Employer's Identifying Information
Section 1570
Section 1570.40 Employer's
Identifying Information
a) There shall be one employer's identification number issued for
each political entity under coverage. The designated reporting official shall
file one consolidated report of wages for all departments within the entity for
retroactive coverage under a new coverage agreement for periods prior to
January 1, 1987. Functional units of administration which are integral parts of
the entity, even though maintaining separate divisional payrolls, shall not
report wages separately to the State Agency unless such functional units have
been authorized for reporting purposes by the State Agency.
b) The employer identification number and mailing address shall
not be changed or altered upon the preprinted wage report. If a change of
address or appointment of a new reporting official has occurred, the State
Agency shall be notified immediately in writing. If, through mailing error one
entity receives another entity's report forms, it shall be the responsibility
of the reporting official to immediately contact the State Agency.
