CRA error code N1 indicates that the name, Social Insurance Number (SIN), or date of birth entered in your tax return does not match the CRA's records. To fix this, carefully verify these personal details against your last year’s tax return, SIN card, or documents from Service Canada.
Steps to Resolve N1 Error:
- Verify Personal Info: Ensure the first name, middle name, last name, and SIN are exactly as they appear on your official documentation.
- Check Birth Date: Ensure the day/month/year of birth is not mixed up.
- Name Change: If you recently changed your name, the CRA may not have updated records yet.
- First-time Filer: Confirm all name/SIN details are correct.
- Alternative Solution: If all information is correct, you may need to call the CRA at 1 (800) 959-8281 to verify what they have on file.
