Unfortunately MBA costs cannot be deducted for income tax purposes. Doing an MBA is seen as a way of improving your income earning ability not as actually earning income. So for tax purposes it is seen as more of a capital investment and despite it being directly related to your employment it does not result in extra income.
I wish I had better news for you, if you could push your employer to pay these costs somehow, they could claim a tax deduction for a portion of the costs.
If you have any further questions, please feel free to ask away.
