Kinderzuschlag: the child supplement

1. What Kinderzuschlag is, and how it differs from Kindergeld

Kinderzuschlag, often shortened to KiZ, is a supplement paid on top of Kindergeld. The two are administered by the same office, the Familienkasse, but they work on opposite principles and confusing them is the reason so many eligible families never apply.

Kindergeld is not income-tested: eligible families receive the same amount per eligible child. Kinderzuschlag is income-dependent and is aimed at households whose income and circumstances fit the statutory assessment.

It exists to fill a particular gap. A family whose income is very low receives basic support (Bürgergeld). A family whose income is comfortable needs nothing. Kinderzuschlag is for the band in between, where the parents work, earn too much for basic support, and still cannot cover the household from their wages.

2. How much is Kinderzuschlag?

The headline figure is a maximum, not a rate. Very few families receive the full amount, because the payment tapers as household income rises. That is the mechanism, not a defect: it means there is no cliff edge where a small pay rise costs you the whole benefit.

3. Who may qualify

There are conditions on the child, on your income and on your household as a whole. The income condition has both a floor and a ceiling, which is the part most people get wrong.

The floor exists because Kinderzuschlag is for working households: below a minimum income the correct benefit is basic support rather than this supplement. The ceiling is not a fixed number, because it depends on your rent and your household size, which is exactly why the official pre-check is more useful than any figure we could print.

4. Check before you apply: the KiZ-Lotse

The Familienkasse publishes a free pre-check called the KiZ-Lotse. You enter your household size, income and housing costs, and it indicates whether an application is likely to be worthwhile.

It is an indication, not a decision, and it does not commit you to anything. But it takes a few minutes and it answers the question that stops most families from applying at all.

5. What else Kinderzuschlag unlocks

This is the part families most often miss, and in some cases the additional entitlements are worth more than the cash supplement itself.

Receiving Kinderzuschlag opens access to education and participation benefits (Bildung und Teilhabe), and can support an exemption from childcare fees.

• School supplies allowance at the start of each school year
• Subsidised or free lunches at school and at Kita
• Contributions towards school trips and day excursions
• Support for sport, music and other organised activities
• Help with transport to school where applicable
• Possible exemption from Kita fees, applied for through the local Jugendamt

6. How to apply

The application goes to the same Familienkasse that handles your Kindergeld, and it is free. It asks for considerably more evidence than a Kindergeld claim, because it is income-tested.

1. 1

   Run the pre-check first

   It takes a few minutes and tells you whether the paperwork is likely to be worth assembling.

2. 2

   Gather income and housing evidence

   Recent payslips for both parents, your rental contract, and evidence of heating and service charges. Self-employed parents need their profit figures.

3. 3

   Submit the application to the Familienkasse

   It can be filed online. Apply in the month you want payment to start: Kinderzuschlag is not backdated in the way some benefits are.

4. 4

   Consider Wohngeld at the same time

   The two are assessed together in the underlying calculation, and applying for housing benefit alongside can change the outcome. The Familienkasse will often flag this.

5. 5

   Diarise the reapplication

   Approval runs for six months. Put the end date in your calendar the day the decision arrives, because nobody will remind you and a gap is not backdated.
