We present a search for neutral supersymmetric Higgs bosons
decaying to tau pairs produced in p anti-p collisions at s**(1/2) = 1.96 TeV.
The data, corresponding to 310 pb-1 integrated luminosity, were collected
with the CDF II detector at the Tevatron collider at Fermilab. No
significant excess above the standard model backgrounds is observed. We set
exclusion limits on the production cross section times branching fraction to
tau pairs for Higgs masses in the range from 90 to 250 GeV/c2.
