We revisit the issue of higher-dimensional counterterms for the N = (1, 1) supersymmetric Yang-Mills (SYM) theory in six dimensions using the off-shell N = (1, 0) and on-shell N = (1, 1) harmonic superspace approaches. The second approach is developed in full generality and used to solve, for the first time, the N = (1, 1) SYM constraints in terms of N = (1, 0) superfields. This provides a convenient tool to write explicit expressions for the candidate counterterms and other N = (1, 1) invariants and may be conducive to proving non-renormalization theorems needed to explain the absence of certain logarithmic divergences in higher-loop contributions to scattering amplitudes in N = (1, 1) SYM.
