Purchasing OnePay

OnePay can only be purchased from within ProFile, where you'll be directed to a secure web page to complete your OnePay purchase.

You will receive an email confirmation (the access code you receive will not be entered into ProFile).


What you need to know

  • 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.
