This Practice Statement is issued under the authority of the Commissioner and must be read in conjunction with Law Administration Practice Statement PS LA 1998/1. It must be followed by Tax officers unless doing so creates unintended consequences. Where this occurs officers must follow their Business Line's escalation process.

STATEMENT

1. This practice statement sets out:

the signature requirements for making declarations in 'approved forms' which are lodged electronically with the Commissioner or given to the Commissioner by telephone, and
the process which Tax Office staff must follow when approving an 'electronic signature' or a 'telephone signature' as defined in subsection 995-1(1) of the Income Tax Assessment Act 1997 (ITAA 1997).

Attachment A contains a glossary of terms and abbreviations used in this practice statement.

2. The signature requirements for documents that are sent to the Tax Office by facsimile transmission are not dealt with by this practice statement.

Electronic and telephone lodgment of 'approved forms' - declaration and signature requirements

3. The meaning of the term 'approved form' as used in this practice statement is explained in Law Administration Practice Statement PS LA 2005/19. Forms that are lodged electronically or given by telephone are referred to as 'virtual forms' in PS LA 2005/19.

4. Generally an approved form that is lodged with or given to the Commissioner must contain a declaration from the person lodging or giving the form that any information in the document is true and correct: sections 388-60 and 388-65 in Schedule 1 to the Taxation Administration Act 1953 (TAA). The Commissioner may give written approval for a form not to contain a declaration.

5. Where the form is lodged electronically, it must contain the declaration of the person giving the form with their electronic signature (subsection 388-75(3) in Schedule 1 to the TAA). The purpose of the signed declaration is to have the person making the statements in the document attest to the truth and correctness of the information given to the Commissioner.

6. Similarly, for documents given by telephone, subsection 388-75(4) in Schedule 1 to the TAA requires the document to contain the telephone signature of the person giving the document.

7. Only the Commissioner, a Second Commissioner or an SES officer holding the appropriate delegation from the Commissioner (the approving officers) may approve the electronic or telephone signature requirements for an approved form. The approving officer must approve a signature that:

is adequate to authenticate the identity of the person lodging or giving the document, and
minimises the risk that the statements made in the document can be repudiated or denied by the person lodging or giving the document.

The officer approving the related approved form may also approve any electronic and/or telephone signature required by that form, as referred to in paragraph 9 of Law Administration Practice Statement PSLA 2005/19.

8. The approving officer for an electronic signature should ensure that the approved form includes a dialogue box containing the declaration details required by sections 388-60 and 388-70 in Schedule 1 to the TAA (see paragraph 4 above).

9. Similar requirements must be followed when approving a telephone signature. Instead of a dialogue box the Tax Office's interactive voice response (ATO IVR) system will outline the appropriate declaration to which the preparer will verbally respond.

10. Approving officers must record in writing the electronic or telephone signature and their approval of the signature requirements. Standard forms of instruments of approval are at Attachments B and C for electronic and telephone signatures respectively.

11. Instruments of approval must be held as ancillary material to the instruments of approval for the related approved forms in accordance with the administrative support arrangements set out in paragraph 10 of Law Administration Practice Statement PSLA 2005/19. Therefore a separate register for them is not required. However, business lines may decide to create such a register. As stated in paragraph 10 of PSLA 2005/19, these arrangements are not part of the approval process for electronic and telephone signatures.

12. Electronic and telephone signatures will be approved on the basis of business practicalities and system capabilities such as developments in lodgment technology.

13. A number of Acts administered by the Commissioner have electronic signature requirements that are not covered by the signature provisions in section 388-75 in Schedule 1 to the TAA or the definition of electronic signature in subsection 995-1(1) of the ITAA 1997. In approving electronic signatures for provisions in those Acts, approving officers must follow the process outlined in this practice statement.

14. The tables in Attachment D list some of the different electronic and telephone signatures which have previously been approved for use with these forms of transmission.

EXPLANATION

Signed declarations in approved forms

15. Where a person or their agent is required to make a statement in a document to be given to the Commissioner, the relevant taxation law usually requires a signed declaration that any information in the document is true and correct (section 388-60 and 388-65 in Schedule 1 to the TAA). A statement that is false or misleading can result in an administrative penalty under subsection 284-75(1) in Schedule 1 to the TAA, or constitute an offence under section 8K or section 8N of the TAA.

16. Taxation documents are generally required to be given in the approved form. Section 388-50 in Schedule 1 to the TAA sets out the requirements for approved forms. Law Administration Practice Statement PS LA 2005/19 explains the procedures for approval of approved forms.

17. If an agent is providing information in an approved form on behalf of another entity, section 388-70 in Schedule 1 to the TAA requires the agent to make a declaration to the Commissioner about the document being given. The dialogue box must state that:

the document has been prepared in accordance with the information supplied by the other entity;
the agent has received a declaration from the other entity stating that the information provided to the agent is true and correct, and
the agent is authorised to give the document to the Commissioner.

Electronic and telephone signatures on approved forms

18. Under subsection 388-75(3) in Schedule 1 to the TAA, approved forms that are lodged electronically by a person must contain the person's declaration under section 388-60 with the person's electronic signature. Where forms are lodged electronically by an agent, they must contain the agent's declaration under section 388-70 with the agent's electronic signature.

19. Similarly, under subsection 388-75(4) in Schedule 1 to the TAA approved forms that are given by telephone must contain the person's or agent's telephone signature.

20. The term 'electronic signature' of an entity is defined in subsection 995-1(1) of the ITAA 1997 as 'a unique identification of the entity in electronic form that is approved by the Commissioner'. This gives the Commissioner a broad discretion to determine the appropriate signature to be used on documents that are transmitted electronically to the Tax Office. A person may be required by the Tax Office to have more than one electronic signature.

21. Some electronic signatures are complex digital identifiers, such as the digital certificates issued to businesses that lodge business activity statements over the Internet using the electronic commerce interface system (ECI). Others can be as simple as a personal identification number (PIN). For documents lodged by a registered tax agent using the electronic lodgment service (ELS) the electronic signature is a combination of the tax agent's registration number and a unique ELS approved number.

22. The term 'telephone signature' of an entity is also defined in the same broad way in subsection 995-1(1) of the ITAA 1997 as 'a unique identification of the entity that can be given by telephone and that is approved by the Commissioner'.

Approving electronic and telephone signatures

23. The authority to approve an electronic or telephone signature rests with the Commissioner, a Second Commissioner or SES officer holding the appropriate delegation or authorisation from the Commissioner.

24. Whenever the Tax Office accepts that an approved form can be lodged electronically or given by telephone, it must approve the electronic or telephone signature requirements for that form.

25. In each instance the officer approving the signature requirements must be satisfied that the identity of the entity giving the approved form can be authenticated, and that statements made by that person cannot be repudiated. This ensures the integrity of the data and prevents a person who has given an approved form from denying it was theirs.
