For the purpose of this section estimated tax means the amount which the bank or financial corporation, estimates as the amount of tax imposed at the rate determined by the department for the preceding year, less the credit allowable. FTB Form 100ES is used to file or pay the estimate payments. If the accounting period is less than 12 months, estimate requirements may vary, depending on the length of the accounting period. BETS Payment Application Rules Payments received on or before the original return due date will be applied to each installment based on the payment received date in relation to the installment due date. The tax is determined by the previous income year.
All tax is required to be paid in full by the original due date of the return.
If the tax return cannot be filed by the original due date, the tax should be paid with an extension voucher. This includes ALL corporate income and franchise tax payments regardless of the type of payment, the amount of the payment, or the income year the payment is for. If the taxpayer tax does not meet the thresholds established for mandatory participation, the taxpayer may request to participate in the program on a voluntary basis. On a voluntary basis the taxpayer is not subject to the EFT penalty. The due dates for EFT payments are the same as for any other method of payment.
