We have investigated the electromagnetic moments of the tau lepton in $e^{+}{e}^{-}\to e^{+}{\gamma }^{*}{\gamma }^{*}{e}^{-}\to e^{+}\tau \overline{\tau }{e}^{-}$ process at the CLIC. We have obtained 95% confidence level bounds on the anomalous magnetic and electric dipole moments for various values of the integrated luminosity and the center of mass energy. We have shown that the $e^{+}{e}^{-}\to e^{+}{\gamma }^{*}{\gamma }^{*}{e}^{-}\to e^{+}\tau \overline{\tau }{e}^{-}$ process at the CLIC leads to a remarkable improvement in the existing experimental bounds on the anomalous magnetic and electric dipole moments.
