships, and foreign business entities registered in Indiana. These formally organized business structures follow a different, state-level filing procedure.

Registration Requirements by Business Type
Unincorporated Businesses: County-Level Filing
If you operate as a sole proprietor or general partnership, your assumed business name registration occurs at the county level rather than the state level. Specifically, you must file a Certificate of Assumed Business Name with the recorder’s office in each county where your business conducts operations or maintains a physical location.
An important exception exists for businesses whose operating name already includes the true surnames of all owners. For example, if John Smith operates a sole proprietorship under the name ‘Smith’s Plumbing Services,’ no assumed name registration is required because the owner’s surname is part of the business name. However, if the same proprietor wanted to operate under ‘Quick Plumbing Services,’ registration would be mandatory.
The multi-county requirement deserves particular attention. If your business operates in multiple counties—whether through satellite locations, service territories, or branch offices—you must file separate certificates in each applicable county. This ensures comprehensive public notice in all jurisdictions where you conduct business activities.
Incorporated Entities: State-Level Filing
Limited liability companies, corporations, and other formally registered business entities must file their assumed business name documentation with the Indiana Secretary of State. This centralized filing system applies regardless of how many counties your business operates within. You file once at the state level, and that registration applies throughout Indiana.
Incorporated entities that operate under their registered legal name need not file an assumed business name certificate. For instance, if your LLC is registered as ‘Digital Solutions LLC’ and you operate entirely under that name, no additional filing is necessary. However, if you want to conduct business under any other name, state-level registration becomes mandatory.
The Registration Process: Step-by-Step
Conducting a Name Availability Search
Before investing time and resources into filing, you should verify that your desired assumed business name is available. The Indiana Secretary of State website maintains searchable databases of registered assumed business names. Conducting this preliminary search prevents the frustration of completing paperwork only to discover your chosen name is already in use.
For sole proprietors and partnerships filing at the county level, you should also search the specific county recorder’s assumed name records. Some counties maintain their own searchable databases, while others require direct contact with the recorder’s office. This dual-search approach ensures comprehensive verification of name availability.
Availability searches typically reveal active assumed business names registered within the past several years. Note that availability in one county does not guarantee availability in another county, which is why multi-county searches are essential for businesses with multiple locations.
Completing the Certificate of Assumed Business Name
Indiana requires completion of the Certificate of Assumed Business Name form, also known as Form 30353. This standardized document collects essential business information and creates the official record of your assumed business name registration.
The form requires several key pieces of information:
- Your legal business entity name (the registered name under which your business was formed)
- Your complete business address
- The assumed business name you wish to register
- Your legal name and address as the business owner or authorized representative
- The date your business was established or formed
- Signature authorization from an owner or authorized officer
Accuracy is critical when completing this form. Errors or omissions can result in processing delays or rejection of your application. If you’re uncertain about any field, contact your county recorder (for county-level filings) or the Indiana Secretary of State (for state-level filings) before submission.
Notarization Requirements
If you submit your Certificate of Assumed Business Name by mail to the Indiana Secretary of State, the document must be notarized by a qualified notary public. The notary verifies the identity of the signing party and confirms that the signature is genuine. This requirement applies specifically to mail-in submissions to the state level.
County-level filings may have different notarization requirements depending on the specific county recorder’s office. Some counties require notarization for mail-in submissions, while others do not. Contacting your county recorder in advance clarifies these requirements and prevents submission delays.
Online filings through the state’s INBiz portal typically do not require separate notarization, as the online system includes built-in verification mechanisms.
Filing Methods and Submission Options
Online Filing Through INBiz
The Indiana Secretary of State provides an online filing system called INBiz, which streamlines the assumed business name registration process. This system allows incorporated entities to submit their Certificate of Assumed Business Name electronically, typically with faster processing times compared to paper submissions.
To file online, you create an INBiz account, navigate to the assumed name filing section, and follow the system prompts. Online filing eliminates the notarization requirement and provides immediate confirmation of submission. Processing typically takes several business days for online filings.
Mail Submission
For those who prefer traditional mail submission, you can print the completed Certificate of Assumed Business Name form and send it to the appropriate office. State-level submissions go to the Indiana Secretary of State, while county-level submissions go to the specific county recorder’s office.
Mail submissions require notarization (for state-level filings) and typically take longer to process—sometimes several weeks depending on office workload. You should include clear instructions with your submission and consider using certified mail to confirm delivery.
In-Person Filing
Both county recorders and the Indiana Secretary of State accept in-person submissions. This method provides the advantage of immediate submission and the opportunity to ask questions before finalizing your filing. In-person filing at the county level is often the fastest option and allows you to address any discrepancies immediately.
Filing Fees and Associated Costs
Indiana imposes modest filing fees for assumed business name registration, making it an affordable step in establishing your business operation.
| Filing Method | Fee Amount | Applicable To |
|---|---|---|
| Online Filing | $21 | State-level filings (incorporated entities) |
| Mail or In-Person Filing | $30 | State-level filings (incorporated entities) |
| County-Level Filing | Varies by county | Sole proprietors and partnerships |
County-level filing fees vary depending on your specific county’s fee schedule. Some counties charge minimal fees of $10-15, while others may charge higher amounts. Contacting your county recorder provides exact fee information for your jurisdiction.
Beyond official filing fees, you may choose to use professional filing services that handle the paperwork, form completion, and submission on your behalf. These services typically charge between $75-150 in addition to official state and county fees, but save time and reduce the likelihood of filing errors.
Tax Implications of Assumed Business Names
A common misconception is that registering an assumed business name changes your tax structure or creates new tax obligations. This is not the case. Registering an assumed business name is purely an administrative and legal filing—it does not affect how your business is taxed by federal, state, or local authorities.
A sole proprietor operating under an assumed business name still reports business income on their personal tax return (Form 1040 with Schedule C). The business income is taxed at individual rates regardless of the assumed name used. Similarly, an LLC taxed as a partnership continues with partnership taxation, and a corporation retains its corporate tax status.
The only instance where assumed business names have tax implications is when they’re used to establish a formal business entity (such as incorporating as an LLC), which is a separate process from assumed business name registration. Registering the assumed name itself triggers no tax changes.
Timeline and Processing Expectations
Processing times for assumed business name filings in Indiana vary based on your submission method and filing location. Online submissions through INBiz typically process within 5-10 business days. Mail submissions may take 2-4 weeks depending on workload and whether the submission is complete and properly notarized.
County-level filings often process more quickly than state-level filings, sometimes within 1-2 weeks for in-person submissions. However, processing times vary significantly by county, so contacting your specific county recorder provides accurate expectations.
Once approved, your assumed business name registration becomes immediately effective. You can legally operate under that name upon approval notification. Keep your approval documentation for your records and provide copies to financial institutions, vendors, and licensing agencies as needed.
Maintaining Your Registration and Renewal Considerations
Indiana does not require renewal of assumed business name registrations. Unlike some states that require periodic re-filing every 5-10 years, Indiana assumed business names remain in effect indefinitely once registered, provided you continue operating under that name.
However, if you cease operations under an assumed business name or permanently change your business name, you should file a Cancellation of Assumed Business Name or Dissolution of Doing Business As form to clear the public record. This prevents confusion and ensures accurate business registration records.
If your business relocates to a different county, you may need to file in the new county and potentially cancel the registration in the old county, depending on whether you maintain any presence there. Consulting your county recorder clarifies relocation procedures.
Important Considerations and Common Pitfalls
Name registration does not equal trademark protection. Registering an assumed business name protects against other businesses using identical names within Indiana, but does not prevent use in other states or provide federal trademark protection. Consider federal trademark registration if your business operates nationally or online.
File in all applicable jurisdictions. Sole proprietors and partnerships operating in multiple counties must file in each county where they do business. Filing in only one county leaves other operating areas without proper legal coverage.
Ensure accurate and complete information. Errors in your Certificate of Assumed Business Name can result in processing delays or rejection. Double-check all names, addresses, and dates before submission.
Distinguish between assumed names and legal entity formation. Registering an assumed business name is not the same as forming an LLC or corporation. If you want to establish a formal business entity, that requires a separate filing process.
Frequently Asked Questions
Q: Can I use an assumed business name before filing with the state or county?
A: No, you cannot legally use an assumed business name in Indiana until you have completed the registration process and received approval. Operating under an unregistered assumed name violates state law.
Q: If I register an assumed business name, do I need to register my business as an LLC?
A: No, assumed business name registration and LLC formation are separate processes. You can operate as a sole proprietor or partnership with a registered assumed business name without forming an LLC. However, forming an LLC provides liability protection that assumed business name registration does not offer.
Q: How long does it take to get approval for an assumed business name in Indiana?
A: Processing times vary. Online submissions through INBiz typically take 5-10 business days. County-level in-person filings may process within 1-2 weeks. Mail submissions can take 2-4 weeks.
Q: Can I register multiple assumed business names for the same business?
A: Yes, a single business can register multiple assumed business names by filing separate certificates for each name. Each name requires a separate filing and associated fees.
Q: What happens if someone else registers the assumed business name I want to use?
A: If your desired name is already registered, you cannot use it. You must choose a different assumed business name. This is why checking availability before filing is important.
Q: Do I need to renew my assumed business name registration?
A: No, Indiana does not require renewal of assumed business name registrations. Once filed and approved, the registration remains in effect indefinitely as long as you continue operating under that name.
Q: Can I transfer my assumed business name to someone else?
A: Assumed business names are tied to specific business entities and owners. Transferring ownership of a business typically requires canceling the old registration and filing a new one under the new owner’s information.
