5 - My bank account has a block or filter on it. What should I do?
If your bank account has a block or filter on it, you will need to provide your bank with the State of Maryland's Originator Identification Number. An originator identification number identifies the State of Maryland to your bank, so your bank knows that it can allow the electronic payment to proceed. If you need this number, contact taxpayer service for instructions at 410-260-7980, Monday - Friday, 8:00 a.m. - 5:00 p.m. EST.
