Number for Family Allowance: HMRC Phone Guide 2026

If you are looking for the number for Family Allowance, the benefit you need is now called Child Benefit. GOV.UK lists the official HMRC Child Benefit helpline as 0300 200 3100.

These contact details are published by HMRC on GOV.UK. Telephone opening arrangements and service availability can change, so check the GOV.UK Child Benefit contact page before calling.

Call the helpline if a payment appears to be missing, HMRC has written to you about an existing claim, or your circumstances cannot be updated through the digital service. For routine tasks, the GOV.UK online Child Benefit service may be quicker and creates a clearer record of the information supplied.

• Use the online service: to start a claim, report an eligible change or access the Child Benefit functions offered through your HMRC account.
• Call HMRC: if you need an explanation of a decision, cannot use the digital route or have a payment-specific problem.
• Write to HMRC: where HMRC requests documents or a formal written response; use the address shown on the relevant GOV.UK page or HMRC letter.

Before calling, have your National Insurance number, recent HMRC correspondence and relevant payment details available. Do not post original documents unless HMRC specifically asks for them.

If household income has fallen while a payment issue is investigated, check wider entitlement using SupportFund’s benefits calculator guide and review Universal Credit support. Child Benefit and Universal Credit are separate schemes administered under different rules.

“Family Allowance” is not the current official name of the payment. HMRC administers Child Benefit, so searching or asking for the Child Benefit Office will lead you to the correct service.

Child Benefit is normally claimed by one person responsible for a child. GOV.UK explains that claiming can provide National Insurance credits towards the State Pension where the claimant is eligible, even if the household chooses not to receive payments because of the High Income Child Benefit Charge.

Practical point: Do not assume that opting out of payments is the same as having no claim. GOV.UK advises that registering a claim may protect qualifying National Insurance credits and can help ensure a child receives a National Insurance number automatically.

Tax liability under the High Income Child Benefit Charge depends on adjusted net income and household circumstances. Check the current HMRC rules on GOV.UK or obtain professional tax advice rather than relying on an old threshold quoted in a forum or archived article.

First compare the payment reference and date with your bank statement and latest HMRC correspondence. A changed bank account, altered care arrangement or unresolved eligibility query can affect how HMRC handles a claim.

1. Write down the claimant’s full name, address and National Insurance number.
2. Note the date and reference of the last Child Benefit payment received.
3. Gather any letters about changes in childcare, education, training or responsibility for the child.
4. Call 0300 200 3100, the number published by HMRC on GOV.UK, and record the date of the conversation.
5. Ask what action is required, where documents should be sent and when you should follow up.

If the missing payment leaves you unable to buy food or meet an essential bill, contact your local council about current crisis assistance and see emergency household help. In England, the former Household Support Fund ended on 31 March 2026 and was replaced from 1 April 2026 by the Crisis and Resilience Fund, according to GOV.UK; availability and application arrangements are set locally.

Support differs across England, Scotland, Wales and Northern Ireland, so use the relevant national government or council website. Do not assume an archived Household Support Fund application remains open in the 2026/27 financial year.

Numbers beginning with 0300 are charged at the same rate as calls to standard UK landline numbers and must count towards inclusive call allowances, according to Ofcom guidance referenced by GOV.UK. Your provider can confirm the exact charge under your tariff.

Avoid websites that place a premium-rate connection service between you and HMRC. The official UK helpline is 0300 200 3100, as listed by HMRC on GOV.UK, and you do not need to pay a third party simply to be transferred.

• Type GOV.UK directly into your browser rather than following an advert.
• Check that any online service uses a gov.uk address before entering personal details.
• Keep copies of forms, uploaded evidence and HMRC reference numbers.
• Tell HMRC promptly when an eligible change affects the claim.

Rates and rules can change: confirm current Child Benefit rates, tax thresholds and contact arrangements on GOV.UK before acting.
