R&D Tax Incentive: FY2024-25 Registration Deadline Is 30 April 2026

If your company conducted R&D activities between 1 July 2024 and 30 June 2025, you have until 30 April 2026 to register them with the Department of Industry, Science and Resources (DISR). Miss that date and you lose the claim entirely. There are no extensions.

Prime Partners R&D Tax Incentive Services

Our specialist R&D advisory team operates under Prime Innovation, our innovation and government incentives division. The team comprises chartered accountants with hands-on R&D claim experience across software, manufacturing, agriculture and professional services.

We charge a fixed fee for R&D claim preparation. No percentage of your refund, no success fees. The ATO has publicly flagged contingency-fee R&D advisers as a compliance risk, and you want an adviser whose fee stays the same regardless of claim size.

If you have not registered your FY2024-25 R&D activities yet, do not wait. The deadline is less than three weeks away.

The 30 April 2026 Deadline

The R&D Tax Incentive is a two-step process, and this trips people up. Most businesses know they need to claim the offset in their company tax return. What many miss is that registration with DISR must happen first, with its own earlier, hard deadline.

Step 1: Register with DISR (Deadline: 30 April 2026)

You must register through the DISR customer portal within 10 months of income year end. For standard 30 June year-end companies, the FY2024-25 deadline is 30 April 2026.

Registration requires you to describe each core R&D activity and supporting activities, the technical uncertainty you were resolving, the new knowledge you were pursuing, and why a competent professional could not have determined the outcome in advance.

Once processed, DISR issues a registration number. Without it, your accountant cannot complete the R&D schedule in your tax return.

Step 2: Claim in Your Company Tax Return

After registration, include the R&D Tax Incentive Schedule in your company tax return. For most businesses using a tax agent, this is not due until late 2026. But Step 1 must be done by 30 April.

There Are No Extensions

The 10-month deadline is legislated. DISR and the ATO have zero discretion to accept late registrations, regardless of reason. Miss 30 April 2026 and your FY2024-25 R&D claim is gone.

What Is the R&D Tax Incentive Worth?

Companies With Turnover Under $20 Million

The refundable offset is 43.5% of eligible R&D expenditure (the 25% company tax rate plus an 18.5% premium). If your company is in a loss position, this comes back as a cash refund from the ATO.

Eligible R&D Spend Profitable Company Company in Losses
$100,000 $18,500 $43,500
$250,000 $46,250 $108,750
$500,000 $92,500 $217,500
$1,000,000 $185,000 $435,000
$2,000,000 $370,000 $870,000

The refundable offset is capped at $4 million per year. Excess becomes a non-refundable offset that carries forward. Clinical trial expenditure is exempt from this cap.

Companies With Turnover of $20 Million or More

The non-refundable offset is tiered based on R&D intensity:

  • R&D intensity up to 2%: Company tax rate + 8.5% premium
  • R&D intensity above 2%: Company tax rate + 16.5% premium

Eligible expenditure is capped at $150 million per income year.

Key Dates for FY2024-25 R&D Claims

30 June 2025 FY2024-25 income year ends
1 July 2025 DISR registration portal opens for FY2024-25

The Compliance Environment Has Changed

Both the ATO and DISR have significantly ramped up compliance activity. In the 2022-23 income year, 12,956 companies claimed a combined $16.2 billion in R&D expenditure. A programme that size attracts enforcement resources.

From 1 July 2025, DISR is applying a one-strike policy. If a single eligibility requirement is not met during a review, the entire activity gets rejected. No informal education, no risk assessment. Formal examinations only.

The registration form is also changing. From August 2025, the technical description section expands from 1,000 to 4,000 characters, with a layout that tracks more closely to the legislation.

Five Mistakes That Cost Businesses Their R&D Claims

1. Missing the Registration Deadline

Every year, businesses that did genuine R&D lose their entire claim because nobody lodged the registration in time.

2. Weak Activity Descriptions

“We developed new software” will not survive a DISR review. Your description needs to pin down the specific technical uncertainty, what you tried, and why a competent professional could not have determined the outcome in advance.

3. Overstating Expenditure

Claiming 100% of an employee’s salary when they spent 30% of their time on R&D is a red flag. The ATO wants a reasonable basis for splitting costs. Timesheets, project management records, time-tracking tools all work.

4. No Contemporaneous Documentation

Your records need to be from the time the R&D was actually happening. DISR assessors check metadata, timestamps and document properties to verify authenticity.

5. Confusing Registration With the Tax Claim

Two separate steps. DISR registration first, then the R&D schedule in your company tax return. We have seen businesses register on time but forget the R&D schedule when they lodge their return.
