Form SS313 authorises a person or an organisation to enquire or act on your behalf for Centrelink payments and services, including aged care matters. Services Australia uses it to set up four kinds of arrangements: a person permitted to enquire, a person permitted to update, a correspondence nominee, and a payment nominee. Each level gives the authorised person a different set of things they can do for you.
You can fill out SS313 directly in the Universal PDF editor. Complete the customer parts and the authorised person or organisation parts on screen, then download the finished PDF to print, because the declarations must be signed by hand before you lodge the form.
What is Form SS313 used for
The form records your consent for someone else to deal with Centrelink for you and defines how far that authority goes. A person permitted to enquire can ask questions about your payments and services. A person permitted to update can also give Centrelink information to update your record. A correspondence nominee can additionally report changes, complete and sign forms, attend appointments, and receive copies of your letters. A payment nominee receives your Centrelink payments and must use them only for your benefit.
You can tick more than one arrangement type on the same form, but you can only have one correspondence nominee and one payment nominee at a time. Lodging a new arrangement of the same type automatically cancels the existing one, and the previous nominee is told by letter.
Who uses Form SS313
Centrelink customers use it to authorise a family member, friend, professional, or organisation to help with their affairs. If the customer can make their own decisions but cannot sign, a Power of Attorney may sign the customer declaration. If the customer cannot make their own decisions, an appropriate third party, such as a treating professional or the holder of an enduring Power of Attorney, guardianship, or administration order, can sign the third party authorisation with supporting evidence.
An authorised organisation must supply its Australian Business Number and will need Provider Digital Access (PRODA) registration to use nominee services online. Authorised people and attorneys are asked to show photo identification in person at a service centre, agent, or access point.
How to fill out Form SS313
The form is split between the customer and the person or organisation being authorised. Work through it in order:
- Part A: enter your Customer Reference Number, name, date of birth, and address, then select the arrangement types you want and how long they should last.
- Part B: record the authorised person's name, date of birth, and contact details, or the organisation's trading name, ABN, and contact person.
- Part C: sign the customer declaration, or arrange the third party authorisation if the customer cannot make their own decisions.
- Part D: the authorised person or organisation lists any legal orders they hold, sets a contact password of 4 to 12 letters or numbers, and signs their own declaration.
- Payment nominees also provide the account details where payments should be deposited.
- Attach copies of any Power of Attorney, guardianship, or administration documents listed in the checklist.
How to submit it
Return the form and supporting documents online through your Centrelink online account (identity documents excluded), by post to Services Australia, PO Box 7800, Canberra BC ACT 2610, by fax to 1300 786 102, or in person at a service centre. Identity checks for authorised people are done face to face.
You can cancel a nominee arrangement at any time by phone, in writing, through your online account, or at a service centre, unless it was put in place by a court, tribunal, guardianship, or administration order. Services Australia can also review, reject, or cancel arrangements.
Frequently asked questions
Yes. Authorising a person or organisation does not remove your own access. You can keep contacting Services Australia directly, and you can cancel the arrangement whenever you choose, unless it is court or tribunal appointed.
You can authorise more than one person permitted to enquire or update, but only one correspondence nominee and one payment nominee at a time. A separate form is needed for each arrangement of those types.
No. If you are paid more than you are entitled to, you repay it, not your nominee. A payment nominee must, however, keep records showing your payments were spent for your benefit, and those records can be reviewed.
An authorised person or attorney needs to show photo identification, such as an Australian driver licence or valid passport, in person at a service centre, agent, or access point. Organisation staff verify their identity when creating a PRODA account.
This form covers Centrelink payments and services, including aged care. Services Australia has separate authorisation processes for Medicare and Child Support, described at servicesaustralia.gov.au/authorisedrepresentative.
