What you need to know
  • You must have an EFILE number to file T1 returns using OnePay.
  • Your taxpayer information MUST be correct as it cannot be changed later.
  • The purchase process attaches information to the specific return to complete the transaction, so you MUST save the return when the process is finished.
  • Once you've unlocked your tax return software, OnePay is not refundable.
