How do I apply for the ING Business Optimiser?

If you have determined that the ING Business Optimiser is the type of account that can boost your business savings, you can start an online application by visiting ING website.

Eligibility to apply

There will be some eligibility requirements that you will need to meet before getting started, such as:

  • Minimum age. This account is only available for individuals aged 18 and over.
  • Residency requirements. You must be an Australian resident with an Australian residential address.
  • Depository requirements. You must be able to provide the details of your linked account at the time of application so that ING can make the initial deposit when opening the account.

Documentation requirements

Additionally, when filling out the application you will be asked to provide certain documentation before the application can be processed. This will include:

  • Tax file number. In order for your earned interest to have the correct withholding tax applied to it you should provide your tax file number (TFN) or TFN exemption code.
  • Identification. Identifying documents will be needed for you and for any persons who will be listed as an authorised user. A photo ID such as a passport or driver’s licence is accepted.
  • Linked account. Details for a business transaction account in the same name, including institution and account number.
  • Business details. The Australian Business Number (ABN) or Australian Company Number (ACN) that your business is registered under.
  • Client number. If you are already an ING customer you will need to provide your client number.

What happens after I submit my application?

After submitting your application ING will need to verify the identity of you and your business, as well as the linked bank account. It will also make a request for the transfer of funds from your provided linked account details.

The account is opened when that request is made, and activated once the funds have been deposited into the account. You will then be notified of the account details so that you may make your own deposits and withdrawals.

    Can clients pay directly into the Business Optimiser account?

    • Avatarfinder Customer Care
      AshMarch 13, 2020Staff

      Hi Debb,

      Thank you for reaching out to Finder.

      Your clients may not directly deposit their payment to the ING Business Optimiser Account. Rather, you should have a Transaction Account linked to your Business Optimiser Account, which should be under the same Business Name, to which your clients will be depositing their payments to. Then you may have up to 4 authorised employees who will manage your Business Optimiser Account, to transfer money in and out of the account from your linked Transaction Account.

      Please make sure that you’ve read the relevant T&Cs or PDS of this account to help consider whether the product is right for you.

      I hope this helps.

    Hi, we are current ING account holders, am I able to open a ING Business Optimiser account?

    • Avatarfinder Customer Care
      NikkiAugust 14, 2019Staff

      Hi MacDonnells Law,

      Thanks for leaving a question. If you are an existing ING client? Just login to Online Banking, go to ‘Apply for Products’, choose “Business”, then “Business Optimiser” and following the prompts.

      Along with your application form, you need to mail ING:

      1. certified documents to verify your business;
      2. an original encoded deposit slip from the bank account you wish to link.
      Alternatively, a recent bank statement (no more than 6 months old)
      3. a copy of identification documents for each nominated authorized user such as a current Australian Drivers License, Birth Certificate or Australian Passport

      If you are able to visit Sydney CBD, one of ING’s staff at the ING Lounge can assist you with your online application.

      Hope this helps. Feel free to reach out to us again for further assistance.

    I am interested in opening an ING Business Optimiser Account. Do I have to open a separate linked account with ING or can I use my existing Westpac business account?

    • Avatarfinder Customer Care
      JeniFebruary 11, 2019Staff

      Hi Warren,

      Thank you for getting in touch with finder.

      You may use your existing Westpac business account. As per the FAQ part of this page you’re looking at, the account you link to the Business Optimiser must be a business account, and it can be from any Australian institution. The account must have a BSB and account number.

      I hope this helps.

      Thank you and have a wonderful day!

    Hi, im looking at the high intrest saving account fr business. when you say that the intro offer is 2.5% p.a for 6 months.
    Can you please explain how much interest do I make in 1 month? and could I leave the money for 5 months only?

    • Avatarfinder Customer Care
      NikkiDecember 20, 2018Staff

      Hi Anna,

      Thanks for getting in touch! The introductory 2.5% offer for 6 months means that the amount on the account will earn 2.5% each month in the first 6 months when you open an account. Your interest is calculated daily on the closing balance and added to your account at the end of each month, so you earn interest on your interest. You can withdraw the money anytime it’s needed and there is no minimum balance to keep the account. Hope this clarifies!

    Could I open a bank account and a savings account in ING Business Optimiser, in the name of a discretionary or family trust?

      AshDecember 20, 2018Staff

      Hi Trish,

      Thank you for contacting finder.

      Yes, you may open an ING Business Optimiser account under a Family Trust but the Authorised Users should not exceed 4 trustees.

      I hope this helps.

      Please do not hesitate to reach out again if you have additional questions.

    Hi there, with this business account do i get a debit card attached to the account for business expenses?

      JoelMarch 22, 2018

      Hi Naomi,

      Thanks for leaving a question on finder.

      ING Business Optimiser doesn’t come with a debit card as it’s a savings account.

      You may want to consider business bank accounts as they do come with a linked debit card.

    What is a linked account and why do I need to have one. What type of operations will I do to need a linked account. Is it mandatory to have a linked account? Can I transfer money to another savings account if I don’t have a linked account?


    • Default Gravatar
      Ash MunozMarch 10, 2018

      Hi Mayte,

      Thank you for visiting finder.

      You will need a Transaction Account linked to your ING Business Optimiser Online Savings Account to be able to withdraw money in case you need it. The linked account should also be a business account and under the same name as your savings account.

      Only a Transaction Account can be linked so you can transfer the money from your savings account via online, phone or by branch.

      I hope this helps.

      Let us know if there is anything else that we may assist you with. Enjoy the rest of your day!

    Are there fees for international transactions?

    • Avatarfinder Customer Care
      JonathanMarch 7, 2018Staff

      Hi Ros, thanks for your inquiry.

      International transactions are not supported with this savings account. You will need to link a transaction account in order to complete international transactions. You can compare personal savings accounts with ING here.
