Complemento de Ayuda para la Infancia (CAPI)

The Child Welfare Supplement (Complemento de Ayuda para la Infancia, CAPI) is a monthly Spanish Social Security benefit paid in addition to (or independently of) the Minimum Living Income (Ingreso Mínimo Vital, IMV). It was created to provide a structural, predictable cash transfer for every dependent child living in a low-income household, and it represents one of the most significant pieces of social policy in Spain since the post-2008 reforms. The supplement is paid by the Instituto Nacional de la Seguridad Social (INSS), the same body that administers the IMV.

The legal foundations of the CAPI are clear. The base statute is Ley 19/2021 de 20 de diciembre, por la que se establece el ingreso mínimo vital, which transformed the original Real Decreto-Ley 20/2020 into a permanent right and embedded the new complemento de ayuda para la infancia within the IMV architecture. Real Decreto-Ley 20/2022 de 27 de diciembre, de medidas de respuesta a las consecuencias económicas y sociales de la guerra de Ucrania y de apoyo a la reconstrucción, formally introduced the CAPI as a stand-alone, payable supplement, and Real Decreto 222/2024 de 27 de febrero updated thresholds, indexing rules, and administrative procedures so the supplement could be modulated by vulnerability bands rather than treated as a single flat top-up.

The purpose of the CAPI is twofold. First, it is intended to reduce child poverty, which has long sat above the EU-27 average in Spain (around 28% of children at risk of poverty or social exclusion in 2022 according to INE/AROPE figures). Second, it is designed to be universal in coverage among low-income households: the supplement is paid not only to families already receiving IMV, but also to families slightly above the IMV income line who still face material deprivation. This double scope — IMV-linked and CAPI-only — is the operational innovation introduced by article 11bis of Ley 19/2021 and developed by Real Decreto 222/2024.

In policy terms, the CAPI represents Spain's first move toward what economists describe as a quasi-universal child allowance with income-modulated amounts. It does not replace the older prestación por hijo a cargo (which has been phased out for new claimants since 2020) nor does it interact with regional minimum incomes (rentas mínimas autonómicas), which continue alongside it. The CAPI is therefore a national, non-contributory benefit financed from the Presupuestos Generales del Estado and managed centrally by the INSS, with regional Social Security delegations and oficinas de atención e información de la Seguridad Social (CAISS) acting as front desks.

Eligibility for the CAPI is determined by two filters: a family composition filter (at least one dependent minor child) and an income filter (household income below the relevant threshold). Both must be met simultaneously, and both are verified annually against the previous fiscal year's declaración de la renta (IRPF).

Family composition. The applicant household must include at least one dependent child under 18, registered together with the applicant on the libro de familia or equivalent. The age limit extends to 23 years if the dependent has a recognised disability of 33% or more (certified by the IMSERSO or the autonomous community). The child must be legally resident in Spain and registered (empadronado) at the same address as the applicant for at least the six months preceding the application — the same rule that governs IMV's unidad de convivencia.

Income thresholds. Eligibility is graduated by reference to the official umbral de pobreza (poverty line) published annually by INE. For 2025, a household qualifies for CAPI when total annual income falls below 200% of the umbral de pobreza, which works out to approximately:

• Single adult + 1 child: ~€13,200/year
• Single adult + 2 children: ~€15,840/year
• Couple + 1 child: ~€15,840/year
• Couple + 2 children: ~€18,480/year
• Couple + 3 children: ~€21,120/year

Vulnerability modulation. Real Decreto 222/2024 introduced three vulnerability bands that determine which CAPI amount applies (see next section): severe poverty (household income below €300/month per adult equivalent), moderate poverty, and low income (between 150% and 200% of the umbral de pobreza). Higher CAPI rates flow to severe-poverty households; the lowest rates are paid to households just under the 200% line.

IMV recipients. Families who already receive IMV are automatically enrolled in CAPI for each dependent minor in the household — no separate application is required. The supplement is paid in the same month as the IMV and shown on the INSS monthly statement.

Non-IMV low-income families. Households whose income is above the IMV threshold but below 200% of the umbral de pobreza must file a separate CAPI-only application using Anexo II of the relevant order. This is the principal source of the so-called coverage gap — an estimated 580,000 children in 2024 were potentially eligible but had not applied (see Section 7).

Other technical requirements include: legal residence in Spain (residencia legal y efectiva) for at least one year before the application, prior application for any benefit to which the household is entitled (subsidio por desempleo, pensión no contributiva, etc.), and no permanent institutionalisation of the dependent child in publicly funded care.

The CAPI amount depends on two variables: the age of each dependent child and the vulnerability band of the household. The age-banded base amounts are fixed by Real Decreto 222/2024 and revalued annually together with the IPREM and the IMV.

Base amounts 2025 (per child, per month):

• Children aged 0 to 3 years: €115.00/month per child
• Children aged 3 to 6 years: €80.50/month per child
• Children aged 6 to 18 years: €57.50/month per child

A household with three children aged 2, 5, and 10 therefore receives a base CAPI of €115 + €80.50 + €57.50 = €253/month, which is €3,036/year. The amounts are paid in 12 monthly instalments, not 14 — the CAPI does not carry the seasonal pagas extras of contributory pensions.

Vulnerability modulation. The figures above are the standard amounts paid to households in the moderate poverty band. The Real Decreto 222/2024 vulnerability schedule applies the following modifiers:

• Severe poverty (per-adult income below €300/month): standard amount + 22% supplement (the same coefficient used for monoparentalidad)
• Moderate poverty: standard amount (rates listed above)
• Low income (150% – 200% of the umbral de pobreza): standard amount × 0.75 (reduced rate)

A child aged 0 – 3 in a severe-poverty household therefore generates €140.30/month; the same child in a low-income household receives €86.25/month. The modulation is recalculated each year against the household's IRPF declaration; INSS performs an automatic recalculation in the second quarter following the close of the fiscal year.

Monoparentalidad complement. If the household is a single-parent family (familia monoparental) recognised by the autonomous community or by the registry of the Ministerio de Derechos Sociales, the CAPI base amount is further increased by 22%. This complement is cumulative with the severe-poverty modifier but capped at the maximum scale published by INSS.

Multi-child cap. Real Decreto 222/2024 does not impose a hard cap on the number of children per household, but the combined CAPI + IMV is limited to 220% of the IMV base amount for the household composition. In practice this only binds for households with five or more minors.

Worked example. A couple with two children (ages 4 and 9) in moderate poverty: CAPI = €80.50 + €57.50 = €138/month. If the same family is on IMV, the total monthly payment is the IMV base for couple + 2 minors (~€1,027) plus CAPI of €138 = ~€1,165/month, paid by INSS in a single transfer.

All amounts are exempt from IRPF under article 7.y of the LIRPF, so the gross amount equals the net amount received by the family.

The CAPI application route depends on whether the household already receives the IMV. IMV recipients do not file a CAPI application — the supplement is added automatically by the INSS when at least one dependent minor appears on the IMV file. Non-IMV households must file a separate CAPI-only application using Anexo II of Orden ISM/835/2023.

Channel 1 — Online via the Seguridad Social portal. Open sede.seg-social.gob.es, navigate to Familia → Complemento de ayuda para la infancia, and authenticate with one of: (a) Cl@ve permanente, (b) certificado digital (FNMT or similar), or (c) DNIe with a compatible card reader. The online procedure has the advantage of automatic data prefill from INSS records and immediate file numbering.

Channel 2 — Paper or appointment at a CAISS. Print Anexo II from the Seguridad Social website, complete it by hand or by computer, and submit it at any oficina de atención e información de la Seguridad Social (CAISS) after booking an appointment via citaprevia.seg-social.gob.es or the phone line 915 412 530. Some autonomous communities accept submissions at municipal social services offices that have a cooperation agreement with INSS.

Channel 3 — Postal submission. Anexo II plus the documentation listed below can be sent by registered post (correo certificado administrativo) to the address of the INSS Dirección Provincial corresponding to the applicant's municipality of empadronamiento.

Required documentation:

• DNI/NIE of the applicant and of each adult in the household unit
• Libro de familia or certificado de nacimiento of each dependent child
• Certificado de empadronamiento colectivo issued by the municipality, less than three months old, listing all household members
• Declaración de la renta (IRPF) of the last completed fiscal year for each adult, or certificado de imputaciones from AEAT if not required to file
• Certificado de prestaciones del SEPE if any household member is unemployed
• Certificado de discapacidad (if applicable) for dependents aged 18 – 23
• IBAN of a Spanish bank account in the applicant's name
• Optional but recommended: certificado de monoparentalidad if applicable

Processing time. INSS has a legal maximum of 180 days (six months) to resolve a CAPI-only application under article 19 of Ley 19/2021. The average processing time in 2024 was 86 days according to the INSS annual report. If 180 days elapse without resolution, the application is deemed denegada por silencio administrativo, but in practice INSS issues retroactive payments once the file is resolved.

Payment. Once approved, CAPI is paid monthly into the IBAN provided, with the first payment retroactive to the month of application. The right is recognised for 12 months and is recalculated each January based on the IRPF of the previous year.

Appeals. Denial decisions can be appealed by reclamación administrativa previa (within 30 days of notification) and, if denied again, by demanda ante el Juzgado de lo Social (within 30 days of the administrative resolution). Legal aid is available through the Servicio de Orientación Jurídica at the relevant Colegio de Abogados.

For step-by-step walk-throughs in plain language, document checklists by household profile, and a free calculator that estimates the exact CAPI amount you should receive each month, see Buronia's Spanish CAPI guide, which integrates the IRPF logic and the vulnerability bands so the application is filled out correctly the first time.

The Spanish CAPI is one of several European cash transfers for children, but it differs from its peers in two important ways: it is means-tested (most northern European child allowances are universal), and it is vertically integrated with a minimum income scheme (the IMV) rather than administered as a stand-alone benefit. Understanding the comparative landscape helps Spanish families set expectations and helps EU citizens moving to Spain understand what to apply for.

Germany — Kindergeld. The German Kindergeld is the gold-standard universal child allowance: €255/month per child from 2025, paid regardless of household income to every legal resident with dependent children up to age 18 (extended to 25 if in training). The €255 figure dwarfs the Spanish CAPI base of €57.50–€115. However, Kindergeld is not modulated by poverty band — a low-income German family also receives €255 per child, but does not benefit from the kind of vertical integration with social-assistance benefits that the Spanish IMV+CAPI combination provides.

France — Allocations familiales. France pays allocations familiales only from the second child onwards: €145.74/month for 2 children, with progressive amounts up to €332.34 for 3+ children, means-tested since 2015. There is no monthly allowance for first-only children in France; instead, low-income families rely on the complément familial (€194.78/month for 3+ children below an income ceiling). The French system is more generous than the Spanish for large families with three or more children, but less generous for single-child households below the poverty line.

Italy — Assegno unico universale (AUU). Introduced in March 2022, the Italian AUU pays €57.50 – €189.90/month per child depending on the ISEE income indicator and family composition. The CAPI architecture (vulnerability bands with stepped amounts) is closer to the Italian AUU than to the German Kindergeld, but the AUU is more generous at the lower end of the income scale because the maximum amount applies to families with ISEE below €17,090/year.

Austria — Familienbeihilfe. Austria pays €126 – €185/month per child depending on age (rising with age, the opposite of the Spanish CAPI logic). The Austrian allowance is universal, with an additional Mehrkindzuschlag for large families and a 13. Familienbeihilfe bonus in September to cover school start-up costs.

Portugal — Abono de família. The Portuguese abono de família para crianças e jovens is means-tested and pays €51.20 – €157.42/month per child across five income brackets. The Portuguese system is structurally similar to the Spanish CAPI (means-tested, age-banded, paid by Social Security) but uses five income tiers rather than three vulnerability bands.

United Kingdom — Child Benefit. The UK pays £25.60/week (~€121/month) for the eldest child and £16.95/week (~€80/month) for each additional child. Child Benefit is universal but subject to the High Income Child Benefit Charge for incomes above £60,000.

Comparative position of Spain. By absolute amount, the Spanish CAPI is at the lower end of EU comparators — a Spanish family with two children under 6 receives ~€195/month from CAPI alone, whereas a German family receives €510 from Kindergeld. However, when CAPI is combined with the IMV base amount for couple + 2 minors (~€1,027/month), the total cash transfer for a Spanish low-income family is competitive with northern European systems. The trade-off is universality: a middle-income Spanish family receives no CAPI, whereas a middle-income German family receives the same Kindergeld as a poor family.

The CAPI sits inside a broader ecosystem of Spanish family-support benefits. Understanding what stacks with it (and what does not) is essential for any household trying to maximise net cash income and material support.

Ingreso Mínimo Vital (IMV). The flagship benefit. IMV pays a base amount that ranges from €604/month (single adult) to ~€1,208/month (large household, 4+ adults/minors). CAPI is added on top automatically for every dependent minor in an IMV household, so the combined IMV+CAPI is the standard package for low-income families. The asset and income thresholds are stricter for IMV than for CAPI alone, which is why CAPI has a larger eligibility pool than IMV.

Prestación por hijo a cargo (legacy). The old prestación familiar por hijo a cargo, which paid €341/year per non-disabled child below the income threshold, has been closed to new applicants since 1 June 2020. Households that were receiving it on that date continue to do so, but new low-income families with children must apply for CAPI instead. Households with a child with a disability of 33% or more still have access to the prestación por hijo con discapacidad, which pays €115 – €493/month depending on the degree of disability.

Bono social eléctrico. A discount of 25% (or 65% for consumidor vulnerable severo) on the electricity bill, automatically extended to IMV+CAPI households on application. The bono social is processed by the electricity retailer (comercializadora de referencia) and requires the household to be on the PVPC tariff and to submit the certificado IMV issued by INSS.

Bono social térmico. A separate annual cash transfer (€25 – €375 depending on climate zone) for heating expenses, paid to bono social eléctrico recipients each winter without a separate application.

Becas comedor escolar. Subsidies for school lunches managed by autonomous communities and municipalities. Most regions (Madrid, Cataluña, Valencia, Andalucía) prioritise IMV+CAPI households in their scoring, and several (e.g. País Vasco) automatically grant the full subsidy without further means-testing. Application is via the regional consejería de educación at the start of each school year.

Ayudas a libros de texto. Regional grants of €100 – €350/year for textbooks and school supplies, granted on a sliding scale that uses the IRPF declaration. CAPI eligibility is generally sufficient to qualify for the maximum grant in most regions.

Bono Alquiler Joven. €250/month for under-35s renting their habitual residence, compatible with CAPI but requiring a separate application to the autonomous community. Applicants must have a stable income source (which can include IMV+CAPI).

Rentas mínimas autonómicas. Regional minimum-income schemes (Renta Garantizada de Ciudadanía in Cataluña, RGI in País Vasco, Renta Mínima de Inserción in Madrid). These coexist with IMV+CAPI and are generally compensatory — when a household receives IMV+CAPI, the regional benefit is reduced or topped up depending on the regional rules.

Permiso de paternidad y maternidad / prestaciones por nacimiento. Contributory benefits paid by Social Security during the 16 weeks of parental leave. These do not stack with CAPI eligibility checks because they are excluded from the IRPF income computation under Real Decreto 222/2024.

Tax deductions. The IRPF offers a deducción por maternidad of up to €1,200/year for working mothers with children under 3, and a deducción por familia numerosa of €1,200 – €2,400/year for large families. These are fully compatible with CAPI and are claimed on the annual tax return.

The CAPI is, in administrative terms, one of the largest cash-transfer programmes in Spain by number of beneficiaries, although still a long way from universal coverage of eligible children. The most recent official statistics (INSS annual report 2024, AIReF 2024 evaluation report, INE) paint a picture of rapid growth and persistent under-take-up.

Beneficiaries 2024. Approximately 870,000 children received CAPI at least once during 2024, distributed across ~340,000 households. The average CAPI payment per household was €145/month, equivalent to roughly two children per CAPI household. By comparison, in 2023 the figure was 720,000 children in 285,000 households, and in 2022 (the first full year of CAPI as a stand-alone supplement) only 410,000 children — a growth rate of ~110% in two years.

Vulnerability distribution. According to AIReF's 2024 evaluation, 38% of CAPI households fall into the severe poverty band (per-adult income below €300/month), 47% into moderate poverty, and 15% into low income. The severe-poverty share has fallen 6 percentage points since 2022 as the supplement reaches households at the margin of eligibility.

Geographic distribution. The CAPI is highly concentrated in southern Spain: Andalucía (24%), Comunitat Valenciana (12%), Madrid (11%), Cataluña (10%), and Canarias (8%) account for roughly two-thirds of all beneficiaries. By contrast, País Vasco and Navarra — which manage their own integrated minimum-income schemes — represent less than 3% of national CAPI beneficiaries combined.

Coverage gap. The most worrying statistic concerns the children who are eligible but not receiving CAPI. AIReF estimates that ~580,000 additional children would be eligible for CAPI in 2024 if their families applied. The gap is concentrated in non-IMV households who are eligible only for CAPI-only and who often do not realise the supplement is available without IMV. This is the principal failure of the CAPI design and the focus of the 2025 INSS take-up campaign (see below).

Budget. CAPI expenditure was €590 million in 2024, up from €230 million in 2022. The 2026 Presupuestos Generales del Estado allocates €780 million to CAPI, anticipating a continued rise in beneficiaries as awareness grows.

2025 take-up campaign. INSS launched in February 2025 a national awareness campaign — "¿Tienes hijos? Puede que tengas derecho." — that combines TV/digital ads, postal campaigns to households flagged by AEAT income data, and partnerships with the network of municipal social services (servicios sociales de base). The target is to close 40% of the coverage gap (~230,000 additional children) by year-end 2025.

Integration with regional schemes. The 2024 – 2030 strategy of the Ministerio de Inclusión, Seguridad Social y Migraciones includes a plan to integrate the CAPI vertically with regional renta complementaria schemes, so that families do not need to apply separately for national and regional benefits. Pilot agreements have been signed with the Generalitat Valenciana (2024) and the Junta de Andalucía (2025); a national rollout is anticipated by 2027.

Outlook to 2030. The Plan Estratégico Nacional para la Reducción de la Pobreza Infantil 2024 – 2030 sets a target of 50% reduction in child AROPE (at-risk-of-poverty-and-social-exclusion) from 2022 levels by 2030. Reaching that target requires either an increase of CAPI base amounts (politically debated, fiscally significant) or a substantial closure of the coverage gap (administratively feasible). Most analyses (e.g. ESADE-Fundación La Caixa, 2024) conclude that the gap-closure route is the more impactful and cheaper of the two, and INSS strategy reflects that conclusion.

For families wondering whether they are part of the 580,000-child coverage gap, the simplest test is the IRPF threshold: if total household income for the previous fiscal year is below approximately €18,000 (couple + 2 children) or €15,840 (single parent + 2 children), it is worth running a CAPI simulation and filing Anexo II. The downside of applying is zero (no penalty for denial), and the upside is up to €253/month per household — €3,036/year — for the years the child remains under 18.
