Rates of R&D tax incentive offset

Work out the R&D tax incentive offset rate for your eligible entity.

Last updated 21 May 2024

The research and development (R&D) tax incentive provides targeted tax offsets designed to encourage more companies to engage in R&D. The incentive has 2 core components. For income years starting on or after 1 July 2021, entities engaged in R&D may be entitled to:

  • a refundable tax offset equal to the entity’s company tax rate plus an 18.5% premium for eligible entities with an aggregated turnover of less than $20 million per annum, provided they are not controlled by income tax-exempt entities
  • a non-refundable tax offset for all other eligible entities equal to the entity’s company tax rate plus a two-tiered premium determined on the notional R&D expenditure as a proportion of total expenditure for the income year. The new rates will be the company tax rate plus
    • 8.5% for R&D expenditure up to 2% of total expenditure
    • 16.5% for R&D expenditure above 2% of total expenditure.

Entities may be able to carry forward unused offset amounts to future income years. To find out more, see Refundable and non–refundable offsets.

The rate of the R&D tax offset is reduced to the company tax rate for that portion of an entity's notional R&D deductions that exceeds $150 million for an income year. If you previously claimed a concession you can transition from the R&D concession to the R&D tax incentive.
