Communication history

Communication history gives you access to view available correspondence we send to you or your agent using the following channels:

email
SMS
paper
agent digital – used to send digital communications to your agent when they have set up Communication preferences to receive mail on your behalf
ATO online – used to send a digital copy of a statement of tax record and digital activity statement notice.

Some communications can't be sent digitally. These will continue to be sent by post and can't be viewed in Communication history. We will continue to add more communication types to enhance this function further.

If you are a sole trader, you will need to use ATO Online services for individuals and sole traders to view your communication history.

To view your communication history, select:

Communication
Communication history.

To search using specific parameters, select:

Type
- Communications – list of available digital correspondence sent to you

Print friendly version to print or save a copy.

You can view and download a digital activity statement notice for quarterly GST and PAYG instalments (forms R, S and T) if you lodge activity statements electronically.

To view and download your digital activity statement notice from the client home page, select:

Communication
Communication history
Search
- select Activity statements tick box, and deselect Communications tick box
- select Time period and then Search – this will display the digital activity statement notice.

If your registered delivery preference is paper, we will continue to send paper instalment notices. We don't change your delivery preferences from paper to electronic unless you have lodged electronically.

Communication preferences

If you use a tax agent, Communication preferences allows you and your agent to choose where we send your digital ATO communications.

You can choose to have communications sent to either:

you
your registered agent.

You can also choose to have some communications sent to you and others to your registered agent.

Your agent can set your communication preferences on your behalf.

If you or your agent elect to have communications sent to them, you can request a copy from them.

Your dealings

You can track the progress of the messages you've sent us using Your dealings in the Communications menu.

Troubleshooting secure mail

To send secure mail messages, you will need:

a separate secure mail message for each subject
ensure you attach all supporting documentation, which
- is a maximum of 6 files
- is less than 6 MB in size (per file)
- is in a suitable format (doc, .pdf, .rtf, .xls, .xml, .tif, .jpg, .zip, .bmp, .png, .gif, .mpp, .ppt, .docx, .dotx, .xlsx, .xltx, .pptx, .potx, .ppsx.)
- is not encrypted (for example, password protected)
- doesn’t contain macros
- doesn’t contain formulas (copying and pasting information from one spreadsheet to another may introduce unseen elements in your spreadsheet)
- is not an executable file (common executable file extensions include .exe, .app, .vb, .scr).

Mailbox size limit

Warnings will appear when a mailbox is approaching or has exceeded the 500-message limit. The limit includes both emails in your mailbox and sent emails.

You will be asked to delete mail items to reduce your mailbox size. Exceeding the limit will impact a user's ability to create new emails or reply to received emails.

Prior to deleting any messages, you should save copies of individual emails:

open the email by clicking on the email hyperlink
select the Printer friendly button to print or save as a PDF.

You can also save a list of messages in your own inbox or sent items by using the Printer friendly button (located at the bottom left of your screen). This gives you the option to print a hard copy or save the list as a PDF.

Alternatively, you can view a list of sent emails in Your dealings. This includes the status of the request.
