(b) A corporation is deriving receipts from activity in the metropolitan commuter transportation district if it has receipts within the metropolitan commuter transportation district of one million dollars or more in a taxable year. For purposes of this section, the term "receipts" means the receipts that are subject to the apportionment rules set forth in section two hundred ten-A of this article, and the term "receipts within the metropolitan commuter transportation district" means the receipts included in the numerator of the apportionment factor determined under subdivision two of this section. For purposes of this paragraph, receipts from processing credit card transactions for merchants include merchant discount fees received by the corporation.

(c) A corporation is doing business in the metropolitan commuter transportation district if (i) it has issued credit cards to one thousand or more customers who have a mailing address within the metropolitan commuter transportation district as of the last day of its taxable year, (ii) it has merchant customer contracts with merchants and the total number of locations covered by those contracts equals one thousand or more locations in the metropolitan commuter transportation district to whom the corporation remitted payments for credit card transactions during the taxable year, or (iii) the sum of the number of customers described in subparagraph (i) of this paragraph plus the number of locations covered by its contracts described in subparagraph (ii) of this paragraph equals one thousand or more. As used in this paragraph, the term "credit card" includes bank, credit, travel and entertainment cards.

(d)(i) A corporation with less than one million dollars but at least ten thousand dollars of receipts within the metropolitan commuter transportation district in a taxable year that is part of a unitary group that meets the ownership test under section two hundred ten-C of this article is deriving receipts from activity in the metropolitan commuter transportation district if the receipts within the metropolitan commuter transportation district of the members of the unitary group that have at least ten thousand dollars of receipts within the metropolitan commuter transportation district in the aggregate meet the threshold set forth in paragraph (b) of this subdivision.

(ii) A corporation that does not meet any of the thresholds set forth in paragraph (c) of this subdivision but has at least ten customers, or locations, or customers and locations, as described in paragraph (c), and is part of a unitary group that meets the ownership test under section two hundred ten-C of this article is doing business in the metropolitan commuter transportation district if the number of customers, locations, or customers and locations, within the metropolitan commuter transportation district of the members of the unitary group that have at least ten customers, locations, or customers and locations, within the metropolitan commuter transportation district in the aggregate meets any of the thresholds set forth in paragraph (c) of this subdivision.

(iii) For purposes of this paragraph, any corporation described in paragraph (c) of subdivision two of section two hundred ten-C of this article shall not be considered.

(e) At the end of each year, the commissioner shall review the cumulative percentage change in the consumer price index. The commissioner shall adjust the receipt thresholds set forth in this subdivision if the consumer price index has changed by ten percent or more since the January first, two thousand fifteen or since the date that the thresholds were last adjusted under this subdivision. The thresholds shall be adjusted to reflect that cumulative percentage change in the consumer price index. The adjusted thresholds shall be rounded to the nearest one thousand dollars. As used in this paragraph, "consumer price index" means the consumer price index for all urban consumers (CPI-U) available from the bureau of labor statistics of the United States department of labor. Any adjustment shall apply to tax periods that begin after the adjustment is made.

(f) The commissioner shall determine the rate of tax for taxable years beginning on or after January first, two thousand sixteen by adjusting the rate for taxable years beginning on or after January first, two thousand fifteen and before January first, two thousand sixteen as necessary to ensure that the receipts attributable to such surcharge, as impacted by the chapter of the laws of two thousand fourteen which added this paragraph, will meet and not exceed the financial projections for state fiscal year two thousand sixteen-two thousand seventeen, as reflected in state fiscal year two thousand fifteen-two thousand sixteen enacted budget. The commissioner shall annually determine the rate thereafter using the financial projections for the state fiscal year that commences in the year for which the rate is to be set as reflected in the enacted budget for the fiscal year commencing on the previous April first. 2. The portion of the taxpayer's business activity carried on within the metropolitan commuter transportation district shall be determined by multiplying the tax imposed under section two hundred nine of this article before the deduction of any credits otherwise allowable under this article by a percentage to be determined as follows:

(a) ascertaining the percentage which the average value of the taxpayer's real and tangible personal property, whether owned or rented to it, within the metropolitan commuter transportation district during the period covered by its report bears to the average value of all the taxpayer's real and tangible personal property, whether owned or rented to it, within the state during such period; provided that the term "value of the taxpayer's real and tangible personal property" shall mean the adjusted bases of such properties for federal income tax purposes (except that in the case of rented property such value shall mean the product of (i) eight and (ii) the gross rents payable for the rental of such property during the taxable year); provided, however, that the taxpayer may make a one-time, revocable election to use fair market value as the value of all of its real and tangible personal property, provided that such election is made on or before the due date for filing a report under section two hundred eleven for the taxpayer's first taxable year commencing on or after January first, two thousand fifteen and provided that such election shall not apply to any taxable year with respect to which the taxpayer is included on a combined report unless each of the taxpayers included on such report has made such an election which remains in effect for such year;

(b) ascertaining the percentage of the taxpayer's receipts within the metropolitan commuter transportation district pursuant to the method prescribed in section two hundred ten-A of this article, except that

(i) the numerator of the apportionment fraction under such section two hundred ten-A shall be the denominator of the apportionment fraction under this paragraph,

(ii) the numerator of the apportionment fraction under this paragraph shall be determined by applying the rules in such section two hundred ten-A relating to the numerator of the apportionment fraction as if those rules referenced the metropolitan commuter transportation district rather than this state,

(iii) to the extent that a provision in such section two hundred ten-A provides that eight percent of the receipts specified in that provision should be included in the numerator of the apportionment fraction, ninety percent of such eight percent amount shall be considered within the metropolitan commuter transportation district and one hundred percent of such eight percent amount shall be considered to be within the state, and

(iv) to the extent that a provision in such section two hundred ten-A of this article provides that the receipts specified in that provision shall not be included in the numerator of the apportionment fraction under such section two hundred ten-A, such receipts shall not be included in determining the portion of the taxpayer's business activity carried on within the metropolitan commuter transportation district;

(c) ascertaining the percentage of the total wages, salaries and other personal service compensation, similarly computed, during such period, of employees within the metropolitan commuter transportation district, except general executive officers, to the total wages, salaries and other personal service compensation, similarly computed, during such period, of all the taxpayer's employees within the state, except general executive officers; and

(d) adding together the percentages so determined and dividing the result by the number of percentages. 3. A corporation shall not be deemed to be doing business, employing capital, owning or leasing property, or maintaining an office, or deriving receipts from activity in the metropolitan commuter transportation district, for the purposes of this section, by reason of (a) the maintenance of cash balances with banks or trust companies in the metropolitan commuter transportation district, or (b) the ownership of shares of stock or securities kept in the metropolitan commuter transportation district, if kept in a safe deposit box, safe, vault or other receptacle rented for the purpose, or if pledged as collateral security, or if deposited with one or more banks or trust companies, or brokers who are members of a recognized security exchange, in safekeeping or custody accounts, or (c) the taking of any action by any such bank or trust company or broker, which is incidental to the rendering of safekeeping or custodian service to such corporation, or (d) the maintenance of an office in the metropolitan commuter transportation district by one or more officers or directors of the corporation who are not employees of the corporation if the corporation otherwise is not doing business in the metropolitan commuter transportation district, and does not employ capital or own or lease property in the metropolitan commuter transportation district, or (e) the keeping of books or records of a corporation in the metropolitan commuter transportation district if such books or records are not kept by employees of such corporation and such corporation does not otherwise do business, employ capital, own or lease property or maintain an office in the metropolitan commuter transportation district, or (f) any combination of the foregoing activities. 4. Notwithstanding any contrary provisions of state or local law, the tax surcharge imposed under this section shall not be allowed as a deduction in the computation of any tax imposed under this chapter. Furthermore, the credits otherwise allowable under this article shall not be allowed against the tax surcharge imposed by this section. 5. The provisions concerning reports under sections two hundred ten-C and two hundred eleven shall be applicable to this section, except that for purposes of an automatic extension for six months for filing a report covering the tax surcharge imposed by this section, such automatic extension shall be allowed only if a taxpayer files with the commissioner an application for extension in such form as said commissioner may prescribe by regulation and pays on or before the date of such filing in addition to any other amounts required under this article, either ninety percent of the entire tax surcharge required to be paid under this section for the applicable period, or not less than the tax surcharge shown on the taxpayer's return for the preceding taxable year, if such preceding taxable year was a taxable year of twelve months; provided, however, that in no event shall such amount be less than the product of the following three amounts: (1) the tax surcharge rate in effect for the taxable year pursuant to subdivision one of this section, (2) the fixed dollar minimum applicable to such taxpayer as determined under paragraph (d) of subdivision one of section two hundred ten of this chapter for the taxable year, and (3) the percentage determined under subdivision two of this section for the preceding taxable year, unless the taxpayer was not subject to the tax surcharge imposed pursuant to this section with respect to such year, in which case such percentage shall be deemed to be one hundred percent. The tax surcharge imposed by this section shall be payable to the commissioner in full at the time the report is required to be filed, and such tax surcharge or the balance thereof, imposed on any taxpayer which ceases to exercise its franchise or be subject to the tax surcharge imposed by this section shall be payable to the commissioner at the time the report is required to be filed, provided such tax surcharge of a domestic corporation which continues to possess its franchise shall be subject to adjustment as the circumstances may require; all other tax surcharges of any such taxpayer, which pursuant to the foregoing provisions of this section would otherwise be payable subsequent to the time such report is required to be filed, shall nevertheless be payable at such time. All of the provisions of this article presently applicable are applicable to the tax surcharge imposed by this section. 6. The term metropolitan commuter transportation district as used in this section shall be defined pursuant to section twelve hundred sixty-two of the public authorities law.
