Abstract We investigate the anisotropic magnetic transports in topological semimetal TaSb$_2$. The compound shows the large magnetoresistance (MR) without saturation and the metal-insulator-like transition no matter whether the magnetic field is parallel to $c$-axis or $a$-axis, except that the MR for ${\boldsymbol B}\|c$ is almost twice as large as that of ${\boldsymbol B}\|a$ at low temperatures. The adopted Kohler's rule can be obeyed by the MR at distinct temperatures for ${\boldsymbol B}\|c$, but it is slightly violated as ${\boldsymbol B}\|a$. The angle-dependent MR measurements exhibit the two-fold rotational symmetry below 70 K, consistent with the monoclinic crystal structure of TaSb$_2$. The dumbbell-like picture of angle-dependent MR in TaSb$_2$ suggests a strongly anisotropic Fermi surface at low temperatures. However, it finally loses the two-fold symmetry over 70 K, implying a possible topological phase transition at around the temperature where $T_{\rm m}$ is related to a metal-insulator-like transition under magnetic fields.
