In August 2025, the Tax Practitioners Board (TPB) cancelled the registration of a former partner and Research and Development claims specialist at PwC, imposing a 4-year ban from re-applying. Then, in March 2026, Chartered Accountants ANZ imposed a $7,567 costs order. Two separate regulatory bodies. One consistent finding: a fundamental failure of integrity and professional competence.
This was not a paperwork error. As the leader of PwC’s tax incentive group from 2016, he knew the rules. Regulators found he made false or misleading statements in Research and Development Tax Incentive (RDTI) applications lodged on behalf of clients, applications that did not meet eligibility requirements and could not be substantiated.
The conduct, as CA ANZ described it, was motivated by self-interest: specifically, increased revenues for PwC’s RDTI group. The public interest came second.
The Numbers That Tell the Story
The scale of the damage becomes clear when you look at what the ATO found after reviewing the claims this former PwC R&D Partner submitted:
- Over $11 million in cumulative tax shortfalls across affected clients
- More than $800,000 in penalties were imposed directly on those clients
- A four-year ban prohibiting re-applying as a registered tax agent
- Professional deregistration and public reputational damage across two peak bodies
These are not abstract figures. Behind each dollar is a business that trusted an adviser, submitted a claim in good faith, and then received an amended tax assessment, a repayment demand, and a penalty notice.
What Actually Went Wrong
Imagine you run a manufacturing business. You invest in a new production process, bring in technical consultants, and spend real money trying to solve a genuine engineering problem. Your R&D adviser, a partner at one of the Big Four firms, no less, tells you that the activity qualifies for the RDTI. You trust him. You lodge the claim. A year later, the ATO comes knocking.
That’s the reality for the businesses caught up in this case. The TPB found the RDTI applications lodged by this former PwC R&D Partner:
- Did not meet the eligibility requirements for the RDTI
- Could not be substantiated with proper evidence
- Lacked the basic scrutiny expected of a registered specialist
The result for clients? Amended tax returns. Repayment of offset amounts already received. Penalties and interest on top. Audit exposure costs time, money, and credibility.
CA ANZ made one particularly sobering observation: the claims were made without a proper inquiry into clients’ circumstances. Regulators found he knowingly made statements he knew, or should have known, were false.
The Part Nobody Talks About: Who Actually Pays
This is the part that gets lost in coverage of cases like this one. Everyone focuses on the adviser, the ban, the deregistration, the reputational collapse. And yes, for a former PwC R&D Partner’s seniority, those are serious consequences.
But he doesn’t write the cheque. His clients do.
Under Australian tax law, the entity that lodges the tax return carries the liability. The ATO assesses the claimant, not the adviser. So when a claim fails, whether through deliberate misconduct, careless application, or simply poor understanding of eligibility rules, the business that signed off on the return faces the financial consequences. This means that if tax practitioners act carelessly, it is the clients who end up paying.
You might be wondering whether there is any legal recourse against the adviser. There can be, through civil claims for professional negligence. But that is a long and expensive road, and it doesn’t stop the ATO from collecting what it says you owe with interest running the entire time.
This Is Not an Isolated Case
This matter sits within a broader pattern of scrutiny targeting R&D claims and the advisers who prepare them. In 2023, the TPB deregistered another former PwC tax partner, following the firm’s now-infamous Treasury leak scandal.
This case involved different conduct misuse of confidential government information, but the theme is consistent: senior advisers at major firms breaching the duties owed to clients, regulators, and the public.
The ATO has also made RDTI compliance a stated enforcement priority. Peter de Cure confirmed that, given recent issues in this area, R&D claims will be a compliance focus for 2025-26. If you have lodged RDTI claims in recent years with anyone, that’s a statement worth sitting with.
The R&D Tax Incentive program itself is legitimate and genuinely useful. The RDTI exists to encourage businesses to invest in innovations they might not otherwise pursue. Smaller companies in particular benefit from the reduced complexity the incentive provides. The problem is not the scheme. The problem is advisers who treat eligibility as flexible and documentation as optional.
3 Questions to Ask Your R&D Adviser
If you are currently claiming the RDTI or considering it, ask your adviser these questions before the next lodgement:
1. Can you walk me through the eligibility criteria my activities meet, specifically?
A competent adviser should be able to point to the specific legislative conditions your activities satisfy, not just assure you they do.
2. What documentation do you need from me, and why?
The ATO expects contemporaneous records that substantiate the technical uncertainty, experimental activities, and eligible expenditure. If your adviser doesn’t ask for much, that’s a red flag.
3. What’s your firm’s track record on RDTI claims?
Ask directly. Have any of their clients received amended assessments, been required to repay offsets, or faced penalties? The answer matters more than the credentials on the letterhead.
What Good Looks Like
Take a business owner who spent two years lodging RDTI claims through a national firm, received the offsets, and then went through an ATO review. The review found the technical documentation was incomplete. The offset had to be repaid, with interest. The firm that lodged the claim no longer exists in its original structure. The business owner is still dealing with the ATO.
That is the cost of working with an adviser who does not treat documentation and eligibility assessment as non-negotiable.
Contrast that with a specialist firm that builds the evidentiary file before a claim is lodged, not after. One that checks whether the technical activities genuinely meet the definition of experimental activity under the legislation. One that has never had a client face penalties, interest, or an offset repayment demand.
Pattens has operated in government grants and R&D Tax Incentive space for over 35 years with a 100% success rate on RDTI claims. No client has faced penalties or interest. No client has had to repay an offset. That record doesn’t come from luck. It comes from treating eligibility assessment and documentation as the foundation of every single claim, not an afterthought.
What This Case Should Change for You
The deregistration of a former PwC R&D Partner sends a clear message to the profession. Regulators are watching. The ATO has flagged R&D compliance as a priority area. And the TPB has shown it will act, including against senior practitioners at major firms.
But the lesson for you as a claimant is different. The regulatory action against the consultant does not change what his clients owe the ATO. It does not undo the amended assessments. It does not recover the $800,000 plus in penalties already imposed.
The only protection that actually works is choosing the right adviser before you lodge, not finding out their limitations after the ATO writes to you.
Brand name is not a substitute for genuine specialisation, proper process, and a verifiable track record.
Don’t Wait for the ATO to Find Out What Your Adviser Missed
If you are looking to claim the RDTI this year, have a direct conversation with a specialist who can show you their track record, not just quote it. Ask about their process, their documentation standards, and whether any of their clients have ever faced penalties or been asked to repay an offset.
