As discussed in our December 16, 2010, blog article, the IRS issued final regulations in 2009 under Section 6039 of the Internal Revenue Code (the “Code”) that require employers to annually furnish each employee who exercised incentive stock options (“ISOs”) or sold or otherwise transferred shares acquired under an employee stock purchase plan (“ESPP”) during a year with a detailed information statement by January 31 of the following year. In addition, employers must generally file an information return with the IRS by February 28 of the following year, or by March 31 for employers filing electronically. These due dates are delayed until the next business day if they otherwise fall on a weekend.
