Q: I am a founder of a company that is being acquired. My shares were fully vested in my company, but in the acquisition transaction I am receiving shares of the acquiring company that will be subject to certain vesting conditions. Do I need to file an 83(b) election?
A: Yes, you should file a Section 83(b) election. If you don’t, you could have income when your new shares vest–an outcome you would prefer to avoid.
