Where to mail t4 summary

A T4 summary is a document that summarizes an individual's employment income and deductions for the year, and it's typically mailed to the Canada Revenue Agency (CRA) by the employer. Here are the mailing addresses for T4 summaries:

For employers in Canada:

• If you're an employer with a mailing address in Canada, you can mail your T4 summaries to the CRA at:
  • Canada Revenue Agency
  • T4 Processing Centre
  • 395 Silver Creek Parkway
  • Mississauga, ON L5B 2K9

For employers outside of Canada:

• If you're an employer with a mailing address outside of Canada, you can mail your T4 summaries to the CRA at:
  • Canada Revenue Agency
  • International T4 Processing Centre
  • 400, rue de la Couronne
  • Longueuil, QC J4H 3Z9

Electronic filing:

• You can also file your T4 summaries electronically through the CRA's My Business Account or the Represent a Client service. This is a faster and more secure way to submit your T4 summaries.

Important deadlines:

• The deadline for employers to mail or file T4 summaries is February 28th of each year, or June 15th if your business is a corporation.
• If you're filing electronically, the deadline is also February 28th, or June 15th if your business is a corporation.

Remember to keep a copy of your T4 summaries for your records, as they may be required for tax purposes.
