Grandparents who did the school run so a daughter could work have earned something they were never told about. The Child Benefit that daughter claimed generated a National Insurance credit each week, and if she was working and paying her own contributions the credit was spare. Since 2011 it can be moved to the family member who provided the care, and it fills a year in their State Pension record for nothing.
Who qualifies
GOV.UK says you can apply for Specified Adult Childcare Class 3 credits if you are an eligible family member over 16 but under State Pension age and you have cared for a child under 12 at any time since 6 April 2011 (GOV.UK, Apply for Specified Adult Childcare credits, checked 1 November 2026).
The parent must be registered for Child Benefit. The age condition is about the weeks you cared: a grandparent now over State Pension age can still claim the years when she was under it.
The parent or main carer must be registered for Child Benefit for the child.
The credit is a transfer, not a new grant. Child Benefit for a child under 12 gives the person registered for it a Class 3 credit automatically, whether or not they receive the money (GOV.UK, National Insurance credits, checked 1 November 2026). Where that parent worked and has a qualifying year anyway, the credit does nothing for them and can go to the grandparent who made the work possible.
Why the wait until 31 October
GOV.UK says you must wait until 31 October after the end of the tax year you want to apply for, because HMRC needs to check that the parent or main carer already has a qualifying year (GOV.UK, Apply for Specified Adult Childcare credits, checked 1 November 2026). A year of caring that ended on 5 April 2026 can be claimed from 31 October 2026.
The check is the whole logic of the scheme. If the parent did not earn a qualifying year of their own, the credit is theirs and stays with them; there is nothing spare to move. A parent who worked part-time below the National Insurance threshold may need the credit, and the grandparent’s claim will fail for that year.
How far back
GOV.UK says these credits were introduced on 6 April 2011 and can be claimed from that date (GOV.UK, Apply for Specified Adult Childcare credits, checked 1 November 2026). There is no deadline stated for a past year, and a claim can cover every tax year since 2011 in which the conditions were met.
That reaches a grandmother now over State Pension age. The credit is for years in which she was under State Pension age and caring, whatever her age now, and each year claimed is a qualifying year added to a record that may have fallen short of the full pension. Our forecast page covers what a year adds, about £6.89 a week under the new rules.
The form, and the parent’s part
The form is CA9176. GOV.UK says to complete it, and the parent or main carer signs to confirm the care and that they agree to the credit being transferred (GOV.UK, Apply for Specified Adult Childcare credits, checked 1 November 2026). Only one credit exists for each week, so where two grandparents shared the care, or a grandparent and an aunt, one of them claims each week.
The form is a family conversation as much as a document. The parent needs to know that the transfer costs them nothing, because the check for their own qualifying year comes first, and that it is their signature that makes it work.
The parent-to-parent version
The same credit can move between the parents. GOV.UK says that if you are the spouse, partner or civil partner living with the Child Benefit recipient and want the credits transferred to yourself, you complete form CF411A (GOV.UK, Apply for Specified Adult Childcare credits, checked 1 November 2026).
That is for a household where the higher earner claimed Child Benefit and the parent at home has the gap.
Neither form is the Carer’s Credit form. Caring for a sick or disabled adult for 20 hours a week is a different credit, claimed on form CC1, on our Carer’s Credit page.
Checking it landed
GOV.UK’s National Insurance record service shows any credits you have received and whether gaps mean some years do not count (GOV.UK, Check your National Insurance record, checked 1 November 2026). A claimed year should appear there once HMRC has processed the form, and a year that still shows a gap is the reason to chase.
Where the year cannot be credited, because the parent needed it or the child was over 12, the alternative is paying for it, at £18.40 a week for Class 3 in 2026/27 (GOV.UK, Voluntary National Insurance, checked 1 November 2026), on our voluntary contributions page.
