As we reach the end of 2013, revisiting the Qualified Small Business Stock (QSBS) provisions under both federal and California tax law should be a top priority. For federal purposes, a significantly advantageous provision is set to expire on December 31. Earlier in 2013 passage of the American Taxpayer Relief Act of 2012 extended the favorable gain exclusion provisions for QSBS retroactively through the end of 2013 for regular and alternative minimum tax purposes.
