Child benefit in Spain: family support and IMV child supplement
Child benefit in Spain for low-income families usually comes through the IMV child supplement, not as a separate benefit. The supplement is added per child under 18 when the family already receives IMV.
Quick answer
- Child supplement: added to IMV for each child under 18 in the household.
- Amount 2026: 115, 80.50 or 57.50 euros per month per child, depending on the child’s age.
- Separate child benefit: available for families with limited income who do not receive IMV.
- Application: through the social security online portal with digital certificate or Cl@ve.

Check child benefit optionsHow child support routes work in Spain
- IMV child supplement: automatic addition when IMV is approved with children in the household.
- Standalone child benefit: for families above the IMV threshold but with limited income.
- Single parent supplement: additional amount for single-parent households.
- Disability supplement for children: additional amount if a child has a recognised disability.
- All routes require: proof of legal custody, child birth certificates and household registration.
What to do first
- Check whether your household qualifies for IMV. The child supplement is part of IMV.
- If you already receive IMV, check whether the child supplement is included in your payment.
- For the standalone benefit, check the income threshold for your household size.
- Gather birth certificates for all children and proof of legal custody.
Documents and evidence
- DNI/NIE/TIE or passport.
- SEPE/INSS decision, application receipt or expediente number.
- Work history report (vida laboral), contribution days, income documents and bank details.
Deadlines and risk
- Child supplement not included in your IMV payment: it may need to be requested separately.
- Child not registered at your address: INSS will not include them in the household calculation.
- Shared custody: only the custodial parent can claim. Dual claims are not allowed.
- Income above the standalone benefit threshold: the route changes to tax deductions.
- Missing documentation for a new child: supplement is delayed until documents are received.

The routes compared: CAPI, IMV supplement, and regional aid
Spain's child support for low-income households runs through Ley 19/2021 in two flavours. If the household qualifies for IMV, each child under 18 adds the ayuda para la infancia (CAPI) on top: 115 € /month per child under 3, 80.50 € from 3 to 6, and 57.50 € from 6 to 18 (2026 amounts). If the household is above the IMV income line but still modest, CAPI can be granted standalone — you apply through the same INSS portal and the INSS checks the CAPI-specific income ceiling for your household size. On top of either route, most autonomous communities run their own family aids — separate applications, separate rules, and they usually do not reduce CAPI.
How INSS counts your household (where most refusals are born)
The unit of calculation is the unidad de convivencia: the people registered at the same address (empadronamiento) and linked by marriage, partnership or kinship to the second degree. Practical consequences: a child not on your padrón does not count — fix the empadronamiento before applying; in shared custody only the parent the child is registered with can claim; a grandparent living with you is inside the unit and their income counts. INSS reads last year's income (AEAT data) but a current-year income drop can be argued with payslips and the cese/despido paperwork.
Applying and the clock: portal, documents, six months
Apply at the INSS/Seguridad Social electronic office (imv.seg-social.es route) with certificado digital or Cl@ve — or without ID via the unauthenticated form and later identity check. The pack: IDs of all adults, birth certificates, the empadronamiento colectivo (issued within the last 3 months), and custody papers where relevant. INSS has up to 6 months to resolve; silence is negative — but like all negative silence it just opens the appeal door. Payment, when granted, arrives monthly and is backdated to the first day of the month after filing.
Refused, or the supplement missing from your IMV? The 30-day lever
Two different problems, one tool. If IMV was granted but the child amounts are missing, that is a calculation error — file a solicitud de revisión citing the birth certificates already on file. If CAPI/IMV was refused, the route is reclamación previa within 30 working days of the notification (LRJS art. 71) — a written administrative appeal INSS must answer in 45 days before you can go to the social courts. Most winnable refusals are household-composition and income-year disputes: both are argued with documents, not opinions.
FAQ
My child was born this year — does the supplement start automatically?
No. Report the birth to INSS with the certificate; the amount is added from the month after you report, so report the same month.
Do regional aids reduce CAPI?
Generally no — CAPI is state-level. Check the regional aid's own rules for the reverse direction.
We are above the IMV line. Is standalone CAPI worth applying?
Yes if your income is modest — the CAPI ceiling is higher than the IMV one. The INSS simulator or a filed application settles it; refusal costs nothing.
Does CAPI affect taxes?
IMV/CAPI must be declared (recipients file IRPF) but the amounts are exempt up to the legal limit.
