CRA T4 Slip Missing or Wrong (2026): Where to Find It + What to Do Before You File

Missing your T4 slip or finding incorrect information on it can be stressful, especially during tax season. Fortunately, the Canada Revenue Agency (CRA) offers several ways to locate, correct, or replace your T4, and there are steps you can take to avoid filing errors that could delay your refund or trigger reassessment.

45-Second Summary

• You can view or request copies of your T4 slip from the CRA’s “My Account”. ([turn0search0])
• If it’s missing, contact your employer or check online — CRA often has electronic copies. ([turn0search10][turn0search7])
• If the information is wrong, the employer must issue an amended T4 slip. ([turn0search5][turn0search20])

Where Your T4 Slip Should Come From

Your T4 slip reports your employment income, CPP/QPP contributions, EI premiums, and taxes withheld. Employers are required to provide this slip to you before the end of February each year so you can file your tax return. ([turn0search0][turn0search12])

Step-By-Step: What to Do if Your T4 Is Missing

1. Check CRA “My Account” Online
   Many slips are submitted to the CRA electronically by employers, so your T4 may already be available online. Log in and check under “Tax information slips”. ([turn0search0])
2. Contact Your Employer
   If it’s not in your CRA account, ask your employer for a copy. Confirm they have your correct mailing address and email. ([turn0search22])
3. Call the CRA
   If your employer can’t provide it, call the CRA individual enquiries line (1-800-959-8281) and ask for a copy. Be ready to verify your identity. ([turn0search7][turn0search1])
4. Estimate and Declare
   If you still can’t get your T4 before filing, you can estimate income from pay stubs and include a note with your return explaining your actions. ([turn0search0])

What to Do If Your T4 Slip Has Incorrect Information

Mistakes can happen — incorrect income, wrong Social Insurance Number (SIN), or wrong deductions. Employers can issue an amended or replacement T4 slip. They file a corrected information slip with the CRA and provide you with a copy. ([turn0search5][turn0search20])

Filing Without a T4 or With a Wrong Slip

You can still file your tax return even if a T4 is missing or has an error, but it must be accurate. If you estimate income or deductions, keep all supporting documents — such as pay stubs or employer statements — in case the CRA asks for verification later. ([turn0search0])

Common Mistakes to Avoid

• Waiting too long to contact your employer — slips are usually due by end of February. ([turn0search0])
• Assuming the CRA will automatically correct errors — the employer must send an amended slip. ([turn0search5])
• Failing to check “My Account” before filing. ([turn0search0])

Checklist: Before You File Your Return

• ✔ Check CRA “My Account” for your T4 and other tax slips.
• ✔ Confirm your employer has your correct address and email.
• ✔ Ask for an amended T4 slip if any information is incorrect.
• ✔ Keep copies of pay stubs and documents if you estimate income.

FAQ

Q. What if I can’t find my T4 online?
A. Contact your employer first; if they can’t provide it, call the CRA to request a copy. You may also estimate income and keep records until the CRA provides the official slip. ([turn0search0][turn0search7])

Q. Can I file my return without a T4?
A. Yes — you can estimate using pay stubs and include supporting documentation. Just keep everything in case the CRA follows up. ([turn0search0])

Q. How long does the employer have to issue an amended T4?
A. Employers file amended T4s electronically or on paper; once submitted, CRA updates your information. You should receive a copy promptly. ([turn0search5][turn0search20])
