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.
An average tax rate is the ratio of the total amount of taxes paid to the total tax base (taxable income or spending), expressed as a percentage. 1  Let t {\displaystyle t} be the total tax liability. 2  Let i {\displaystyle i} be the total tax base.
