The EFTPS accepts two types of payment: ACH debit, where you authorize a transaction yourself ACH credit, where you have your financial institution initiate the transaction For an ACH debit, you ask EFTPS to originate a debit entry with your bank, crediting the U.S. Treasury. You submit tax information to EFTPS at least one day before you want the payment to post, and EFTPS validates that information. Once the payment is processed, you receive confirmation and the IRS receives notice that a payment was made. For an ACH credit, you notify your bank that you would like to make a debit from your account and credit the U.S. Treasury. This is all done electronically using a secure payment system.
