What Is a Comfort Letter?
A comfort letter is an independent statement from an R&D tax advisor confirming that your activities and projected expenditure meet the ATO’s criteria for the R&D Tax Incentive.
It’s typically required when you’re applying for a loan against your upcoming R&D refund—giving lenders the confidence that your claim is on solid ground.
Without a comfort letter, lenders might hesitate or add extra conditions due to the perceived risk. By providing this document, you’re offering transparency and giving lenders the confidence they need to approve financing based on your anticipated refund.

Do I need a Comfort Letter?
Securing R&D lending can seem confusing.
You’ll likely need a comfort letter if:
You’re securing an R&D loan before receiving your tax refund
A lender, accountant, or funding partner has requested third-party validation
You want assurance before committing to a claim or finance arrangement
This is where we come in. Our expert team specialises in guiding clients through all stages of the R&D Tax Incentive application process.

What's included? 5-Step-Process
Securing a comfort letter means more than just ticking boxes. We take a detailed look at your R&D claim to make sure it meets the requirements of all relevant bodies so you don’t need to worry. Here’s how we do it:
R&D Activity Review
We begin by reviewing your core and supporting R&D activities to ensure they align with AusIndustry’s criteria. Our focus is on confirming that the work you’re claiming is genuinely experimental and eligible under the legislation.
Review of R&D Expenditure
Next, we assess the costs you’ve allocated to R&D. We make sure they’re directly tied to eligible activities—not just general operating costs—and meet the ATO’s substantiation requirements.
Supporting Evidence
If we need more detail, we’ll request any additional documents—like timesheets, technical records, or project notes—that help support your claim. This ensures the final position is well-backed.
Documentation Check
We then analyse the evidence provided, reviewing how time, staff, and resources were allocated to R&D. We’re looking for strong, contemporaneous documentation that reinforces the claim.
Comfort Letter Issued
Once everything checks out, we prepare and issue the comfort letter. It includes a clear summary of our findings and confirms that your claim has been reviewed against the relevant legislation—giving lenders the confidence to proceed.
You’ll barely need to lift a finger.
