This paper studies optimal earnings taxation in a three‐period life‐cycle model where taxes can be differentiated according to age. Agents choose their level of education when young and their retirement age when old. I study the problem both without and with borrowing constraints. It is shown that, without borrowing constraints, a first‐best optimum can be decentralized by setting a zero tax rate in the third period and a first‐period tax lower than the second‐period one. With borrowing constraints, the first best can no longer be achieved. The gap between the first‐ and second‐period tax rates is larger, while the third‐period tax rate is generally different from zero.
