Abstract
We document some features of the preliminary draft of the tau lepton averages for the incoming HFLAV report. We include the tau mass and lifetime averages, and a fit of measurements of tau branching fraction measurements. Elaborations of these results provide lepton universality tests and determination of |Vus| with tau measurements.

Report
Averaged values of tau lepton properties by HFLAV are presented, including tau mass, lifetime and branching fractions. Lepton universality is tested with unprecedented precision. Determination computation of the CKM matrix element |Vus| using tau decay data shows some tension with CKM unitarity.
