Which of the following causes a temporary difference between taxable and pretax accounting income

Numerous items create differences between accounting profit and taxable income. These differences can be divided into two types.

Permanent differences do not cause deferred tax liabilities or assets. These occur if a revenue or expense item:

  • is recognized for tax reporting but never for financial reporting, or
  • is recognized for financial reporting but never for tax reporting.

Therefore, permanent differences result from revenues and expenses that are reportable on either tax returns or in financial statements but not both. Permanent differences arise because the tax code excludes certain revenues from taxation and limits the deductibility of certain expenses.

  • In the U.S., for example, interest income on tax-exempt bonds, premiums paid on officer's life insurance, and amortization of goodwill (in some cases) are included in financial statements but are never reported on tax returns.
  • Similarly, certain dividends are not fully taxed, and tax or statutory depletion may exceed cost-based depletion reported in the financial statements.
  • Tax credits are another type of permanent difference. Such credits directly reduce taxes payable and are different from tax deductions that reduce taxable income.

These differences are permanent because they will not reverse in future periods.

No deferred tax consequences are recognized for permanent differences; however, they result in a difference between the effective tax rate and the statutory tax rate that should be considered in the analysis of effective tax rates.

Example

A company owns a $50,000 municipal bond with a 4% coupon and has an effective tax rate of 50% and a statutory tax rate of 40%. Calculate the deferred tax created by this bond.

Solution

The bond does not result in deferred tax, as the difference it causes is a permanent difference that will not reverse. As a result, no deferred tax is recognized.

Temporary differences result in deferred tax liabilities or assets. Different depreciation methods or estimates used in tax reporting and financial reporting are a common cause of temporary differences.

There are two categories of temporary differences.

Taxable Temporary Differences (TTD)

  • These will result in taxable amounts when an asset is recovered or a liability is settled.
  • Hence, these result in deferred tax liabilities. This means the company will pay more tax in the future.

Items that give rise to taxable temporary differences are:

  • Receivables resulting from sales.
  • Prepaid expenses.
  • Tax depreciation rates > accounting rates.
  • Development costs capitalized and amortized.

Deductible Temporary Differences (DTD)

  • These will result in deductible amounts when an asset is recovered or a liability is settled.
  • Hence, these result in deferred tax assets. This means the company will pay less tax in the future.

Items that give rise to deductible temporary differences are:

  • Accrued expenses.
  • Unearned revenue.
  • Tax depreciation rates < accounting rates.
  • Tax losses.

What are Permanent/Temporary Differences in Tax Accounting?

As described in CFI’s income tax overview, the difference in accounting for taxes between financial statements and tax returns creates a permanent and temporary differences in tax expenses on the income statement. The financial statements will arrive at a tax expense, but the actual tax payable will come from the tax return. This guide will explore the impact of these permanent and temporary differences in tax accounting.

Which of the following causes a temporary difference between taxable and pretax accounting income

What is a permanent difference in tax expense?

A permanent difference is the difference between the tax expense and tax payable caused by an item that does not reverse over time. In other words, it is the difference between financial accounting and tax accounting that is never eliminated. An example of a permanent difference is a company incurring a fine. Tax codes rarely ever allow a deduction in the event of a fine, but fines are often deducted from income in book accounting.

A permanent difference will cause a difference between the statutory tax rate and the effective tax rate. Also, because the permanent difference will never be eliminated, this tax difference does not generate deferred taxes, as in the case of temporary differences.

What is a temporary difference in tax expense?

Temporary differences are differences between pretax book income and taxable income that will eventually reverse itself or be eliminated. To put this another way, transactions that create temporary differences are recognized by both financial accounting and accounting for tax purposes, but are recognized at different times. This is why temporary differences are also known as timing differences.

An example of a timing difference is rent income. Accrual accounting will only allow revenue to be recorded when it is earned, but if a company receives an advance payment of rental income, it must report this under taxable income on its tax return.

As such, this revenue will be recorded on the tax return but not the book income. This creates a timing difference in this period. At a future period when the rental revenue is finally earned, the company will record that revenue under book income but not on its tax return, thereby reversing and eliminating the initial difference.

What effect do these differences have in tax accounting?

A permanent difference will never be reversed, and as such, will only have an impact in the period it occurs. Often, the only impact is that the effective tax rate on the books will be higher or lower than the effective tax rate on the company’s tax return.

A temporary difference, however, creates a more complex effect on a company’s accounting. If a temporary difference causes pretax book income to be higher than actual taxable income, then a deferred tax liability is created. This is because the company has now earned more revenue in its book than it has recorded on its tax returns.

The company knows that this will eventually have to reverse, and the company will have higher revenues and, thus, higher taxes on its tax returns at a future period. Transitively, having lower book income than tax income will result in the creation of a deferred tax asset.
