Foster Carer Tax UK 2026/27: Qualifying Care Relief Explained With a Worked Example
Foster carers benefit from Qualifying Care Relief, a generous fixed tax exemption that means most foster carers pay little or no tax on their fostering income. Full worked example on a typical single-child placement.
Why most foster carers pay little or no tax
Qualifying Care Relief is one of the most generous targeted reliefs in the UK tax system: it combines a substantial fixed annual tax-free exemption with an additional weekly tax-free amount for each child or young person in placement, and for the majority of foster carers — who typically care for one or two children at a time — this comfortably covers all or almost all of their fostering income, meaning little to no income tax is actually due.

Rather than deducting actual itemised expenses (which would be extremely fiddly given the nature of fostering costs), Qualifying Care Relief lets carers apply a simplified fixed exemption to their total fostering income for the year. Only income above the combined exemption (the fixed amount plus the per-child weekly rates for however many weeks each child was placed) is potentially taxable — and even then, carers can choose to calculate actual profit instead if that would produce a lower figure, though this is uncommon given how generous the standard exemption usually proves relative to typical fostering allowances received.

Even where tax owed ends up being nil, foster carers are still expected to register for Self Assessment as self-employed and file a return declaring fostering income and formally applying the relief — this isn't just paperwork for its own sake, since it establishes the record HMRC needs to confirm the exemption has been correctly claimed. Separately, because Class 2/4 National Insurance depends on actual taxable profit (which is often nil or very low under Qualifying Care Relief), foster carers should check their eligibility for National Insurance credits specifically available to protect State Pension entitlement during fostering years, since these need to be actively claimed rather than being applied automatically.
What to keep records of
- Total fostering allowance/payments received across the year, by child and placement
- Number of weeks each child was in placement
- Any additional fostering-related income (training payments, respite care fees)
Filing and paying
Register for Self Assessment as self-employed, keep placement and payment records to support the Qualifying Care Relief calculation, and file online by 31 January following the tax year end — even where the relief reduces the tax bill to nil.

What is Qualifying Care Relief?
Qualifying Care Relief is a specific tax exemption scheme for foster carers (and some other types of carer, such as those providing shared lives care) that lets carers earn fostering income up to a generous fixed exemption threshold, plus a further weekly amount per child in placement, completely tax-free — most foster carers with typical placement numbers pay little or no income tax on their fostering payments as a result.
Do foster carers need to register as self-employed?
Yes, foster carers are generally treated as self-employed for tax purposes and need to register for Self Assessment, even though most will owe little or no tax once Qualifying Care Relief is applied — registration and filing are still required to formally claim the relief each year.
What happens if fostering income exceeds the Qualifying Care Relief exemption?
If total fostering payments exceed the fixed exemption amount plus the per-child weekly amounts for the placements in the year, foster carers can choose between being taxed on the excess over the exemption (the simplified method), or calculating actual profit in the normal way (income minus actual expenses) if that produces a lower taxable figure — most carers with modest placement numbers find the simplified exemption method more favourable and much simpler.
Does Qualifying Care Relief also cover National Insurance?
Foster carers with fostering income below the Qualifying Care Relief threshold generally have a nil or very low profit figure, which affects Class 2/Class 4 National Insurance liability accordingly, but it's worth checking whether voluntary National Insurance credits or contributions are needed to protect State Pension entitlement in years where little formal profit is recorded.
Do foster carers get National Insurance credits even if they pay no tax?
Many foster carers are entitled to National Insurance credits for the years they're actively fostering, specifically to protect their State Pension record even where actual profit (and therefore Class 2/4 liability) is minimal — this needs to be claimed rather than applied automatically, so it's worth checking eligibility each year.
