T4A Summary – Information for payers

On this page

What is a T4A Summary

The T4A summary (T4ASUM) represents the total of the information reported on all of the T4A slips you prepared for each recipient for the calendar year.

You can get a Form T4ASUM in a PDF or PDF fillable/saveable format to file on paper.


T4A Summary

What to report

  • Report all amounts in Canadian dollars, even if they were paid in another currency. Learn about the average exchange rates: Exchange rates
  • Fill out a separate T4A Summary for each one of your payroll accounts. The totals you report on your T4A Summary have to agree with the total of all amounts you reported on your T4A slips for that payroll account
  • If you have no amounts to report on a T4A slip or summary, there is no need to send either form to the CRA
  • Do not change your address using the T4A Summary. Learn more about making changes: Make changes to your account
