Kinship Carer & Special Guardianship Allowance Tax UK 2026/27: What's Taxable, What Isn't
Grandparents and relatives raising a child under a Special Guardianship Order or informal kinship arrangement often receive an allowance from the local authority — here's how it's taxed, what benefits you can still claim, and a worked example.
Kinship care: an overlooked but growing group
An estimated 130,000-200,000 children in the UK are raised by relatives — grandparents, aunts, uncles, older siblings — outside the formal care system, in what's collectively known as kinship care. Some arrangements are entirely informal (a grandparent simply steps in when a parent can't cope), while others follow a court process resulting in a Special Guardianship Order (SGO) or Child Arrangements Order, which can come with formal local authority support including a means-tested allowance.
Understanding what's taxable, what benefits remain available, and how the financial support interacts is genuinely confusing — kinship carers often fall through gaps between the foster care system (which has clear, well-publicised tax rules) and ordinary parenting (where most families simply claim Child Benefit and get on with it).
Is the Special Guardianship Allowance taxed?
Local authorities can pay a Special Guardianship Allowance to support a guardian raising a child under an SGO, calculated (in most areas) on a similar basis to the fostering allowance or adoption allowance, and typically means-tested against the guardian's own income and the child's other means (such as any child maintenance received). In most cases, this allowance is not treated as taxable income — it's viewed as a payment to support the child's welfare rather than income to the carer, broadly analogous to how fostering payments are largely covered by the tax-free Qualifying Care Relief scheme for registered foster carers.
However, the exact tax treatment can depend on how the specific local authority structures the payment, and kinship carers with other income (particularly self-employment) should confirm their situation directly with HMRC or an accountant rather than assume, since getting this wrong on a Self Assessment return (if you already file one for other reasons) could create complications.

Whether or not a formal court order is in place, if you are the person with day-to-day responsibility for raising a child, you can claim Child Benefit in exactly the same way a birth parent would:
- First child: £27.05/week (£1,406.60/year) for 2026/27
- Each additional child: £17.90/week (£930.80/year) for 2026/27
Worked example: grandparent raising two grandchildren under an SGO
A grandmother becomes Special Guardian for her two grandchildren, aged 6 and 9, following care proceedings. She receives:
- Special Guardianship Allowance from the local authority (means-tested, let's assume £180/week for both children combined based on local rates and her modest pension income) — not taxable
- Child Benefit: £27.05 (first child) + £17.90 (second child) = £44.95/week (£2,337.40/year) — claimed as she would if the children were her own
- Her own State Pension and small part-time earnings remain taxed as normal, entirely separately from the above
Because her total income is well below £60,000, the High Income Child Benefit Charge doesn't affect her — she keeps the full Child Benefit amount.
The High Income Child Benefit Charge still applies
If a kinship carer (or their partner) has individual income above £60,000, the same High Income Child Benefit Charge that applies to any parent kicks in — clawing back 1% of the Child Benefit for every £200 of income above £60,000, reaching a full 100% clawback at £80,000. This is more relevant for higher-earning relative carers (an aunt or uncle in professional employment, for example) than for many grandparent carers on fixed retirement incomes, but the rule doesn't distinguish based on the family relationship — it applies identically.
Universal Credit and means-tested support
Kinship carer households can claim Universal Credit, Council Tax Reduction and other means-tested benefits exactly as any household with children can, with the child counted within the benefit unit. Because the Special Guardianship Allowance is itself often means-tested against the carer's income, and Universal Credit is also means-tested, the interaction between the two needs careful handling — claiming both isn't automatically double-counted against you, but the specific rules depend on how income is assessed in each scheme. Kinship care charities (Kinship, Family Rights Group) and Citizens Advice both offer specialist guidance on navigating this combination, and it's worth seeking that advice given how easy it is to either under-claim or inadvertently create an overpayment.

Where a relative steps in without going through a court process — the most common form of kinship care, often arranged quickly in a crisis — there is generally no automatic local authority allowance. The carer can still claim Child Benefit and household means-tested benefits (Universal Credit, Council Tax Reduction) based on the child living with them, but the more structured Special Guardianship support (allowance, assessed needs, ongoing local authority involvement) typically isn't available unless and until a formal order is obtained. This is one of the reasons kinship care charities encourage informal carers to seek legal advice about whether pursuing a Child Arrangements Order or Special Guardianship Order would unlock additional support, even where the immediate care arrangement feels settled and workable without one.
uk-carer-allowance-complete-guide-2026Frequently asked questions
Is a Special Guardianship Allowance taxable income?
Generally no. Special Guardianship Allowances paid by a local authority are means-tested payments to support the child's upbringing, and in most cases are not treated as taxable income for the guardian, similar to fostering allowances under the Qualifying Care Relief regime, though the exact treatment can depend on the local authority's specific payment structure. If you receive a significant allowance, it's worth confirming the tax treatment with HMRC or an accountant, particularly if you also have other self-employment income.
Can kinship carers claim Child Benefit for the child they're raising?
Yes. If you are responsible for raising a child (including under a Special Guardianship Order, Child Arrangements Order, or informal kinship arrangement where you have day-to-day care), you can claim Child Benefit in the same way a parent would — £27.05/week for the first child and £17.90/week for each additional child in 2026/27. If your own income (or your partner's) exceeds £60,000, the High Income Child Benefit Charge may apply.
What is the High Income Child Benefit Charge and does it apply to kinship carers?
Yes, the same rules apply regardless of whether you're a birth parent, adoptive parent or kinship carer. If your or your partner's individual income exceeds £60,000, part of the Child Benefit is clawed back via a tax charge, rising to a full clawback at £80,000. Many kinship carers are grandparents on modest fixed incomes who are unaffected by this, but it's relevant for higher-earning relative carers.
Do kinship carers qualify for Universal Credit or other means-tested benefits?
Potentially yes — kinship carers can claim Universal Credit, Council Tax Reduction and other means-tested support on the same basis as any household, with the child counted as part of the benefit household. Special Guardianship Allowance itself is often means-tested against other income, so claiming both together needs care to understand how one affects the other — a local Kinship Care support service or Citizens Advice can help navigate this.
Can a kinship carer get National Insurance credits for time spent caring?
Yes, potentially via Carer's Credit or, in some cases, the Specified Adult Childcare credit if a working-age relative is caring for a child under 12 so the child's parent can work — though this specific credit is designed around grandparents caring while a parent works, and its application to formal kinship/guardianship arrangements should be checked against current DWP guidance for your specific situation.
Is there a difference in allowance between informal kinship care and a Special Guardianship Order?
Yes, significantly. Formal Special Guardianship Orders (and Child Arrangements Orders following care proceedings) typically come with a means-tested local authority allowance, ongoing support entitlement, and access to an assessment of needs. Informal kinship care (a relative simply steps in without a court order) generally does NOT trigger any automatic local authority allowance, though the carer can still claim Child Benefit and household benefits like Universal Credit based on the child living with them.
