Slips are prepared by your employer, payer, or administrator and must be issued by the last day of February of the following calendar year to which the slips apply. If you have not received, or have lost or misplaced your current year's T4 slip, or other information slip, you have to ask your employer or the issuer of the slip, for a copy. On the other hand, if you are filing a tax return for a prior year, and you have not received, or have lost or misplaced your information slips for that year, you can call 1-800-959-8281 for a copy of your slips for that year.
You may also choose to have us act as your representative and this link will take you to a PDF fillable form on the CRA-ARC site. You may also print out a copy and complete it by hand and submit it to your CRA office. Completion of this form gives the Canada Revenue Agency (CRA) your consent to deal with another person (such as your spouse or common-law partner, other family member, friend, or accountant) as your representative for income tax matters or to cancel any existing representatives on your file. Send this completed form to your CRA tax centre, or call 1-800-959-8281 to immediately cancel a consent. You can find the address of your tax centre on the included information sheet. You can also give or cancel a consent by providing the requested information online through "Authorize my representative" on the site at www.cra.gc.ca/myaccount.
