The accounting
basis is not the same — the Estimates are
on a cash
basis of accounting while the Budget is
on an accrual
basis; the coverage is not the same — with the exception of the Guaranteed Income Supplement, tax
expenditures are not included in the Estimates; and the Estimates are
on a
net basis,
netting off revenues against applicable spending, while the Budget is
on a gross
basis, recording such charges / fees as revenues.
