      Hi Sleet,

      Thanks for getting in touch with Finder. I hope all is well with you. 😃

      You can withdraw money from your Westpac Bump Savings Account to a Westpac everyday account. A person who can withdraw money is the Bump Savings account holder or an account signatory. You can withdraw via online transfers or visiting a branch. There are no fees for these withdrawals.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    Do we have to apply for a tax file number to give to Westpac for our baby’s new bump account in order to avoid her being taxed on interest earned in her account or is it exempt?

      Hi Dave!

      Thanks for leaving an inquiry on our page.

      No, the tax file number is not mandatory, however, it is helpful that you provide your tax file number or exemption to ensure that the correct withholding tax is being applied to your account.

      Hope this helps!
