IRS and Treasury extend due date for error reports disputing the preliminary calculation of the annual fee imposed on branded prescription pharmaceutical manufacturers and importers

Late on May 27, 2011, the IRS and Treasury issued Notice 2011-46 extending the postmark date for error reports disputing the preliminary calculation of the 2011 annual fee imposed on branded prescription pharmaceutical manufacturers and importers. Error reports now must be postmarked no later than June 10, 2011. Accordingly, the IRS now expects to issue the final fee calculation on or about August 24, 2011. The final payment date, currently expected to be set at September 30, 2011, remains unchanged.
