Is child maintenance taxable?
No. Child maintenance payments are completely exempt from income tax in the UK. If you receive child maintenance - whether through the CMS or a private arrangement - you do not need to declare it to HMRC, and you will not pay tax on it.
Does the receiving parent pay tax on maintenance?
No. Child maintenance received is not counted as income for any tax purpose. It does not appear on your Self Assessment tax return, and it does not affect your tax code.
Can the paying parent claim tax relief?
No. Child maintenance payments are not tax-deductible for the paying parent. You cannot offset them against your income or claim them as a business expense. This applies regardless of whether you pay through the CMS or a private arrangement.
Does child maintenance count as income for Universal Credit?
No. Child maintenance is completely disregarded for Universal Credit calculations. Receiving maintenance will not reduce your Universal Credit payments. See our full guide: Does child maintenance affect benefits?
Does child maintenance affect Child Benefit?
No. Receiving or paying child maintenance does not affect your Child Benefit entitlement. Child Benefit is assessed separately based on income, and maintenance payments are not part of that calculation.
