You may not know this, but families with children under 18 can access the Child Support Supplement (CAPI) even if their income exceeds the limits of the Minimum Living Income (IMV).
The benefit, in effect since February 2022, goes unnoticed by many households that would actually qualify.
The Child Support Supplement is part of the Minimum Living Income, but it operates under its own rules.
Although it is applied for through the IMV form, it has broader income and asset thresholds, meaning that middle-income families can benefit without receiving the IMV itself.
The benefit was created with the reform of the IMV Law, which took effect on February 1, 2022, as a specific support measure for children.
How much is the CAPI benefit?
The amounts in effect in 2026 are fixed for each dependent child:
- Children under 3 years old: €115/month
- Ages 3 to 6: €80.50/month
- Ages 6 to 18: €57.50/month
What differs is the income threshold based on the household unit and its members. Households with at least one minor who meet the general IMV requirements are eligible for the CAPI, except for the income, asset, and asset test limits, which are more lenient in the case of the supplement.
A family consisting of two adults and two children can receive the CAPI on its own (without the IMV) with monthly incomes of up to €4,181.52. For a single-parent family with one child, the ceiling is €2,861.04 per month.
Regarding net assets (excluding the primary residence), the limits also vary depending on household composition: from €55,460 for an adult with one child to €102,997 for larger households.
How to apply for the CAPI
The application is submitted through the IMV website (imv.seg-social.es). Before submitting it, Social Security provides users with a simulator to check whether they are eligible for the benefit.
