Tax Implications of Bonuses
You are not alone if you enjoy rewarding your team's performance with bonuses. But it's important to consider how those bonuses are given and the tax implications for you and the employee.
Percentages generally calculate one-time bonuses. For clerical and support staff, the rates cluster around 3% to 5% of annual salary. Managers might receive a low double-digit percentage, and executives in the mid-double-digit range. However, bonuses can also be flat rates.
You can generally deduct the cost of bonuses, assuming the bonus is compensation for services rather than a gift. If you use cash-method accounting, remember that you can't deduct bonuses paid in 2024 on your 2023 tax returns. Accrual-method businesses benefit from the rule that lets them deduct a bonus paid for performance in the past year if the employee receives it within 2 1/2 months of the year's end. If you miss that window, the IRS assumes that the bonus is deferred compensation, which is deductible in the year paid rather than the year earned.
An important caveat is that the 2 1/2-month rule applies only to nonrelated employees. If the employee is your spouse, child, sibling, parent, or grandparent, you must deduct the bonus in the year the recipient reports it as income, which is most likely the year it's paid.
Tax Considerations
Bonuses are considered supplemental wages. (Other supplemental wages are commissions, overtime compensation, severance pay, awards and prizes, back pay, tips, payments for nondeductible moving expenses, retroactive raises, and costs for accumulated sick leave.) That means you will withhold the usual FICA and federal unemployment tax and any applicable state taxes. The federal income tax withholding amount depends on the employee's total supplemental wages during the tax year.
If the supplemental wage payment exceeds $1 million, the first million gets taxed at 22%, and every dollar over that is taxed at 37%, which is the highest income tax rate for the year.
For supplemental wages of $1 million or less, you can choose one of the following methods for calculating tax:
If you pay supplemental wages with regular pay without specifying the amount, withhold federal income tax as if the total were a single payment for a regular payroll period.
If you pay supplemental wages separately or combine them in a single payment with wages and specify the amount of each, you can:
Withhold a flat 22% of the bonus. (So if the bonus, paid separately, were $100, you'd withhold $22 and cut a $78 check.)
Use the aggregate method—an IRS formula based on the employee's tax bracket (as given on a W-4)—to calculate the withholding amount. This is a more complicated method of calculating taxes but may better ensure you cover the employee's tax liability.
If you withhold more tax than necessary, the employee receives a refund. If you withhold too little, the employee is surprised when taxed.
A tax-free bonus is impossible. If you pay the employee's share of taxes on the bonus, taxes paid are considered additional wages and are subject to tax.
You may use bonuses to increase productivity, improve employee retention, thank your team for their efforts, and/or create a positive work environment. A bonus is always a welcome bump in pay.
