Apply for tax exemptions for children over 18 years of age

Is your child over 18 years old? Find out here under what conditions you can receive the child tax allowance.

Detailed description

The child tax allowance is a tax-free allowance that deducts a child's subsistence level from taxable income. This reduces the amount of income tax payable. Unlike child benefit, it is not paid out directly, but rather taken into account to reduce the tax liability.



The child tax allowance normally ends when the child turns 18.



It may still apply to older children under certain conditions.



You are generally entitled to the child tax allowance if you are a parent or other legally equivalent person for whom a child is taken into account for tax purposes, i.e., biological parents or adoptive parents.



As foster parents or stepparents, you may be entitled to benefits if the child lives permanently in your household and a tax-related parent-child relationship is recognized.

    • There is no custody or care relationship with the biological parents.
  • The child is between 18 and 20 years old,
    • is not in any employment relationship and

Documents required

  • Provide the required information in the "Child Supplement" section of your income tax return.
  • This also applies if you have already provided the relevant information to the family benefits office.
  • Proof of the child's education, such as school or university certificate, apprenticeship contract or training certificate.
  • Proof of voluntary service

Please note

You will usually receive child benefit until the child's 25th birthday, provided the education or studies continue.



The tax office automatically checks whether child benefit or child tax allowance is more advantageous when processing the tax return.



You do not need to apply for the tax allowances separately. They are automatically taken into account during your income tax assessment.

Deadlines

If you do your taxes yourself, you generally have to submit your return by July 31st of the following year. If you use the services of a tax advisor, the deadline is usually extended to February 28th or 29th of the year after next.

Procedure

In Germany, you cannot apply for the child tax allowance separately. It is automatically taken into account as part of your tax assessment. The process typically works as follows:

  • You are applying for child benefit.
  • The relevant authority will automatically receive information about your children.
  • When you submit an income tax return, the responsible authority automatically checks whether child benefit or child tax allowance is more tax-efficient for you.
  • The amount of the tax-free allowance will be determined based on your information and marital status.
  • Your tax assessment will show whether the tax allowance was taken into account or whether child benefit was more advantageous.
