Seems like that will kill the overtime deduction for cops and fire fighters.
It may help some food servers though, with the tip tax deduction.
But in reality, exempting tips from taxable income will help very few workers. First, very few low-wage workers receive tips. If you look at those earning less than $25 per hour, which is just less than half of the workforce, only 5.1% are in traditionally tipped occupations.
Second, many tipped workers already dont pay federal income tax. According to researchers at the Brookings Institute, 37% of tipped workers earn so little that they pay no federal income tax.
Moreover, exempting tips from taxation will lead to cases where low-income workers end up effectively losing income through losing eligibility to tax credits such as the Earned Income Tax Credit (EITC) and Child Tax Credit (CTC). https://www.epi.org/blog/no-tax-on-tips-will-harm-more-workers-than-it-helps-proposals-in-congress-and-now-20-states-could-encourage-harmful-employer-practices-and-lead-to-tip-requests-in-virtually-every-co/
