Supplemental Wages: Definition, Taxation, and Examples

A comprehensive guide to understanding supplemental wages, including bonuses, commissions, overtime pay, and certain types of sick pay, along with the tax withholding methods and FAQs.

Supplemental wages refer to payments made to employees in addition to their regular earnings. These can include bonuses, commissions, overtime pay, and certain types of sick pay. Supplemental wages are distinct from an employee’s standard wage and often have different tax withholding requirements.

Types of Supplemental Wages

Bonuses

Bonuses are extra payments made to employees, usually as a reward for good performance, achieving certain targets, or during the holiday season.

Commissions

Commissions are payments made to sales employees based on the sales they achieve, generally calculated as a percentage of the sales amount.

Overtime Pay

Overtime pay is the additional pay received by employees who work beyond their normal working hours. This is typically calculated at a higher rate than regular pay.

Sick Pay

Certain types of sick pay can also be considered supplemental wages, especially if they are paid in a lump sum or for extended periods.

Taxation of Supplemental Wages

Percentage Method

An employer can opt to withhold a flat 25% rate for federal income tax on supplemental wages. This method is generally simpler but may not always result in the correct tax amount for the employee’s specific situation.

Aggregate Method

Alternatively, the employer can add the supplemental wages to the regular wages and use the same withholding method as for regular wages. This may require more calculations but could be more accurate for reflecting the employee’s overall tax liability.

Examples

Bonus Example

An employee receives a year-end bonus of $5,000. Under the percentage method, the employer withholds 25%, resulting in $1,250 withheld for federal income tax.

Commission Example

An employee earns a $2,000 commission. The employer withholds $500 based on the flat 25% rate.

Historical Context

Historically, the categorization of supplemental wages evolved to simplify the payroll process and ensure proper tax withholding. The IRS established guidelines to help employers accurately withhold taxes from various types of additional earnings.

Applicability

Understanding supplemental wages is crucial for both employers and employees. Employees need to know how their additional income is taxed, while employers must ensure compliance with federal tax laws.
