EFT transactions for wage withholding tax do not allow for the payment of penalty and interest as part of the transaction. The penalty and interest should be paid with a check and an explanatory letter sent to the Department. Alternatively, the total of the tax, penalty and interest can be paid electronically and contact the Department by mail or phone and request the penalty and interest amounts be properly allocated.

A tax form is not required to be filed for payments of wage withholding tax, estimated income tax, estimated severance tax, income tax extensions, and PUC fixed utilities fees. These are paperless transactions. All other EFT transactions require a tax return. The tax return should be mailed in the same time frame as payments made by check.

The 3 to 5 digit tax type code identifies the tax being paid by EFT. The tax type codes available for electronic payment are listed on the back (page 2) of the Authorization for Electronic Funds Transfer form (DR 5785). The tax type codes for the taxes you are registered to pay will appear in a drop down menu when you initiate a payment on the Web.

You can change your bank account information by managing your account, including at the time you are making a payment.
