In the crystal of the title compound, C6H6Cl2N+·C6H4ClO3S-, the 2,5-dichloroanilinium cations and 4-chlorobenzenesulfonate anions are located on a crystallographic mirror plane and are connected by N-HO hydrogen bonds. In the crystal, the connectivity of the hydrogen bonds leads to double chains propagating in .
