  We study the intermediate tachyon inflation in an anisotropic background. By
using the Friedmann equations obtained in the anisotropic geometry, we obtain
the slow-roll parameters in the tachyon model. The presence of the anisotropic
effects in the slow-roll parameters changes the perturbation parameters in our
setup which may change its observational viability. To check this, we perform a
numerical analysis and test the results with Planck2018 TT, TE, EE
+lowE+lensing+BK14(18)+BAO data. We show that the intermediate anisotropic
inflation in some ranges of the anisotropic and intermediate parameters is
observationally viable. We also show that the equilateral amplitude of the
non-gaussianity in our model is of the order of $10^{-2}-10^{-1}$. By studying
the reheating process in our setup, we find that it is possible to have
instantaneous reheating in this model. We also find that the temperature during
the reheating in our setup is consistent with Big-Bang nucleosynthesis.
