|(a) Texas Labor Code §203.105, V.T.C.A. provides that the Commission shall collect an unemployment obligation assessment, also referred to as an assessment, from each employer eligible for an experience tax rate if, after January 1 of a year, an interest payment on an advance from the federal trust fund will be due and the estimated amount necessary to make the interest payment is not available in the obligation trust fund or available otherwise; or bond obligations are due and the amount necessary to pay in full those obligations, including bond administrative expenses, is not available in the obligation trust fund or available otherwise. (b) When the Commission determines that an assessment as referred to in the paragraph above will be due after January 1 of a year, the Commission shall compute the assessment rate using the formulas set out below in this section, before November 20th of the year prior to the year of the assessment. This rate shall be published in the Texas Register. (c) The calculation for the unemployment obligation assessment rate is the sum of subsection (d) and (e) of this section. (d) The rate for the portion of the assessment that is to be used to pay an interest payment on federal loans shall not exceed two tenths of one percent. The rate shall be calculated by dividing two hundred percent (200%) of the additional amount estimated to be needed to pay interest due, as determined by the Agency, by the estimated total taxable wages for the 1st and 2nd quarters of the year in which the interest is due, and rounded up to the next hundredth. (e) The rate for the portion of the assessment that is to be used to pay a bond obligation is a percentage of the product of the unemployment obligation assessment ratio and the sum of the employer's prior year general tax rate, the replenishment tax rate and the deficit tax rate. The percentage, to be determined by Commission resolution, shall not exceed 200%. (1) The Unemployment Obligation Assessment Ratio is computed by: (A) dividing the numerator computed under paragraph (2) of this subsection by the denominator described in paragraph (3) of this subsection; and (B) rounding that result up to the next hundredth. (2) The numerator is computed by adding the total principal, interest and administrative expenses on all outstanding bonds determined to be due during the next year. However, if the Commission determines that there will be excess funds available in the obligation trust fund that are not anticipated to be expended for the purposes set out in Texas Labor Code, §203.258 (2)-(4), the numerator may be reduced by the amount of that excess. (3) The denominator is the amount of contributions due under the general tax rate and the replenishment tax rate for the four calendar quarters ending the preceding June 30 from employers entitled to an experience rate on the tax rate computation date.
