The U.S. partners (individuals) withdrew/cashed out from the foreign partnership as of 2/28/2010 -- which terminated the U.S. persons' involvement -- and the partnership is now owned by a single foreign entity.
When must the U.S. persons file the final Form 8865 -- by 4/15/2011 ? OR 3 1/2 months after 2/28/2010 ?
TIA
