Form NYC-400 - 2021 - Instructions                                                                                                                     Page 2 
 
WHO      MUST FILE 
Every corporation subject to the New York City General Corporation Tax or Business Corporation Tax (Title 11, Chapter 6, Subchapter 2 
or Subchapter 3-A of the Administrative Code) must file a declaration (NYC-400) if its estimated tax for the current year can reasonably 
be expected to exceed $1,000.  The term “estimated tax” means the amount of tax the taxpayer estimates to be imposed by section 11-603 
(GCT) or section 11-653 (Business Corporation Tax) of the Administrative Code less the sum of the credits estimated to be allowable 
against the tax.  For a group filing a combined return,  this form should be filed by the group member filing the return and paying the tax.  
In the case of a combined group subject to the Business Corporation Tax, the reporting corporation is the designated agent of the group, as 
defined in Administrative Code §11-654.3(7). 
 
NOTE:           If the current year’s tax is reasonably estimated to exceed $1,000, an estimated payment is required even if this is the first year of busi-
                ness in New York City for the taxpayer or the taxpayer paid only the minimum tax for the preceding year. Failure to pay or underpay-
                ment of estimated tax in these circumstances will result in penalties. 
 
LINE     1  -  DECLARATION OF ESTIMATED TAX FOR CURRENT YEAR 
S corporations and qualified Subchapter S subsidiaries subject to the New York City General Corporation Tax whose tax liability for the 
preceding year exceeds $1,000 are required to pay, with the tax report for the preceding year or with the application for extension of time 
for the filing of such report, 25% of the tax liability for the preceding year as a first installment of estimated tax for the current year.  Every 
C corporation subject to the New York City Business Corporation Tax must file Form NYC-300 (Mandatory First Installment (MFI) by Busi-
ness C Corporations) and pay 25% of the tax liability for the second preceding year as  a first installment of estimated tax for the current 
year if its tax for the second preceding year exceeded $1,000.  The second preceding year’s tax means the tax imposed on the taxpayer by 
section 11-653 of the Administrative Code for the second preceding calendar or fiscal year.  After taking credit for that 25% payment and 
for the amount of any overpayment shown on last year’s return which the taxpayer elected to have applied as a credit against the current 
year’s tax, taxpayers filing estimated tax are required to pay the balance of estimated tax in fractional installments.
