We discuss $ \mu-\tau $ reflection symmetry embedded in minimal seesaw model which predicts maximal atmospheric mixing angle and Dirac CP phase together with trivial Majorana phases for neutrinos. In this formalism, we add two right-handed neutrinos in the Standard Model which are essential to explain the tiny nature of neutrino mass under the type - I seesaw formalism. Assuming that both the left- and right-handed neutrino fields transform under $\mu-\tau$ reflection symmetry, we obtain the required forms of the neutrino Dirac mass matrix and the Majorana mass matrix for the right-handed neutrinos. To investigate the neutrino phenomenology at low energies, we first consider the breaking of $\mu-\tau$ reflection symmetry due to the renormalization group running. Later, we present a systematical study of different breaking schemes by introducing explicit breaking terms at Dirac and Majorana neutrino mass matrices respectively.
