Clarification. What is the steam tax you speak of? I understand when people use the term 'Apple tax' (for example), they're referring to a premium price on a premium product and the follow up premier prices that come with it. But as far as Steam's prices go - assuming the term is used in relation to the price of the products - I don't see any particular inflation over the price of games in a brick and mortar store. In fact, even comparing Steam prices to GOG or the Humble store, I don't think I've ever encountered any discrepancy in prices that points to a "steam tax".
