In the title compound, C8H11N2S+·C12H10NO3S-, the NH group of the S-benzyl-thiuronium is protonated and the inter-planar angle between the phenyl ring and the CH2 - S=C(NH2)2 unit is 47.44 (10)°. In the 4-anilinobenzene-sulfonate anion, the inter-planar angle between the two rings is 44.07 (8)°. In the crystal structure, anions are linked into chains along the c-axis direction by N - H⋯O hydrogen bonds, while additional N - H⋯O inter-actions link the cations to the anions in chains along the b-axis direction. These chains are further inter-connected into a two-dimensional network parallel to the bc plane by C - H⋯O inter-actions. C - H⋯π contacts are also observed.
