CIFT-620ES: Declaration of Estimated Tax for Corporations (2024)

Louisiana · Louisiana LDR · Used for tax years 2024

Louisiana Form CIFT-620ES is the Declaration of Estimated Tax for Corporations. It includes worksheets to calculate or revise estimated corporation income tax and vouchers to submit installment payments.

Who files this form

Any corporation that reasonably expects its Louisiana income tax for the taxable year to be $1,000 or more must make estimated tax payments. Estimated tax is the expected Louisiana income tax for the current period, minus estimated allowable credits.

Subchapter S corporations and other pass-through entities that receive acceptance of the Pass-through Entity Election under LA R.S. 287.732.2 must also make estimated tax payments. These entities should use the tax rate provided under that law.

Estimated payments apply only to income tax. Do not file CIFT-620ES if you pay electronically.

Common mistakes

  • Sending a voucher after paying electronically. The form says not to file CIFT-620ES if payment is made electronically.
  • Mailing cash. Do not send cash. Attach a check or money order to the mailed voucher.
  • Leaving incorrect account information unchanged. Verify the account number, name, and address, and make corrections at latap.revenue.louisiana.gov.
  • Not reporting a changed year end. If it differs from the prior year, check the voucher’s box and enter the appropriate fiscal year ending.
  • Using income totals that do not match. The total income on worksheet Line 2d should equal the estimated taxable income on Line 1.
  • Underpaying or missing estimated payments. The form states that an amount calculated at 12 percent per year on any underpayment or nonpayment will be added to the tax due.

Questions people ask

Can I use an overpayment from last year toward an installment?

Yes. If you elected on last year’s return to apply the overpayment to estimated corporation income tax, you may apply part or all of it to any installment.

What if my estimated tax changes after I make a payment?

Complete the Worksheet for Amending Estimated Income Tax. Subtract allowable credits and previous estimated payments from the amended estimated tax, then divide the unpaid balance by the number of remaining installments.

Must I always make four equal installments?

No. The number and size of installments depend on when your estimated tax first reaches $1,000 or more. The form lists four payments of 25% if the requirement is met before the fourth month, three payments of 33⅓% if first met during months four or five, two payments of 50% if first met during months six through eight, and one payment of 100% if first met during months nine through eleven.

Do estimated payments cover taxes other than income tax?

No. The form states that estimated tax payments apply only to income tax.
