Abstract
The latest Higgs boson measurements in final states with tau leptons are reviewed. These measurements are based on 137 fb$^{-1}$ of data collected with the CMS experiment at centre-of-mass energy of 13 TeV. An overall signal strength of $0.85^{+ 0.12}_{- 0.11}$ with respect to the standard model prediction is observed. A measurement of the CP properties of the tau Yukawa coupling is also presented for the first time. The mixing angle between CP-even and CP-odd tau Yukawa couplings was found to be $4 \pm 17^{\circ}$. The observed significance of the separation between the CP-even and CP-odd hypotheses is 3.2 standard deviations.
