Answer: c. differences in depreciation methods (accelerated vs. straight-line) for tax versus financial accounting purposes.
Step-by-step explanation:
A Deferred tax liability arises as a result of the tax authorities using a different accounting convention from the business. This leads to a situation where the company records more tax than the tax authorities do so the company will recognize the extra tax as a liability until it is paid.
The main cause of this is the difference in depreciation methods. The tax authorities use an accelerated method which would lead to a lower profit in early years which would translate to a lower tax. The company on the other hand would use straight line depreciation and calculate a higher tax. The difference is called the deferred tax liability.
