State legislators have already proposed a number of digital and data tax bills in 2021, some of which are new proposals while others reintroduce proposals from previous legislative sessions.  The proposed bills fall into one of three categories: taxes on digital advertising services, taxes (or fees) targeting social media providers, and taxes on the sale or monetization of personal data.  Most of the proposals are in the early stages, but a Maryland bill originally introduced last year is moving closer to a legislative vote on whether to override the governor’s veto.
