How is the clawback adjustment calculated?

The clawback adjustment is extra income tax of 10% on both of the following:

  • the R&D expenditure and decline in value for which you claimed a notional deduction in relation to the recoupment
  • the expenditure and decline in value for which your affiliates and entities connected with you claimed a notional deduction in relation to the recoupment.

A cap applies to ensure the clawback adjustment cannot exceed the amount of a grant you received that, on a pro-rata basis, relates to the total expenditure on R&D activities and related decline in value. This means the benefit of the R&D tax incentive cannot be clawed back beyond the amount of the grant.


If an entity’s notional R&D deductions exceed $100 million for an income year, the amount of expenditure used in the calculation of the clawback adjustment may be reduced.

End of attention


Burgundy Bagasse Ltd conducts R&D activities in relation to a new machine that removes, shreds, crushes and bales grape vines. The activities for which they receive the R&D tax incentive include trials on a vineyard they use to produce table wine.

Burgundy Bagasse Ltd also receives a $500,000 reimbursement under a government vine-pull scheme for certain costs they incurred to remove those vines. Of this amount, $400,000 was for expenditure they notionally deducted under the R&D tax incentive.

Clawback of $40,000 (10% of $400,000), in the form of extra income tax, will apply in relation to the R&D expenditure that is reimbursed under the vine-pull scheme.
