Tax and allowances

You can backdate a missed toeslag a whole year (the deadline just got longer)

Realised late you were entitled to zorgtoeslag, huurtoeslag or kindgebonden budget? You can still claim a full prior year retroactively. As of 2026 the deadline moved to 31 December of the following year, so for 2025 allowances you have until 31 Dec 2026, paid out in one lump. Exception: kinderopvangtoeslag must be claimed within 3 months of starting, so it cannot be deeply backdated. How: apply in Mijn toeslagen.
