Unfortunately, there’s no straight answer to this. It will depend on where you are located, where the acquirer is located, what industry you are in, the details of you own personal tax situation, and a myriad of other factors. You’ll want to consult with a CPA that specializes in startup taxation, as any advisory services will be tailored to your unique situation.
