After you file your T4A-NR information return

When the CRA receives your information return, the CRA checks it to see if you have prepared it correctly. After an initial review, the CRA enters your return into our processing system, which captures the information and performs various validity and balancing checks. If there are any problems, the CRA may contact you.

After filing your information return, you may notice that you made an error on a T4A-NR slip. If so, you will have to prepare an amended slip to correct the information.
