ACH Credit is an electronic payment method that you may use to pay tax liabilities. You instruct your financial institution to transfer the funds from your account to ours. We then apply the payment to your tax liability. Payments are made using the Tax Payment (TXP) Banking Convention in the addendum record of a CCD+ formatted record.If you are mandated or interested in paying your tax by this method voluntarily, complete Form EFT-1, Authorization Agreement for certain Electronic Payments. You will be contacted by the department after we receive your form.
