Why is my taxable benefit added to the box 14 of my T4?

• Taxable benefits are considered as gross pay for the purposes of federal taxes so they should be included in Box 14 total income on the T4
• To show the benefit total on the other infomation of T4--when printing the T4 under T4 box options window, select the code beside the benefit to report it on Other information boxes of T4
• To verify that they are being included, go to Reports, Report Centre, Employees & Payroll, Employee Summary. Run it for the time frame in question
• The Gross Paid total shows the total of income, the Gross Pay total includes the income total plus taxable benefits
• Refer to the CRA web site in Additional Information for the definition of benefits
