What Is a Foreign Qualification?
A foreign qualification enables your limited liability company to do business in the state of South Dakota. It doesn’t matter which state you originally formed your business in ― or in other words, the state your domestic LLC is located in ― as the qualification process to register a foreign LLC in South Dakota is the same regardless of where your domestic LLC is based.
The confusion surrounding foreign qualification usually centers on what it means to “do business” in a state outside of your primary state. This gets especially problematic considering some states don’t strictly define what it means to transact business in that state. South Dakota state law does not define “doing business” in the state.

This means that individuals and businesses could fail to honor contracts with your business, and you wouldn’t be able to do anything about it legally.
Should I Hire a Business Service Provider to File My South Dakota Foreign Qualification?
If you don’t want to handle your foreign qualification on your own, you have options. Some entrepreneurs choose to hire a lawyer to prepare and file their Certificate of Authority, which can be a good option if you’re concerned about getting the job done right. However, attorney’s fees can be quite expensive.
The other option is to hire a business service provider like Incfile or ZenBusiness to register your foreign LLC with the state of South Dakota.
These companies can typically get your foreign qualification done for a fraction of the price of an attorney. This is our preferred route if you don’t want to go with the DIY option.
