How does 83b election work when paying fair market value at time of grant?
83(b) election requires you to pay the current taxes on the discount value. If the discount value is 0 - the taxes are also 0. Question arises - why would someone pay FMV for restricted stocks? That doesn't make sense. I would argue, as a devil's advocate, that the FMV is not really fair market value, since the restriction must have reduced the price you were willing to pay for the stocks. Otherwise why would you buy the stocks at full price - with strings attached that could easily cost you the whole amount you paid?
