@maska You will definitely need to discuss with DeGiro on your migration regarding the administrative Aspects of your trading accounts. Regarding taxation, my expectation is that given that Spain might lose its right to taxation on your capital gains, they might impose a tax on the transfer of your tax residence on these assets. Of course you could claim the value of the asset base increase on the country you move to. But looks like you’ll need to consult with a Spanish tax expert on migration as well as one in the country you move to. But definitely you’ll need to update DeGiro res your move, perhaps they can transfer your holdings to a broker of your choice in the country you move to. Hope this helps.
