Polling suggests no taxes on tips is a popular idea across party lines, but critics say the proposal will benefit few lower-income workers.

The bipartisan “no tax on tips” bill recently cleared the U.S. Senate with strong support, promising to eliminate federal income taxes on tipped earnings for qualifying workers.

The proposed legislation would add to the Internal Revenue Code of 1986 that certain tipped workers can receive a deduction on future tips and a credit for previously taxed cash tips.
