In the title compound, C19H27F3N2OS2, the dihedral angle between the benzene ring and dithiocarbamate group is 67.00 (9)° and a weak intramolecular N—H...S interaction generates an S(7) ring. The tert-butyl group is disordered over two orientations in a 0.628 (14):0.372 (14) ratio. In the crystal, inversion dimers linked by pairs of weak C—H...O interactions generate R22(20) loops and the aromatic rings of neighbouring pairs of molecules are involved in very weak π–π stacking interactions [centroid–centroid separation = 4.0042 (13) Å].
