Any corporation that can reasonably expect its income tax for the taxable year to be $1,000 or more must make estimated tax payments.
The term “estimated tax” means the amount the taxpayer estimates to be the Louisiana income tax imposed for the current period, less 
the amount it estimates to be the sum of any credits allowable against the tax. Estimated tax payments are only applicable to income tax. 
Subchapter S corporations and other pass-through entities who receive an acceptance of the Pass-through Entity Election under LA R.S. 
287.732.2 must make estimated tax payments. These entities should use the tax rate provided under LA R.S. 287.732.2 to compute 
their estimated tax. 
Estimated payments must be made, generally, on or before the fifteenth day of the fourth month, the sixth month, the ninth month, and 
the twelfth month of the taxable year. For taxable periods beginning in 2023, refer to the table below to determine the date the installment 
payments are due. The table below summarizes the due dates and amounts of installment payments where liability for declarations is 
caused by an event occurring within a taxable period.

Do not send cash. A CIFT-620ES for Louisiana estimated corporation             income tax should not be filed if payment is made electronically.  
If a new estimate is made after paying any installment of estimated corporation income tax, the amount of each remaining installment 
should be the amount of the revised estimated corporation income tax, less the total amount of any previous payments made during the 
taxable year, divided by the number of remaining installments due for the taxable year. 
If you had an overpayment of tax on your last year’s return and elected to apply it as a credit to your estimated corporation income tax, 
the amount of overpayment may be applied in part or in full to any installment.
There shall be added to the tax due an amount computed at the rate of 12 percent per annum on the sum of any underpayment or 
nonpayment of estimated tax.
