Payment of Tax Due

The REMIC must pay the tax due (page 1, Section II, line 3) in full by the 15th day of the 3rd month following the end of the tax year.

Electronic deposit requirement. REMICs must use electronic funds transfer (EFT) to make all federal tax deposits (such as deposits of employment tax, excise tax, and income tax). Generally, an EFT is made using the Electronic Federal Tax Payment System (EFTPS). If you don’t want to use EFTPS, you can arrange for your tax professional, financial institution, payroll service, or other trusted third party to make electronic deposits on your behalf.

To get more information about EFTPS or to enroll in EFTPS, go to EFTPS.gov or call 800-555-4477. Additional information about EFTPS is also available in Pub. 966.

Same-day wire payment option. If the REMIC fails to submit a deposit transaction on EFTPS by 8:00 p.m. Eastern time the day before the date a deposit is due, it can still make its deposit on time by using the Federal Tax
