While bonuses may be taxed just like regular wages, payroll companies often calculate withholdings at a different rate for bonuses than the rest of your income. This depends on the method used for your withholdings. Some companies use the “Percentage Method”; while others use the “Aggregate Method”. Both are explained in more detail below.
The percentage method essentially requires that a flat “supplemental rate” of 25% be withheld for taxes. So if you receive a $1,000 bonus, the percentage method would dictate that $250 (25% of $1,000) go straight to the IRS. Employers often choose this method because of its simplicity.
The aggregate method requires your employer to combine the amount of your bonus with your most recent paycheck. Then, the withholdings are calculated based on the total amount necessary for that particular paycheck. Because withholdings are calculated based on year-end earnings as if you were earning this amount every paycheck, you’re likely to see excessive withholdings for any pay period that includes a bonus. This is especially true if your bonuses are a large percentage of your income.
For example: if you get paid monthly at a rate of $3,000 per month ($36,000 per year) and get a year-end bonus of $6,000, your withholdings for that year-end paycheck will be computed as if you receive $9,000 per month in pay. For payroll calculations under the aggregate method, that $9,000 is assumed to be 1/12th of your annual salary. Therefore, your paycheck would be withheld as though you make $108,000 for the year instead of the more accurate $42,000 ($36,000 salary + $6,000 bonus). Because the U.S. is on a progressive tax system, the tax rate increases on higher levels of income. So you would see higher withholdings for this paycheck than you will actually face in taxes.
What You Can Do
If you know a bonus check is coming and you feel the withholdings will be too high, you can request your employer lower these withholdings. This will allow you to keep more of the money now, rather than having to wait until tax time to recoup the over-withholding. Or you can just keep your withholdings at current levels, knowing you can expect an adjustment when your tax returns are prepared.
** Just be careful you don’t swing too far the other way and have your bonus under-withheld. We suggest checking with your tax preparer to ensure you do this correctly. Contact us...we can help!
*** If you change withholdings, be sure to change them back to normal levels after your bonus check.
