Child maintenance: how it is calculated under the 2012 CMS scheme (UK excluding NI)

Published Monday, September 23, 2019

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.

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).
