What the New York Form CT-400 (2021) Is For
You use New York Form CT-400 2021 to submit quarterly estimated tax installments for corporations operating in New York State during the 2021 tax year. This form helps you meet the estimated tax for corporations requirements when projected annual liability exceeds applicable thresholds set by New York tax law for 2021.
The form serves as a payment voucher and declaration for the second, third, and fourth installments supporting each New York State corporation tax payment obligation cycle. You do not use this form for the mandatory first installment, as it requires a separate submission method under New York filing rules.
When You’d Use New York Form CT-400 (2021)
You use New York Form CT-400 2021 when the projected corporate tax exceeds one thousand dollars for the tax year 2021, after submitting the mandatory first installment. The filing applies only after Form CT-300 has been filed, since this form covers second, third, and fourth installment payments required under New York filing rules.
You also file the form when estimates change on an official installment due date, which affects the expected annual liability for the same tax year. Any adjustment must follow the installment timing rules governing New York corporate estimated tax calculations and payment schedules for corporations subject to state franchise tax rules.
Key Rules or Details for 2021

This requirement applies to corporations filing under Articles 9, 9-A, and 33, based on projected annual liability used to determine filing obligations.
You do not use this form for the mandatory first installment, as separate rules govern initial estimated payments for corporations following installment schedule rules. Each CT-400 estimated tax payment applies only to the second, third, and fourth quarterly periods within the same tax year as prescribed by New York authorities.
