Abstract: A study of anomalous couplings of the Higgs boson to vector bosons and fermions is presented. The data were recorded by the CMS experiment at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 138 fb $^{-1}$ . The study uses Higgs boson candidates produced mainly in electroweak vector boson or gluon fusion that subsequently decay to a pair of $\tau$ leptons. Matrix element and multivariate techniques were employed in a search for anomalous effects. The results are combined with those from the $\mathrm{H}\rightarrow 4\ell$ and $\mathrm{H}\rightarrow\gamma\gamma$ decay channels to yield the most stringent constraints on anomalous Higgs boson couplings to date.
