hundred forty-eight consecutive days the taxpayer is not present in the

twelve months, which would be treated as a separate taxable period
pursuant to section thirteen hundred twenty-seven of this article, and
which period is contained within the period of five hundred forty-eight
consecutive days, the taxpayer is present in the city for a number of
days which does not exceed an amount which bears the same ratio to
ninety as the number of days contained in that period of less than
twelve months bears to five hundred forty-eight, or
(2) who is not domiciled in such city but maintains a permanent place
of abode in such city and spends in the aggregate more than one hundred
eighty-three days of the taxable year in such city, unless such
individual is in active service in the armed forces of the United
States.
(b) City nonresident individual. A city nonresident individual means
an individual who is not a resident of such city.
(c) City resident estate or trust. A city resident estate or trust
means:
(1) the estate of a decedent who at his death was domiciled in such
city,
(2) a trust, or a portion of a trust, consisting of property
transferred by will of a decedent who at his death was domiciled in such
city, or
(3) a trust, or a portion of a trust, consisting of the property of:
(A) a person domiciled in such city at the time such property was
transferred to the trust, if such trust or portion of a trust was then
irrevocable, or if it was then revocable and has not subsequently become
irrevocable; or
(B) a person domiciled in such city at the time such trust or portion
of a trust became irrevocable, if it was revocable when such property
was transferred to the trust but has subsequently become irrevocable.
For the purposes of the foregoing, a trust or a portion of a trust is

future time, to revest title in the person whose property constitutes
such trust or portion of a trust and a trust or portion of a trust
becomes irrevocable when the possibility that such power may be
exercised has been terminated.

trust means an estate or trust which is not a resident of such city.
