What Is TASA and Why Is It Changing How We Work?

Understanding the New TASA Code of Conduct 

There’s been a quiet shift happening in the tax profession, and you might start to notice some differences in how we work with you. If we’ve asked for more documentation than usual this year, or been a little firmer about what’s needed, here’s why

What is TASA?

TASA stands for the Tax Agent Services Act. It’s the framework that governs how tax agents and accountants operate in Australia. Part of that framework is the Code of Professional Conduct, which outlines how we work, what’s expected of us, and how we protect our clients.


The Code covers things like:


  • Acting with honesty and integrity

  • Working with competence and care

  • Maintaining confidentiality

  • Keeping our knowledge up to date

  • Complying with tax laws

What’s changing?

The Code itself hasn’t dramatically changed, but the way it’s being enforced has. The Tax Practitioners Board is lifting expectations and we’re responding by tightening our internal processes.


You’ll likely notice a few shifts:


  • More requests for source documents and evidence

  • More follow-up questions if something doesn’t quite add up

  • More transparency around what we’re checking and why

  • Clearer expectations about what’s required for us to act on your behalf

Why it matters

We’re not being difficult, we’re doing our job properly. And that protects you.


When we submit a return or lodge something on your behalf, we’re also signing off that we’ve taken reasonable care and verified the information. If we can’t do that, we’re not allowed to proceed.


The more accurate and well-supported your records are, the less likely you are to face issues with the ATO. And if something is ever reviewed, you’ll be in a much stronger position with clean documentation and a clear paper trail.


What you might be asked for

Depending on your situation, we may ask you for:


  • Full loan statements for investment properties (including redraws)

  • Valid logbooks and odometer readings for vehicles

  • Broker summaries or CGT reports for investment activity

  • Clear apportionments for private use or mixed-purpose assets

  • Updated details on trusts, directors, or business structure

We’ll always explain what we need and why. But we won’t be able to cut corners, even if it feels like a small thing.


The bottom line

This is about doing things properly so you’re protected, and we’re compliant.


We’re committed to making things easier for you, but we’re also committed to doing things right. If we’re asking more of you, it’s because the standards we’re held to have changed, and that’s not a bad thing.


If you have questions about what we need or how we work under the new Code, just reach out. We’re happy to walk you through it.

Many businesses operate by only looking at historical data from their bookkeeper or accountant. This tells you where you’ve been, but offers little guidance on where you’re going or how to navigate the road ahead. A virtual CFO, or vCFO, acts as your financial co-pilot, focusing on the future. They go beyond basic compliance and tax lodgements to provide the strategic direction needed to make informed decisions that drive growth. The Strategic Partner Your Business Is Missing While an accountant is essential for maintaining accurate records and meeting ATO obligations, a vCFO’s role is fundamentally different—it's about shaping the future financial health of your business. They analyse your financial data to identify opportunities and flag risks before they become significant issues. For Australian businesses, this strategic partnership delivers clear advantages: Actionable Insights: They translate complex financial reports into plain English. Instead of just seeing a profit figure, you’ll understand which products are most profitable, where costs are increasing, and what specific actions you can take to improve performance. Improved Decision-Making: Key decisions—such as hiring new staff, investing in equipment, or adjusting pricing—are no longer based on gut feelings. A vCFO supports these moves with solid data and financial modelling. Sustainable Growth: They help you manage cash flow, position your business for funding, and build a resilient financial foundation for long-term success. A virtual CFO doesn't just manage your finances; they manage your financial future. Their primary goal is to use financial intelligence to help you build a more profitable and stable business, turning historical data into a roadmap for growth. Building Your Financial Roadmap Many business owners seek a vCFO when facing a specific challenge, such as inconsistent cash flow, shrinking profit margins, or preparing the business for sale. A vCFO addresses these issues by creating financial clarity and developing a clear plan. If you want to dive deeper into this process, our guide on crafting a strategic plan as your roadmap to business growth is a great resource. By building accurate forecasts and tracking relevant key performance indicators (KPIs), they provide the visibility needed to navigate economic challenges and seize opportunities. This proactive approach ensures your business is always prepared for what’s next. What a Virtual CFO Actually Does for Your Business Many business owners view finance through two lenses: a bookkeeper for daily transactions and an accountant for tax compliance. Both are critical, but a virtual chief financial officer (vCFO) operates on a strategic level. They are focused on shaping what happens next quarter, next year, and five years from now. A vCFO acts as your strategic guide, translating financial data into clear, actionable intelligence. It’s about moving beyond simply reporting the numbers to explaining what those numbers mean for your future. Moving Beyond Reporting to Strategic Insight A traditional accountant will prepare a profit and loss statement that tells you if you made money. A vCFO takes this further by analysing that P&L to pinpoint exactly which products or services drive your profits and which ones are underperforming. This analysis leads to crucial strategic questions. Should you invest more in your most profitable offering? Is it time to discontinue a low-margin service? A vCFO provides the data-backed confidence to make these decisions. Their forward-looking role includes: Strategic Financial Planning: They help build a long-term financial roadmap aligned with your business goals, ensuring you have the resources to achieve them. Cash Flow Optimisation: This involves proactively managing cash. A vCFO creates detailed cash flow forecasts to identify potential shortfalls months in advance, helping you avoid liquidity issues. Insightful Forecasting and Budgeting: They build dynamic financial models to simulate scenarios. For instance, they can project the financial impact of hiring new staff or investing in major equipment. A simple way to differentiate the roles: A bookkeeper records the game's score. An accountant ensures the score is reported correctly. A virtual CFO is the coach, analysing the play, calling shots, and creating a strategy to win.
