Indiana Assumed Name Certificate: How to File a DBA
An Indiana assumed name certificate lets a business operate under a name different from its legal name. Often called a DBA (“doing business as”), trade name, or fictitious name, it can help a company present a distinct name to customers while keeping its existing legal structure. The filing process depends on whether the business is a registered entity, such as an LLC or corporation, or an individual or partnership. Knowing where to file—and what the certificate does not do—can help prevent delays and naming mistakes.
What Is an Indiana Assumed Name?
An assumed name is a name a person or business uses to conduct business that differs from the name under which it is legally organized or identified. For example, a company registered as “Hoosier Home Services LLC” might advertise as “Hoosier Heating.” The second name is an assumed name if it is used in business instead of the LLC’s legal name.
In Indiana, “assumed name” is the term commonly used in state business filings. “DBA” is a familiar, informal label, but it does not create a separate type of business or legal entity. Filing a certificate generally records the relationship between the business and the name it uses; it does not create a new company.
The filing requirement and filing office depend on the business’s legal form. Indiana’s business-entity rules provide for assumed-name filings by entities registered with the state, while individuals and certain unregistered businesses generally deal with the county recorder. Businesses should verify the applicable procedure before submitting a filing because the correct office depends on the facts of the business.
Where to File an Indiana Assumed Name Certificate
| Business type | Typical filing office | Key consideration |
|---|---|---|
| Indiana LLC, corporation, limited partnership, or other registered entity | Indiana Secretary of State, Business Services Division | File the assumed-name document for the existing entity; do not form a second entity unless that is intended. |
| Sole proprietor or certain general partnerships | County recorder in the county where the business has its principal place of business | Check the recorder’s instructions and any local requirements before filing. |
| Business operating in more than one county or with an out-of-state registration | Depends on legal form and circumstances | Confirm state and county filing obligations with the relevant offices. |
Registered entities can look up filing options through the [Indiana Secretary of State’s Business Services Division](https://www.in.gov/sos/business/). County-level filers should contact the recorder for the county where the business is principally located. A county recorder can confirm local forms, submission methods, fees, and whether additional copies or notarization are required.
Some businesses have more than one relevant filing obligation. For example, registering an assumed name with the state does not necessarily satisfy tax, licensing, or local permitting requirements. A business with locations or operations in multiple jurisdictions should check with each appropriate government office.
How to File an Assumed Name for an Indiana Business Entity
Confirm the entity’s legal name and status
Start by checking the company’s exact legal name and current registration in the Indiana Secretary of State’s business records. Use the spelling and entity ending shown in the official record, such as “LLC” or “Inc.” A mismatch can cause a filing to be rejected or make it harder to connect the assumed name to the correct entity.
Choose and check the assumed name
Search Indiana’s business database for similar names before filing. A database search is a useful preliminary check, but it is not a guarantee that a name is legally available for every purpose or that it does not infringe another party’s trademark. Businesses should also consider searches of federal trademark records, domain names, and relevant industry sources when the name is important to branding.
Indiana’s assumed-name filing is not the same as reserving a name or registering a trademark. It does not automatically give the filer exclusive rights against every other business using similar wording. A name may also be subject to restrictions under laws governing regulated professions, financial services, or other industries.
Complete the state filing
Use the Secretary of State’s current filing system or form for an assumed name associated with an existing business entity. The filing generally identifies the entity, its state identification or registration information, and the assumed name. Follow the current instructions carefully, including requirements for an authorized signer and any filing-fee payment.
Online availability, forms, processing times, and fees can change. The Secretary of State’s website is the authoritative source for current requirements. Before mailing a paper filing or paying a third-party service, confirm that the form is current and that the fee is paid to the correct office.
Save proof of filing
After submission, keep the confirmation, receipt, and accepted filing record with the company’s organizational documents. The business may need proof for a bank, payment processor, landlord, supplier, licensing agency, or customer. If the filing is rejected, review the stated reason, correct the information, and resubmit as directed.
How Sole Proprietors and Partnerships File
A sole proprietor does not create a separate legal entity simply by starting a business. When the proprietor uses a name other than the proprietor’s legal name, an assumed-name filing may be required with the county recorder. The same county-level process may apply to certain partnerships that are not registered as a state business entity.
County procedures are not necessarily identical. Before filing, contact the recorder’s office to ask which certificate or form is required, whether the owner or partners must sign, whether signatures must be notarized, and how the filing can be submitted. Ask about the fee and whether certified copies are available if a bank or agency requests one.
Partnership arrangements can raise questions about who owns the business, who is authorized to sign, and whether a state-registered entity is involved. If the business has an LLC or corporation as an owner, or if it has registered with the Secretary of State, the entity’s status may affect where the assumed-name filing belongs. When the structure is unclear, confirm the correct route with the relevant government office or a qualified professional.
Information to Gather Before Filing
Requirements vary by filing office and business structure, but preparing common information can make the process smoother. A filer may need:
- The business’s exact legal name and entity type, if it is registered.
- The proposed assumed name, written consistently with the name the business intends to use.
- The principal business address and, where requested, the county of the principal place of business.
- State registration details, such as an entity identification number, for a registered business.
- Authorized signer information, including the signer’s title or relationship to the business.
- Payment and supporting documents required by the filing office.
Use a business address that complies with the form’s instructions. A mailing address, registered-agent address, and principal office address serve different purposes and should not be substituted for one another without checking the requirements.
What an Assumed Name Certificate Does—and Does Not Do
An Indiana assumed name certificate provides a public record that a business uses a name other than its legal name. It can help connect contracts, marketing, invoices, and customer-facing activity to the existing owner or entity. It may also be requested during business banking or vendor onboarding.
However, the filing does not:
- Create an LLC, corporation, partnership, or other separate legal entity.
- Provide limited liability protection to a sole proprietor or general partner.
- Automatically register the name as a state or federal trademark.
- Replace tax registrations, employer accounts, professional licenses, or local permits.
- Change the business’s legal name in its formation documents.
A sole proprietor who wants liability protection may need to consider forming an entity, such as an LLC, and maintaining it according to Indiana law. An assumed name alone does not separate personal and business liabilities. Entity formation and ongoing compliance are distinct from assumed-name registration.
Fees, Processing, and Renewals
Filing fees and processing times depend on the filing office, filing method, and current state or county schedule. Because fees can change, the Secretary of State’s fee schedule and the relevant county recorder’s website or office should be checked immediately before filing. Avoid relying on old articles or commercial websites for current prices.
Do not assume that an assumed-name filing lasts forever or that it must be renewed on the same schedule as an annual business report. Check the filing record and current instructions for expiration, amendment, cancellation, or renewal requirements. A change in the business’s legal name, ownership, address, or use of the assumed name may call for an update or a new filing.
Common Filing Mistakes to Avoid
- Filing with the wrong office: A registered LLC generally follows state business-entity procedures, while a sole proprietor may need to contact the county recorder.
- Using an assumed name as if it were a legal entity: Contracts and tax documents should identify the actual owner or entity as required, not just the brand name.
- Assuming a name search guarantees exclusive rights: State business records and trademark rights are different systems.
- Entering inconsistent information: Spelling, entity endings, addresses, and identification details should match official records.
- Skipping related registrations: A DBA filing does not substitute for tax, licensing, zoning, or employer registrations.
- Ignoring changes: Businesses should check whether a change of ownership or discontinuation requires an amendment or cancellation.
After the Certificate Is Filed
Once the filing is accepted, use the assumed name consistently in advertising, invoices, websites, and customer communications. Where legal or financial documents require the underlying legal owner, identify both the owner and the assumed name—for example, “Example Services LLC, doing business as Hoosier Heating.” The exact wording may depend on the document and the business’s legal structure.
Ask the bank, payment processor, and major vendors what documentation they require to associate the assumed name with the business account. Keep the filed certificate and acceptance confirmation available, and make sure the name used for customer payments matches the records held by financial institutions.
Businesses should also review tax and licensing obligations. Indiana tax registration is handled separately from an assumed-name filing, and city or county rules may apply to business locations, signage, construction, food service, or regulated work. The [Indiana Department of Revenue](https://www.in.gov/dor/) and relevant local agencies can provide information about their own requirements.
Where to Verify Indiana Filing Requirements
For a registered business entity, consult the [Indiana Secretary of State’s Business Services Division](https://www.in.gov/sos/business/) for current forms, online filing options, fees, and entity records. For a sole proprietor or partnership filing at the county level, contact the county recorder directly. For tax, licensing, or legal questions, use the appropriate government agency or seek advice from a qualified attorney or tax professional.
Because filing rules and administrative procedures can change, official state and county guidance should take priority over general summaries. Confirming the business structure and the correct filing office before submitting an Indiana assumed name certificate is the most effective way to avoid unnecessary delays.
