The CT-400-MN form is the official New York State declaration for corporate estimated tax, issued by the Department of Taxation and Finance. Any corporation subject to the Article 9-A franchise tax that expects to owe more than $1,000 in state tax must file quarterly installment payments using this form.
Who Must File
The CT-400-MN is required for domestic corporations and foreign corporations doing business in New York State. Foreign corporations must also report the date they first commenced business activities in New York, as this establishes the start of their filing obligation. Corporations organized under New York law are automatically subject to Article 9-A franchise tax requirements.
Required Information
To complete the CT-400-MN form accurately, corporations need the following data: employer identification number (EIN), filing number assigned by the Tax Department, the tax year ending date, each installment due date, the estimated tax amount owed, and the Metropolitan Transportation Authority (MTA) surcharge amount when applicable. The MTA surcharge applies to corporations conducting business within the Metropolitan Commuter Transportation District.
Installment Schedule and Due Dates
New York State requires four annual estimated tax installment payments. The first installment is due on or before the 15th day of the third month of the tax year. Subsequent installments follow a quarterly schedule. Corporations that miss a payment deadline or underpay their estimated tax may face penalty charges calculated by the Tax Department based on the underpayment amount.
Electronic Filing and Payment
New York State requires most corporations to file and pay electronically. Corporations can submit the CT-400-MN and pay each installment online through the Tax Department's Business Online Services portal. Electronic payment options include direct bank account withdrawal (ACH debit) and credit card. A confirmation number is provided upon successful submission, which corporations should retain for their records.
