The Taubes current is introduced by Taubes in (J Symplectic Geom 9:161-50, 2011) as an intermediate step to construct almost K?hler forms. In this paper, we prove that an almost complex structures being almost K?hler structure in dimension four is the equivalent of the existence of Taubes currents. Precisely, we show that Taubes currents could be regularized to almost K?hler forms up to small perturbations of cohomology classes on any 4-dimensional almost complex manifold $(M, J)$ . A similar result is established for higher dimensions under the assumption of almost K?hler. An application to Donaldson’s “tamed to compatible-question is provided.
