I hold a double nationality: Swedish and Ukrainian.
Currently, I am employed and live in Sweden. Since I'm not a tax resident of Ukraine, I do not declare any taxes there.
Next year I may take unpaid leave from my current job to do some contracting work in Ukraine as a self-employed person (UK: приватний пидприемець).
It is very unclear for me whether I should declare that income in Sweden due to two reasons:
- Sweden and Ukraine have double taxation agreement] (SE: dubbelbeskattningsavtal; UA: Закон N 135/96-ВР)
- Different nature of income (self-employed vs employed)
Also, what does leaving Sweden, say in February for more than six months means when it comes to paying an income tax in Sweden for that year?
