We present a series of numerical models suitable for X-ray polarimetry of accreting systems. Firstly, we provide a spectropolarimetric routine that integrates reflection from inner optically thick walls of a geometrical torus of arbitrary size viewed under general inclination. In the studied example, the equatorial torus surrounding an accreting compact object is illuminated by a central isotropic source of X-ray power-law emission, representing a hot corona. Nearly neutral reprocessing inside the walls is precomputed by Monte Carlo code STOKES that incorporates both line and continuum processes, including multiple scatterings and absorption. Applying a conversion script to the torus reflection output, we created tabular dependencies for a new XSPEC model, called xsstokes. In this version, xsstokes enables efficient X-ray polarimetric fitting of the torus parameters, observer's inclination and primary emission properties, interpolating for arbitrary state of primary polarization. We provide comparisons of the results to a more sophisticated Monte Carlo simulation. Since the polarization interpolation routine works for any axially symmetric reflecting structure, we provide another version of xsstokes that is suitable for approximating nearly neutral reflection from a distant optically thick disc of small geometrical thickness. The second version uses the same precomputed Monte Carlo reprocessing, but assumes local illumination averaged for a range of high incident angles, representing a toy model of a diffuse, vertically extended hot inner accretion flow. Assessing both model variants, we conclude that the resulting polarization can be tens of % and perpendicularly/parallelly oriented towards the axis, if the reflecting medium is rather vertically/equatorially distributed.
