Employers love supplementing wage and salary income with bonuses. It’s an excellent way to reward top performers and motivate employees to do more than the bare minimum. Yet bonuses can quickly change one’s tax return depending on the size of the payout, the pertinent IRS guidelines, and how employers choose to handle it. Are bonuses treated as regular income, or singled out for special tax treatment? Are some types of bonuses more favorable than others? And are there any ways to minimize the tax impact of getting a bonus?
These questions are explored below:
Bonuses Are Considered “Supplemental Wages”
If you read the tax code, you will notice that the Internal Revenue Service goes to great lengths to categorize different types of income and treat them differently. Bonuses are another example of this. In the eyes of the IRS, bonuses are typically categorized as “supplemental wages.” As a University of Minnesota summary explains:
“The IRS defines supplemental wages as compensation paid in addition to the employee’s regular wages that includes, but is not limited to, severance or dismissal pay, vacation pay, back pay, bonuses, moving expenses, overtime, taxable fringe benefits, and commissions.”
As such, bonuses (like other supplemental wages) are treated differently than ordinary wage or salary income. There are two ways of taxing bonuses: the percentage method and the aggregate method. Which method gets applied to your bonus? Let’s find out.
The Percentage Method
The IRS specifies a flat “supplemental rate” of 25%, meaning that any supplemental wages (including bonuses) should be taxed in that amount. If you receive a $5,000 bonus, under this rule, $1,250 (25% of $5,000) goes straight to the IRS. Using this approach, the amount of your bonus – whatever it is – is “singled out” from the rest of your income and taxed directly. Employers frequently choose the percentage method because it’s easy and mindless to tax the entire bonus at a uniform rate.
In most cases, this is ideal from your standpoint as the bonus receiver and taxpayer, too. The aggregate method (described below), in addition to being more time-consuming and laborious for employers, can take a bigger tax bite out of your bonus payments.
The Aggregate Method
Unlike the much simpler percentage method, the aggregate method is when your employer adds the amount of your bonus (say, $5,000) to your most recent regular paycheck. Then, they determine the normal withholding amount based on IRS withholding tables for the sum of both amounts, subtract what was already withheld from your last paycheck, and withhold the rest from the bonus amount.
The problem with this approach is that instead of being taxed at a flat 25% – and having that 25% rate apply only to the bonus amount – you get taxed at what is almost certainly a higher rate on the combined amount of your normal pay and the bonus. The result: a higher overall tax obligation for the same amount of income.
Here is a free bonus calculator based on the aggregate method. Use it to determine your bonus-related tax obligation should your employer choose this approach.
Bonuses Exceeding $1 Million
What about high-end corporate bonuses, like those exceeding $1 million or more? These are singled out for higher taxes. If you receive a bonus of more than $1 million, your employer must withhold 35% of the amount above $1 million, as well as the standard 25% of the amount below $1 million. Of course, as discussed above, employers are not limited to the percentage method. They can, at their discretion, use the aggregate method for the bonus amount below $1 million.
In short: if you dislike the eye-popping bonuses top executives receive, you can take comfort in knowing how large a bite the IRS takes!
Why Does It Seem Like Bonuses Get Taxed More?
Employees often complain that their bonus checks have seemingly been taxed at much higher rates than their ordinary income. Yet, as The Street shows us by way of example, this is actually an illusion:
“If you make $2,500 a month but get a $5,000 midyear bonus, your withholding will be computed as if you received a single wage payment of $7,500 for the monthly payroll period. Then that $7,500 is annualized, or assumed to be part of your yearly salary. So if you earned $7,500 a month, you’d be making $90,000 annually versus $30,000. But at $90,000, your tax rate jumps to the 31% tax bracket vs. the 28%.
Under this annualized method, you would end up taking home even less of your bonus because you’d be withheld at much higher rates.”
What happened here is that your employer used the aggregate method to calculate your bonus withholdings instead of the simpler and smaller percentage method. The IRS didn’t apply a higher rate – your higher tax payment is simply a byproduct of the withholding method your employer chose.
Are you lucky enough to get a bonus this year? Which tax method will your employer use?
Tax Tip: If your bonus puts you in a higher tax bracket this year and you expect to make less next year, see if your employer can defer your bonus to lower your tax bill this year.
