Abstract. A key motivation for the two-photon physics program of the BESIII collaboration is the need of high precision data on electromagnetic transition form factors as input to the calculations of the contribution of hadronic Light-by-light scattering to the anomalous magnetic moment of the muon. The data collected with the BESIII detector allow to study the momentum dependence of the form factors at small momentum transfers, which is of special relevance for a µ . In this presentation the ongoing measurements of the transition form factors of π 0 , η and η mesons, as well as pion pairs, are discussed, and the potential for first double-tagged measurements at BESIII are pointed out.
