DBA Filing in Wisconsin: Who Issues It, Cost & Steps
If you're trying to file a DBA (fictitious business name) in Wisconsin, the state is not who you file with. This is issued locally, and the rules change at the city line. Here's how to find the right counter, and what the process generally looks like once you do.
Wisconsin does not have a separate DBA filing process-you file a business entity registration instead.
Wisconsin's Department of Financial Institutions handles business entity filings, but the state does not use the 'DBA' (Doing Business As) terminology or process that many other states require. Instead, you register your business structure directly with DFI.
- The Wisconsin Department of Financial Institutions is the state agency where you file and search business entity records.

Who issues a DBA Filing in Wisconsin
This is a local permit. It is issued by your city or county, not by the state of Wisconsin. The state office listed underneath handles a related filing — it does not issue this permit.
- Wisconsin — the state business-filing office (Secretary of State in most states) (registers business entities)

Where a DBA is filed varies more than almost any other filing on this site — county clerk in many states, the state business-filing office in others.
Finding your local office
Start with the city your address sits in — the relevant department is usually called Planning, Building, Community Development, or Business Licensing. If your address is unincorporated, the county performs that role instead. Calling the main switchboard and asking who handles this is usually faster than searching.
Starting point for anything else in Wisconsin: the state business portal, https://dfi.wi.gov. It is a starting point, not the issuer of this permit.
The general US process
This sequence is the shape the process takes across the US. It is not a list of Wisconsin requirements, and no step here should be read as one — the issuing office named above sets the actual requirements.
- Step 1: Find out where a DBA is filed where you are. County clerk in many states, the state business-filing office in others, and both in a few.
- Step 2: Search that register for the name you want.
- Step 3: File the statement — often called a fictitious business name or assumed name filing — and pay the fee.
- Step 4: Publish the filing in a newspaper if that jurisdiction requires publication. Several do; most do not.
- Step 5: File the proof of publication where publication was required.
- Step 6: Use the name consistently on marketing, invoices and the bank account.
What varies: county versus state filing, whether publication is required, the fee, and whether the filing expires.
Documents usually asked for
A typical list, not a Wisconsin checklist.
- Government-issued ID
- Legal business name (if an entity, not sole prop)
- Business address
