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.
