A search for the lepton flavor violating decays tau--->l-KS0 (l=e or mu) has been performed using a data sample corresponding to an integrated luminosity of 469  fb[superscript -1], collected with the BABAR detector at the SLAC PEP-II e+e- asymmetric energy collider. No statistically significant signal has been observed in either channel and the estimated upper limits on branching fractions are B(tau--->e-KS0)<3.3×10[superscript -8] and B(tau--->mu-KS0)<4.0×10[superscript -8] at 90% confidence level.
