<prompt> Human: My company was recently acquired. Before the acquisition I purchased about 5k of vested ISOs. After the acquisition was complete I received a payment from those stocks of about 25k. They were subject to a disqualifying disposition, so I am expecting to pay federal and state taxes when I file for 2013.The remaining unvested options were converted to ISOs under the same terms for the acquiring company. I will have about 20 shares of stock vest every month for the next 30 months. Currently the shares are valued at about 100 share, and my strike is 20 share, leaving a spread of 80share 1600 gainmonth. Im curious if this sort of gain 3200 this year, 19kyr for the next 2 years will add enough to my AMT obligations, or if I can safely exercise and hold onto them for a year to benefit from the long-term capital gains taxes.Ive also been granted an additional 250k in RSUs which will vest over the next 4 years. I am expecting to just sell these immediately as they vest, so Ill just count these as ordinary income. Question about that though: Are RSUs also subject to FICA? I believe they are but Im not positive.Other information: 140kyr salary Maxed 401k pre-tax transit HSAtl;dr 1 Will a gain of 20kyr from ISOs be enough to worry about AMT, given a relatively high income? Should I talk to a professional?2 What should I do with 25k for a few months, knowing I will owe around 10k of it for taxes? Is a savings account the best choice given the low amount of time?  <response>: You raise some very complicated issues here. Talk to a qualified tax professional. I wouldnt trust any information from Reddit on an issues this convoluted.
