When electioneering, the best pledges are catchy enough to get stuck in a voter’s head. During this election, “no tax on tips” seems to be the phrase fitting that bill. Both presidential candidates are embracing the promise to exempt workers from paying taxes on their tips.

But the problem with no-tax-on-tips proposals, experts say, is that they’re clearly a bid for votes rather than a substantive solution to address the fundamental needs of tipped workers. “This wouldn’t help very many workers, and it could actually be very harmful to millions more, with the real benefits of this policy change going to employers and the wealthy at the expense of working people,” says David Cooper, researcher from EPI Action, a nonpartisan research and advocacy organization. On June 9, former President Donald Trump made a promise to end taxes on tips in front of service workers in Las Vegas.

Last weekend, in Las Vegas, Vice President Kamala Harris made a similar pledge. It’s no coincidence that both candidates made the announcement in Las Vegas — leisure and hospitality is the dominant industry in the metro area, Bureau of Labor Statistics data shows. On Monday, White House press secretary Karine Jean-Pierre said that President Joe Biden also supports eliminating taxes on tips for service and hospital workers, as well as raising the minimum wage.

The policy is undeniably appealing for tipped workers and the unions that represent them. After all, who doesn’t want a tax brea.
