We present a singly charged scalar extension of the Scotogenic model, ScotoZee, which resolves the recently reported deviations in W boson mass as well as lepton g-2. The model admits a scalar or a fermionic dark matter while realizing naturally small radiative neutrino masses. The mass splitting of ∼ 100 GeV, required by the shift in W boson mass, among the inert doublets fields can be evaded by its mixing with the singlet scalar, which is also key to resolving (g-2)_ℓ anomaly within 1σ. We establish the consistency of this framework with dark matter relic abundance while satisfying constraints from charged lepton flavor violation, direct detection as well as collider bounds. The model gives predictions for the lepton flavor violating τ→ℓγ processes testable in upcoming experiments.
