ACH

The ACH Network is a processing and delivery system that provides for the distribution and settlement of electronic credits and debits among financial institutions. The National Automated Clearing House (NACHA) is responsible for maintaining and policing the electronic payments network commonly referred to as the Automated Clearing House (ACH). For years, the most notable electronic payment program offered was Direct Deposit.

Commonly Used ACH Formats

  • Cash Concentration or Disbursements (CCD)
    The CCD payment format is the only format that does not allow addenda records. Because remittance data is not transmitted with the payment, you will need to use an additional method to transmit remittance information.
  • Cash Concentration or Disbursement Plus Addenda (CCD+)
    The CCD+ format is identical to the CCD format with the addition of one addenda record. Part of the addenda record contains a payment related information field of 80 characters in which data segments can be used.
  • Corporate Trade Payments
    The Corporate Trade Payment (CTX) format was developed to permit the transmission of remittance information. CTX allows for up to 9,999 addenda records. CTX addenda records contain free form information that can accommodate the full EDI 820 Transaction Set or a subset of its segments.

Tax Payments
Electronic tax payment programs usually offer two options, ACH debit or ACH Credit. An ACH Credit is an electronic funds transfer transaction in which the business authorizes its financial institution to send funds to the revenues department's account, allowing the business to initiate ACH credit transfers. You must set up this option with your bank. You are responsible to ensure your payment is received by the tax entity by the due date.

An ACH Debit is an electronic transaction in which the business authorizes the tax department's financial institution to withdraw funds from the business' account and deposit them into the department's account. The business initiates and specifies the amount and date of the withdrawal by calling a toll-free number at the Taxing body.
