Frequently asked questions.
Why does the ATO require agent nomination?
Client-to-agent linking was introduced to strengthen security and prevent unauthorised access to taxpayer accounts. Until you nominate us, we cannot see your ATO account, review your lodgment history or act on your behalf.
Where do I complete the nomination?
In the ATO's Online services for business, under Profile then Agent details. You will need your myGovID (now myID) linked to the business. We walk you through every screen on a call.
How long do we have?
Once you submit the nomination, we have 28 days to accept it. If it lapses, the nomination has to be started again - another reason to do it together on a call.
What is LINK Advisors' registered agent number?
LINK ADVISORS PTY LTD is registered tax agent 25504639. That is the number you enter when you nominate us, and you can verify it yourself on the Tax Practitioners Board public register at https://myprofile.tpb.gov.au/public-register/practitioner/?ran=25504639 before you type it in anywhere.
Is it safe to nominate an agent I found online?
Check them on the TPB register first - that is exactly what it is for. Search the agent number, confirm the entity name matches who you are talking to, and confirm the registration is current with no conditions on it. Then nominate. Any legitimate agent will give you their number without being asked, which is why ours is on this page.
Five minutes on the phone and it's done.
We'll complete your nomination together on the phone - then get straight into the work that actually matters.
