Kinderzuschlag

Kinderzuschlag (child supplement, often abbreviated KiZ) is an extra monthly payment on top of Kindergeld, aimed at working families whose income covers their own needs but not quite their children’s.

Quick Summary

Kinderzuschlag pays up to €297/month per child (2026), for families who already receive Kindergeld, earn enough to support themselves but not their children’s needs, and don’t already qualify for Bürgergeld.

Who Needs This

• You already receive Kindergeld for your children
• Your income is modest but you’re working, and you’d otherwise be just short of covering your children’s costs
• You want to avoid needing to claim Bürgergeld (basic income support) if this top-up is enough to close the gap

Eligibility

• Your child must be under 25, unmarried, and living in your household.
• You must already be receiving Kindergeld for that child.
• Your own income must clear a minimum threshold — currently €900/month (couples) or €600/month (single parents) — since Kinderzuschlag tops up working families, not those with no income.
• Your income must also stay below an upper limit, which depends on household size and housing costs.
• Foreign nationals: if you’re an EU citizen, or a non-EU citizen with a valid residence and work permit, you have the same right to apply as German citizens.

Step-By-Step: Applying

1. Confirm you’re already receiving Kindergeld for the child (Kinderzuschlag cannot be claimed without it).
2. Use the Familienkasse’s online Kinderzuschlag calculator or ask an advisor to estimate whether your income falls in the qualifying range.
3. Gather proof of income for you (and your partner, if applicable) and your housing costs.
4. Submit the application online via the Familienkasse portal, or by mail/in person at a Familienkasse branch.
5. Expect processing to take around 4–8 weeks; providing complete documentation upfront speeds this up.
6. Note that approval is granted for 6 months at a time — mark your calendar to reapply before it lapses, since it does not renew automatically.

Bildung und Teilhabe comes with this

Households receiving Kinderzuschlag automatically become eligible for the Bildung und Teilhabe package too — covering school trips, supplies, and leisure activities for your children.

Common Documents

• Proof you’re receiving Kindergeld
• Recent payslips or proof of income for both parents (if applicable)
• Proof of housing costs (rental contract, utility costs)
• Bank account details

Common Mistakes

• Applying without already having an active Kindergeld claim
• Not reapplying before the 6-month approval period lapses
• Assuming eligibility is only for very low incomes — it specifically targets working families just above the threshold for other support
• Missing that Kinderzuschlag also unlocks Bildung und Teilhabe eligibility

Important Note

Income thresholds and the maximum amount change periodically. Use the Familienkasse’s official calculator or ask them directly to confirm your specific eligibility before assuming you qualify.
