We calculate chirally enhanced corrections to the muon's electric and magnetic dipole moments in two-Higgs-doublet models extended by vector-like leptons, we explore a sharp correlation between $h \rightarrow \mu^+ \mu^-$ these models. Among many detailed predictions, for model with new leptons same quantum numbers as standard find that $0.38 \lesssim \tan \beta 21$ necessarily requires muon moment be observed at near-future experiments, assuming is measured within $1\%$ of prediction current central value moment. In all studied models, predicted values can reach up experimental limits. Moreover, show some there two sources chiral enhancement, parametrizing complex number. This leads sign-preferred predictions
