The state's Small Business Development Center (SBDC) network offers no-cost advising, and volunteer mentors through SCORE chapters have built businesses like yours. The Secretary of State and state commerce resources publish plain guides on formation, licensing, and taxes, so lean on them before you ever pay a middleman.

South Dakota, specifically.

South Dakota is Mount Rushmore, the Badlands, and the roar of the Sturgis rally, plus a quiet reputation as a banking and trust haven. Sioux Falls is booming and affordable. With no state income tax and a welcoming spirit, it is an underrated place to start something and keep more of what you earn.

The six steps, in order

1. 1

   Pick your business structure

   Most first businesses in South Dakota choose an LLC for the liability separation between the business and your personal life. Sole proprietorships are simpler but offer no separation; corporations fit businesses raising investment.

2. 2

   Check that your business name is free

   Search the South Dakota Secretary of State's business registry to confirm nobody in South Dakota already holds the name, and check the matching web domain at the same time. Our free name generator checks the domain with every name it suggests.

3. 3

   File your formation documents with the South Dakota Secretary of State

   This is the official step that makes the business real. File directly on the state's own site and pay only South Dakota's filing fee. Every state requires a registered agent with a physical address in the state; if you live in South Dakota, you can usually be your own.

4. 4

   Get your EIN free from the IRS

   The Employer Identification Number is the business's tax ID. The IRS issues it directly at irs.gov in about five minutes, at no charge. Never pay anyone for an EIN alone. Get the EIN at irs.gov ↗

5. 5

   Check for licenses and permits

   Many businesses also need a city or county business license, and some industries need South Dakota state licenses. The South Dakota Secretary of State's site and your city hall list what applies.

6. 6

   Open the business bank account and connect payments

   Keep business money separate from day one: it protects the legal separation your LLC exists for and keeps taxes clean. Bring your EIN and formation documents to the bank. Our free Get Paid directory lists business banks and payment processors in the order to set them up.
