Common T4 Slip Errors and How to Avoid Them
Incorrect SIN or Name
Ensure your Social Insurance Number and name match CRA records.
Missing Income or Deductions
Compare year-end pay stubs with the T4 slip for discrepancies.
Duplicate T4s
If you worked for the same employer twice in a year, ensure you received both T4 slips.
T4 Slips for Multiple Employers
If you worked for more than one employer during the year, you will receive a T4 slip from each. You must report income from all slips on your T1 return.
Key Filing Deadlines
- T4 slips must be issued by: February 28 (or 29 in a leap year)
- Tax return filing deadline: April 30 (or June 15 if self-employed, but taxes owed are still due by April 30)
Record-Keeping Requirements
You should keep your T4 slip Canada and supporting documentation for at least six years. CRA may request to review your records during an audit or reassessment.
Non-Residents and the T4 Slip
If you’re a non-resident of Canada but worked in the country and earned employment income, you’ll still receive a T4 slip Canada. This income must be reported, and non-resident taxes may apply. You may be able to claim a refund depending on tax treaties and credits.
Digital T4 Slips and E-Filing
Many employers now issue digital T4 slips. CRA-approved software can auto-fill your T4 data, making e-filing faster and reducing errors.
