If a worker receives gratuities and/or tips regularly in the course of employment from other than the employer, the gratuities and/or tips so received, if reported in writing to the employer, shall be considered taxable. The entire amount of charge tips are covered wages and are taxable to the maximum base even though the employee has not reported the entire amount to the employer. If the employee omits reporting tips, but the employer considers tips as part of an hourly rate for meeting the requirements of a Federal or State minimum wage law, it is considered that, in effect, tips have been reported to the employer to that extent and are therefore included as taxable wages.
