A method for preparing a thiomethylphenol derivative is provided to prevent oxidation and discoloration of a thiomethylphenol derivative produced in the presence of a base, and to allow application of a colorless thiomethylphenol derivative in various industrial fields. A method for preparing a thiomethylphenol derivative comprises the steps of: reacting a phenol derivative represented by the following formula 2, a mercaptan derivative represented by the formula of R2SH and paraformaldehyde in the presence of a C4-C10 heterocyclic amine type base and an acid to obtain a thiomethylphenol derivative represented by the following formula 1; and washing and purifying the resultant product with 1-50 equivalents of an acid per equivalent of the base. In formulae 1 and 2, R1 is H, a C1-C16 linear or branched alkyl, or aromatic group-containing alkyl; R2 is a C1-C16 linear or branched alkyl or aromatic group-containing alkyl; X is H, -(CH2)n-, -CMe2- or -Y-, wherein Y is an aromatic compound such as benzene, biphenyl, toluene or naphthalene, or an aromatic compound substituted with at least one alkyl group; n is 0 or an integer of 1-8; and m is 0 or 1.
