Belastingadviseur gezocht voor IB-aangifte ivm inkomsten uit het buitenland (Finland)

Plaats: Wageningen

Gevraagde diensten: inkomstenbelasting, belastingadvies

Toelichting
I will place my question in English. Let me know if this works okay.

I will be receiving a grant from the university that I am enrolled in, this University is in Finland.
I do not know about the rules for income taxes related to grants, and would like some help understanding the rules for this.

My second question is that I will be obtaining a salary from my University in Finland for part of the Year 2021 and I will be living there part time in total six months but I do not know if I will be having to pay taxes for this income in the Netherlands (I can split the time in places, for example 3 months at a time).

Thank you for your time.

Best,
