In this work, we use the Faber polynomial expansions to find upper bounds for the coefficients of analytic bi-univalent functions in subclass Sigma(tau,gamma,phi) which is defined by subordination conditions in the open unit disk U. In certain cases, our estimates improve some of those existing coefficient bounds.
