Inflation is from those with assets denominated in dollars (if they are not inflation adjusted). It is to those with liabilities denominated in dollars (if they are not inflation adjusted) and to the people introducing the new dollars into circulation. In the case of the government printing money, that's the government (obviously) and it's fairly reasonable to consider it a tax like any other. A somewhat regressive tax, since the more wealthy usually have more flexibility about how they store their wealth, but I don't know how it compares to sales taxes.
