(a) Business income base. For taxable years beginning before January first, two thousand sixteen, the amount prescribed by this paragraph shall be computed at the rate of seven and one-tenth percent of the taxpayer's business income base. For taxable years beginning on or after January first, two thousand sixteen, the amount prescribed by this paragraph shall be six and one-half percent of the taxpayer's business income base. The taxpayer's business income base shall mean the portion of the taxpayer's business income apportioned within the state as hereinafter provided. However, in the case of a small business taxpayer, as defined in paragraph (f) of this subdivision, the amount prescribed by this paragraph shall be computed pursuant to subparagraph (iv) of this paragraph and in the case of a manufacturer, as defined in subparagraph (vi) of this paragraph, the amount prescribed by this paragraph shall be computed pursuant to subparagraph (vi) of this paragraph, and, in the case of a qualified emerging technology company, as defined in subparagraph (vii) of this paragraph, the amount prescribed by this paragraph shall be computed pursuant to subparagraph (vii) of this paragraph.

(iv) for taxable years beginning before January first, two thousand sixteen, if the business income base is not more than two hundred ninety thousand dollars the amount shall be six and one-half percent of the business income base; if the business income base is more than two hundred ninety thousand dollars but not over three hundred ninety thousand dollars the amount shall be the sum of (1) eighteen thousand eight hundred fifty dollars, (2) seven and one-tenth percent of the excess of the business income base over two hundred ninety thousand dollars but not over three hundred ninety thousand dollars and (3) four and thirty-five hundredths percent of the excess of the business income base over three hundred fifty thousand dollars but not over three hundred ninety thousand dollars;

(v) if the taxable period to which subparagraph (iv) of this paragraph applies is less than twelve months, the amount prescribed by this paragraph shall be computed as follows:

(A) Multiply the business income base for such taxpayer by twelve;

(B) Divide the result obtained in (A) by the number of months in the taxable year;

(C) Compute an amount pursuant to subparagraph (iv) as if the result obtained in (B) were the taxpayer's business income base;

(D) Multiply the result obtained in (C) by the number of months in the taxpayer's taxable year;

(E) Divide the result obtained in (D) by twelve.

(vi) for taxable years beginning on or after January first, two thousand fourteen, the amount prescribed by this paragraph for a taxpayer that is a qualified New York manufacturer, shall be computed at the rate of zero percent of the taxpayer's business income base. The term "manufacturer" shall mean a taxpayer that during the taxable year is principally engaged in the production of goods by manufacturing, processing, assembling, refining, mining, extracting, farming, agriculture, horticulture, floriculture, viticulture or commercial fishing. However, the generation and distribution of electricity, the distribution of natural gas, and the production of steam associated with the generation of electricity shall not be qualifying activities for a manufacturer under this subparagraph. Moreover, in the case of a combined report, the combined group shall be considered a "manufacturer" for purposes of this subparagraph only if the combined group during the taxable year is principally engaged in the activities set forth in this paragraph, or any combination thereof. A taxpayer or, in the case of a combined report, a combined group shall be "principally engaged" in activities described above if, during the taxable year, more than fifty percent of the gross receipts of the taxpayer or combined group, respectively, are derived from receipts from the sale of goods produced by such activities. In computing a combined group's gross receipts, intercorporate receipts shall be eliminated. A "qualified New York manufacturer" is a manufacturer that has property in New York that is described in clause (A) of subparagraph (i) of paragraph (b) of subdivision one of section two hundred ten-B of this article and either (I) the adjusted basis of such property for New York state tax purposes at the close of the taxable year is at least one million dollars or (II) all of its real and personal property is located in New York. A taxpayer or, in the case of a combined report, a combined group, that does not satisfy the principally engaged test may be a qualified New York manufacturer if the taxpayer or the combined group employs during the taxable year at least two thousand five hundred employees in manufacturing in New York and the taxpayer or the combined group has property in the state used in manufacturing, the adjusted basis of which for New York state tax purposes at the close of the taxable year is at least one hundred million dollars.

(vii) For a taxpayer that is defined as a qualified emerging technology company under paragraph (c) of subdivision one of section thirty-one hundred two-e of the public authorities law regardless of the ten million dollar limitation expressed in subparagraph one of such paragraph (c) the amount prescribed by this paragraph shall be computed at the rate of 5.7 percent for taxable years beginning on or after January first, two thousand fifteen and before January first, two thousand sixteen, 5.5 percent for taxable years beginning on or after January first two thousand sixteen and before January first, two thousand eighteen, and 4.875 percent for taxable years beginning on or after January first, two thousand eighteen.

(viii) (A) In computing the business income base, taxpayers shall be allowed both a prior net operating loss conversion subtraction under this subparagraph and a net operating loss deduction under subparagraph (ix) of this paragraph. The prior net operating loss conversion subtraction computed under this subparagraph shall be applied against the business income base before the net operating loss deduction computed under subparagraph (ix) of this paragraph.

(B) Prior net operating loss conversion subtraction.

(1) Definitions.

(I) "Base year" means the last taxable year beginning on or after January first, two thousand fourteen and before January first, two thousand fifteen.

(II) "Unabsorbed net operating loss" means the unabsorbed portion of net operating loss as calculated under paragraph (f) of subdivision nine of section two hundred eight of this article or subsection (k-1) of section fourteen hundred fifty-three of this chapter as such sections were in effect on December thirty-first, two thousand fourteen, that was not deductible in previous taxable years and was eligible for carryover on the last day of the base year subject to the limitations for deduction under such sections, including any net operating loss sustained by the taxpayer during the base year.

(III) "Base year BAP" means the taxpayer's business allocation percentage as calculated under paragraph (a) of subdivision three of this section for the base year, or the taxpayer's allocation percentage as calculated under section fourteen hundred fifty-four of this chapter for purposes of calculating entire net income for the base year, as such sections were in effect on December thirty-first, two thousand fourteen.

(IV) "Base year tax rate" means the taxpayer's tax rate for the base year as calculated under this paragraph or subsection (a) of section fourteen hundred fifty-five of this chapter, as such provisions were in effect on December thirty-first, two thousand fourteen.

(2) The prior net operating loss conversion subtraction shall be calculated as follows:

(I) The taxpayer shall first calculate the tax value of its unabsorbed net operating loss for the base year. The value is equal to the product of (I) the amount of the taxpayer's unabsorbed net operating loss, (II) the taxpayer's base year BAP, and (III) the taxpayer's base year tax rate.

(II) The product determined under item (I) of this subclause is then divided by six and one-half percent, or in the case of a qualified New York manufacturer, five and seven-tenths percent. This result shall equal the taxpayer's prior net operating loss conversion subtraction pool.

(III) The taxpayer's prior net operating loss conversion subtraction for the taxable year shall equal one-tenth of its net operating loss conversion subtraction pool plus any amount of unused prior net operating loss conversion subtraction from preceding taxable years. Provided, however, the prior net operating loss conversion subtraction of a small business corporation, as defined in paragraph (f) of this subdivision, as of the last day of the base year, shall not be subject to the one-tenth limitation in the previous sentence.

(IV) In lieu of the subtraction described in item (III) of this subclause, if the taxpayer so elects, the taxpayer's prior net operating loss conversion subtraction for the tax years beginning on or after January first, two thousand fifteen and before January first, two thousand seventeen shall equal in each year, not more than one-half of its net operating loss conversion subtraction pool until the pool is exhausted. If the pool is not exhausted at the end of such time period, the remainder of the pool shall be forfeited. The taxpayer shall make such revocable election on its first return for the tax year beginning on or after January first, two thousand fifteen and before January first, two thousand sixteen by the due date for such return (determined with regard to extensions).

(3) Combined groups. (I) Where a taxpayer was properly included or required to be included in a combined report for the base year pursuant to section two hundred eleven of this article or a combined return under section fourteen hundred sixty-two of this chapter, as such sections were in effect on December thirty-first, two thousand fourteen, and the members of the combined group for the base year are the same as the members of the combined group for the taxable year immediately succeeding the base year, the combined group shall calculate its prior net operating loss conversion subtraction pool using the combined group's total unabsorbed net operating loss, base year BAP, and base year tax rate.

(II) If a combined group includes additional members in the taxable year immediately succeeding the base year that were not included in the combined group during the base year, each base year combined group and each taxpayer that filed separately in the base year but is included in the combined group in the taxable year succeeding the base year shall calculate its prior net operating loss conversion subtraction pool, and the sum of the pools shall be the combined prior net operating loss conversion subtraction pool of the combined group.

(III) If a taxpayer was properly included in a combined report for the base year and files a separate report in a subsequent taxable year, then the amount of remaining prior net operating loss conversion subtraction allowed to the taxpayer filing such separate report shall be proportionate to the amount that such taxpayer contributed to the prior net operating loss conversion subtraction pool on a combined basis, and the remaining prior net operating loss conversion subtraction allowed to the remaining members of the combined group shall be reduced accordingly.

(IV) If a taxpayer filed a separate report for the base year and is properly included in a combined report in a subsequent taxable year, then the prior net operating loss conversion subtraction pool of the combined group shall be increased by the amount of the remaining net operating loss conversion subtraction allowed to the taxpayer at the time the taxpayer is properly included in the combined group.

(4) The prior net operating loss conversion subtraction may be used to reduce the taxpayer's tax on the apportioned business income base to the higher of the tax on the capital base under paragraph (b) of this subdivision or the fixed dollar minimum under paragraph (d) of this subdivision. Unless the taxpayer has made the election provided for in item (IV) of subclause two of this clause, any amount of unused subtraction shall be carried forward to subsequent tax year or years until the prior net operating loss conversion subtraction pool is exhausted, but for no longer than twenty taxable years, or the taxable year beginning on or after January first, two thousand thirty-five but before January first, two thousand thirty-six, whichever comes first. Such amount carried forward shall not be subject to the one-tenth limitation for the subsequent tax year or years. However, if the taxpayer elects to compute its prior net operating loss conversion subtraction pursuant to item (IV) of subclause two of this clause, the taxpayer shall not carry forward any unused amount of such subtraction to any tax year beginning on or after January first, two thousand seventeen.

(ix) Net operating loss deduction. In computing the business income base, a net operating loss deduction shall be allowed. A net operating loss deduction is the amount of net operating loss or losses from one or more taxable years that are carried forward or carried back to a particular taxable year. A net operating loss is the amount of a business loss incurred in a particular tax year multiplied by the apportionment factor for that year as determined under section two hundred ten-A of this article. The maximum net operating loss deduction that is allowed in a taxable year is the amount that reduces the taxpayer's tax on the apportioned business income base to the higher of the tax on the capital base or the fixed dollar minimum. Such deduction and loss are determined in accordance with the following:

(1) Such net operating loss deduction is not limited to the amount allowed under section one hundred seventy-two of the internal revenue code or the amount that would have been allowed if the taxpayer had not made an election under subchapter S of chapter one of the internal revenue code.

(2) Such net operating loss deduction shall not include any net operating loss incurred during any taxable year beginning prior to January first, two thousand fifteen, or during any taxable year in which the taxpayer was not subject to the tax imposed by this article.

(3) A taxpayer that files as part of a federal consolidated return but on a separate basis for purposes of this article must compute its deduction and loss as if it were filing on a separate basis for federal income tax purposes.

(4) A net operating loss may be carried back three taxable years preceding the taxable year of the loss ("the loss year"). However no loss can be carried back to a taxable year beginning before January first, two thousand fifteen. The loss is first carried to the earliest of the three taxable years. If it is not entirely used in that year, it is carried to the second taxable year preceding the loss year, and any remaining amount is carried to the taxable year immediately preceding the loss year. Any unused amount of loss then remaining may be carried forward for as many as twenty taxable years following the loss year. Losses carried forward are carried forward first to the taxable year immediately following the loss year, then to the second taxable year following the loss year, and then to the next immediately subsequent taxable year or years until the loss is used up or the twentieth taxable year following the loss year, whichever comes first.

(5) Such net operating loss deduction shall not include any net operating loss incurred during a New York S year; provided, however, a New York S year must be treated as a taxable year for purposes of determining the number of taxable years to which a net operating loss may be carried forward.

(6) Where there are two or more apportioned net operating losses, or portions thereof, carried back or carried forward to be deducted in one particular tax year from apportioned business income, the earliest apportioned loss incurred must be applied first.

(7) A taxpayer may elect to waive the entire carryback period with respect to a net operating loss. Such election must be made on the taxpayer's original timely filed return (determined with regard to extensions) for the taxable year of the net operating loss for which the election is to be in effect. Once an election is made for a taxable year, it shall be irrevocable for that taxable year. A separate election must be made for each loss year. This election applies to all members of a combined group.

(b) Capital base. (1) (i) The amount prescribed by this paragraph shall be computed at .15 percent for each dollar of the taxpayer's total business capital, or the portion thereof apportioned within the state as hereinafter provided for taxable years beginning before January first, two thousand sixteen. However, in the case of a cooperative housing corporation as defined in the internal revenue code, the applicable rate shall be .04 percent until taxable years beginning on or after January first, two thousand twenty. The rate of tax for subsequent tax years shall be as follows: .125 percent for taxable years beginning on or after January first, two thousand sixteen and before January first, two thousand seventeen; .100 percent for taxable years beginning on or after January first, two thousand seventeen and before January first, two thousand eighteen; .075 percent for taxable years beginning on or after January first, two thousand eighteen and before January first, two thousand nineteen; .050 percent for taxable years beginning on or after January first, two thousand nineteen and before January first, two thousand twenty; .025 percent for taxable years beginning on or after January first, two thousand twenty and before January first, two thousand twenty-one; and zero percent for years beginning on or after January first, two thousand twenty-one. The rate of tax for a qualified New York manufacturer shall be .132 percent for taxable years beginning on or after January first, two thousand fifteen and before January first, two thousand sixteen, .106 percent for taxable years beginning on or after January first, two thousand sixteen and before January first, two thousand seventeen, .085 percent for taxable years beginning on or after January first, two thousand seventeen and before January first, two thousand eighteen; .056 percent for taxable years beginning on or after January first, two thousand eighteen and before January first, two thousand nineteen; .038 percent for taxable years beginning on or after January first, two thousand nineteen and before January first, thousand twenty; .019 percent for taxable years beginning on or after January first, two thousand twenty and before January first, two thousand twenty-one; and zero percent for years beginning on or after January first, two thousand twenty-one. (ii) In no event shall the amount prescribed by this paragraph exceed three hundred fifty thousand dollars for qualified New York manufacturers and for all other taxpayers five million dollars.

(2) For purposes of subparagraph one of this paragraph, the term "manufacturer" shall mean a taxpayer that during the taxable year is principally engaged in the production of goods by manufacturing, processing, assembling, refining, mining, extracting, farming, agriculture, horticulture, floriculture, viticulture or commercial fishing. Moreover, for purposes of computing the capital base in a combined report, the combined group shall be considered a "manufacturer" for purposes of this subparagraph only if the combined group during the taxable year is principally engaged in the activities set forth in this subparagraph, or any combination thereof. A taxpayer or, in the case of a combined report, a combined group shall be "principally engaged" in activities described above if, during the taxable year, more than fifty percent of the gross receipts of the taxpayer or combined group, respectively, are derived from receipts from the sale of goods produced by such activities. In computing a combined group's gross receipts, intercorporate receipts shall be eliminated. A "qualified New York manufacturer" is a manufacturer that has property in New York that is described in clause (A) of subparagraph (i) of paragraph (b) of subdivision one of section two hundred ten-B of this article and either (i) the adjusted basis of that property for New York state tax purposes at the close of the taxable year is at least one million dollars or (ii) all of its real and personal property is located in New York. In addition, a "qualified New York manufacturer" means a taxpayer that is defined as a qualified emerging technology company under paragraph (c) of subdivision one of section thirty-one hundred two-e of the public authorities law regardless of the ten million dollar limitation expressed in subparagraph one of such paragraph. A taxpayer or, in the case of a combined report, a combined group, that does not satisfy the principally engaged test may be a qualified New York manufacturer if the taxpayer or the combined group employs during the taxable year at least two thousand five hundred employees in manufacturing in New York and the taxpayer or the combined group has property in the state used in manufacturing, the adjusted basis of which for New York state tax purposes at the close of the taxable year is at least one hundred million dollars.

(d) Fixed dollar minimum. (1) (A) The amount prescribed by this paragraph for New York S corporations, other than New York S corporations that are qualified New York manufacturers or qualified emerging technology companies, will be determined in accordance with the following table: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 25 more than $100,000 but not over $250,000 $ 50 more than $250,000 but not over $500,000 $ 175 more than $500,000 but not over $1,000,000 $ 300 more than $1,000,000 but not over $5,000,000 $1,000 more than $5,000,000 but not over $25,000,000 $3,000 Over $25,000,000 $4,500

(B) Provided further, the amount prescribed by this paragraph for New York S corporations that are qualified New York manufacturers, as defined in subparagraph (vi) of paragraph (a) of this subdivision, and for New York S corporations that are qualified emerging technology companies under paragraph (c) of subdivision one of section thirty-one hundred two-e of the public authorities law regardless of the ten million dollar limitation expressed in subparagraph one of such paragraph (c), will be determined in accordance with the following tables. For taxable years beginning on or after January 1, 2015 and before January 1, 2016: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 22 more than $100,000 but not over $250,000 $ 44 more than $250,000 but not over $500,000 $ 153 more than $500,000 but not over $1,000,000 $ 263 more than $1,000,000 but not over $5,000,000 $ 877 more than $5,000,000 but not over $25,000,000 $2,631 Over $25,000,000 $3,947 For taxable years beginning on or after January 1, 2016 and before January 1, 2018: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 21 more than $100,000 but not over $250,000 $ 42 more than $250,000 but not over $500,000 $ 148 more than $500,000 but not over $1,000,000 $ 254 more than $1,000,000 but not over $5,000,000 $ 846 more than $5,000,000 but not over $25,000,000 $2,538 Over $25,000,000 $3,807 For taxable years beginning on or after January 1, 2018: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 19 more than $100,000 but not over $250,000 $ 38 more than $250,000 but not over $500,000 $ 131 more than $500,000 but not over $1,000,000 $ 225 more than $1,000,000 but not over $5,000,000 $ 750 more than $5,000,000 but not over $25,000,000 $2,250 Over $25,000,000 $3,375

(C) Provided further, the amount prescribed by this paragraph for a qualified New York manufacturer, as defined in subparagraph (vi) of paragraph (a) of this subdivision, and a qualified emerging technology company under paragraph (c) of subdivision one of section thirty-one hundred two-e of the public authorities law regardless of the ten million dollar limitation expressed in subparagraph one of such paragraph (c), that is not a New York S corporation, will be determined in accordance with the following tables. However, with respect to qualified New York manufacturers, the amounts in these tables will apply in the case of a combined report only if the combined group satisfies the requirements to be a qualified New York manufacturer as set forth in such subparagraph (vi). For tax years beginning on or after January 1, 2015 and before January 1, 2016: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 22 more than $100,000 but not over $250,000 $ 66 more than $250,000 but not over $500,000 $ 153 more than $500,000 but not over $1,000,000 $ 439 more than $1,000,000 but not over $5,000,000 $1,316 more than $5,000,000 but not over $25,000,000 $3,070 Over $25,000,000 $4,385 For tax years beginning on or after January 1, 2016 and before January 1, 2018: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 21 more than $100,000 but not over $250,000 $ 63 more than $250,000 but not over $500,000 $ 148 more than $500,000 but not over $1,000,000 $ 423 more than $1,000,000 but not over $5,000,000 $1,269 more than $5,000,000 but not over $25,000,000 $2,961 Over $25,000,000 $4,230 For tax years beginning on or after January 1, 2018: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 19 more than $100,000 but not over $250,000 $ 56 more than $250,000 but not over $500,000 $ 131 more than $500,000 but not over $1,000,000 $ 375 more than $1,000,000 but not over $5,000,000 $1,125 more than $5,000,000 but not over $25,000,000 $2,625 Over $25,000,000 $3,750

(D) Otherwise, for all other taxpayers not covered by clauses (A), (B), (C) and (D-1) of this subparagraph, the amount prescribed by this paragraph will be determined in accordance with the following table: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 25 more than $100,000 but not over $250,000 $ 75 more than $250,000 but not over $500,000 $ 175 more than $500,000 but not over $1,000,000 $ 500 more than $1,000,000 but not over $5,000,000 $1,500 more than $5,000,000 but not over $25,000,000 $3,500 more than $25,000,000 but not over $50,000,000 $5,000 more than $50,000,000 but not over $100,000,000 $10,000 more than $100,000,000 but not over $250,000,000 $20,000 more than $250,000,000 but not over $500,000,000 $50,000 more than $500,000,000 but not over $1,000,000,000 $100,000 Over $1,000,000,000 $200,000

(D-1) In the case of a REIT or a RIC that is not a captive REIT or captive RIC, the amount prescribed by this paragraph will be determined in accordance with the following table: If New York receipts are: The fixed dollar minimum tax is: not more than $100,000 $ 25 more than $100,000 but not over $250,000 $ 75 more than $250,000 but not over $500,000 $ 175 more than $500,000 $ 500

(E) For purposes of this paragraph, New York receipts are the receipts included in the numerator of the apportionment factor determined under section two hundred ten-A for the taxable year.

(2) If the taxable year is less than twelve months, the amount of New York receipts is determined by dividing the amount of the receipts for the taxable year by the number of months in the taxable year and multiplying the result by twelve, and the amount prescribed by this paragraph shall be reduced by twenty-five percent of the period for which the taxpayer is subject to tax is more than six months but not more than nine months and by fifty percent if the period for which the taxpayer is subject to tax is not more than six months. In the case of a termination year of a New York S corporation, the sum of the tax computed under this paragraph for the S short year and for the C short year shall not be less than the amount computed under this paragraph as if the corporation were a New York C corporation for the entire taxable year.

(f) For purposes of this section, the term "small business taxpayer" shall mean a taxpayer (i) which has an entire net income of not more than three hundred ninety thousand dollars for the taxable year; (ii) the aggregate amount of money and other property received by the corporation for stock, as a contribution to capital, and as paid-in surplus, does not exceed one million dollars; (iii) which is not part of an affiliated group, as defined in section 1504 of the internal revenue code, unless such group, if it had filed a report under this article on a combined basis, would have itself qualified as a "small business taxpayer" pursuant to this subdivision; and (iv) which has an average number of individuals, excluding general executive officers, employed full-time in the state during the taxable year of one hundred or fewer. If the taxable period to which subparagraph (i) of this paragraph applies is less than twelve months, entire net income under such subparagraph shall be placed on an annual basis by multiplying the entire net income by twelve and dividing the result by the number of months in the period. For purposes of subparagraph (ii) of this paragraph, the amount taken into account with respect to any property other than money shall be the amount equal to the adjusted basis to the corporation of such property for determining gain, reduced by any liability to which the property was subject or which was assumed by the corporation. The determination under the preceding sentence shall be made as of the time the property was received by the corporation. For purposes of subparagraph (iv) of this paragraph, "average number of individuals, excluding general executive officers, employed full-time" shall be computed by ascertaining the number of such individuals employed by the taxpayer on the thirty-first day of March, the thirtieth day of June, the thirtieth day of September and the thirty-first day of December during each taxable year or other applicable period, by adding together the number of such individuals ascertained on each of such dates and dividing the sum so obtained by the number of such dates occurring within such taxable year or other applicable period. An individual employed full-time means an employee in a job consisting of at least thirty-five hours per week, or two or more employees who are in jobs that together constitute the equivalent of a job at least thirty-five hours per week (full-time equivalent). Full-time equivalent employees in the state include all employees regularly connected with or working out of an office or place of business of the taxpayer within the state. 1-c. The computations specified in paragraph (b) of subdivision one of this section shall not apply to the first two taxable years of a taxpayer which, for one or both such years, is a small business taxpayer as defined in paragraph (f) of subdivision one of this section. 2. The amount of investment capital and business capital shall each be determined by taking the average value of the assets included therein (less liabilities deductible therefrom pursuant to the provisions of subdivisions five and seven of section two hundred eight), and, if the period covered by the report is other than a period of twelve calendar months, by multiplying such value by the number of calendar months or major parts thereof included in such period, and dividing the product thus obtained by twelve. For purposes of this subdivision, real property and marketable securities shall be valued at fair market value and the value of personal property other than marketable securities shall be the value thereof shown on the books and records of the taxpayer in accordance with generally accepted accounting principles. 3. A corporation that is a partner in a partnership shall compute tax under this article using the aggregate method as defined in the regulations of the commissioner, unless another method for computing such tax is required or allowed by such regulations. Under the aggregate method, a corporation that is a partner in a partnership is viewed as having an undivided interest in the partnership's assets, liabilities, and items of receipts, income, gain, loss and deduction. Under the aggregate method, the corporation that is a partner in a partnership is treated as participating in the partnership's transactions and activities.
