An R&D entity may be entitled to a tax offset for R&D activities. The tax offset may be a refundable tax offset if the R&D entity's aggregated turnover is less than $20 million.

To be entitled to the tax offset, the R&D entity needs one or more notional deductions under this Division.

There are 2 main kinds of notional deductions. One is for expenditure on R&D activities. The other is for the decline in value of tangible depreciating assets used for R&D activities.
