Monthly Pay Date for December Earnings is January 2, 2018
For UW employees who are paid on the 1st of each month, the monthly pay date for December 2017 earnings is Tuesday, January 2, 2018. January 2 is the pay date because January 1 (New Year's Day) is a Federal Reserve holiday.
When a pay date falls on a weekend or Federal Reserve holiday, the pay date is usually the previous business day. An exception to this is the monthly pay date that falls on New Year's Day, January 1.
To avoid tax-related issues, the January 1 pay date for December earnings is paid in the new calendar year and must be the first "official banking business day" following the New Year's holiday. The "official banking business day" is defined as a calendar day other than a Saturday, Sunday or a Federal Reserve holiday.
