Line 3 - Line 3 is available as an option to satisfy the payment of 
         MFI of estimated tax by using overpayments from prior 
         periods instead of remitting additional money.  The 
         amounts used for this purpose must be overpayments 
         shown on prior period returns already filed.  Do not use 
         overpayments that you anticipate computing on the tax 
         return you will file after you file Form NYC-300. 
 
EXAMPLE 
A calendar-year filer is filing Form NYC-300 by March 15, 2023 
to make the MFI payment for 2023.  The filer reasonably believes 
that when filing its 2022 return due on April 15, 2023, it will have 
an overpayment for 2022.  When filing Form NYC-300, the tax-
payer is not allowed to include on line 3 the 2022 overpayment as 
partial or full payment of the 2023 MFI requirement because the 
2022 return has not yet been filed.
