Filing the T1204 information return (slips and summary)

A T1204 information return consists of the T1204 slips and the related T1204 summary.

How to file

If you file more than 50 slips for a calendar year, you must file the return over the Internet. For more information about filing electronically, see Filing Information Returns Electronically (T4/T5 and other types of returns).

Cancelling or amending slips

If you need to amend or cancel a slip after you have filed your return, see Amending returns.

Replacing slips

If you issue T1204 slips to replace copies that are lost or destroyed, do not send us a copy. Clearly identify them as "DUPLICATE" copies, and keep them with your records.

When to file

You have to file by March 31 of the year following the calendar year to which the information return applies. If March 31 falls on a Saturday, Sunday or public holiday, recognized by the CRA, your return is due the next business day.
