Introduction: South Dakota's Best-Kept Secret
South Dakota is a hidden gem for nonprofit formation.

No Publication Requirement

Bylaws should address:

Board Meetings
Annual Meeting: Required by state law Additional Meetings: As determined by bylaws Remote Participation: Permitted if allowed by bylaws and authorized by state statute Minutes: Should be maintained per best practices
State Tax Exemption: South Dakota's Greatest Advantage
Income Tax
South Dakota has no state income tax and no corporate income tax. This means:
- No state income tax exemption application needed
- No annual state tax return filing required
- Automatic zero state tax liability for all nonprofits (whether 501(c)(3) or not)
This is a massive advantage: you don't have to choose between state and federal compliance at the income tax level.
Sales Tax Exemption
Sales tax exemption is available for nonprofits with 501(c)(3) status.
Requirements:
- Must be organized and operated for charitable, educational, or religious purposes

- Must apply separately to South Dakota Department of Revenue
Application Process:
- File Sales Tax Exempt Status Application with South Dakota Department of Revenue

- Once approved, organizations receive exemption certificate to provide to vendors
Special Exemptions:
- Membership organizations (YMCA, Boy Scouts, Lions Club, etc.) receive special exemptions on membership fee revenue
- Religious organizations and schools receive additional exemptions
Renewal: Relief agencies and private schools must renew sales tax exemption every 5 years
Property Tax Exemption
Property tax exemption is available for property owned and used by nonprofits for charitable, educational, or religious purposes.

- Form 990: Gross receipts over $200,000
Charitable Solicitation Registration
South Dakota's Advantage: Most nonprofits do NOT need to register for charitable solicitation at the state level.
Exception: Only if you hire PAID PROFESSIONAL SOLICITORS for telephone solicitation campaigns must you register.
Paid Solicitor Registration (if applicable):
- File with South Dakota Attorney General, Division of Consumer Protection
- Must file 30 days BEFORE conducting any solicitation
- Requires surety bond ($10,000 or $20,000 depending on whether solicitor handles funds)
- Organizations conducting direct mail or using employees don't need to register
Key Deadlines: Simple and Clear
| Task | Timeline | Deadline | |------|----------|----------| | File Articles of Incorporation | Immediate | As soon as ready | | Organizational Meeting | Within 30 days | Before operations begin | | Obtain Federal EIN | After incorporation | Within 30 days | | Apply for 501(c)(3) Status | ASAP | Within 27 months of incorporation | | File First Annual Report | In anniversary month year after incorporation | First day of anniversary month | | Annual Report (every year) | Annually | First day of anniversary month | | Federal Form 990 | Annually | May 15 (for calendar-year orgs) | | Sales Tax Exemption Application | After IRS approval | No firm state deadline |
Important Considerations: Watch These
Anniversary Month is Critical: Your annual report is due on the first day of your incorporation anniversary month, with no grace period. Miss this deadline and you risk penalties and dissolution. Set a reminder now for annual reporting.
Three-Director Minimum: While state law technically allows one director, the IRS requires three for 501(c)(3) status. Start with three from day one.
Federal 501(c)(3) is Essential: While South Dakota gives automatic income tax exemption regardless of federal status, federal 501(c)(3) status unlocks donation deductibility, grants eligibility, and other federal benefits. Apply within 27 months of incorporation to preserve retroactive exemption eligibility.
No State Tax Return: Unlike most states, you don't file a state tax return in South Dakota. This simplifies annual compliance significantly. Focus on federal Form 990 and state annual report only.
Paid Solicitor Exception: If you ever hire paid professional solicitors (not employees), you must register with the Attorney General. Monitor this requirement as your organization grows.
