Koide's mass formula is an empirical relation among the charged lepton masses which holds with a striking precision. We propose a mechanism for cancelling the QED correction to Koide's formula. This is discussed in an effective theory with U (3) family gauge symmetry and a scenario in which this symmetry is unified with SU (2)L symmetry at 102 - 103   TeV scale.
