In the title compound, NH4+·(C2H5O)2PS2−, the ammonium cation is connected by four charge-assisted N—H⋯S hydrogen bonds to four tetra­hedral O,O′-diethyl dithio­phosphate anions, forming layers parallel to (100). The polar and non-polar constituents of the layers are stacked alternately along [100]. Inter­lacing of the external ethyl groups through van der Waals inter­actions combines these layers into a three-dimensional structure.
