Relevant Laws
South Dakota Uniform Partnership Act (SDCL Chapter 48-7A)
This is the primary law governing partnerships in South Dakota. It defines what constitutes a partnership, the rights and duties of partners, and how partnerships are formed and dissolved. Understanding this act is essential when setting up a partnership as it establishes the legal framework for your business relationship.
Partnership Filing Requirements (SDCL 48-7A-1001)
While South Dakota doesn't require formal registration for general partnerships, this section outlines the statement of partnership authority that can be filed with the Secretary of State. Filing this statement can help establish the authority of partners to enter into transactions on behalf of the partnership and provides public notice of the partnership's existence.
Partner's Liability (SDCL 48-7A-306)
This statute addresses the joint and several liability of partners for partnership obligations. In South Dakota, partners are personally liable for the debts and obligations of the partnership, which is a crucial consideration when choosing this business structure over others with liability protection.
Partnership Property (SDCL 48-7A-203 to 48-7A-204)
These provisions govern how property is acquired and held by the partnership. Understanding these laws is important when determining what assets belong to the partnership versus individual partners, and how property rights are handled within the partnership structure.
Partner's Rights and Duties (SDCL 48-7A-401 to 48-7A-404)
These sections outline the rights and responsibilities of partners, including management rights, profit sharing, and fiduciary duties. These provisions are particularly relevant when drafting a partnership agreement, as they establish default rules that apply unless partners agree otherwise.
South Dakota Tax Laws for Partnerships (SDCL Chapter 10-43)
South Dakota doesn't have a state income tax, but partnerships still have tax obligations. This chapter covers tax requirements for partnerships operating in South Dakota, including how partnerships are treated for tax purposes at the state level.
Business Name Registration (SDCL 37-11)
If your partnership will operate under a name other than the surnames of the partners, this law requires you to register a fictitious business name (also called a DBA or 'doing business as') with the Register of Deeds in each county where you conduct business.
