Tax for money not generated in Hungary (Budapest)

Hi Budapest,
My wife and me will be relocated to Hungary at the beginning of June, as My wife has been offered a position in her international company office in Budapest.
We have savings generated from our jobs in Kurdistan Region and we want to transfer them to a bank account in Hungary.
Anybody knows if we have to pay any taxes on our savings once we deposit them in a bank account.. And if we have to pay how much it will be as percentage.
Thanks
