Original T4A forms may show SIN number when placed in standard envelope
The Canada Revenue Agency (CRA) has recently identified a risk that under certain circumstances, the paper version of the original 2010 T4A form as well as the downloadable electronic version of the form could reveal the recipient’s Social Insurance Number box when it is placed in a standard T4 window envelope.
T4A forms are being reprinted and are being re-issued to everyone who has ordered and received the previous version.
Please note that some software may have been developed to conform to the previous 2010 T4A form and may not print information within the repositioned boxes on the revised form. Caution should be taken to ensure that confidential information is not visible through a window envelope.
If forms using the previous 2010 T4A form have already completed and distributed, do not re-issue them on the new form. However, ensure than any further T4A forms (original, amended, added, cancelled or replaced) are completed on the revised version of the form.
