Interested in expanding your investment portfolio while limiting your tax burden? Purchase qualified small business stock (QSBS) before the end of this year. There is no tax on gain from the sale of such stock if it is (1) purchased after September 27, 2010 and before January 1, 2011, and (2) held for more than five years. In addition, such sales won't cause AMT preference problems. To qualify for these breaks, the stock must be issued by a regular (C) corporation with total gross assets of $50 million or less, and a number of other technical requirements must be met. Our office can fill you in on the details.
