And there is nothing to worry here actually, for even if you have set your hard disk to turn off after say 5 mins, if there is some background maintenance task being carried out, it will not shut down â but instead the system will reset the hard diskâs idle timer.
The Average Tax Rate Definition. The average tax rate in the United States varies depending on the amount of income to which it's applied. An average tax rate as it applies to income tax may be defined as the percentage of income owed as taxes or, as Fair Tax defines the term, as the ratio of taxes paid to taxable income. In mathematical terms, divide the total tax liability by total taxable income to get the average tax rate.
A taxpayerâs average tax rate (or effective tax rate) is the share of income that he or she pays in taxes. By contrast, a taxpayerâs marginal tax rate is the tax rate imposed on his or her last dollar of income.Taxpayersâ average tax rates are lower â usually much lower â than their marginal rates.or example, the first portion of any taxpayerâs taxable income is taxed at a 10 percent rate, the next portion is taxed at a 15 percent rate, and so on, up to a top marginal rate of 39.6 percent. As an example, the graph below shows a married couple with two children earning a combined salary of $110,000.
