Senators Levin (D. Mich) and Brown (D. Ohio) have introduced the Ending Excessive Corporate Deductions for Stock Options Act, legislation that would limit the amount a corporation can deduct in connection with the exercise of compensatory stock options to the amount shown as an expense for the options in its financial statements. Similar proposals have been made in the past without garnering wide support.

Comment: Although it seems superficially logical that the tax deduction should not exceed the accounting expense, these figures differ because their purposes differ. The accounting expense relates to the company’s cost of providing this benefit, which in turn is based on the value of the option when granted. The tax deduction relates to the value of the benefit received by (and taxed to) the option holder, which is based on the bargain element of the option when exercised. A mismatch between these numbers is a normal consequence of ups and downs in stock prices and does not indicate the company has understated its accounting expense or claimed an excessive deduction.
