Using data collected with the CLEO II detector at the Cornell Electron Storage Ring, we have studied the decays of tau leptons produced through e{sup +}e{sup -} annihilation into final states containing K{sub S}{sup 0} mesons, observed through their decays to {pi}{sup +}{pi}{sup -}. We present branching fractions for decays to five final states: {tau}{sup -} {yields} K{sup 0}h{sup -}{nu}{sub {tau}}, {tau}{sup -} {yields} K{sup 0}h{sup -}{pi}{sup 0}{nu}{sub {tau}}, {tau}{sup -} {yields} K{sup 0}K{sup -}{nu}{sub {tau}}, {tau}{sup -} {yields} K{sup 0}K{sup -}{pi}{sup 0}{nu}{sub {tau}}, and {tau}{sup -} {yields} K{sub S}{sup 0}K{sub S}{sup 0}h{sup -}{nu}{sub {tau}}, where K{sup 0}h{sup -} denotes the sum of the processes involving {bar K}{sup 0}{pi}{sup -} and K{sup 0}K{sup -} particle combinations. Substructure and mass spectra in these final states are also addressed.
