  Weyl semimetals (WSM) exhibit chiral anomaly in their magnetotransport due to
broken conservation laws. Here, we analyze the magnetotransport of WSM in the
presence of the time-reversal symmetry-breaking tilt parameter. The analytical
expression for the magnetoconductivity is derived in the small tilt limit using
the semiclassical Boltzmann equation. We predict a planar Hall current which
flows transverse to the electric field and in the plane containing magnetic and
electric fields and scales linearly with the tilt parameter. A tilt-induced
transverse conductivity is also present in the case where the electric and
magnetic fields are parallel to each other, a scenario where the conventional
Hall current completely vanishes.
