South Dakota
South Dakota has a constitutional supermajority requirement to raise taxes under Article XI Section 13-14 of the South Dakota Constitution. This was first enacted in 1978 by legislative referendum and then amended by voter approval in 1996 to apply to new taxes. The current version requires a 2/3 supermajority vote in the legislature or by a public vote to raise tax rates on existing taxes or for the legislature to create new taxes.
