Guidelines to Follow in Naming LLC

  •  Use a business name with the abbreviation “LLC” or the phrase “Limited Liability Company.” 
  • Your decided business name must not coincide with any existing government entity. Otherwise, you might have to face legal lawsuits when filing your LLC.
  • Use the LLC name availability checker to ensure your business name is unique.
  • Get a license first if you plan on using restricted words to avoid any complications.

Note that you must put adequate effort into naming your LLC because this name will be with your business for a long time. Making your LLC name unique is vital as it would prevent people from confusing your business with others, not to mention it would be easier for them to recall your business, products, or services.

How Do I Reserve an LLC Name in South Dakota

To reserve an LLC name in South Dakota you need to submit a name reservation request form to the South Dakota Secretary of State by mail or online by paying a filing fee of $25.

Fortunately, there are several ways to reserve an LLC name in South Dakota. You can do this online or by mail. However, you should be aware of the rules that govern name reservations. It’s also important to make sure that your LLC name meets all the state’s requirements. Using a name that is too similar to an existing business can cause the Secretary of State to reject your application.

You can find out if your business name is available for reservation in the South Dakota SOS database. The database is managed by the Secretary of State and contains a listing of all available business names in the state. You can search for a name by entering your proposed business name and business address in the database. In addition, you can also search for names that are already registered in South Dakota. If you’re lucky, you may be able to get a name that is not currently registered.

You can also search for a name by using the search function of the South Dakota SOS website. It’s pretty easy to do and will tell you if your name is available.

The process is relatively simple and only takes a few minutes.

Aside from a business name, you may also want to consider registering for an Employer Identification Number. This is similar to a Social Security number, but it’s specifically used for opening a business bank account. The number is also important for filing federal taxes. Aside from saving you from sharing your personal social security number with your employees, the number can also be used to apply for federal loans. It’s also the best way to make sure that you’re paying the least amount of federal taxes possible.

You can also check out the South Dakota Governor’s Office of Economic Development. This website offers a state comparison and a wage calculator. It also has an online business name search function.
