The disability child benefit supplement: who qualifies, what it pays and how long

A benefit many qualifying families never claim

Raising a child with a disability costs more than raising a child without one. It costs in therapy, in travel, in equipment, and above all in the working hours somebody in the family stops putting in. The Portuguese system's answer to that difference is called the bonificação do abono de família para crianças e jovens com deficiência, or simply the disability supplement.

It is a cash amount added to child benefit and paid to the same person, once a month, twelve times a year¹. It is for children and young people who need individual educational or therapeutic support suited to their disability and who attend, are resident in, or are in a position to attend a specialised rehabilitation establishment².

This article answers the three questions that decide everything: what it pays, who qualifies, and how long it lasts. The third is the one that misleads.

What it pays in 2026

The amount depends only on age. It does not depend on the family's income, on the number of siblings, or on the degree of incapacity.

The right-hand column is the same supplement increased by 50%, which is what the law provides where the child or young person belongs to a household with a single responsible adult¹. These are the figures published by the Instituto da Segurança Social in the 2 July 2026 edition of its practical guide.

It is worth noting that the 50% increase on the supplement is separate from, and cumulative with, the 50% increase child benefit itself already carries for single-parent families. In a single-parent household, both parts rise.

The rule almost nobody explains: the cut-off at 11

Search for the disability supplement and you will find dozens of pages carrying the table above and stating that it is paid to age 24. That information is incomplete, and the difference is large.

Decreto-Lei n.º 136/2019 put the third phase of the Prestação Social para a Inclusão into effect and redrew the map of disability benefits⁴. Since 1 October 2019:

• a new claim can only be filed for children up to 10;
• the supplement is paid until the month before the child turns 11;
• only those already receiving it on 30 September 2019 keep it to 24, as long as the conditions continue to be met¹.

That is why the 14-to-18 and 18-to-24 rows still exist in the table: they describe a cohort that is closing itself, not what a family claiming today will receive.

The good news is that the cut-off is not a loss. From 11 the applicable benefit becomes the Prestação Social para a Inclusão, whose base component for a claimant under 18 is €166.82 a month in 2026, plus 35% in a single-parent household, and to which a means-tested top-up may be added. That is more than double the €74.19 supplement. What cannot happen is receiving both: they are expressly non-cumulative¹.

It does not depend on the income bracket

This is the second idea to hold on to, and it is the one that stops qualifying families from ever claiming.

Child benefit works in brackets. The household's annual income is added up, divided by the number of entitled children plus one, and the result places the family in one of five brackets. In the fifth there is no benefit at all, and in the fourth the benefit is already zero for children over 72 months.

The disability supplement does not follow that logic. The Social Security practical guide is unambiguous when it deals with combinations: even where the family is in the 4th or 5th bracket and the young person receives no child benefit, the supplement can be paid¹. A comfortable household that has never received a cent of child benefit is still entitled to the €74.19 a month.

What does exist is an assets means test, which is different from an income test: the total movable assets of every member of the household, adding bank deposits, shares, savings certificates and other financial assets, must be below €128,911.20, that is 240 times the 2026 IAS¹⁵.

Who can claim and what has to be proved

Under the contributory scheme, the claim can be made by the father or mother, their spouse or partner, whoever lives with the child and cares for them, the legal representative, or the young person themselves if over 16¹. The claimant must have recorded earnings in twelve of the last fourteen months counted from the date of the claim, unless they are a pensioner.

There is also a non-contributory scheme, for those who pay into no social protection scheme and are in hardship, with its own thresholds indexed to the IAS¹.

Proof of disability is filed on form RP 5039 and assessed by Social Security's multidisciplinary medical and educational assessment teams, under the criteria of Portaria n.º 108/2021¹. It is not the multi-purpose medical incapacity certificate, which serves other purposes, notably tax ones. Where the disability is not permanent, the proof is requested by letter every year and must be renewed by 31 October; where it is permanent, there is no renewal.

The claim is made preferably on the Social Security Portal, under the Família menu, or at any service desk³. The deadline is six months from the month after the disability was verified: within the deadline it is paid from that month, outside it only from the month after the claim¹.

An example with numbers

A household with €12,000 of annual income and an 8-year-old child with a disability.

The child-benefit reference income is €12,000 divided by two, the number of entitled children plus one, which gives €6,000 and places the household in the 2nd bracket. Child benefit for a child over 72 months in that bracket is €75.13 a month. The supplement, up to 14, is €74.19. The family receives €149.32 a month, or €1,791.84 over a year.

If the household had a single responsible adult, both parts would rise by 50% and the total would become €223.99 a month.

If the annual income were €60,000, the reference income would be €30,000, above the limit of the 4th bracket, and child benefit would be zero. The supplement would still be paid: €74.19 a month.

Which other benefits it combines with

The supplement combines with child benefit, the prenatal allowance, the extra child benefit for second and third children under 36 months, the single-parent increase, study grants, the orphan pension, the survivor pension, the Rendimento Social de Inserção, the main informal carer allowance, the third-person care allowance, the special-education attendance allowance, the funeral allowance and the death grant¹.

It does not combine with the Prestação Social para a Inclusão, the dependency supplement, the Complemento Solidário para Idosos, invalidity and old-age pensions, the widowhood pension, unemployment benefit, sickness benefit, parental benefits or activity-cessation benefits¹.

Like every family benefit, the supplement is outside personal income tax and carries no Social Security deductions. The amount in the table is the amount that reaches the account.

What changes when the amounts are updated

The supplement's amounts are updated by portaria, as are child benefit and the IAS. The figures in this article are the 2026 ones, published in the practical guide of 2 July 2026. The age and combination rules come from the family benefits regime⁶ and from Decreto-Lei n.º 136/2019⁴, and do not change from year to year.
