Per diem rates for official travel in South Dakota are set by the U.S. General Services Administration (GSA). These federal rates are mandatory for federal employees and serve as a common benchmark for private sector companies looking to create an IRS-compliant reimbursement policy.
For Fiscal Year 2025 (October 1, 2024, to September 30, 2025), key rates are broken down as follows:
