Final answer:
South, Inc.'s deferred tax liability account balance at the end of year 2 is $6,300, after accounting for the year-over-year changes in the depreciation differences between book and tax purposes at a 21% tax rate.
Step-by-step explanation:
To calculate South’s balance in its deferred tax liability account at the end of year 2, we need to take into account the changes due to depreciation differences between book accounting and tax accounting, as well as the previous year’s deferred tax liability balance.
In year 1, the tax depreciation exceeded the book depreciation by $50,000. At a 21% tax rate, this results in a deferred tax liability of $10,500 (21% of $50,000), which matches the provided end-of-year 1 balance.
In year 2, the book depreciation exceeds the tax depreciation by $20,000. This reverses some of the liability created in year 1 by an amount of $4,200 (21% of $20,000).
Therefore, to find the ending deferred tax liability balance in year 2, we subtract the $4,200 from the beginning balance of $10,500 created in year 1. That gives us a new ending balance of $6,300 at the end of year 2 ($10,500 - $4,200).
