IP box regimes reward ownership of successful technology by imposing a lower tax rate on income derived from the commercialization of patented products relative to other sources of business income. Coupled with explicit provisions regarding the eligibility of acquired intellectual property, IP boxes may affect merger and acquisition (M&A) incentives through multiple channels. Applying panel difference-in-differences and event study methods at the firm level, we examine the effects of these modified incentives on the probability that a firm is acquired in the context of international and domestic acquisitions. In IP box regimes with strict nexus requirements, reducing the tax rate on patent income by 1 percentage point is associated with a 2.5 percent reduction in the probability of being acquired for patent-owning firms due to the potential loss of eligibility for preferential taxation. This effect dissipates where nexus requirements are relaxed. Significant positive effects of IP box tax savings on M&A activity in the latter more permissive regimes are indicative of increased after-tax valuations of merger-driven synergies.
