The option to fill up various nomination forms and declarations associated with Payroll is available to employees and also to the Payroll Manager who can do it on their behalf.
There are three forms in total but all might now be visible (form visibility is linked to feature activation), for example - if employee is not participating in ESI then ESI nomination form will not be visible. Sample forms are attached with the article.
Once the nominee details are submitted the nomination form can be downloaded using the Download
button. To change the details use the "Modify" option. Details of gratuity nomination can be viewed from Reports > Payroll > Employee Reports > Gratuity Nomination and Reports > Payroll > Employee Reports > Gratuity Nominee Details.
Some part of PF declaration data is captured as a part of the new joiner information.
The remaining needs to be updated as per the form below.
