In the title acids, C15H14O4S, (I), and C16H16O4S, (II), respectively, the angle between the planes of the benzene ring and the carboxyl group is 13.7 (1)° for (I) and 21.3 (1)° for (II). The molecular structures are stabilized by intramolecular C—H⋯O hydrogen bonds. The crystal packing is stabilized by a single O—H⋯O hydrogen bond in both compounds, in which the O and H atoms are ordered; H⋯O 1.87 Å for (I) and 1.83 Å for (II), O⋯O 2.680 (2) Å for (I) and 2.652 (3) Å for (II), and O—H⋯O 172° for (I) and 175° for (II). The hydrogen bond forms a cyclic dimer, with graph‐set descriptor R(8), about a centre of symmetry.
