In the title compound, C 21 H 17 NO 4 S, all bond lengths and angles show normal values. The sulfonyl-bound phenyl ring forms a dihedral angle of 88.31 (1) with the mean plane of the carbazole fragment. The crystal packing is stabilized by weak intermolecular -, C-HÁ Á Á and C-HÁ Á ÁO interactions.
