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.
The marginal tax rate is the tax that applies to the next increment of income or deduction. The average tax rate represents a taxpayer's average level of taxation on each dollar of taxable income. The effective tax rate represents the taxpayer's average rate of taxation on each dollar of total income (taxable and nontaxable income).
