This House of Commons Library briefing note sets out how the Child Maintenance Service (CMS) calculates the amount of child maintenance payable under the 2012 statutory child maintenance scheme. A link to the full report in pdf format can be found at the bottom of this page.Jump to full report >>
There are five different rates used to calculate the amount of child maintenance payable, with the rate applied depending on the non-resident parent’s gross weekly income, whether they (or their partner) claim certain welfare benefits, and the circumstances of the non-resident parent.
The standard method of calculating child maintenance does not take into account, for example, the taxable unearned income of the non-resident parent or certain expenses that a non-resident parent might incur. In such cases, an application for a “variation” can be made to the CMS – for more information, see the Library briefing paper Child maintenance: variations, including "unearned income" rules (UK excluding NI).
This note applies to Great Britain only (i.e. United Kingdom excluding Northern Ireland).
