A deferred tax liability occurs when taxable income is smaller than the income reported on the income statements. This is a result of the accounting difference of certain income and expense accounts. This is only a temporary difference. The most common reason behind deferred tax liability is the use of different depreciation methods for financial reporting and the IRS.
