Bitcoin Core is open-source software run by you. Since you control the funds, I would expect that they reside in the same country as you. I am neither a lawyer nor a tax consultant, but you should probably talk to one of those if you being in control of your funds is insufficient to resolve your problem.
I am not a tax advisor, and you probably want to seek professional advice in your jurisdiction instead.
That said, it would seem very strange to me that merely transferring funds within wallets/accounts of your own would be considered a trade for tax purposes. I would expect that some conversion to another asset type is needed for that.
