How much do I deduct per child?+

How does IRS Jovem work in 2026?+
Up to age 35, in your first 10 years of income: 100% exempt in year 1, 75% in years 2–4, 50% in years 5–7 and 25% in years 8–10, up to 29 542,15 € a year (55 × IAS).
Is joint filing worth it?+
Usually when one partner earns much more, because income is split in two before the brackets apply. Try both: the Tax Authority's pre-assessment shows the better one.
