Chapter 5.2® - Income Tax Provision or Expense? Differences between Taxable & Accounting Income (Permanent & Temporary Differences)
Provision or Expense?
It has been noted in common that companies show the income tax expense in the income statement as “provision for income taxes”.
The reason that companies use provision for the income tax expense is that when the company has loss for tax purposes, the income statement entry for income taxes may be a credit rather than debit.

The timing difference originates in the period in which it first enters the computation of either taxable income or accounting income, and reverses in the subsequent period when that item enters into the computation of the other measure. An item can either:
Let's consider an example. Revenue on a long-term contract may be recognized on a percentage-of-completion basis for accounting purposes. For the income tax purposes, the recognition of revenue can be delayed until the contract is completed, provided that the contract lasts no more than two years. The revenue recognized in the first year will enter into the determination of net income, thereby giving rise to an originating temporary difference. In the following year, after the contract has been completed, the revenue and related expenses will be included in taxable income
