Excerpt from Policy Forum: Cognitive Bias as a Factor in Determining the Efficiency of Sliding Scales:

In tax law, sharp lines occur where a minimal change in a taxpayer’s circumstances results in significantly different legal treatment. Sharp-line tests are criticized because they encourage taxpayers to alter their optimal behaviour for purely tax reasons, thereby producing deadweight loss. The most obvious alternatives to sharp-line tests are sliding scales, which operate by imposing tax proportionately on the basis of where taxpayers fall along a continuum.
