Quick answer: Yes — a South Australian Seed-Start grant does not stop you claiming the federal R&D Tax Incentive; they are separate programs from separate governments. The catch is overlap: if the grant reimburses the same R&D expenditure you claim, a federal clawback adjustment applies so you don't receive both benefits on the same dollars. Plan the split before you spend, not after.
25 June 2026 — the 2026–27 Federal Budget announced R&DTI changes scheduled to start 1 July 2028; this article describes the current rules unless stated otherwise.
It is the question we hear most often across the Lot Fourteen tables and Adelaide founder Slack channels: "We landed a Seed-Start grant — does that knock us out of the R&D Tax Incentive?"
In most cases, receiving a South Australian Seed-Start grant does not automatically prevent a company from accessing the federal R&D Tax Incentive. A South Australian state grant and the federal R&D Tax Incentive (R&DTI) are two different programs from two different governments, and you can generally access both. The detail that trips people up is what happens when a grant pays for the same R&D expenditure you later claim. That overlap can trigger a federal clawback adjustment — and the way to keep your numbers clean is to plan for it before you spend, not after.
This is general information from a Registered Research Service Provider. The mechanics below are set out by the ATO, business.gov.au and the SA Government; the treatment of your specific grant depends on its terms and your circumstances, so you should self-assess and seek your own advice.
State grants and the federal R&DTI are not the same thing
It is worth being precise, because conflating the two causes most of the confusion.
The R&D Tax Incentive is a federal program, jointly administered by the ATO and the Department of Industry (business.gov.au). For companies under $20 million aggregated turnover, the refundable offset is the company tax rate + 18.5 percentage points — 43.5% for a 25% base-rate entity — on eligible R&D expenditure.
South Australian grants are state programs, run by the SA Department of State Development. These include the Research & Innovation Fund / Seed-Start stream, the Research Commercialisation & Startup Fund (RCSF), the Business Growth Fund, and the newly announced $50 million R&D Productivity Fund flagged in the 2026 SA Budget. Seed-Start itself provides matched funding for SA-based companies with average annual revenue under $2 million — Seed grants of up to $100,000 (2:1 government matching) and Start grants of up to $500,000 (1:1 matching).
A state grant is not "the R&DTI", and the R&DTI is not a grant — they are funded and assessed separately. (One genuinely federal initiative founders sometimes lump in with state support is Austrade's Landing Pads program; despite the local interest, it sits at the Commonwealth level, not with SA.)
For the newer announcements — the $50M R&D Productivity Fund and any 2026 SA Budget measures — treat them as announced rather than open. Check the published guidelines for eligibility, opening dates and how funding is paid before assuming you qualify.
How clawback works when a grant funds the same R&D
You can hold a state grant and claim the R&DTI on the same project. What changes is how much net benefit you keep when grant money has effectively reimbursed your R&D costs.
The ATO treats certain government payments as a recoupment — broadly, where a payment is received as a recoupment of, or required to be spent on, the R&D expenditure you are claiming. When that link exists, a clawback adjustment applies so you don't benefit twice on the same dollars: the grant covering a cost and the full offset applying to that same cost.
Importantly, clawback does not claw back your grant, and it does not cut your offset line directly. Instead, the ATO adds an extra amount to your assessable income in the year you claim — broadly the offset-rate component applied to the grant-funded portion of your R&D spend.The grant is not directly clawed back, and the R&D Tax Incentive offset is not reduced at source. Instead, where a government grant is treated as a recoupment of eligible R&D expenditure, an assessable income adjustment may apply under the R&DTI clawback rules for the relevant amount.
An Adelaide worked example
Suppose an Adelaide software company spends $300,000 on eligible R&D this year, and a Seed-Start grant reimburses $100,000 of that specific expenditure.
The company can still bring the full $300,000 into its R&DTI calculation.
Because $100,000 was received as a recoupment of that R&D spend, a clawback adjustment applies to that $100,000.
The adjustment adds an extra amount to assessable income — broadly the offset-rate component on the grant-funded portion — rather than reducing the grant or the offset itself.
These figures are illustrative and rounded to show the mechanic only; they are not a calculation of your benefit. Your actual position depends on your offset rate, aggregated turnover, tax position and the grant's terms. The point stands: grant plus R&DTI usually leaves an SA founder better off than either alone — clawback removes the double-up, not the upside.
How to structure both claims cleanly
Most clawback headaches are really record-keeping headaches. The cleanest claims keep grant-funded and tax-claimed dollars distinguishable from day one.
Separate funding sources in your ledger. Tag which costs were met by Seed-Start, RCSF or other grant money versus your own funds, so the recouped portion is obvious at year end.
Read the grant agreement with the R&DTI in mind. Whether the funding is tied to specific R&D expenditure (more likely a recoupment) or is general support signals whether clawback is in play.
Map grant milestones to registered R&D activities, so deliverables line up with the experimental work you claim.
Document the technical work regardless of who paid. R&DTI eligibility rests on the experimental nature of the activity, not its funding source.
This is where a Registered Research Service Provider earns its place — not by giving tax advice, but by defining, structuring and evidencing the research so the expenditure mapping is sound. We work alongside your tax agent: they handle the offset and clawback calculation; we make the underlying R&D defensible.
There's a second RSP advantage worth knowing. Registered Research Service Providers (RSPs) may assist in structuring, documenting, and evidencing R&D activities for R&D Tax Incentive purposes, particularly for early-stage companies with limited internal capability. (Using an RSP does not guarantee eligibility — you still self-assess.) It also remains the route to qualify if the proposed $50,000 minimum from 2028 becomes law. Those 2028 reforms are proposed, not law today and shouldn't drive current-year decisions; our note on claiming R&D under $20,000 explains the threshold mechanics, and the R&D Tax Incentive in Adelaide page covers the local picture.

Frequently asked questions
Q: Can I claim a Seed-Start or RCSF grant and the R&D Tax Incentive? A: Generally yes. A South Australian state grant does not disqualify your R&D activities or expenditure from the federal R&DTI. But if the grant is received as a recoupment of the same R&D expenditure you claim, a clawback adjustment applies so you don't benefit twice on those dollars. Self-assess against ATO guidance and seek your own advice.
Q: Do South Australian grants trigger R&D clawback? A: They can — when the grant funds or reimburses the specific R&D expenditure you also claim under the R&DTI. Clawback adds an amount to your assessable income on the grant-funded portion; it does not reduce the grant or the offset line directly. General or untied support is less likely to be treated as a recoupment, but the grant's terms decide.
Q: Which SA grants interact with the federal R&DTI? A: Any state grant that reimburses or is required to be spent on R&D expenditure you claim can interact via clawback — for example Seed-Start, the RCSF or the Business Growth Fund where the funding is tied to that spend. The newly announced $50M R&D Productivity Fund should be checked against its published guidelines. The interaction is about funding the same R&D, not the grant's name.
Q: How do Adelaide startups combine state grants and the R&DTI? A: Keep grant-funded and self-funded R&D costs clearly separated in your records, retain the grant agreement, map milestones to your registered R&D activities, and let your tax agent apply the clawback method. With a registered RSP, RSP-conducted eligible R&D activities can be claimed even where the usual $20,000 R&D expenditure threshold is not met, which helps small first-year claims — though using an RSP does not guarantee eligibility, so you still self-assess.
