See in the next link the Minimum Wage Rate per State for Tipped Workers.
A tip is wage according to the Fair Labor Standard Act (FLSA). You are a tipped employee - that's for example a waitress or bellboy - if you receive regularly and customarily more than $30 a month in tip. If so, your employer is only required to pay $2.13 an hour in direct wages if that amount plus the tips received equals at least the federal minimum wage of $7,25 per hour.
Your employer can only do that if you are informed about the tip credit allowance, if your employer is able to show that you earn at least the minimum wage when direct wage and tip are combined and allows you to retain all tips.
When you are subject to both the federal and state wage laws you are entitled to the provisions of each law which provide the greater benefits.
When you don't receive sufficient tips to make up the difference between the cash wage of at least $2.13 per hour and the minimum wage of at least $7.25, your employer must make up the difference.
If you get only tips and you don't get paid the cash wage of at least $2.13 you must earn the full minimum wage of at least $7.25.
A tip is the sole property of the tipped worker regardless of whether the employer takes a tip credit. The FSLA prohibits any arrangement whereby any part of the received tip becomes the property of the employer! This rule does not apply however if there is a valid tip pooling or sharing arrangement among tipped workers - see below.
As noted above: as a tipped worker you cannot retain all tips if there is a valid tip pooling or sharing arrangement among workers who customarily and regularly receive tips. The FLSA does not impose a maximum contribution amount or percentage on valid mandatory tip pools. Your employer however, must inform you about any required tip pool contribution amount and may only take a tip credit for the amount of tips each tipped worker ultimately receives, and may not retain any of the workers' tips for any other purpose.
When you are required as a tipped worker to contribute to a tip pool that includes workers who do not customarily and regularly receive tips, you are owed all tips that you have contributed to the pool and the full minimum wage of $7.25.
If you are employed in both a tipped and a non-tipped occupation the tip credit is only available for the hours spent in the tipped occupation. However, the FLSA permits an employer to take the tip credit for some time that tipped workers spends in jobs related to tipped work, even though such duties are not producing tips. For example a waitress who spends some times cleaning and setting the tables, and occasionally washing dishes is considered to be engaged in a tipped occupation. However when you as a tipped worker spend over 20 percent of your workweek in a non-tipped occupation, no tip credit may be taken for the time spent in such duties.
Your employer must pay credit companies a percentage of each sale, so when your tips are charged on a credit card, your employer may pay you your tip, less the percentage of the credit card company. However, this charge on your tip may not reduce your wage below the required minimum wage. The amount due must be paid to you no later than the regular pay day and may not be held while your employer is awaiting reimbursement form the credit card company.
A compulsory charge for service is not a tip. Such charges - e.g. 15% of the bill - are part of your employer's gross receipts and may be used to satisfy your employer's minimum wage and overtime obligations under the FLSA.
