Treasury is changing two aspects of payments Starting June 30, 2020.

CONTACT US users will no longer have the option to choose future payment dates. Payments will be processed the day they are scheduled. If you file your OSM-1 Report early, you can still pay your fees on the due date by going back to, selecting the “Pay OSM1” option and scheduling your payment on the due date. All payments will be sent for settlement every 55 minutes of the hour, if you need to cancel your payment contact your account representative immediately.

If you cancel a payment through your financial institution, any assessed fees would be your responsibility.
