When is Form WH-1606 due?

The due date for filing Form WH-1606 is January 31 of the year following the calendar year being reported.

• For example, for wages and taxes withheld in 2024, the WH-1606 form must be filed by January 31, 2025.

Employers must submit both the form and any balance of tax due by this deadline to avoid penalties and interest. If the due date falls on a weekend or state-recognized holiday, the deadline is generally extended to the next business day.
