Non-cash incentive awards, such as merchandise from a local retailer given to its employees or vacation trips offered to the employee team member who contributes the most to a special project, are a form of supplemental wages and are subject to most of the reporting and withholding requirements of other forms of compensation that employees receive. There are, however, special rules for calculating and timing withholding, as well as exceptions for de minimis awards and "length of service" awards.  

Withholding, depositing, and reporting

Similar to regular pay, employers must withhold income, Social Security, Medicare, and federal unemployment taxes from non-cash incentive awards based on their fair market value. Employers must deposit the tax withheld, along with matching payments of Social Security and Medicare taxes, during the period the incentive award is deemed to be paid. Employers must also report incentive awards on Form W-2, Wage and Tax Statement.  

Calculating withholding rules  

However, since non-cash incentive awards are considered supplemental wages, employers have several different options in calculating withholding. For incentives paid along with regular pay not separately specified on the pay stub, employers may withhold payroll taxes at the normal rate as if the employee simply received a larger paycheck.

For incentive awards paid separately from regular pay, employers have a choice of combining the two and withholding the normal rate or withholding the normal percent from the regular pay and a flat 25 percent from the incentive award.  

But, for those fortunate employees who receive incentive awards in excess of $1 million, the employer is required to withhold at a flat rate equal to the highest income tax rate (currently 35%).  

Timing

Special timing rules apply to withholding for non-cash incentive awards. Employee compensation is ordinarily treated as a "pay-as-you-go" tax, meaning that employers are required to withhold payroll taxes periodically throughout the year, rather than all at once at the end of the year. Employers are allowed to withhold taxes on incentive awards, on the other hand, by the pay period, by the quarter, or on any other consistent basis as long as it is paid at least once a year.  

Timing requirements become stricter, however, for personal investment property and real property given to employees as incentive awards. For these categories, the date the property was actually transferred must be used to determine when the employee was "paid."

Withholding exceptions

Noncash incentive awards given to employees that have a de minimis value are excluded from wages and therefore not subject to withholding. Taking into account how frequently similar benefits are given to employees, the award must have little value and cannot be in the form of cash.

Finally, length-of-service or safety achievement awards equal to or less than $1,600 made under a qualified plan, or $400 otherwise, are excluded from wages and therefore not subject to withholding as well.  The only exception is that a sole proprietor can't give such a tax-free award to him or herself.
