3.2 Notes on the estimates
Unless otherwise indicated, tax expenditure estimates are calculated on an individual basis and do not take account of potential overlaps with other tax expenditures.
Tax expenditure estimates are separated into estimates (for historical years) and projections (for future years). The estimates for 2009-10 are preliminary and subject to revision upon receipt of further tax data.
The tax expenditure estimates are prepared on the same revenue recognition basis as the budget estimates. Further detail on the revenue recognition basis used in the TES is provided in Chapter 2.
