Tax enforcement may affect both the behavior of those directly treated and of some taxpayers not directly treated but linked via a network to those who are treated. A large-scale randomized field experiment enables us to examine both the direct and network effects of letters and in-person visits on withheld income and payroll tax remittances by at-risk firms. Visited firms remit substantially more tax. Their tax preparers’ other clients also remit slightly more tax, while their subsidiaries remit slightly less. Letters have a much smaller direct effect and no network effects, yet may improve compliance at lower cost.
