Quantaco is Upgrading Your ATO Mail System

Introducing ATO SmartDocs

Faster, Safer and More Reliable

At Quantaco, we’re committed to improving how we support you. That’s why we’re upgrading the way you receive important correspondence from the Australian Taxation Office (ATO).


From now on, all ATO mail will be delivered via ATO SmartDocs, our secure, digital mail system designed for speed, security, and simplicity.

Why Are We Changing?

ATO SmartDocs is already helping firms across Australia improve the way they receive and manage ATO mail. By connecting directly to ATO servers, it automates the document retrieval process, achieving up to 95% greater efficiency than manual handling.

In addition, SmartDocs creates a ‘Vault’, a secure, ongoing archive of your ATO correspondence. This means all your ATO documents are stored in one place, accessible anytime you need them.

Why Did We Choose ATO SmartDocs?

Enhanced Security

ATO mail contains sensitive personal and financial data. SmartDocs reduces the risk of exposure by avoiding traditional mail and unsecured email.

Environmentally Friendly

Digital delivery eliminates the need for paper, stamps, and transport, reducing your environmental footprint.

The ATO now uses up to six different delivery methods. SmartDocs ensures you don’t miss any important notices, lodgement deadlines, or payment reminders.
