Declaration of Estimated Tax for Corporation Income Tax
Corporations required to file estimated tax payments:
If your corporation is subject to income tax under Chapter 143, RSMo (including
those with unrelated business taxable income and excluding qualified S
corporations), your corporation is required to make estimated tax payments for
the taxable year if your Missouri estimated tax can reasonably be expected to be
at least $250 (Section 143.521.2, RSMo). Do not use Form MO-1120ES for S
corporation shareholder composite returns.

	 e)	the tax figured by using the current year’s rates but based on the prior
year’s return and the law that applied to the prior year; or
	 f)	 90 percent of the tax for the taxable year computed by placing on
		 an annualized basis the taxable income for the months in the
		 taxable year ending before the month that the installment is
		 required to be paid.
Access dor.mo.gov/intrates.php to obtain the current interest rate.

 hen to file and pay estimated tax payments: You must file the estimated
W
tax payments along with Form MO‑1120ES, on or before the 15th day of the
4th, 6th, 9th, and 12th months of the tax year. When the due date falls on a
Saturday, Sunday, or legal holiday, the payment will be considered timely
if made on the next business day. Payments must accompany the Form
MO‑1120ES. Your corporation will not receive a quarterly billing.

Note: Exceptions (b) and (e) do not apply to large corporations (defined in
Section 143.761.6, RSMo, as one that in any of the three preceding
taxable years had a federal taxable income of at least one million
dollars and Missouri taxable income of at least one hundred thousand
dollars). Please see Section 143.761, RSMo, and 12 CSR 10‑2.067 for other
exceptions provided by law and further clarification.

Paying estimated tax payments online: You can file and pay Declaration
of Estimated Tax for Corporation Income Tax (Form MO-1120ES), online
using a Credit Card or E-Check (Electronic Bank Draft). To file and pay online,
please visit dor.mo.gov/business/payonline.php.

Rounding on estimated tax payments: You must round all cents to the
nearest whole dollar. For 1 cent through 49 cents, round down to the previous
whole dollar amount (round $32.49 down to $32.00) on the form. For 50 cents
through 99 cents, round up to the next whole dollar amount (round $32.50 up to
$33.00) on the form. The zeros have already been placed in the cent columns.

Changes in taxable income: On April 15, your corporation may not be required
to file an estimated tax payment. In the event a change in income later requires
an estimated tax payment, the time for filing is as follows: June 15 if the change
occurs after April 1 and before June 2; September 15 if the change occurs after
June 1 and before September 2; December 15 if the change occurs after
Sep­tem­ber 1. These dates only apply to a calendar year corporation. For fiscal
year corporations, complete the Estimated Tax Worksheet (Section 143.531,
RSMo).
Note: Filing an estimated tax payment, amended estimated tax payment,
or payment on the last installment date of the taxable year will not relieve
the corporation of additions to tax for failure to pay the estimated tax by the
designated due dates.
Additions to tax for failure to pay estimated tax: Section 143.761, RSMo,
provides for additions to tax for underpayment of estimated tax. Calculate the
additions to tax and the applicable rate of interest from the date of the underpaid
installment (Form MO-2220). Interest will be charged on all delinquent payments.
Additions to tax do not apply if each installment is paid timely, and the total amount
of all payments of estimated tax made on or before the last date prescribed for
payment of such installment equals or exceeds:
	 a)	 90 percent of the tax shown on the return (Form MO‑1120) for the
		 taxable year; or
	 b)	the tax shown on the preceding year’s return, if the return showed a tax
liability and was a taxable year of 12 months; or
	c)	90 percent of the tax on the annualized taxable income of periods from
the first of the year to the end of the month preceding that in which an
installment is due; or
	d)	90 percent of the tax computed on the basis of the actual taxable
income for the months in the taxable year ending before the month that
the installment is required to be paid as if such months constituted the
taxable year; or

Amended Estimated Tax Payments
If your corporation has filed an estimated tax payment(s) and later determines its estimated tax has substantially changed, the estimated tax payment
that is to be filed on or before the next filing date, must reflect the amended figures. A worksheet is provided for determining the amended estimated tax.
Note: If the corporation’s estimated tax substantially changes during the year, use the amended computation schedule below to determine the amended
amount to be entered on the remaining Form MO‑1120ES(s). The corporation will not receive a billing. Remit payment when due to avoid additions to
tax for underpayment of estimated tax.
