Tips as wages.
"Tips as wages" are those tips an employee is required to report to the employer by federal law.
(1) The employer must report tips each quarter on an "as paid" basis. Tips are considered paid when the employee reports them to the employer for federal income tax purposes; or when they are distributed by the employer to the employee.
(2) Tips will not be treated as wages when an individual's benefits are calculated if the individual did not report their value to the employer.
