  The potential of the process $\gamma \gamma \rightarrow \tau
\bar{\tau}\gamma$ is examined in a model-independent way using the effective
Lagrangian approach for the ILC which is designed with standard configurations
of 0.25 TeV/2000 fb$^{-1}$, 0.35 TeV/200 fb$^{-1}$ and 0.5 TeV/4000 fb$^{-1}$.
The limits obtained for $\tilde{a}_{\tau}$ and $\tilde{{d}_{\tau}}$ parameters
defining the anomalous $\tau \bar{\tau}\gamma$ couplings at $95\%$ confidence
level and systematic uncertainties of $\delta_{sys}=0,5,10 \%$ are compared
with the experimental results. The best limits obtained without systematic
error on the anomalous couplings are $-0.00082<\tilde{a}_{\tau}<0.00050$ and
$|\tilde{{d}_{\tau}}|<3.5969 \times 10^{-18}$ $e\,cm$, respectively. Thus, our
results show that $\gamma \gamma$ collisions at the ILC lead to a remarkable
improvement in the existing experimental limits on the anomalous magnetic and
electric dipole moments of the tau lepton.
