IRS Form 8725 is used to report and pay the 50% excise tax imposed under section 5881 on greenmail; filers must submit it by the 90th day following receipt of any portion of the greenmail.
Plain English

Tax paid via Form 7004
This form is used if tax was already paid when filing the extension, as Form 8725 does not automatically reflect that payment.
✓ Check Line 7 on Form 8725.
Amending a previously filed return
If changes are needed after initial submission, file a corrected copy and write 'Amended' at the top of the form.
✓ Ensure you attach pages if necessary.
Reporting other subject income
Any gain or other income subject to the excise tax that is not part of the main greenmail calculation must be reported here.
✓ Do not forget to include this amount in the total on Line 5.
The trigger event for filing Form 8725 is the receipt of any portion of the greenmail. The deadline is the 90th day following that receipt date. An extension can be requested using Form 7004, but this form does not extend the time for tax payment.
