If you work in an industry where you receive tips, you need to pay Social Security and Medicare taxes on those earnings in addition to any hourly wages that you receive. However, if you already reported your tip income to your employer, then your employer may have already withheld these taxes from your paycheck. If you did not already report it to your employer, you will need to use Form 4137 to calculate the additional tax you owe on the unreported Tax Income.
Please visit Form 4137 Information for more information.
