An eligible individual who is partially unemployed throughout a week, which shall be, at the discretion of the administrator, either a calendar week or a payroll week of seven consecutive days as determined by the administrator, shall be paid with respect to such week an amount equal to his benefit rate for total unemployment reduced by an amount equal to two-thirds, rounded to the next higher whole dollar, of the total remuneration, rounded to the nearest whole dollar, of any nature payable to him for services of any kind during such week, except service performed in the employ of any town, city or other political subdivision, which service is performed in lieu of payment of any delinquent tax payments to such town, city or other political subdivision. An individual shall be deemed to be partially unemployed in any week of less than full-time work if the total remuneration of any nature payable to him for services of any kind during such week, except service performed in the employ of any town, city or other political subdivision, which service is performed in lieu of payment of any delinquent tax payments to such town, city or other political subdivision, amounts to less than one and one-half times his benefit rate for total unemployment rounded to the next highest dollar. For purposes of this section, remuneration shall also include any holiday pay payable with respect to any such week, whether or not any service was performed during such week or was in any other way required for receipt of such holiday pay. For purposes of this section, the administrator shall consider earnings derived from self-employment, but only to the extent such earnings are actually received or payable with respect to a given week of partial unemployment.
