Answer:
$12,600
Explanation:
Excess tax depreciation 20X1 = 100,000 - 40,000
Excess tax depreciation 20X1 = $60,000
Tax rate = 21%
Ending balance of deferred taxes payable = Excess tax depreciation 20X1 * Tax rate
Ending balance of deferred taxes payable = $60,000*21%
Ending balance of deferred taxes payable = $12,600
So, the ending balance of deferred taxes payable as of December 31, 20X1 is $12,600.
