I am asking this question in relation to recent talk about exempting tipped wages from income tax. This is something that seems to be supported by both Kamala Harris and Donald Trump in their presidential campaigns this year.
No tax on tips: Why politicians love it, and economists don't
When it comes to tips is there anything specific that makes it a tip or would disqualify it from being called a tip? This is being asked due to the practice that some businesses have of adding a "mandatory" tip to the bill for various reasons such as the number of people in the party.
For the purpose of tax law today are/can these mandatory charges classified as tips or as something else?
