Members remuneration and expense
allowance
Members' staff
No Member can cope alone with the duties imposed upon them by a parliamentary mandate. It is impossible to manage without the assistance of qualified staff. Members are therefore able to spend about € 13,660 a month on employing people to help them. However, Members do not receive this sum themselves. Rather, the Administration of the German Bundestag pays it directly to the staff appointed by Members. Staff who are related to Members by blood or marriage are excepted from these provisions. Any Member who employed relatives would have to pay their salaries himself or herself.
