SUMMARY:Partnership and S corporation returns
DESCRIPTION:A month before the individual deadline\, because the K-1s these
  produce are what the partners need to file their own returns. The late-fi
 ling penalty is charged per partner or shareholder per month\, whether or 
 not the entity owes a cent of tax\, so a four-partner firm accrues it four
  times over.
