Accounting & Tax
R&D Consulting
Maximising the R&D Tax Incentive with technical rigour and defensible documentation.

Accounting & Tax
Technically precise, commercially grounded tax and accounting advisory.
Overview
How we help.
The R&D Tax Incentive remains one of the most valuable innovation supports available to Australian businesses. But AusIndustry reviews and ATO scrutiny have intensified in recent years, and claims that cannot be defended are being reviewed, reduced or denied. Building defensible claims requires precise activity categorisation, proper technical documentation and a methodology that can withstand review.
Corson Fiske works with R&D claimants from project inception through to lodgement and review response. We advise on activity identification, documentation frameworks, expenditure calculation and interaction with the ATO and AusIndustry.
Our approach balances commercial optimisation with technical defensibility — because a large claim that cannot be sustained is not actually a claim at all.

- Core and supporting activity identification and documentation
- Technical narrative drafting and review

Client Situations
When clients engage us.
The issues that bring clients through our door tend to fall into familiar patterns.
A first R&D claim is being prepared
A new claimant needs to understand eligibility, documentation and methodology from the outset.
AusIndustry has commenced a review
A review of prior-year activities is underway and technical response is needed.
The ATO has raised expenditure questions
An audit or review of expenditure calculations requires defence.
A large or complex program needs assessment
A multi-year, multi-project R&D program needs a defensible framework.
The business is preparing for investment or sale
A transaction is approaching and the finance function, reporting and tax positions all need to be in order before diligence commences.
The finance team needs senior capability it does not have
The in-house team is competent at compliance but lacks the senior advisory capability the board expects on commercial matters.

Key Considerations
What clients need to know.
Engaging external advisors on any significant matter raises practical questions about scope, timing, cost and outcomes. We believe in being straightforward about each of these from the first conversation.
How engagements typically begin
Every engagement starts with a confidential initial conversation — usually 30 to 60 minutes — in which we listen to the situation, ask the questions needed to understand it properly, and share a view on whether and how we can help. There is no charge for this conversation and no obligation to proceed.
How we scope and price work
We prefer fixed-fee or capped-fee arrangements wherever the scope allows. Where the scope is genuinely uncertain — as in contested matters — we agree hourly rates upfront and provide regular fee updates against defined phases. We do not bill for internal discussions, file opening or routine administration.
Who you will work with
Every engagement is led by a partner with direct experience in the matter type. That partner remains your primary point of contact throughout. Specialist colleagues join the team where their expertise is required, but you will never be passed from person to person or find the partner you hired is no longer on the file.
How we handle confidentiality and privilege
All engagements are subject to strict confidentiality. Where legal advice is being delivered, it is provided through our incorporated legal practice and attracts legal professional privilege. We take document security, information handling and communications discipline seriously on every matter.
