Everyone
who has a Place of Residence in Germany or has – as we say –
a Usual Place of Abode for more than six month, is taxable with his/her
world-wide income according to German Tax laws.
Within the
tax law, Place of Residence means to hold a residence. This does not
depend on a tenancy agreement or the fact whether you have registered
this place with the Registration Office. According to tax law, all evidence
of your non-temporary stay in Germany proofs your tax liability. A usual
place of abode is assumed if you stay for more than six months at a
time. If you do have the right to use the residence regularly, you automatically
fall under the tax law.
This period
of six months also applies, if the stay is interrupted. Also, the six
months period does not have to be within one calendar year. You are
recognized to have a usual place of abode in Germany if you arrive in
Germany - for example - in September, then spend the Christmas Holidays
in your home country and continue to live in Germany from January until
the end of April. In this case you are fully liable to pay taxes from
September until April.
