2026 dates

These four dates fall on weekdays, so the IRS weekend-and-holiday rule does not move them. January 15, 2027, the fourth payment for tax year 2026, is a Friday.

Uncertain. January 18, 2028 is this site's calculation, not an IRS-published voucher date. January 15, 2028 is a Saturday. January 17, 2028 is the third Monday in January, the Birthday of Martin Luther King, Jr., a legal public holiday under 5 U.S.C. 6103. The IRS weekend-and-holiday rule, described in the estimated-tax FAQ, moves a weekend or holiday due date to the next business day.

Draft Publication 509 for 2027 was not read. Re-check IRS.gov when Form 1040-ES for 2027 is published.
