(1) A specific minimum contribution toward child support should be ordered in all cases when the parent's income, after deductions, is less than or equal to the parent's personal allowance or the parent's calculated child support obligation is less than 12% of that parent's income after deductions.

(a) For parents whose income, as defined in ARM 37.62.105 and ARM 37.62.106, after deductions, as defined in ARM 37.62.110, is less than or equal to the parent's personal allowance, the minimum contribution is a portion of the income after deductions and is determined by applying the table in (3) as follows:

(i) divide the income after deductions by the personal allowance as defined in ARM 37.62.114 to determine the income ratio;

(ii) find the income ratio in Column A;

(iii) locate the corresponding minimum contribution multiplier in Column B; and

(iv) multiply the income after deductions by the minimum contribution multiplier. The result is the parent's minimum contribution.

(b) For parents whose income after deductions exceeds the personal allowance, the parent's minimum contribution is 12% of income after deductions.

(2) The minimum contributions under this rule are presumptive and may be rebutted by the circumstances of a particular case, provided there is an appropriate finding on the record.

(3) The table for determining the minimum support obligation of a parent whose income after deductions is less than or equal to the parent's personal allowance is as follows:
