If you had a baby in 2025, will your tax return be a refund or an amount due?
Most families confirm their tax draft without realizing they are leaving up to €2,200 on the table. We tell you exactly what deductions you have, which boxes they go in, and what errors cost money.
You've just had a baby, you're half-asleep, and suddenly you remember: tax season closes on June 30. Do you open the draft, see that you owe money, and confirm it without further thought? Stop. Breathe. And read this first.
When a child is born, your tax situation changes in a way that many traditional tax advisors won't explain without charging a separate consultation. At Babybelegal, we have been helping families for years to not lose a single euro they are entitled to.
How much money can you recover if you had a baby in 2025?
The short answer: up to €2,200 per child, combining state deductions. And that's not counting regional deductions, which in communities like Madrid or Catalonia can add several hundred more.
| Deduction | Maximum | Box | Automatic? |
|---|---|---|---|
| Maternity deduction | €1,200/child | 0611/0612 | Not always ✗ |
| Nursery voucher | €1,000 more | 0613 | No ✗ |
| Minimum for descendants | €2,400 exempt | 075–082 | Partial ◑ |
| Increase <3 years | +€2,800 | 075–082 | Not always ✗ |
| Working mother's aid | €1,200/year | 0611 | No ✗ |
If your baby was born in December 2025, you are entitled to the maternity deduction for the full month, even if it was only for a few days. Don't lose that month.
The maternity deduction: €1,200 that the Tax Agency won't remind you of
This is the great unknown. It allows you to deduct up to €1,200 per year for each child under 3 years old (€100 per month). You can receive it in two ways:
Option A: On the declaration
You apply it on your tax return and it reduces what you pay. No additional paperwork.
Up to €1,200/yearOption B: Monthly payment
You apply for Form 140 and receive €100/month. Then you deduct it on your tax return.
€100/month × 3 yearsWho is entitled?
- Mothers who are employed or self-employed and registered with social security
- Mothers who are receiving unemployment benefits at the time of birth
- Mothers who register with social security after birth, with at least 30 days contributed
The nursery voucher: €1,000 more that many families lose
If your baby attends an authorized nursery, you can add up to an additional €1,000. This raises the total maximum to €2,200 per child.
- The center must be authorized by the administration
- The nursery must have submitted Form 233 to the Tax Agency
- It is declared in box 0613
The minimum for descendants: reduces your taxable income
| Concept | Exempt base IRPF 2025 |
|---|---|
| 1st child | €2,400 |
| 2nd child | €2,700 |
| 3rd child | €4,000 |
| Increase under 3 years | +€2,800 |
If your baby was born in 2025, the €2,800 increase is automatically applied only if the baby is correctly listed in your tax draft. Check boxes 075-082.
Does maternity or paternity leave appear on the tax return?
The birth benefit is exempt from IRPF. You don't pay taxes. But the benefit is paid directly by the INSS, creating a second payer that affects the obligation to declare limit:
- With one payer: mandatory to declare if you earn more than €22,000
- With two or more payers: mandatory if you exceed €15,876 in total
The 5 most common mistakes when filing your tax return with a baby
-
Confirming the draft without checking boxes 611-613. The Tax Agency doesn't always apply the maternity deduction or the nursery voucher. We manage your full tax return.
-
Not including the baby if born late in the year. A baby born in November or December also generates deductions that year.
-
Not deducting the amount received from the €100/month aid. If you already received advance payments, you must subtract them. Otherwise, the Tax Agency will claim it from you.
-
Not reviewing regional deductions. Madrid and Catalonia have their own deductions that do not usually appear in the draft.
-
Choosing individual filing when joint filing would be better. With a baby, sometimes it pays to change the modality.

Frequently asked questions about tax returns with a baby
Can I apply the maternity deduction if I am self-employed?+
Yes. Since the 2022 reform, self-employed mothers registered with social security have the same rights. Up to €1,200 annually. If you have questions, our Consultancy for Self-Employed can guide you.
What happens if I didn't apply for the advance payment of €100/month?+
You don't lose it. You accumulate the entire deduction (up to €1,200) on your tax return. We help you with the management of this aid.
My baby was born in December 2025. Am I entitled to deductions?+
Yes. December counts as a full month. The minimum for descendants and the increase for children under 3 years old are applied in full. Do not confirm the draft without verifying that your baby is included.
Does maternity leave oblige me to declare if I didn't before?+
It can. The INSS benefit creates a second payer. If the INSS paid you more than €1,500 and your income exceeds €15,876, you are obliged to declare. If you have doubts, book a consultation with us.
Are there regional deductions in Madrid or Catalonia?+
Yes. Catalonia offers €150 per parent (€300 jointly). Madrid has nursery deductions depending on income level. Our Aid Study analyzes what you are entitled to. You can also contract the tax return for families.
Conclusion: don't confirm the draft without these checks
If you had a baby in 2025, this declaration is one of the most important in your tax life. Check that your child is in the descendants section, that boxes 611, 612 and 613 reflect what you are entitled to, and that you are not missing any regional deductions.
