Taxable gross annual income is the paying parent’s yearly income before Income Tax and National Insurance are taken off, but after occupational or personal pension scheme contributions are taken away.
Although you must tell CMS about changes that may affect the amount you have to pay, for example a change in income or benefits you get, the Annual Review is a different process.
See our document on the redress scheme for cohabiting couples.
In situations where parents or spouses/civil partners are separated, they can make informal agreements regarding maintenance.
Paying maintenance in itself give a parent access or guardianship rights.
Maintenance can be paid periodically (i.e., weekly or monthly) or in a lump sum.A divorcing parent may have to pay retroactive child support for the months between the start of the divorce and when the court actually issues a child support order.Past due support, also called “back” child support, results from one parent’s failure to pay court-ordered child support on time.This will depend on whether or not you have already contacted the Child Support Agency or Child Maintenance Service.Although you have mentioned 'maintenance' in your question, this can be by agreement or by court order so I will answer as though firstly you have put in a claim with the CSA/CMS and secondly as though you haven’t already put in a claim.
