What is the Child Maintenance Service (CMS)?

The Child Maintenance Service (CMS) is a government service that calculates, manages, and enforces child maintenance payments between separated parents.

How are child maintenance payments calculated?

Payments are calculated using the paying parent’s gross weekly income, the number of children, and how often the child stays overnight.

What income does CMS use for calculations?

CMS uses gross income information provided by HMRC, including earnings from employment and self-employment.

What happens if the other parent does not pay child maintenance?

CMS has powers to recover unpaid maintenance, including deductions from earnings, bank accounts, or legal enforcement action.

What is a Direct Pay arrangement?

Direct Pay is when both parents arrange and manage child maintenance payments between themselves without CMS handling the money.

What is Collect and Pay?

Collect and Pay is a service where CMS collects payments from one parent and sends them to the other, usually when payments are not made voluntarily.

Can I challenge a CMS decision?

If you disagree with a decision, you can ask CMS to review it and, if needed, take the matter further through the appropriate process.

How long does CMS take to process a case?

Processing times can vary, but cases are usually set up within a few weeks depending on how quickly information is provided.

Can a CMS case be closed?

In some situations, a case can be closed or arrangements changed, depending on the circumstances and agreements between parents.

What happens if payments are missed?

Missed payments can lead to enforcement action, depending on how the case is set up and managed.

Do I pay tax on child maintenance?

Child maintenance payments are not treated as taxable income.

How can I contact CMS?

CMS can be contacted online or by phone to manage your case, report issues, or request further information.
