Overwriting the home country IRS especially in Germany sounds so simple with the DTA.
If i look at the Germany-Malta DTA the article 4 would be:
"
2. Where by reason of the provisions of paragraph 1 an indi-vidual is a resident of both Contracting States, then his statusshall be determined as follows:
a) he shall be deemed to be a resident of the State in which hehas a permanent home available to him; if he has a perma-nent home available to him in both States, he shall bedeemed to be a resident of the State with which his personaland economic relations are closer (centre of vital interests);
b) if the State in which he has his centre of vital︀ interests cannotbe determined, or if he has not a permanent home availableto him in either︁ State, he shall be deemed to be a resident ofthe State in which he has︂ an habitual abode;
c) if he has an habitual abode in both States or in︃ neither ofthem, he shall be deemed to be a resident of the State ofwhich he︄ is a national;
d) if he is a national of both States or of neither︅ of them, thecompetent authorities of the Contracting States shall settlethe question by mutual agreement.
3. Where by reason of the provisions of paragraph 1 a compa-ny is a resident of︆ both Contracting States, then it shall bedeemed to be a resident of the State in︇ which its place of effec-tive management is situated.
"
If you rent/buy in the foreign︈ country and do not rent/own real estate in your home country, do not have a︉ key etc it should be clear that a) would be Malta. Economic interests with a︊ local company should also clearly be in Malta then.
Question is b/c if those are︋ only relevant if a) is not conclusive. Abitual abode can be a lot of things.︌ c) would favor Germany then if a) does not already overwrite b/c/d.
a) would even︍ overwrite a lot of other things which are known to be critical (center of vital︎ interests) unless you have a key to a German apartment.
