When should I pay the mandatory contributions?

You may choose to contribute on a monthly or yearly basis. If you choose to contribute on a yearly basis, you should pay your mandatory contributions to your scheme trustee by the end of each financial year of the scheme. If you choose to contribute on a monthly basis, you should specify to your scheme trustee a monthly date as your contribution day and make your monthly mandatory contributions by that date each month. You should inform your scheme trustee whether you want to contribute on a monthly or yearly basis when you first enroll in an MPF scheme. For the next financial year of the scheme, you should inform your scheme trustee of your choice (monthly or yearly) at least 30 days before the end of each financial year of the scheme.
