*DIS on a polarized spin-1 target with spectator tagging*
We discuss the process of deep-inelastic electron scattering (DIS) on 
the polarized deuteron with detection of a nucleon in the nuclear 
fragmentation region ("spectator tagging"). We cover (a) the general 
structure of the semi-inclusive DIS cross section on a spin-1 target; 
(b) the tagged structure functions in the impulse approximation, where 
deuteron structure is described by the NN light-front wave function; (c) 
the extraction of free neutron structure through on-shell extrapolation 
in the recoil proton momentum. As an application we consider the 
extraction of the neutron structure function F_2n and spin structure 
function g_1n through electron scattering on the (un)polarized deuteron 
with proton tagging and on-shell extrapolation. Such measurements would 
be possible at an Electron-Ion Collider (EIC) with polarized deuteron 
beams and forward proton detectors.  We comment on the influence of 
final-state interactions on these observables in kinematics at the EIC.
