We evaluate the expected measurement accuracy of the branching ratio of the Standard Model Higgs boson decaying into tau pairs at the ILC with a full simulation of the ILD detector concept. We assume a Higgs mass of 125 GeV, a branching ratio of BR(h → τ+ τ-) = 6.32%, a beam polarization of electron (positron) of -0.8(+0.3), and an integrated luminosity of 250 fb-1. The Higgs-strahlung process e+ e- → Zh with Z → qq is analyzed. We estimate the measurement accuracy of the branching ratio Δ(σ× BR) / (σ× BR) to be 3.4% with using a multivariate analysis technique.
