If your financial situation or living circumstances have improved or changed, this may also lead to a reduction in housing benefit. You are obliged to inform the housing benefit authority immediately of any changes that could lead to a reduction in your housing benefit. In order to prevent or uncover unlawful claims for housing benefit, the housing benefit authority regularly checks the household members by comparing their data.

In order to avoid or uncover unlawful claiming of housing benefit, the housing benefit authority may regularly check the household members by comparing data - also in automated form - in particular with the pension insurance data office.

For example, the following may be compared

• whether citizen's allowance (formerly unemployment benefit II) is being paid while the housing benefit is being received,
• whether there is employment subject to compulsory insurance or marginal employment,
• or the amount of investment income for which an exemption order has been issued.

It is also possible to compare registration addresses, housing status and the time of re-registrations with the registration office. It is also possible to call up accounts at the Federal Central Tax Office. Suspected cases of fraud are always reported to the public prosecutor's office.

Through these checks, the housing benefit authority can determine, for example

• whether housing benefit is being received more than once,
• whether transfer payments leading to exclusion from housing benefit are being received at the same time,
• whether correct information in the housing benefit application
  • on income from gainful employment,
  • income from one or more pensions,
  • income from capital gains (interest or dividends),
• whether the payment of unemployment benefit was discontinued in the case of original unemployment (e.g. due to taking up new employment) and
• whether the original home for which housing benefit was paid is still actually being used.

The review is permitted up to ten years after notification of the associated housing benefit approval.
