Apply to the IRS for federal tax exemption (Form 1023, 1023-EZ, or 1024).
Once approved, submit your IRS Determination Letter if applying for state-level exemptions.
South Dakota has no state corporate income tax, so nonprofits are automatically exempt from state income tax.
For sales tax exemption, only limited types of organizations (such as religious, educational, or charitable institutions) may apply by contacting the South Dakota Department of Revenue.
