Two documents, one direction — different dials

The Ambitious Australia review (released March 2026) recommended redesigning the R&D Tax Incentive. The 2026–27 Federal Budget (announced 12 May 2026) adopted a version of that redesign, proposed to apply to income years starting 1 July 2028. The direction is the same — reward genuine core, experimental R&D and better target young, fast-growing firms — but several settings were changed along the way.

Where the Budget went further — and where it pulled back

  • More inclusive of small projects. The review proposed lifting the project floor to $150,000; the Budget set it at $50,000 (and requires sub-$50,000 R&D to be done with a recognised research organisation).
  • A longer refundability runway. The review limited refundability to a firm's early years; the Budget extended eligibility to firms operating under ten years.
  • More conservative on structure. The review proposed removing the R&D intensity measure and the expenditure ceiling entirely. The Budget kept both — lowering the intensity threshold to 1.5% and lifting the cap to $200M rather than abolishing them.
  • Harder on supporting activities. The review proposed a deemed rate for supporting (non-core) activities. The Budget went further and removed eligibility for expenditure that only supports R&D.

What's settled — and what isn't

The Budget figures are the announced design. They are unlegislated, and detail can change through consultation and drafting before the 1 July 2028 start. Until then, the current rules continue to apply.

For companies and advisers, the practical takeaway is the same regardless of which dials move: the reformed regime weights core experimental activity more heavily, so the ability to characterise and evidence each activity — with records made at the time — is what carries the claim.
