The γγ physics at KLOE-2 experiment is made possible after the recent KLOE upgrade with new small angle tagging detectors along the DAFNE beam line. These taggers allow to detect the final leptons coming from process e+e−→e+e−γ*γ* giving the possibility to measure the transition form factor of the pseudoscalar mesons. These measurements provide constraints to the models used to calculate the hadronic light-by-light contribution to the muon anomaly. The KLOE-2 prospects for γγ physics of the new data-taking, started in November 2014 with the upgraded detector, are reviewed.
