This paper reports an experimental test of the relative efficiency of a whistleblowing‐based audit scheme compared to a random‐based audit scheme. We design a between‐subjects laboratory experiment with two treatments: a benchmark with a random‐based audit scheme and an alternative treatment in which taxpayers can blow the whistle. Compared to the benchmark, the whistleblowing‐based audit scheme (i) improves the targeting of evaders, (ii) decreases the monetary amount of tax evasion, and (iii) raises the tax levy.
