Fiscal drag is a constant pressure on taxpayers' wallets.

Are you paying more tax, but no better off?

Fiscal drag, or bracket creep, is the process by which taxpayers move up through the marginal tax bands as they get pay increases, and end up paying higher proportions of their income in tax, even if they have only kept pace with inflation.

It is something that the Australian opposition has said this week it wants to tackle by indexing tax bands to inflation.

Opposition leader Angus Taylor has been reported as saying it could deliver workers an extra A$1000 a year, four years into the policy but would cost the government about A$22 billion.
