Abstract
The nucleon mass corrections are calculated to all polarized structure func tions for neutral and charged current deep inelastic scattering in lowest o rder in the coupling constant. The impact of the target mass corrections on the general relations between the twist-a and twist-3 parts of the structu re functions is studied and three new relations between the twist-3 contrib utions are derived. The size of nucleon mass corrections for the gl and gz structure functions are estimated.
