We study the effect of dividend taxes on the payout and investment policies of publicly listed firms. We exploit a unique setting in Switzerland where, following the corporate tax reform of 2011, some but not all firms were suddenly able to pay tax-exempt dividends. We show that treated firms increase their dividend payout by around 30 after the tax cut. The effect on payout is less pronounced for firms prone to agency conflicts. We find a significant positive abnormal stock return after the announcement of the payment of a tax-exempt dividend. However, reducing dividend taxes does not boost investment.
