Marshall Islands Social Security Administration (09.06.2020) With the recent installation of the Bank of Marshall Islands (BOMI) debit card machine at MISSA’s front desk, a taxpayer will no longer need to write a check nor pay cash for social security contributions. Just like the way customers pay their groceries while shopping at K&K or Payless Supermarket, the MISSA cashier will insert the BOMI debit card to the machine and then enter the amount of MISSA taxes based on the completed MISSA Tax Form MISS-3 that will support the payment.
