Has the Spread of Tipping Reached Its Limit? Don’t Count on It.

Both major presidential candidates propose exempting tips from taxes. That could encourage more reliance on tipping, and leave workers vulnerable.

Americans are being asked to tip more often and in more places than ever before: at fast food counters and corner stores, at auto garages and carwashes, even at self-checkout kiosks. That has rankled many customers and divided both employers and tipped workers.

It may soon get worse. Both major-party presidential candidates have embraced proposals to eliminate income taxes on tips, a move that would, in effect, subsidize tipping and prompt more businesses to rely on it.

Economists across the political spectrum have panned the tax idea, arguing that it is unfair — favoring one set of low-wage workers over others — and could have unintended consequences. Even some tipped workers and groups that represent them are skeptical, worrying that over the long term the policy could result in lower pay.

But the debate alone underscores how service-sector workers have emerged from the pandemic as an economically and politically potent force. The spread of tipping in recent years was, in part, a result of the intense demand for workers, and the leverage it gave them. The presidential candidates’ dueling proposals signal that they see the nation’s roughly four million tipped workers as a constituency worth wooing.

“I do think it’s a reflection of this change in which people are finally hearing and recognizing that these workers matter,” said Saru Jayaraman, president of One Fair Wage, an advocacy organization. “Tipped workers had never seen their needs named in any way by any presidential candidate, ever.”

Ms. Jayaraman isn’t a fan of the tax exemption idea, though she is optimistic that the attention being paid to the issue could lead to policies she considers more important. One is the elimination of the subminimum wage, which allows businesses in some states to pay workers as little as $2.13 an hour as long as they receive enough in tips to bring them up to the full minimum wage.
