Author: BlakeATO(Community Support)Community Support 24 Oct 2021Hi @RichardP If your partner no longer has access to that phone number, she will need to create a new myGov account. Once she does this, she will need to re-establish the link with her services. There are ways to link up without having to contact us, which you can read about on our website here: https://www.ato.gov.au/General/Online-services/Create-your-myGov-account-and-link-it-to-the-ATO/ If she's unable to establish a link using these details herself, she will need to contact us for a linking code. Unfortunately, Tax Time means you may experience longer wait times to speak with an operative when you call us, so try outside of our peak times by calling us when it's early morning or later in the evening for us. You can find how to contact us here: https://www.ato.gov.au/about-ato/contact-us/ Alternatively, you may wish to use a wi-fi calling service. This means you'd use wi-fi to connect, rather than cellular data. This can avoid connection fees.
