In the title compound, C10H11NO3S, the benzisothia­zole ring system is almost planar [maximum deviation = 0.030 (1) Å for the S atom]. The isoprop­oxy group is almost in the plane of the benzisothia­zole ring system [N—C—O—C = 4.5 (2)°] with one of its methyl groups in an anti­periplanar orientation relative to the benzisothia­zole ring system [C—C—O—C = −162.0 (2)°].
