The family disability tax deduction (deducción por discapacidad de familiar a cargo) is a tax incentive in Spain regulated under Article 81 bis of the Personal Income Tax Act (Law 35/2006). It allows working taxpayers (both employees and self-employed) to reduce their IRPF tax liability by €1,200 per year for each descendant (child, grandchild) or ascendant (parent, grandparent) with an accredited disability equal to or greater than 33%. For dependents with a severe disability of 65% or more, the tax credit is doubled to €2,400 per year through an additional €1,200 increment. Taxpayers can claim this credit on their annual Spanish tax return or receive it as a monthly advance payment of €100 or €200 by submitting Form 143 to the Tax Agency (AEAT). This credit is fully compatible with the large family tax deduction and the childcare allowance supplement.


🔍 Disability Degrees & Tax Credits 2026

The Tax Agency classifies family dependents based on parental relationship (descendant, ascendant, or non-separated spouse) and the official degree of disability certified by regional social services:

  • Disability between 33% and 64%: Grants a base tax credit of €1,200 per year per dependent. This equates to an advance payment of €100 per month.
  • Disability of 65% or more: Grants a total tax credit of €2,400 per year per dependent (including a €1,200 additional increment). This equates to an advance payment of €200 per month.
  • Disabled Spouse: If your spouse is not legally separated and has a disability degree of 33% or more, you can apply a €1,200 per year credit, provided they depend on you and do not exceed the income threshold.

📝 Worked examples

Example 1: Worker with a child having a 45% disability

Profile: An employee registered with Social Security has a minor child with an accredited disability degree of 45%.

Tax Credit Calculation
  • Accredited dependent: 1 descendant (child)
  • Disability degree: 45% (eligible for base tramo of €1,200/year)
  • Formula: €1,200.00 base credit
Annual Tax Credit: €1,200.00 (or €100.00 per month advance payment)

Example 2: Worker living with an 82-year-old mother having a 70% disability

Profile: An employee lives with their elderly mother, who has a certified disability of 70% and receives a minimum pension below the income limits.

Tax Credit Calculation
  • Accredited dependent: 1 ascendant (mother)
  • Disability degree: 70% (eligible for severe tramo of €2,400/year)
  • Formula: €1,200.00 base + €1,200.00 increment = €2,400.00 per year
Annual Tax Credit: €2,400.00 (or €200.00 per month advance payment)

Example 3: Contribuyente with a disabled child (40%) and disabled spouse (50%)

Profile: A worker claims a child with a 40% disability and their dependent, non-separated spouse who has a 50% disability.

Tax Credit Calculation
  • Accredited dependents: 1 descendant (€1,200/year) + 1 spouse (€1,200/year)
  • Disability degree of both: 33% - 64%
  • Formula: €1,200.00 + €1,200.00 = €2,400.00 per year
Annual Tax Credit: €2,400.00 (or €200.00 per month total advance payment)

⚠️ Common mistakes

  1. Overlooking the dependent’s annual income limit: The relative with the disability cannot earn more than €8,000 in taxable annual income. However, tax-exempt income (such as Spanish Social Security permanent absolute disability pensions) is excluded from this threshold. If the dependent earns more, AEAT will deny the credit and demand a repayment with interest.

  2. Filing Form 143 annually: Form 143 needs to be filed only once. Once approved, monthly payments continue automatically. Resubmitting the form every year creates duplicate records and halts processing.

  3. Failing to report the credit on your annual IRPF return: Even if you received the €100 monthly cash payments on time throughout the year, you must declare the credit and all advance payments on your annual tax return. Omitting this will trigger an automated review, forcing you to repay the entire €1,200.

  4. Both parents claiming 100% of the deduction on separate returns: If both parents work and file separate IRPF returns, the credit for the disabled child must be split 50/50 (€600 each) or transferred to one parent. Claiming 100% on both returns will trigger an immediate penalty.


🗂️ Special cases and regional rules

Single-Parent Families & Transfer of Rights

In a single-parent household, the sole parent claims the full 100% (€1,200). If both parents live together but only one works (and pays taxes), the working parent can claim the full 100% by having the other parent sign a transfer of rights form.

Assimilated Disabilities

Under Spanish tax rules, a person is legally assumed to have a disability of 33% or more if they receive a Social Security permanent total, absolute, or grand invalidity pension, or if their incapacity has been declared by a civil court.
