“the ‘drawdown’ system…is set up in such a way that only one request can be made per year. This is to prevent that original benchmark ‘historic income’ figure from being changed over the course of the following year (prior to the next child maintenance review date). This should not normally happen as the 2012 scheme is designed specifically so that there are long term (i.e. of at least a year) assessments in place, except in prescribed circumstances, e.g. where there is a significant change of income (25% or more).” (e) there must, however, be provision for further requests for HMRC figures where “there is good reason to doubt the validity of the figure provided by HMRC”
“(2) The non-resident parent's gross weekly income is to be based on historic income unless— (a) current income differs from historic income by an amount that is at least 25% of historic income; or (b) no historic income is available; or (c) the Secretary of State is unable, for whatever reason, to request or obtain the required information from HMRC. SB v (1) Secretary of State for Work and Pensions, (2) TB (CSM)[2016] UKUT 0084 (AAC) CCS/2082/2015 7 …(3) For the purposes of paragraph (2)(b) no historic income is available if HMRC did not, when a request was last made by the Secretary of State for the purposes of regulation 35, have the required information in relation to a relevant tax year”
“(1) Historic income is determined by- (a) taking the HMRC figure last requested from HMRC in relation to the non-resident parent; (b) adjusting that figure where required in accordance with paragraph (3) [which concerns “relievable pension contributions”]; and (c) dividing by 365 and multiplying by 7.”
“A request for the HMRC figure is to be made by the Secretary of State- (a) for the purposes of a decision under section 11 of the 1991 Act (the initial maintenance calculation) no more than 30 days before the initial effective date; and (b) for the purposes of updating that figure, no more than 30 days before the review date.”
“The HMRC figure is the amount identified by HMRC from information provided in a self-assessment return or under the PAYE regulations, as the sum of the income on which the non-resident parent was charged to tax for the latest available tax year- (a) under Part 2 of ITEPA (employment income); (b) under Part 9 of ITEPA (pension income); SB v (1) Secretary of State for Work and Pensions, (2) TB (CSM)[2016] UKUT 0084 (AAC) CCS/2082/2015 8 (c) under Part 10 of ITEPA (social security income) but only in so far as that income comprises the following taxable UK benefits listed in Table A in Chapter 3 of that Part- - (i) incapacity benefit; (ii) contributory employment and support allowance; (iii) jobseeker's allowance; and (iv) income support; and (d) under Part 2 of ITTOIA (trading income).”
“(1) In these Regulations “latest available tax year” means the tax year which, on the date on which the Secretary of State requests information from HMRC for the purposes of regulation 35 (historic income)…is the most recent relevant tax year for which HMRC have received the information required to be provided in relation to the non-resident parent under the PAYE Regulations or in a self-assessment return. (2) In this regulation a “relevant tax year” is any one of the 6 tax years immediately preceding the date of the request for information referred to in paragraph (1).”
“If an appeal under this section is allowed, the First-tier Tribunal may— (a) itself make such decision as it considers appropriate; or (b) remit the case to the Secretary of State, together with such directions (if any) as it considers appropriate.”
