There is a persistent myth that just won’t go away: that sometimes it’s better to make less money than more money. For example, if you’re making $82,499, you’d pay 22% in federal income tax and if you make a dollar more you’ll pay 24%.

One look at a tax table, provided by the IRS, shows this is absolutely wrong.

“No way. The tax code doesn’t work that way.” says Vincent Cervone, a CPA in New York. “Ultimately, you always come out on top when you make more money.”

That’s the beauty of a marginal tax system, in which each bracket has a range of incomes that are taxed at a particular rate. For example, even though Facebook CEO Mark Zuckerberg is in the highest tax bracket (37%), he only pays 10% federal income tax on the first $9,525, and 12% on the income above that up to $38,700, and so on.

Still, the internet is full of stories of people who go so far as to decline a pay raise because they think it will net them less money.

Yahoo Finance asked several CPAs whether someone would ever make less money because of a higher salary. None of them could think of any circumstance where it would be advantageous, except in very specialized cases.

Cliffs in the tax code

There are many tax credits and deductions that have income limits. However, these were designed to not shut off completely if you exceeded that income threshold so you aren’t incentivized to make less. However, these credits and deductions, similar to the tax code, are based on brackets, so there can be a staircase aspect to it.

For example, if your adjusted income is $25,049, your earned income tax credit is $2,332. If you make a dollar more, it goes down by $8, leaving you $7 short. So you can technically earn more and take home less in that situation. Still, though, this $7 is pretty darn small and shows that the phasing works pretty well.

Many income-tested tax benefits have small instances like this, but they typically don’t mean much. For example, if your adjusted gross income is $119,999, you’re eligible to contribute $5,500 to a Roth IRA, a tax-advantaged savings vehicle for retirement. But if you make $120,000 — just a dollar more — your maximum contribution is capped at $4,950.

Obamacare complicates this

There is one area in which the phase-out system seems broken, which could incentivize someone to make less. Health insurance premium increases — particularly in Obamacare plans, largely thanks to the Trump administration – have resulted in Obamacare’s subsidy to malfunction.

People with modified gross adjusted income (MAGI) at 400% or less of the poverty limit ($48,240 for an individual) are eligible for subsidies under the law. But if you make $1,500 more, for example, you are not eligible for subsidies. How bad this is for an individual depends largely on their age. For a young person, the cliff may not be significant, but for a 64-year-old (especially if you’re living somewhere without much competition among insurers) it’s huge, as HealthInsurance.org pointed out.
