A paying parent may still owe child maintenance when receiving benefits. Certain qualifying benefits normally result in a Flat rate of £7 per week, while specified circumstances can produce a Nil-rate decision. Receiving Universal Credit does not automatically establish either result. If you receive child maintenance rather than pay it, those payments do not normally reduce your Universal Credit or other benefits.
How Does Child Maintenance Work When You Receive Benefits?
Child maintenance provides financial support towards the living costs of children whose parents do not live together. Both employed and unemployed parents can have maintenance responsibilities.
When a parent uses the Child Maintenance Service (CMS), the amount payable is assessed using relevant gross income, qualifying benefits and other circumstances. The ordinary income bands do not cover every benefit-related case.
For some qualifying benefits, CMS uses a fixed Flat rate instead of the percentage normally used for employment earnings. In other specific cases, a Nil rate may apply.
The rules also distinguish between someone who receives child maintenance and someone who pays it. Receiving maintenance has a different impact on benefits from having an outstanding maintenance liability.
Important: A benefit claim does not always mean maintenance is £7 or £0. The type of benefit, income information and statutory conditions must be checked.
Paying Parent vs Receiving Parent: Why the Difference Matters
Benefit-related child maintenance questions often have two different meanings. One parent may want to know how much they must pay, while another wants to know whether receiving maintenance will reduce their benefits.
Yes. CMS considers qualifying benefits, relevant income and other circumstances to determine whether a Flat, Nil or income-based rate applies.
No. Child maintenance received does not normally reduce Universal Credit or other benefits received by the parent and child.
It is important to establish which situation applies before using any maintenance example. The rules for receiving financial support should not be confused with the paying parent's CMS liability.
Universal Credit and Child Maintenance
Universal Credit supports eligible people with living costs. It may be received by a parent who pays child maintenance or by the parent caring for the child.
Does Receiving Child Maintenance Affect Universal Credit?
No. Child maintenance payments received by a parent do not reduce their Universal Credit. These maintenance payments are also not subject to Income Tax.
For example, a receiving parent who gets Universal Credit and £80 a week in child maintenance does not normally have their Universal Credit reduced by that maintenance income.
Does Claiming Universal Credit Mean I Pay Only £7 Maintenance?
Not automatically. Universal Credit alone should not be assumed to qualify a paying parent for the Flat rate. CMS considers the applicable income and benefit rules to determine the correct maintenance liability.
A parent receiving Universal Credit might also have earnings, self-employed income or other relevant circumstances. These can affect the assessment.
Do not select the £7 Flat rate solely because the paying parent receives Universal Credit. Check the qualifying benefit and relevant income conditions or obtain an official CMS assessment.
Can Child Maintenance Arrears Affect Universal Credit?
In certain circumstances, deductions for child maintenance arrears may be taken from Universal Credit. This is different from the treatment of maintenance received by a parent.
Deductions depend on the applicable legal rules and the person's circumstances.
Read Official Universal Credit Guidance →Which Benefits Can Affect the CMS Flat Rate?
The official CMS calculation guide identifies certain benefits that can result in a £7 weekly Flat-rate maintenance assessment.
Some benefits qualify where the paying parent receives them directly. Certain income-related benefits received by their cohabiting partner can also be relevant.
Examples of Benefits Listed in Official CMS Guidance
| Benefit | General CMS Treatment |
|---|---|
| Income-related Employment and Support Allowance | Can lead to Flat-rate treatment, including certain partner claims |
| Contribution-based Employment and Support Allowance | Listed as a qualifying Flat-rate benefit |
| Contribution-based Jobseeker's Allowance | Listed as a qualifying Flat-rate benefit |
| Pension Credit | Can lead to Flat-rate treatment, including certain partner claims |
| State Pension | Listed in the official Flat-rate benefit rules |
| Carer's Allowance | Listed as a qualifying Flat-rate benefit |
| Maternity Allowance | Listed as a qualifying Flat-rate benefit |
| Specified war, bereavement and incapacity benefits | Some payments qualify under detailed CMS rules |
This table is not a complete statutory benefits list. The official guidance also identifies additional specified allowances, pensions and other benefit categories.
Check the exact benefit: Benefit names can look similar while their CMS treatment differs. The official benefit category and eligibility conditions matter more than the general description of being on benefits.
What Is the £7 Child Maintenance Flat Rate?
The Flat rate is a fixed weekly amount used in specified child maintenance cases. The general Flat rate is £7 per week.
It can apply when relevant gross weekly income is between £7 and £100, or where the paying parent satisfies the conditions for a qualifying benefit.
Is the Flat Rate £7 Per Child?
No. In an ordinary qualifying benefit case, the £7 is generally one combined weekly Flat-rate amount, regardless of how many children are included in the assessment.
Example: Qualifying Benefit Case
Qualifying children: 3
Applicable CMS rate: Flat
General Flat-rate liability: £7 per week in total
This total can sometimes be reduced further if the Flat rate arises from qualifying benefits and the relevant shared-care conditions are met.
What If the Flat Rate Is Based on Low Income?
If the Flat rate applies because gross weekly income is £100 or less, rather than because of a qualifying benefit, shared care does not normally reduce the £7 amount.
When Does the Nil Rate Apply to Child Maintenance?
The Nil rate means the paying parent has a £0 weekly maintenance liability under the applicable CMS assessment.
The general Nil-income threshold is relevant gross weekly income below £7. However, some circumstances qualify for Nil-rate treatment for reasons other than income.
Examples of Nil-Rate Circumstances
- Relevant gross weekly income is below £7.
- The paying parent is under 16.
- The paying parent is in prison.
- Certain eligible 16-to-19-year-olds are in full-time non-advanced education or approved training.
- Specified care-home or independent-hospital circumstances apply.
A parent who is unemployed may receive benefits or have relevant income. CMS must assess the actual circumstances before deciding whether Flat, Nil or another rate applies.
Existing arrears may remain payable even where an ongoing assessment changes to the Nil rate.
What If You Receive Benefits and Also Have Earnings?
A paying parent may work part-time, receive a pension or earn self-employment income while claiming a benefit.
The outcome depends on the type of benefit, relevant weekly income and any additional-income variation.
Ordinary Income-Based Rates
| Relevant Weekly Income | General Rate | Starting Calculation |
|---|---|---|
| Below £7 | Nil | £0 |
| £7–£100 | Flat | Generally £7 |
| Above £100, below £200 | Reduced | £7 plus an applicable percentage above £100 |
| £200–£800 | Basic | 12%, 16% or 19% |
| Above £800, up to £3,000 | Basic Plus | Two percentage bands |
Qualifying benefits can alter the usual income-band result. For example, where a benefit-based Flat rate applies, CMS may need to consider additional earnings through a formal variation.
Additional Income Variations
In qualifying Flat-rate benefit cases, relevant employment, self-employment or pension income of at least £100 gross weekly may be considered through an additional-income variation.
CMS considers the evidence and applicable statutory rules. A higher payment is not automatically imposed simply because a parent receives both earnings and benefits.
Read Official Variation Rules →Does Shared Care Reduce Child Maintenance When on Benefits?
The answer depends on why the Flat rate applies and which care arrangements CMS accepts as qualifying.
Qualifying Benefit-Based Flat Rate
Where the Flat rate applies because a paying parent receives a qualifying benefit, at least 52 agreed overnight stays per year can reduce maintenance to £0 for that child.
This can also affect maintenance for other children living in the same household as that child.
Example: Benefit-Based Flat Rate
Starting Flat rate: £7 weekly
Qualifying overnight stays: 52 or more per year
Applicable benefit-based shared-care rule applies
Flat Rate Due to Low Income
If the Flat rate is based on gross weekly income of £100 or less and not on a qualifying benefit, ordinary overnight stays do not reduce that Flat-rate amount.
Reduced and Basic Rates
Where an income-based Reduced, Basic or Basic Plus rate applies, qualifying overnight care generally uses the following bands.
| Agreed Nights Per Year | General Reduction |
|---|---|
| 0–51 | No reduction |
| 52–103 | 1/7 |
| 104–155 | 2/7 |
| 156–174 | 3/7 |
| 175 or more | 50% plus an additional £7 weekly deduction for the relevant child |
In applicable Reduced, Basic and Basic Plus cases, the total maintenance cannot normally fall below £7 weekly after shared-care reductions.
Shared-care distinction: The £7 minimum for ordinary income-based calculations should not be confused with the special £0 outcome for qualifying benefit-based Flat-rate cases.
Can Child Maintenance Be Deducted from Benefits?
Yes. In certain cases, CMS can arrange deductions from specified benefits or pensions to collect child maintenance.
Where a qualifying benefit creates a Flat-rate liability, the weekly maintenance may normally be collected directly from the benefit.
The benefit received by the paying parent or their partner may therefore be lower after an authorised deduction.
What If CMS Cannot Deduct from the Benefit?
Some benefits are excluded from direct collection, and existing deductions may prevent another deduction from being made.
In such cases, CMS may need to arrange another appropriate payment method.
What About Maintenance Arrears?
CMS can also use specified benefit deductions to recover qualifying unpaid maintenance.
Arrears deductions are governed by different rules from the ordinary weekly maintenance calculation. They should not be confused with the Flat rate.
A new Flat or Nil assessment does not automatically cancel previous maintenance arrears. Contact CMS about an existing debt or deduction.
Are CMS Collection Fees Charged When Receiving Benefits?
CMS has different payment arrangements. The collection fees depend on the service used, not simply on whether the paying or receiving parent claims benefits.
Direct Pay
CMS calculates the amount, while the paying parent pays the receiving parent directly. No CMS collection fees apply.
Collect and Pay
CMS collects maintenance from the paying parent and transfers it to the receiving parent. Regular collection fees apply to this service.
| CMS Service | Paying Parent | Receiving Parent |
|---|---|---|
| Direct Pay | No collection fee | No collection fee |
| Collect and Pay | 20% added | 4% deducted |
A person with payments deducted directly from a benefit may be subject to specific collection arrangements. Consult the CMS Payment Plan for the actual amount due.
Compare CMS Payment Methods →Will Child Maintenance Affect My Benefits as a Single Parent?
Child maintenance received by a parent does not normally affect benefits that the parent or child receives, including Universal Credit.
This means maintenance payments can provide additional financial support towards a child's living costs without directly reducing Universal Credit.
Is Child Maintenance Taxable?
Child maintenance received is not subject to Income Tax.
Do I Need to Be Working to Receive Child Maintenance?
No. The receiving parent's employment status does not normally determine whether they can receive child maintenance.
Eligibility and the amount payable depend on the relevant child maintenance arrangement and statutory rules.
Example: If you receive £75 weekly maintenance and Universal Credit, the maintenance received does not normally reduce your Universal Credit entitlement.
What Happens If Your Benefits or Income Change?
Maintenance liability can change when relevant income or qualifying benefit circumstances change.
CMS normally reviews ongoing assessments annually, but some changes must be reported earlier.
Changes That May Need Reporting
- Starting or stopping a qualifying benefit.
- Employment or self-employment income changing significantly.
- Becoming eligible for a Nil rate.
- Relevant changes to a partner's qualifying benefit circumstances.
- Changes to overnight care arrangements.
- A child ceasing to meet maintenance eligibility requirements.
Some current-income reassessments involve a 25% threshold, but this is not a universal condition for all changes.
If an existing CMS assessment applies, continue following the payment plan until an authorised change takes effect. Report relevant changes promptly.
Child Maintenance on Benefits: Worked Examples
These examples illustrate different outcomes. They should not be taken as an assessment of any individual's benefit eligibility.
Example 1: Qualifying Benefit and One Child
CMS confirms that a qualifying benefit-based Flat rate applies.
Children covered: 1
No qualifying shared-care reduction applies.
Example 2: Qualifying Benefit and Three Children
CMS confirms a qualifying benefit-based Flat-rate assessment.
Children covered: 3
The Flat rate is not automatically multiplied by three.
Example 3: Low Weekly Income
Relevant gross weekly income: £150
Children: 1
No qualifying benefit overrides the ordinary Reduced-rate calculation.
£7 + (£50 × 17%) = £15.50
Example 4: Universal Credit and Earnings
Paying parent receives Universal Credit and has £400 of relevant gross weekly income.
If CMS determines that the ordinary Basic rate applies for one child, the calculation is £400 × 12%.
The Universal Credit example does not assume that Universal Credit itself creates a Flat rate. An official assessment is necessary where benefit treatment is uncertain.
How to Check Child Maintenance When You Receive Benefits
The correct calculation starts with identifying which benefit you receive, whether you are the paying or receiving parent and what income is relevant.
Are you paying maintenance or receiving it?
Confirm the benefit name and relevant award details.
Consider employment earnings, other children and relevant adjustments.
Establish whether CMS uses a Flat, Nil, Reduced or income-based rate.
Confirm whether a qualifying overnight reduction is available.
Confirm payment amounts and any deductions with the relevant CMS authority.
Calculator limitation: Our homepage calculator may not support every qualifying benefit, special Flat-rate deduction or variation. Refer to CMS for an official benefit-based assessment.
