3. (3) A taxpayer submits a request to the Franchise Tax Board and is granted permission to make electronic funds transfers.

(f) For purposes of this section:

1. (1) “Electronic funds transfer” means any transfer of funds, other than a transaction originated by check, draft, or similar paper instrument, that is initiated through an electronic terminal, telephonic instrument, or computer or magnetic tape, so as to order, instruct, or authorize a financial institution to debit or credit an account. Electronic funds transfer shall be accomplished by an automated clearinghouse debit, automated clearinghouse credit, a Federal Reserve Wire Transfer (Fedwire), or by an international funds transfer.
2. (2) “Automated clearinghouse” means any federal reserve bank, or an organization established by agreement with the National Automated Clearing House Association, that operates as a clearinghouse for transmitting or receiving entries between banks or bank accounts and that authorizes an electronic transfer of funds between those banks or bank accounts.
3. (3) “Automated clearinghouse debit” means a transaction in which any department of the state, through its designated depository bank, originates an automated clearinghouse transaction debiting the taxpayer’s bank account and crediting the state’s bank account for the amount of tax. Banking costs incurred for the automated clearinghouse debit transaction by the taxpayer shall be paid by the state.
4. (4) “Automated clearinghouse credit” means an automated clearinghouse transaction in which the taxpayer, through its own bank, originates an entry crediting the state’s bank account and debiting its own bank account. Banking costs incurred by the state for the automated clearinghouse credit transaction may be charged to the taxpayer.
5. (5) “Fedwire” means any transaction originated by the taxpayer and utilizing the national electronic payment system to transfer funds through federal reserve banks, pursuant to which the taxpayer debits its own bank account and credits the state’s bank account. Electronic funds transfers may be made by Fedwire only if prior approval is obtained from the Franchise Tax Board and the taxpayer is unable, for reasonable cause, to make payments pursuant to paragraph (3) or (4). Banking costs charged to the taxpayer and to the state may be charged to the taxpayer.
6. (6) “International funds transfer” means any transaction originated by the taxpayer and utilizing the international electronic payment system to transfer funds, pursuant to which the taxpayer debits its own bank account and credits the state’s bank account.
7. (7) In determining whether a payment or total tax liability exceeds the amounts established in subdivision (a), the income of all taxpayers whose income derived from, or attributable to, sources within this state is required to be determined by a combined report shall be aggregated and the total aggregate amount shall be considered to be the income of a single taxpayer for purposes of determining the payment or total tax liability of a single taxpayer.
