The taxpayer may, to the extent provided in this subsection and subsection (c), credit against the tax imposed by section 3301 the amount of contributions paid by him into an unemployment fund maintained during the taxable year under the unemployment compensation law of a State which is certified as provided in section 3304 for the 12-month period ending on October 31 of such year.

(1) The taxpayer may, to the extent provided in this subsection and subsection (c), credit against the tax imposed by section 3301 the amount of contributions paid by him into an unemployment fund maintained during the taxable year under the unemployment compensation law of a State which is certified as provided in section 3304 for the 12-month period ending on October 31 of such year.

(2) The credit shall be permitted against the tax for the taxable year only for the amount of contributions paid with respect to such taxable year.

(3) The credit against the tax for any taxable year shall be permitted only for contributions paid on or before the last day upon which the taxpayer is required under section 6071 to file a return for such year; except that credit shall be permitted for contributions paid after such last day, but such credit shall not exceed 90 percent of the amount which would have been allowable as credit on account of such contributions had they been paid on or before such last day.

(4) Upon the payment of contributions into the unemployment fund of a State which are required under the unemployment compensation law of that State with respect to remuneration on the basis of which, prior to such payment into the proper fund, the taxpayer erroneously paid an amount as contributions under another unemployment compensation law, the payment into the proper fund shall, for purposes of credit against the tax, be deemed to have been made at the time of the erroneous payment. If, by reason of such other law, the taxpayer was entitled to cease paying contributions with respect to services subject to such other law, the payment into the proper fund shall, for purposes of credit against the tax, be deemed to have been made on the date the return for the taxable year was filed under section 6071.

(5) In the case of wages paid by the trustee of an estate under title 11 of the United States Code, if the failure to pay contributions on time was without fault by the trustee, paragraph (3) shall be applied by substituting “100 percent” for “90 percent”.

In addition to the credit allowed under subsection (a), a taxpayer may credit against the tax imposed by section 3301 for any taxable year an amount, with respect to the unemployment compensation law of each State certified as provided in section 3303 for the 12-month period ending on October 31 of such year, or with respect to any provisions thereof so certified, equal to the amount, if any, by which the contributions required to be paid by him with respect to the taxable year were less than the contributions such taxpayer would have been required to pay if throughout the taxable year he had been subject under such State law to the highest rate applied thereunder in such 12-month period to any person having individuals in his employ, or to a rate of 5.4 percent, whichever rate is lower.

If an advance or advances have been made to the unemployment account of a State under title XII of the Social Security Act, then the total credits (after applying subsections (a) and (b) and paragraph (1) of this subsection) otherwise allowable under this section for the taxable year in the case of a taxpayer subject to the unemployment compensation law of such State shall be reduced—

(1) The total credits allowed to a taxpayer under this section shall not exceed 90 percent of the tax against which such credits are allowable.

If an advance or advances have been made to the unemployment account of a State under title XII of the Social Security Act, then the total credits (after applying subsections (a) and (b) and paragraph (1) of this subsection) otherwise allowable under this section for the taxable year in the case of a taxpayer subject to the unemployment compensation law of such State shall be reduced—

(A) (i) in the case of a taxable year beginning with the second consecutive January 1 as of the beginning of which there is a balance of such advances, by 5 percent of the tax imposed by section 3301 with respect to the wages paid by such taxpayer during such taxable year which are attributable to such State; and (ii) in the case of any succeeding taxable year beginning with a consecutive January 1 as of the beginning of which there is a balance of such advances, by an additional 5 percent, for each such succeeding taxable year, of the tax imposed by section 3301 with respect to the wages paid by such taxpayer during such taxable year which are attributable to such State;

(B) in the case of a taxable year beginning with the third or fourth consecutive January 1 as of the beginning of which there is a balance of such advances, by the amount determined by multiplying the wages paid by such taxpayer during such taxable year which are attributable to such State by the percentage (if any), multiplied by a fraction, the numerator of which is the State’s average annual wage in covered employment for the calendar year in which the determination is made and the denominator of which is the wage base under this chapter, by which— (i) 2.7 percent multiplied by a fraction, the numerator of which is the wage base under this chapter and the denominator of which is the estimated United States average annual wage in covered employment for the calendar year in which the determination is to be made, exceeds (ii) the average employer contribution rate for such State for the calendar year preceding such taxable year; and

(C) in the case of a taxable year beginning with the fifth or any succeeding consecutive January 1 as of the beginning of which there is a balance of such advances, by the amount determined by multiplying the wages paid by such taxpayer during such taxable year which are attributable to such State by the percentage (if any) by which— (i) the 5-year benefit cost rate applicable to such State for such taxable year or (if higher) 2.7 percent, exceeds (ii) the average employer contribution rate for such State for the calendar year preceding such taxable year.

For purposes of subparagraph (C) of subsection (c)(2), the 5-year benefit cost rate applicable to any State for any taxable year is that percentage obtained by dividing—

(A) one-fifth of the total of the compensation paid under the State unemployment compensation law during the 5-year period ending at the close of the second calendar year preceding such taxable year, by

In the case of any State which meets the requirements of paragraph (2) with respect to any taxable year the reduction under subsection (c)(2) in credits otherwise applicable to taxpayers subject to the unemployment compensation law of such State shall not exceed the greater of—

(A) the reduction which was in effect with respect to such State under subsection (c)(2) for the preceding taxable year, or

(B) 0.6 percent of the wages paid by the taxpayer during such taxable year which are attributable to such State.

In the case of a State which would meet the requirements of this subsection for a taxable year prior to 1986 but for its failure to meet one of the requirements contained in subparagraph (C) or (D) of paragraph (2), the reduction under subsection (c)(2) in credits otherwise applicable to taxpayers in such State for such taxable year and each subsequent year (in a period of consecutive years for each of which a credit reduction is in effect for taxpayers in such State) shall be reduced by 0.1 percentage point.
