3He spin-dependent structure functions, g31(x) and g32(x), which parametrize the hadronic tensor in polarized deep-inelastic scattering, were evaluated within the Poincaré covariant light-front framework. The Bakamjian-Thomas construction of the Poincaré generators allows us to make use of a realistic 3He wave function, obtained from refined nuclear phenomenological potentials. The same approach was already successfully applied to the 3He and 4He unpolarized deep-inelastic scattering. To investigate the neutron polarized structure functions, gn1 and gn2, a readily implementable procedure, aimed at extracting the neutron spin structure functions from those of 3He, is shown to hold. Moreover, the first moment of g31(x) was evaluated, aiming at providing a valuable check of the Bjorken sum rule. The present analysis is relevant for experiments nvolving polarized beams planned at the future facilities, like the Electron Ion Colliders.
