The benefit and validity period of balance is defined by your employer. Often the benefit can be used until the end of the calendar year, but the practice varies. After the expiration date, the benefit is due and the balance is no longer available. The expiration date cannot be changed. 

Please use your ePassi balance during it's validity period. 

How to check the validity period of your benefit? Sign in to the ePassi Web service, click the benefit icon and you'll see the benefit expiration date when you scroll down.

Please note that you are only eligible for the benefit as long as you have a valid contract with your employer. Once your contract ends, your right to use ePassi ends. You will not be eligible for the benefit after this, and the benefit will not be given to you as cash.

You do have the right to ask for OmaRaha return and you can do as instructed here.
