In the title compound, C12H13NO3S, a saccharin derivative, the dihedral angle between the aromatic and isothia­zole rings is 2.91 (12)°. The planar 3,3-dimethyl­allyl group [maximum deviation = 0.0086 (16) Å] is oriented at dihedral angles of 71.86 (7) and 74.35 (7)° with respect to the aromatic and isothia­zole rings, respectively. In the crystal structure, weak inter­molecular C—H⋯O inter­actions link the mol­ecules into chains along the c axis. A weak C—H⋯π inter­action is also present.
