T4 Boxes 30 to 88 - Other Information

The “Other information” area at the bottom of the T4 slip has boxes for you to enter codes and amounts that relate to employment commissions, taxable allowances and benefits, deductible amounts, fishers’ income, and other entries if they apply. The boxes are not pre-numbered as in the top part of the slip. Select the proper code from the drop-down menu provided.

Note: The program does not support a situation where more than six codes apply. If more than six codes apply to the same employee, use an additional T4 slip. Do not repeat all the data on the additional slip. Enter only the employer’s name and address, employee’s SIN and name, and complete the required boxes in the “Other information” area. Report each code and amount only once.

The instructions below will provide details on the contents of boxes 30 to 88.

Where applicable, the amounts shown in these boxes must include the applicable GST, HST or PST.

In addition, the amount of taxable benefits reported may be affected if the employee is:

at a special or remote work site; or
living in a designated area.
