SUMMARY:Extended 2025 individual return
DESCRIPTION:The last day for anyone who filed Form 4868 in April. An extens
 ion moved the filing date only — tax owed has been accruing interest and
  a 0.5% monthly late-payment penalty since 15 April.

SUMMARY:Fourth quarter 2026 estimated tax payment

SUMMARY:W-2 and 1099-NEC to recipients and to the government
DESCRIPTION:One date for both copies\, unlike most information returns. The
  penalty for filing one late runs in three steps — corrected within 30 d
 ays\, corrected by 1 August\, and after that — and is charged per form a
 nd per copy\, so a single missed contractor is counted twice. The amounts 
 are indexed each year. Moved from 2027-01-31 because that date is a Sunday
 .

SUMMARY:1099-B\, 1099-S and certain 1099-MISC to recipients
DESCRIPTION:Broker statements and real estate proceeds get two extra weeks 
 over the 1099-NEC\, which is why a brokerage 1099 arrives after everything
  else. Moved from 2027-02-15 because that date is Presidents' Day.

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.
