We calculate three-loop corrections to the effective action for $N=1$ supersymmetric electrodynamics regularized by higher derivatives. Using the obtained results, we investigate the anomaly problem in the considered model.
Keywords: supersymmetry, regularization, higher covariant derivatives, dimensional reduction.
