When is the last day to provide registration information for filing for the current period?


You have returns to add but haven't received the registration information yet. What is the last day that you can provide that information to be able to file for the current month?




  • The deadline to update the filing calendar to adjust (edit) or add a new return to be filed is the end of each month.
    • For example, update your filing calendar to file a return for the January tax period in the month of January. After the end of January, changes apply to the new month moving forward. Changes and additions made in February apply to the February return.
  • If it's past the deadline, we can still file the return late. Learn more at Amend and File Late.
