Nobody can really answer that question; there's not enough information in your post.
The amount you'll be RECEIVING isn't the relevant number to look at. What is taxable is the GAIN or LOSS realized on the stock sale, and that depends on your basis, which nobody here knows. Also, your holding period for the stock will affect the tax calculation. Generally gains from short term holdings, (owned one year or less), are taxed at "ordinary" income tax rates, while gains from long term holdings, (owned over a year), are taxed at favorable "long term capital gain rates" which range from 0% to 20%.
