Taxpayer Filing Information

Once an Information Provider is approved to file its tax forms online with the BOE, the Information Provider must continue filing its tax forms online until otherwise instructed by the BOE. Information Providers filing Motor Fuels Tax returns online must also make payments using Electronic Funds Transfer (EFT). Failure to file Motor Fuels tax forms online and make payments through the EFT system may result in revocation of an Information Provider's license. If an Information Provider experiences any electronic transmission problems, it should contact the BOE immediately at 1-800-400-7115 for assistance in resolving the problem.

Payment Options

Information Providers filing returns online must also electronically pay any amount owed on a return on or before the due date of the return using Electronic Funds Transfer (EFT). A payment made after the due date may be subject to interest and penalty charges. An EFT payment is a separate electronic transmission from the return online transmission. If the Information Provider is currently set up to make payments using the Special Taxes and Fees' Electronic Funds Transfer (EFT) Program, it will continue to do so. If, however, it is not set up to make payments through the EFT Program, the Information Provider must make arrangements to do so.

For information on making your payments through the electronic funds transfer system, please refer to the EFT Information Guide available on the BOE's website at To receive a copy by mail, please contact the BOE at 1-800-400-7115. Once the Information Provider is set up to submit tax forms and payments electronically with the BOE, it must continue to do so until further notified by the BOE. Failure to pay electronically may result in the assessment of penalty charges and/or license revocation.


Information is transmitted over the Internet. Although precautionary measures are in place, the Board of Equalization (BOE) does not guarantee the security of information as it is being transmitted.

The BOE is not liable for system failures, outages, damages or penalties. In the event a transmission is interrupted for any reason, the BOE does not guarantee a transaction is received timely. Responsibility for filing a tax form and submitting payment for amounts due remains with each Online Participant. A paper return may not be filed when participating in online filing. If an Information Provider experiences any electronic transmission problems, it should contact the BOE immediately at 1-800-400-7115 for assistance in resolving the problem.
