Abstract	This talk presents recent Belle II results on lepton flavor universality and flavour violation tests using B meson and tau decay. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event offer high precision measurements of B decays or rare decays with missing energy. Results from semileptonic and electroweak penguin decay will be discussed. Similar advantages exist for rare tau decay searches. A search for the lepton number violating decays tau -> l alpha is also presented.
