ACH/EFT payment information

The Oklahoma Tax Commission accepts EFT Credit and EFT Debit payments of withholding taxes.

All taxpayers can voluntarily participate in the EFT program.

How to apply

The Oklahoma Tax Commission requires all EFT users to apply for approval before submitting tax payment files.

For more information about making EFT Credit payments, visit the Oklahoma Tax Commission website and navigate to the Electronic Funds Transfer Filing Guide from the Forms and Publications page.

Payment and other information

ACH Credit payments must be initiated by the taxpayer's bank at least one business day prior to the due date.

For the purpose of the EFT program, the Oklahoma Tax Commission will adopt the same treatment as the Federal Reserve System for recognizing due dates that fall on weekends or Federal Reserve holidays. Thus, when the statutory due date falls on a weekend or a holiday observed by the Federal Reserve, the Oklahoma Tax Commission will allow payments to be credited on the next business day. However, when the statutory due date is the next day following a weekend or observed holiday, the taxpayer would be responsible for initiating the payment transaction two business days before the due date or at such other time as will allow the payment transaction to be credited to the state's account on the statutory due date.
