Accounting firms are among the most targeted businesses in Australia by cybercriminals. They hold financial data, tax file numbers, bank account details, and business credentials for dozens or hundreds of clients — all in one place. A single breach doesn't just damage the firm; it exposes every one of their clients.
This guide is written for accounting firm principals and operations managers in Queensland who want to understand what their IT provider should be doing, what compliance requirements apply, and what "good" looks like for a firm of their size.
Why Are Accounting Firms High-Value Targets for Cybercriminals?
Accounting firms represent a highly efficient target for several reasons:
- Aggregated data — one firm holds sensitive financial data for many clients simultaneously, making it more valuable to attackers than targeting individual businesses
- ATO portal access — tax agents have privileged access to the Australian Tax Office's Business Portal, making compromised credentials extremely valuable
- Payment flow authority — accounting staff routinely authorise or process payments, making them prime targets for Business Email Compromise
- Deadline pressure — the peaks of tax season create conditions where staff are more likely to click a suspicious link without scrutinising it
- Client trust — clients are more likely to comply with fraudulent requests that appear to come from their trusted accountant
What IT Security Requirements Apply to Queensland Accounting Firms?
Several overlapping obligations apply:
Australian Privacy Act 1988
Accounting firms that handle personal information for clients are subject to the Privacy Act. This requires reasonable security measures to protect personal information and mandates notification obligations when a data breach occurs that is likely to result in serious harm (Notifiable Data Breaches scheme).
Tax Practitioners Board Professional Standards
Registered tax agents must maintain systems that protect client data and comply with the Tax Agent Services Act. The TPB has published guidance specifically on cyber security obligations for tax practitioners.
Professional Indemnity Insurance Requirements
Most professional indemnity insurers are now asking detailed cybersecurity questions on renewal. Firms that cannot demonstrate basic controls — MFA, patched systems, encrypted backups — are facing higher premiums or coverage exclusions for cyber incidents.
ASD Essential Eight (Recommended)
While not mandatory for private firms, aligning to Essential Eight Maturity Level 1 or 2 provides a practical, structured baseline that satisfies most insurer, client, and regulatory expectations simultaneously.
What Should a Managed IT Provider Do for an Accounting Firm?
A managed IT provider working with an accounting firm should deliver, at minimum:
| Service Area | What It Should Cover for Accounting Firms |
|---|---|
| Multi-Factor Authentication | MFA enforced on Microsoft 365, ATO systems, accounting software, and all remote access |
| Email Security | Anti-phishing, anti-spoofing (DMARC/DKIM/SPF), and Business Email Compromise detection |
| Encrypted Backup | Encrypted off-site backup of client data with tested recovery — not just backup existence |
| Access Controls | Least-privilege access — staff can only access data they need for their role |
| Security Awareness Training | Regular phishing simulations and training — especially covering BEC and ATO impersonation |
| Patch Management | Timely patching of all devices — including accounting software updates |
Software Considerations for Accounting Firms
Queensland accounting firms typically operate across several software platforms that require specific IT configuration and security attention:
- MYOB, Xero, Reckon — cloud-based accounting platforms require MFA, regular access reviews, and integration security audits
- ATO Online Services for Agents / ATO Business Portal — requires myGovID with standard or strong identity strength; MFA is mandatory
- ASIC, AFCA, and ABA portals — access to regulatory portals must be controlled and monitored
- Microsoft 365 or Google Workspace — requires proper security configuration beyond default settings
- Client file management and document portals — must be encrypted and access-controlled

Frequently Asked Questions
What IT security requirements do accounting firms in Australia have?
Australian accounting firms must comply with the Privacy Act (Notifiable Data Breaches scheme), Tax Practitioners Board professional standards around data protection, and any cyber requirements imposed by their professional indemnity insurer. Practically, this means enforced MFA, encrypted backups, email security, and access controls at minimum. Aligning to the ASD's Essential Eight framework satisfies most of these obligations simultaneously.
What are the biggest cybersecurity risks for accounting firms?
The four biggest risks are: Business Email Compromise (fake payment redirection requests impersonating the firm or a client), phishing targeting ATO portal credentials, ransomware exploiting the value of client financial data during tax season, and insider threats from inadequate access controls. All four are addressable through standard managed IT and cybersecurity controls.

Do accounting firms in Queensland need to comply with the Essential Eight?
The Essential Eight is mandatory only for Australian Government entities. However, for private accounting firms, achieving Maturity Level 1 or 2 provides a practical baseline that satisfies Privacy Act obligations, TPB guidance, and most insurer requirements simultaneously. It is increasingly expected by larger business clients who want assurance their accountant handles data securely.
