Portugal Child Benefit: Apply for Abono de Família or Request Reassessment

• Child benefit depends on residence, household resources, age and applicable education conditions.
• Child and applicant need NISS for the online request; a parent’s account is not the child’s identity record.
• The current ISS guide distinguishes income years for an existing award, a new 2026 request and reassessment.
• Child-benefit single-parent increase is 50% under the 2026 order; the prenatal increase is 35%.

Apply through the official child-benefit service, then use Social Security's named Abono de Família action. This is a monthly support for children and young people, not the IRS dependent deduction and not a universal payment to everyone with a child.

New request, automatic proposal or lower income?

Who can receive it?

The child must reside in Portugal or be treated as resident, meet the household income band and asset conditions, and satisfy the work/education rules. The current guide sets the movable-assets ceiling at €128,911.20 (240 times 2026 IAS). This is not the household salary threshold. A holiday-work exception exists for qualifying young people; do not assume all student employment preserves entitlement.

Use the NISS guide for a missing number and SSD access guide for login problems. Online applications require both the child and applicant to have NISS. Foreign-child evidence differs under EU/international coordination and other residence routes; check the current ISS list instead of treating a passport alone as universal proof.

How to request and track abono

1. 1
   Check the household first

   In the official portal use Perfil > Agregado e relações familiares to check the relevant record. IRS household data is not a substitute for checking this record.

2. 2
   Choose the named benefit service

   Follow Família > Desenvolvimento de crianças e jovens > Abono de Família para Crianças e Jovens > Consultar e pedir Abono de Família e Pré-Natal.

3. 3
   Select the correct request

   Under Pedir e consultar, choose Pedir novo abono de família, unless accepting an actual automatic proposal or seeking reassessment.

4. 4
   Submit the requested evidence

   Check child, applicant, household, income and representation details. For a counter request, consult RP5045 and the applicable GF54 household forms.

5. 5
   Save confirmation and check decisions

   Use Consultar under Ações for status and the separate payments area for payment dates. Answer evidence requests; submission is not approval.

What income year does Social Security use?

Reference income is the household's relevant annual income divided by the number of children entitled to child benefit plus one. For example, with two entitled children, the divisor is three—not the number of adults and children in the home. First establish the household and which income categories belong in the annual sum; the formula does not turn net monthly wages into an entitlement decision.

ISS Guide 4001 v4.81 distinguishes maintenance of existing awards using 2024 income, initial applications made in 2026 using 2025 income/IAS, and 2026 reassessment using current-year income/IAS. Do not use one table for all three. The reference-income calculation considers the defined household and count of entitled children, not simply take-home salary divided by every person living at the address.

2026 amounts and single-parent increase

For children up to 36 months, ordinary monthly base amounts are €190.98, €161.65, €132.07 and €88.43 for bands 1–4 respectively. Older-child bands differ. The 2026 order increases child benefit for a qualifying single-parent household by 50%; prenatal benefit uses 35%, not the same percentage. These base values are not an approval estimate; age, band and eligible supplements must be checked in the actual decision.

Income dropped: can I change the band?

The current guide allows reassessment when income decreases and at least 90 days have passed since the latest income proof or reassessment. Use Consultar e pedir reavaliação in the official benefit area. The guide says the decision becomes available from the 20th of the following month; this is not a guaranteed payment date. Keep evidence of changed income and correct household composition.

Deadline, missing payment and school proof

For a birth-related income replacement, check parental benefit; child benefit is a different award. For study records and transfers, follow the school enrolment guide. An eligible award may also be relevant to the social energy tariff, whose contract-holder and electricity/gas conditions must be checked separately.

The ISS deadline is six months from the first day of the month following the month entitlement begins, for example birth. Late claims generally start from the month after submission rather than recovering the whole earlier period. For ages 16–24, check the applicable study-level limit and July school-proof obligation. If payment stops, compare the award, school proof, residence evidence, household changes and payment record before submitting another application.
