In the title compound, C16H17NO3S2, the dihedral angles between the O/C/C/S group and the 2H-chromene ring system and the thiocarbamate group are 14.46 (9) and 83.30 (9)°, respectively. The bond-angle sum at the N atom is 360.0°. One of the methyl C atoms lies above the thiocarbamate plane and one lies below it [deviations = 1.264 (3) and -1.147 (3) Å, respectively]. In the crystal, inversion dimers linked by pairs of C-HO hydrogen bonds generate R22(10) loops. Weak aromatic - stacking interactions [shortest centroid-centroid distance = 3.8138 (11) Å] are also observed.
