The Senate unanimously passed the "No Tax on Tips Act," which would eliminate taxes on reported cash tips up to $25,000 for workers earning $160,000 or less.

The idea is firmly planted in the sprawling tax cuts package Republicans are hashing out in the House and aiming to pass in the coming days.

If enacted, the legislation would create a federal income tax deduction of up to $25,000 per year, with some limitations.
