Considering a convex concealment cost function, I propose a formula for the optimal marginal tax rate, that generalizes the formula of the standard Mirrlees model to the case of tax avoidance. I also show that the results obtained by Casamatta (2021) in the fixed income case hold true when labour supply is endogenous: with a low enough marginal cost of avoidance, it is optimal to let some taxpayers, located in the interior of the skill distribution, avoid taxes. publisher: Blackwell Publishing date: 2023-08 type: Article type: PeerReviewed identifier: Casamatta, Georges (2023) Optimal income taxation with tax avoidance and endogenous labor supply.
