Supplemental Wages

Supplemental wages are additional, non-regular compensation that an employee might receive, often as a bonus or overtime pay. These wages are separate from their normal salary or hourly rate and are subject to their own form of tax withholding. Examples of supplemental wages include severance pay, awards, prizes, back pay, commission, and payment for accumulated sick leave.

What Is Supplemental Wages?

Supplemental wages are additional compensation paid to an employee above their regular wages. They may include bonuses, overtime pay, payment for accumulated sick leave, severance pay, awards, prizes, back pay, retroactive pay increases, and payment for non-deductible moving expenses. Supplemental wages are generally subject to income tax withholding, social security, and Medicare.

How Do You Calculate Supplemental Wages?

Calculating supplemental wages depends on how they are paid. If the supplemental wages are lumped into an employee's regular wages, you simply withhold federal income tax as you normally would.

However, if the supplemental wages are identified separately from the regular wages (like a bonus), you have two methods to choose from for federal income tax withholding:

  1. Flat rate method: You withhold a flat 22% (as of 2022) for federal income tax from these wages. For this method to be used, the employee must have received wages subject to withholding in the current or previous year.

  2. Aggregate method: Add the supplemental wages to the regular wages for the most recent payroll period. Then, withhold tax on the total amount of wages (regular plus supplemental) based on the tax tables for the appropriate payroll period. This method generally results in a higher tax withholding rate, as the combined amount may push the employee into a higher tax bracket for that period. Afterwards, the supplemental amount is deducted from the total, leaving the regular wages and the amount of tax to be withheld from the regular wages.

What Are Some Examples of Supplemental Wages?

Some common examples of supplemental wages include:

  • Bonuses
  • Commissions
  • Overtime pay
  • Payments for accumulated sick leave
  • Severance pay
  • Awards and prizes
  • Back pay
  • Retroactive pay increases
  • Pay for non-deductible moving expenses
  • Taxable fringe benefits
  • Expense allowances under a non-accountable plan.

What's the Difference Between Supplemental Wages and Bonus Pay?

Supplemental wages is a broad category that includes all forms of compensation paid to an employee in addition to their regular wages. This could encompass numerous types of payments, such as bonuses, overtime pay, commissions, severance pay, and awards, among others.

Bonus pay, on the other hand, is a specific type of supplemental wage. It is an additional payment given to an employee over and above what's stipulated as part of the employee's normal salary or hourly wage. Bonuses are often awarded for exceptional performance, meeting or exceeding company goals, or as part of profit-sharing plans. In essence, all bonus pay is supplemental wage, but not all supplemental wages are bonus pay.

What Are Some Examples of Bonus Pay?

Some common examples of bonus pay include:

  • Performance bonuses: These are typically awarded for achieving specific business goals, meeting targets or completing a project successfully.
  • Signing bonuses: This type of bonus is often used as an incentive to attract key employees. The bonus is typically paid upon starting a new job.
  • Profit-sharing bonuses: A portion of the company's profits may be distributed to employees as a bonus. The amount usually depends on the company's earnings and the employee's designated share.
  • Retention bonuses: This is a payment designed to retain key employees during periods of change such as mergers and acquisitions.
  • Holiday bonuses: These are paid around a specific holiday, typically as a token of appreciation for the employees' hard work throughout the year.
  • Spot bonuses: These are unplanned bonuses given for exemplary performance or for employees who go beyond the required duties of their positions.
  • Sales commission: Paid to salespeople as a percentage of the sales they make, serving as a strong incentive to close deals.

What's the Difference Between Supplemental Wages and Overtime Pay?

Supplemental wages is a broad category that encompasses all forms of additional compensation paid to an employee over and above their regular wages. This includes such payments as bonuses, overtime pay, commissions, awards, and other similar forms of additional earnings.

Overtime pay, on the other hand, is a specific type of supplemental wage that's given to employees for working hours that exceed their standard work schedule, typically over 40 hours per week. In the U.S., the Fair Labor Standards Act requires that non-exempt employees receive overtime pay at a rate of one and a half times their regular rate of pay for all hours worked beyond 40 in a workweek.

In short, all overtime pay is a form of supplemental wage, but not all supplemental wages are overtime pay.

What Factors Contribute to the Determination of Supplemental Wages?

Several factors contribute to the determination of supplemental wages:

  1. Employee's job role or occupation: Certain roles, particularly in sales or jobs with performances incentives, may offer bonuses or commissions as supplemental wages.

  2. The company's policies: Some companies have established policies regarding supplemental wages, such as regular bonuses, profit sharing systems, or overtime pay.

  3. Performance: Often, performance-based bonuses or commissions are used as supplemental wages to incentivize and reward high-performing employees.

  4. Hours worked: Overtime pay comes into play when an employee works more than the standard number of hours in a workweek.

  5. Special circumstances: Situations such as severance, signing bonuses, retroactive pay increases, or payment for non-deductible moving expenses can also result in supplemental wages.

What Advantages Do Employees Gain From Receiving Supplemental Wages?

Employees can enjoy several advantages from receiving supplemental wages:

  1. Increased Income: The most immediate benefit is an increase in their total income. This additional income can significantly improve an employee's financial situation.

  2. Motivation and Retention: Bonuses and other forms of supplemental wages can motivate an employee to perform at their best and meet company goals. They can also improve job satisfaction and help retain key employees.

  3. Reward for Exceptional Performance: Supplemental wages often serve as a reward for hard work, dedication, and exceptional performance, acknowledging the employee's contributions to the company.

  4. Employee Well-being: Some forms of supplemental wages, like overtime pay, ensure that employees are compensated fairly for all the hours they work, promoting a healthy work-life balance.

  5. Financial Relief in Special Situations: Certain types of supplemental wages, like severance pay, can offer financial relief to employees in the event of job loss.

What Potential Drawbacks Could Arise From Employees Receiving Supplemental Wages?

Despite their advantages, supplemental wages could also present several potential drawbacks:

  1. Increased Taxation: Supplemental wages, like bonuses and commissions, are typically subject to income tax, sometimes at a higher rate than regular income.

  2. Dependence on Variable Income: If employees begin to rely heavily on bonuses or commissions, variability in these payments can cause financial instability.

  3. Fairness and Morale: If not managed and distributed fairly, supplemental wages can lead to perceived inequity, resentment, and lowered morale among employees.

  4. Misaligned Incentives: Performance-related supplemental wages could potentially encourage short-term thinking or unhealthy competition if not aligned with long-term company goals.

  5. Potential for Exploitation: Some less scrupulous companies might use supplemental wages as an excuse to pay lower base salaries, or expect unreasonable hours or effort as a "trade-off" for potential bonuses.

Which Employers Are Likely to Be Affected by Supplemental Wages?

Supplemental wages can affect a wide range of employers across various sectors, including but not limited to:

  1. Businesses in the Sales and Retail Industry: They often provide commissions or performance bonuses, which are types of supplemental wages.

  2. Companies with Overtime Work: Industries with frequent overtime (like healthcare, technology, manufacturing, or logistics) often pay supplemental wages in the form of overtime pay.

  3. Firms with Seasonal Work: During peak periods, these companies may use bonuses or additional pay to incentivize and compensate employees for extra work.

  4. Corporations: They often use bonuses, stock options, and profit-sharing programs as supplemental wages to incentivize and retain top executives and high-performing employees.

  5. Start-up Companies: They may offer signing bonuses or equity shares (a form of supplemental wage) to attract skilled employees.

  6. Companies Going Through Change: Businesses dealing with mergers, acquisitions, or laying off employees may pay severance pay, a type of supplemental wage.

Essentially, any employer that provides additional compensation beyond regular wages may deal with the implications of supplemental wages.
