Have a Tax Question? Ask a Tax Expert
Hi Tim. My name is ***** ***** I will be happy to help you.
There are many things that could be affected by the stock option, like your tax brackets, certain credits, deductions and such. Did you prepare your taxes yourself or paid somebody do it for you?
The best ways would be to use the original software, simply remove the stock option and compare the difference in refund/balance due. If you exercised your option immediately, most of the income was reported on your W2. If you didn't sell it immediately, than some of the option was reported as capital gains and some as ordinary income. You would have to remove the additional amount from your W2 and the capital gains, if any to see the difference the stock option made.
Your preparer, if she has access to your return should be able to do the analyses. Without reviewing your return there's no way to tell how the stock option affected your balance due/refund.
