This guide combines three inputs: (1) IRS federal capital gains tax rules (Publication 17 / 550); (2) South Dakota state income tax brackets for 2026from the state's Department of Revenue and the Tax Foundation; and (3) scenario examples computed client-side using the same formulas as our crypto tax calculator. All numbers on this page reference primary public datasets listed below[1][2][3].
Refresh cadence: federal capital gains brackets and NIIT thresholds are reviewed each year after IRS annual inflation adjustments publish (typically October/November). South Dakota's state income tax brackets are reviewed annually after the legislative session closes. Page-level dateModified bumps on the next ISR refresh after an ETL run.
Known limits: scenarios assume single-filer status with standard deduction, US residency, no AMT exposure, and no local income taxes (NYC, Philadelphia, etc.). Staking and mining scenarios use ordinary-income rates at receipt and assume no subsequent appreciation between receipt and sale. For complex situations consult a tax professional or CPA.
