Business Entity Formation

The Wisconsin DFI registers a broad range of business entities. Among these are Business Corporations, Limited Partnerships, Limited Liability Companies, General Partnerships (optional registration), and Foreign entities licensed to transact in Wisconsin. Interestingly, Veterans organizations and certain types of religious corporations also fall within their purview.

Notably, sole proprietorships have the option to register their business name by filing a Tradename registration. However, one question that commonly arises is how to verify name availability. This is handled through the Corporate Registration Information System (CRIS). Keep in mind, however, that names should not be assumed available until written confirmation from the department is obtained.

A critical factor in the formation process is deciding whether legal assistance is necessary. Although this is not mandatory, having an attorney's professional guidance can significantly ease the process of making vital decisions such as entity type selection.

Role of a Registered Agent

An important position that often raises questions is that of the Registered Agent. This is a Wisconsin-resident individual or entity appointed to receive official communications on behalf of the business. The physical address of the registered agent's business office serves as the corporation's "registered office." It is crucial to maintain updated registered agent information to avoid potential consequences of missed communications.

Document Submission Process

When it comes to document submission, the DFI offers online and paper-based options. However, queries often arise about emailing documents to the DFI. The DFI has set guidelines for email submissions, such as ensuring attachments are in .pdf format and receipt of payment is confirmed.

For those needing faster processing, an expedited service is available for an additional fee. Importantly, for anyone needing to correct a mistake on a submitted form, a Statement of Correction form should be filed.

Additional Services and Miscellaneous Queries

Beyond the routine queries related to business entity formation and document submission, the DFI offers additional services. These include providing certified or simple copies of any filed documents and a Corporation Master File available for purchase. However, it's worth noting that ownership details are not disclosed by the department, as business entities are not required to provide this information.

For individuals interested in acquiring a Seller's Permit or qualifying as a Qualified New Business Venture, it's important to consult the Department of Revenue and follow the relevant instructions.

Understanding Annual Reporting Requirements

An annual report is a crucial document that certain entity types are required to submit. The deadlines for these reports are based on the incorporation or qualification date of the entity. Neglecting this annual reporting requirement can lead to the business entity being labeled "delinquent," which, if not rectified, could lead to administrative dissolution.

Contact Information

Lastly, the DFI has provided contact details for further inquiries. They can be reached via phone at (608) 261-7577 or by email at DFICorporations@dfi.wisconsin.gov. Both their physical and mailing addresses have been provided for those who may need to contact them through these channels.
