As soon as your employer has enrolled you with JAM!, you'll receive an email with the login data for your personal MyJAM!. If you log in, you can add your personal details to the employment agreement. Think of your address details, but also a copy of your identification card. Hereafter, the details you've entered need to be approved or declined by your employer. Not just your employer, but also you have the right to decline a part of the enrolment. If your employer has entered a wage which is too low, you can reject this and add a note. 

After all the data has been approved by both you and your employer, we verify if everything is correct and complete. Consequently, you'll receive an email which states you can sign your contract online in your MyJAM! account. If desired, you can also sign directly for the wage tax.
