Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, for what reasons regulation 4(1) of the Child Support (Child Support Maintenance) Calculations Regulations 2012 provides that a relevant tax year for the calculation of child maintenance by a paying parent is any one of the six years immediately preceding the date of request and not the most recent year for which tax data is available.
