N.Y. Mil. Law § 315
The collection from any person in the military service of any tax on the income of such person, whether falling due prior to or during his period of military service, shall be deferred for a period extending not more than six months after the termination of his period of military service, if such person's ability to pay such tax is materially impaired by reason of such service. No interest on any amount of tax, collection of which is deferred for any period under this section, shall accrue for such period of deferment, by reason of such non-payment. The running of any statute of limitations against collection of such tax, by distraint or otherwise, shall be suspended for the period of military service, of any individual, the collection of whose tax is deferred under this section, and for an additional period of nine months beginning with the day following the termination of his period of military service.
