Return and Payment

Oil Spill Response Fee

You may use our Online Services to file the return, which covers a one-year calendar period and is due on or before the following January 25th. The OSR Fund reached the fund maximum in January 1991 and the OSR fee is not currently being collected.
When the fee is active, a monthly return and fee are due on the 25th day of the calendar month following the reporting period.
