TFN risk: Tax File Numbers are among the most sensitive personal information under the Privacy Act 1988. When client TFNs are handled in Gmail or Outlook, every email is transmitted through US-jurisdiction servers — a clear Privacy Act APP 8 risk that the ATO takes seriously.

Regulatory Landscape

Accounting email compliance in Australia

Every compliance obligation that applies to accounting email — and how ShieldBox satisfies each one.

ATO / Tax Administration
Tax Administration Act 1953

Tax agents must retain client records including email correspondence for 5 years from lodgement. ATO audits can request these records at any time. WORM-archived email satisfies this obligation automatically.

Privacy Act / TFN
Privacy Act 1988 — TFN Guidelines

Tax File Numbers are subject to the TFN Rule under the Privacy Act. The Tax File Number Guidelines restrict how TFNs can be collected, stored, used, and disclosed — including via email and cloud storage.

Professional Bodies
CPA Australia & CA ANZ

CPA Australia and Chartered Accountants ANZ require members to maintain secure client records and protect client confidentiality. Offshore email hosting is a compliance risk under both bodies' professional standards.

Privacy Act Part IIIC
NDB Scheme

Accounting practices handle clients' tax records, financial statements, and TFNs — all categories that trigger NDB notification if accessed without authorisation. Phishing remains the primary attack vector.

Platform Features

Everything accounting needs

Built from the ground up for Australian compliance requirements specific to accounting.

Client TFNs never leave Australia

All client financial data, tax returns, and TFN communications stored exclusively in Australian data centres. ATO TFN Guidelines satisfied by design.

7-year ATO-compliant archiving

Automatic WORM archiving for every email. Configurable retention by engagement type. ATO-auditable exports produced on demand.

Encrypted client file exchange

Encrypted portal for sending and receiving tax documents, financial statements, and signed authorities — eliminating insecure email attachments.

NDB breach detection

Automated detection of compromised accounts accessing client tax records. 30-day OAIC notification clock managed in-platform.

Partner and staff access controls

Partners, senior accountants, graduates, and admin each have configurable access permissions. Client data segregated by engagement team.
