How to File
Choose Partnership Type
Decide between a General Partnership (GP), Limited Partnership (LP), or Limited Liability Partnership (LLP). GPs require no state registration, while LPs and LLPs must file with the Wisconsin Department of Financial Institutions.
1-2 hours
Select and Verify a Partnership Name
Choose a unique business name and verify its availability using the Wisconsin DFI business name search tool. Limited Partnerships must include 'Limited Partnership' or 'LP' in the name; LLPs must include 'LLP' or 'Limited Liability Partnership'.
30 minutes
Designate a Registered Agent
Appoint a registered agent with a physical Wisconsin street address to receive legal and official correspondence on behalf of the partnership. The agent can be an individual Wisconsin resident or a registered business entity authorized to do business in Wisconsin.
30 minutes
Draft a Partnership Agreement
Create a written partnership agreement outlining each partner's roles, contributions, profit/loss sharing, decision-making authority, and dissolution procedures. While not legally required in Wisconsin, a partnership agreement is strongly recommended to prevent disputes.
2-5 hours
What's Next After Filing
Once your Partnership is officially formed, you'll want to complete these important steps:
- •File Formation Documents with Wisconsin DFI — For Limited Partnerships, file the Certificate of Limited Partnership (Form LLP-1) with the Wisconsin Department of Financial Institutions online or by mail with the $70 filing fee. General Partnerships do not need to file with the state.
- •Obtain an EIN and Open a Business Bank Account — Apply for a Federal Employer Identification Number (EIN) from the IRS at no cost, which is required for tax filing and opening a business bank account. Keeping partnership finances separate from personal finances is critical for liability and accounting purposes.
- •Register for Wisconsin Taxes and Obtain Licenses — Register with the Wisconsin Department of Revenue for applicable state taxes including sales tax and employer withholding if you have employees. Obtain any required local or industry-specific business licenses or permits through the Wisconsin One Stop Business Portal.
Advantages
- ✓Simple and inexpensive to form, especially General Partnerships which require no state registration fee
- ✓Pass-through taxation avoids double taxation — profits and losses flow directly to partners' personal tax returns
- ✓Flexible management structure with no statutory requirements for formal meetings or complex governance
- ✓Limited Partners in an LP can invest capital without personal liability for partnership debts beyond their contribution
Considerations
- •General Partners face unlimited personal liability for the debts, obligations, and legal judgments of the partnership
- •Lack of continuity — partnerships may dissolve upon the death, withdrawal, or bankruptcy of a general partner unless the agreement provides otherwise
- •Difficulty raising outside capital compared to corporations, as partnerships cannot issue stock or equity shares
