29 CFR 531.59 - The tip wage credit.
(a) In determining compliance with the wage payment requirements of the Act, under the provisions of section 3(m) the amount paid to a tipped employee by an employer is increased on account of tips by an amount equal to the formula set forth in the statute (minimum wage required by section 6(a)(1) of the Act minus $2.13), provided that the employer satisfies all the requirements of section 3(m). This tip credit is in addition to any credit for board, lodging, or other facilities which may be allowable under section 3(m).
(b) As indicated in § 531.51, the tip credit may be taken only for hours worked by the employee in an occupation in which the employee qualifies as a “tipped employee.” Pursuant to section 3(m), an employer is not eligible to take the tip credit unless it has informed its tipped employees in advance of the employer's use of the tip credit of the provisions of section 3(m) of the Act, i.e.: The amount of the cash wage that is to be paid to the tipped employee by the employer; the additional amount by which the wages of the tipped employee are increased on account of the tip credit claimed by the employer, which amount may not exceed the value of the tips actually received by the employee; that all tips received by the tipped employee must be retained by the employee except for a valid tip pooling arrangement limited to employees who customarily and regularly receive tips; and that the tip credit shall not apply to any employee who has not been informed of these requirements in this section. The credit allowed on account of tips may be less than that permitted by statute (minimum wage required by section 6(a)(1) minus $2.13); it cannot be more. In order for the employer to claim the maximum tip credit, the employer must demonstrate that the employee received at least that amount in actual tips. If the employee received less than the maximum tip credit amount in tips, the employer is required to pay the balance so that the employee receives at least the minimum wage with the defined combination of wages and tips. With the exception of tips contributed to a valid tip pool as described in § 531.54, the tip credit provisions of section 3(m) also require employers to permit employees to retain all tips received by the employee.
