Answer: The capital structure change will be less beneficial
Step-by-step explanation:
The move would be less beneficial because the main advantage of Debt is that it is not Taxable. This means that having debt as a company gives you a sort of TAX SHIELD.
However, in the above scenario, the tax rate is due to decrease. This means that there is less of a reason to have a tax shield. It is therefore less beneficial to accrue more debts which can put the company in financial distress when there is no added benefit of a tax shield.
