Federal tax deposits must be made by electronic funds transfer.   Beginning January 1, 2011, you must use electronic funds transfer to make all federal tax deposits (such as deposits of employment tax, excise tax, and corporate income tax). Forms 8109 and 8109-B, Federal Tax Deposit Coupon, cannot be used after December 31, 2010. Generally, electronic fund transfers are made using the Electronic Federal Tax Payment System (EFTPS). If you do not want to use EFTPS, you can arrange for your tax professional, financial institution, payroll service, or other trusted third party to make deposits on your behalf. You also may arrange for your financial institution to initiate a same-day wire on your behalf. EFTPS is a free service provided by the Department of Treasury. Services provided by your tax professional, financial institution, payroll service, or other third party may have a fee.

  To get more information about EFTPS or to enroll in EFTPS, visit www.eftps.gov or call 1-800-555-4477. Additional information about EFTPS is also available in Publication 966, The Secure Way to Pay Your Federal Taxes.
