New York General City Law Section 25-A-66 - Overpayment.

 66. Overpayment.--(a)   General.--The   administrator,   within  the
  applicable period of limitations, may credit an  overpayment  of  income
  tax and interest on such overpayment against any liability in respect of
  any  tax imposed by this local law or by any local law of the city which
  imposes an unincorporated business income tax on the person who made the
  overpayment, and the balance shall be refunded. Any  refund  under  this
  section shall be made only upon the filing of a return.
(b)  Excessive  withholding.--If  the amount allowable as a credit for
  tax withheld from the taxpayer exceeds  his  tax  to  which  the  credit
  relates, the excess shall be considered an overpayment.
(c) Overpayment by employer.-- If there has been an overpayment of tax
  required  to  be  deducted  and withheld under section fifty-one, refund
  shall be made to the employer only to the extent that the amount of  the
  overpayment was not deducted and withheld by the employer.
(d)  Credits  against  estimated tax.--The administrator may prescribe
  regulations providing for the crediting against the estimated income tax
  for any taxable year of the amount determined to be  an  overpayment  of
  the  income  tax  for  a  preceding  taxable year. If any overpayment of
  income tax is so claimed as a  credit  against  estimated  tax  for  the
  succeeding taxable year, such amount shall be considered as a payment of
  the  income  tax for the succeeding taxable year (whether or not claimed
  as a credit in the declaration of  estimated  tax  for  such  succeeding
  taxable  year),  and  no  claim for credit or refund of such overpayment
  shall be allowed for the taxable year for which the overpayment arises.
(e) Rule where no tax liability.--If there is no tax liability  for  a
  period  in respect of which an amount is paid as income tax, such amount
  shall be considered an overpayment.
(f) Assessment and collection after limitation period.--If any  amount
  of  income  tax  is  assessed  or  collected after the expiration of the
  period of limitations properly applicable thereto, such amount shall  be
  considered an overpayment.
