After you file your corporation income tax (T2) return

After we assess your return, we mail you a Notice of Assessment and, if necessary, an explanation of any changes we made to the return.

As soon as you receive the notice of assessment, compare it to your copy of the corporation's return. If you do not agree with the assessment, find an error, or have questions about the assessment, contact us.
