If you are behind 7 or more years
- The CRA Non-Filer page gives no set cut-off for how far back it can ask for returns. Do not assume older years are safe.
- Gather your slips. Many slips for recent years are available in CRA My Account. Older years may need other records.
- Talk with a tax professional before you file several years at once.
- Ask about relief for the last 10 years. If the total is too large to repay, talk with a Licensed Insolvency Trustee.
Every situation
- File the oldest year first.
- Ask for a payment arrangement if you cannot pay.
- Ask for relief on penalties and interest if you qualify.
- Use free help before you pay a stranger.
