37.—(1) The amount to be deducted in respect of income tax under regulation 36(1)(b)(i), (2)(b)(i) or (8)(a)(i) (calculation of net profit of self-employed earners) must be calculated on the basis of the amount of chargeable income and as if that income was assessable to income tax at the basic rate of tax applicable to the assessment period less only the personal relief to which the applicant is entitled under sections 36 or 37 of the Income Tax Act 2007(1) (personal allowances) as is appropriate to the applicant’s circumstances, but if the assessment period is less than a year the earnings to which the basic rate of tax is to be applied and the amount of the personal reliefs deductible under this paragraph must be calculated on a pro rata basis.
(2) The amount to be deducted in respect of social security contributions under regulation 37(1)(b)(i), (2)(b)(ii) or (8)(a)(ii) is the total of—
(a)the amount of Class 2 contributions payable under section 11(1) or, as the case may be, 11(3) of the 1992 Act at the rate applicable to the assessment period except where the applicant’s chargeable income is less than the amount specified in section 11(4) of that Act(2) (small earnings exception) for the tax year applicable to the assessment period, but if the assessment period is less than a year the amount specified for that tax year must be reduced pro rata; and
(b)the amount of Class 4 contributions (if any) which would be payable under section 15 of the 1992 Act(3) at the percentage rate applicable to the assessment period on so much of the chargeable income as exceeds the lower limit but does not exceed the upper limit of profits and gains applicable for the tax year applicable to the assessment period, but if the assessment period is less than a year those limits must be reduced pro rata.
(3) In this regulation “chargeable income” means—
(a)except where sub-paragraph (b) applies, the earnings derived from the employment less any expenses deducted under regulation 36(2)(a) or (3) (calculation of net profit of self-employed earners); and
(b)in the case of employment as a child minder, one third of the earnings of that employment.
