The goal of our paper is to demonstrate the potential effects of a tax on paying a ransom on the incentives of stakeholders involved: both the perpetrators (the attackers placing the ransomware) as well as the potential victim. We do think that there is a case for a ransom tax, but we do also realise that it is not easy to make that case, and hence we express this doubt in our title. A tax could stimulate ex ante cybersecurity and also (when price elasticity is not too low) reduce ex post ransom payments. In addition, a tax in combination with a smartly designed subsidy could have benefits.
