Indiana DBA Filing for Contractors

A sole proprietor named Mike Torres who starts bidding jobs as "Hoosier Builders" without filing a DBA has a problem. When the Indianapolis building department checks his business name against state records and finds nothing registered, his license application gets returned. The fix takes $25 and a trip to the county recorder — but it has to happen before the rest of the licensing process can move forward.

When Contractors Need a DBA

In Indiana, the rules depend on your business structure:

Sole proprietors and general partnerships must file an Assumed Business Name (DBA) with the county recorder's office if they operate under any name that doesn't include their full legal surname. If Mike Torres operates as "Mike Torres Construction," no DBA is needed. If he operates as "Torres Home Improvement" or "Hoosier Builders," he needs a filing.

LLCs and corporations file their DBA with the Indiana Secretary of State through the INBiz portal instead of the county recorder. The online filing fee is $20; paper filings cost $30. This is less common for LLCs since most contractors choose their trade name as their LLC name when they file Articles of Organization.

There's a statutory exemption: individuals operating a sole proprietorship under a name that includes their true legal surname don't need an Assumed Business Name registration under IC 23-0.5-3-4.

The County Recorder Filing Process

For sole proprietors and partnerships, the DBA process is straightforward:

1. Visit the county recorder's office in the county where your business originates
2. Complete the Certificate of Assumed Business Name form
3. Pay the $25 recording fee
4. Receive a recorded copy as proof of filing

The county-level filing goes to the recorder in the county where the business originates. If you also work elsewhere, confirm with the relevant recorder whether a separate filing is required; do not assume a second filing is necessary.

After recording, check with the county recorder about any renewal, amendment, or withdrawal requirements, and keep the recorded name aligned with the trade name on your insurance certificates, surety bonds, and local license applications.

Name Matching and Why It Matters

Indiana's local building departments enforce strict name-matching rules. Every document in your licensing packet must display the same business name:

• State registration (LLC filing or DBA recording)
• Surety bond
• Certificate of insurance
• Workers' compensation policy or WCE-1 exemption
• Local contractor license application

For sole proprietors with a DBA, the correct display format on all documents is: "[Your Legal Name] DBA [Trade Name]" — for example, "Michael Torres DBA Torres Home Improvement."

Using just the trade name without the legal name, or just the legal name without the DBA, creates a mismatch. Indianapolis BNS clerks catch these mismatches routinely and return the entire application packet.

DBA vs. LLC: Which Is Better for Contractors?

A DBA gives you a trade name but no liability protection. Your personal assets remain fully exposed to business debts and jobsite claims.

An LLC filed through INBiz ($95 online) gives you both a trade name and a legal barrier between your personal and business assets. For contractors working on other people's property with power tools and heavy materials, that separation matters.

If you already have an LLC and want to operate under a different trade name, you can file an Assumed Business Name for the LLC through INBiz for $20. But most contractors simplify things by choosing their preferred trade name as their LLC name from the start.
