obinson Company had a net deferred tax liability of $34,000 at the beginning of the year, representing a net taxable temporary difference of $100,000 (taxed at 34 percent). During the year, Robinson reported pretax book income of $400,000. Included in the computation were favorable temporary differences of $50,000 and unfavorable temporary differences of $20,000. During the year, Congress reduced the corporate tax rate to 21 percent. Robinson's deferred income tax expense or benefit for the current year would be:

Robinson's deferred income tax expense or benefit for the current year would be $6,700

Explanation:

The computation of the deferred income tax expense or benefit for the current year is shown below:

= Deferred tax expense - adjustment of tax based on the tax rate

where,

Deferred tax expense = (Favorable temporary differences - unfavorable temporary differences) * corporate tax rate

= ($50,000 - $20,000) * 21%

= $6,300

And, the adjustment of tax equals to

= Net taxable temporary difference * (Tax rate - corporate tax rate)

= $100,000 * (34% - 21%)

= $13,000

Now put these values to the above formula

So, the value would equal to

= $6,300 - $13,000

= $6,700
