4. Do I Need a South Dakota State Tax ID Number?

You may wonder whether you need a South Dakota state tax ID number, especially if you aren’t sure whether you need a federal tax ID number.

To start, let’s clear up the terminology. In many cases, the general term "tax ID" refers to your federal tax ID number. This is also frequently called an employer identification number, or EIN. This is a 9-digit, unique identifying number that’s assigned to your business upon registering with the federal government. You’ll need one of these if you’re going to hire any employees, or if your business is owned by more than one person. You’ll also need one to open a bank account, apply for a business loan, or obtain other financial products for your business. If you’re going to apply for a business license or permit, a federal tax ID number is also typically required.

Your South Dakota state tax ID number is also a unique, identifying number, but it applies at the state level, and is assigned to your business when registering with the state government of South Dakota. You’ll need one if you’re hiring employees in the state of South Dakota, if you’re selling taxable goods and services in the state, or if you’re going to owe excise taxes on some types of regulated goods.
