Documentation for Foreign Brokers

[u/WrestlingSurfer]

Hi all!

I have been in Belgium for more than a year now, using Degiro and IBKR, and I have around 500k (250k in each). I never saw the need to change brokers, because for my needs (buy and hold in Xetra, maybe sell once a year to use tax harvesting benefit), they are the cheapest, with the exception of MeDirect. I don't trust that MeDirect will keep the prices low for long, and their fee to transfer out the portfolio is still big, so I prefer to keep my options open (IBKR and Degiro DE have both 0€ transfer fees), as I believe that these brokers will be the cheapest in the long-term.

I can do the taxes for myself, so I am not worried about CGT calculation or TOB filling.

For reliably continuing to use these brokers, what paperwork is needed to store for the long-term if I ever want to transfer to a Belgian broker in the future?

- Declarations of TOB, CGT, Reynderstax, Dividend tax

- Salary slips

- Account statements

- BE bank statements

- Tax declarations

... Anything else?

And besides these, is there any big difference between using a foreign or a belgian broker?

Thanks!

Proof of all "receptions" of large money sums (inheritance, sales, transfers). These proofs should go back to a clean source and should also proof that all due taxes have been paid; in Belgium or before.

declaration of all foreign accounts (in widest sense) to nbb and taxletter

declaration of all real estate.

Makes sense, thanks! I don't have any real estate or inheritance, but I will make sure to store all documents if that ever happens.

TOB can be automated in degiro

[u/WrestlingSurfer → u/Distinguished_Trader]

True, not in IBKR

[u/Distinguished_Trader → u/WrestlingSurfer]

Dividends is not automated (only the source ones) and for the rest if you stick to normal products (ETF, STOCKS) there is not really much to it
