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 vital interests cannotbe determined, or if he has not a permanent home availableto him in either State, he shall be deemed to be a resident ofthe State in which he has an habitual abode;
c) if he has an habitual abode in both States or in neither ofthem, he shall be deemed to be a resident of the State ofwhich he is a national;
d) if he is a national of both States or of neither 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 of both Contracting States, then it shall bedeemed to be a resident of the State in which its place of effec-tive management is situated.
"
If you rent/buy in the foreign country and do not rent/own real estate in your home country, do not have a key etc it should be clear that a) would be Malta. Economic interests with a local company should also clearly be in Malta then.
Question is b/c if those are 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 even overwrite a lot of other things which are known to be critical (center of vital interests) unless you have a key to a German apartment.
