input: [Term] Bracket creep [Definition] 
output: Fiscal drag refers to when excessive taxation or a lack of spending by the government puts a dampener on the economy. Bracket creep is a form of fiscal drag that occurs when tax rates do not keep up with wage increases in the economy, pushing wages up to a higher bracket, and resulting in the government taking more tax revenue. Tax brackets are designed to be indexed to account for increases in inflation, however the indexes are usually set manually, and leaving them stationary while wages grow allows the government to increase the amount of revenue it takes from taxpayers without raising taxes. Warnings from accounting firms KPMG and PwC have fuelled speculation that the government is planning on letting bracket creep do some of the heavy lifting when it comes to recovering revenue.
