Forms W-4: Additional Requirements
Section 2510
Section 2510.20 Forms W-4:
Additional Requirements
In addition to the requirements
of Section 2510.10, for each new employee and for each employee making any
changes on their withholding certificates (Form C-25.1), the agency must
provide a duplicate of the withholding exemption certificate either on hard-copy
or magnetic tape to the Comptroller. For employees claiming exempt from tax
for a given calendar year, and who wish to maintain such exempt status for the
next year, the agency must receive a new withholding exemption certificate from
the employee and provide a duplicate to the Comptroller by April 20 of the next
calendar year. An employee failing to file the required annual exempt status
withholding statement will have his withholding computed as if he were single,
claiming zero exemptions.
