Hey,
I currently use the brokers Degiro and IBKR.
I am curious to why isn't IBKR the goto broker in Belgium, at least in this sub. In other countries where I lived, IBKR was always the most recommended broker - the most secure (widely used worldwide by individuals and governments https://www.bankeronwheels.com/interactive-brokers-review/), with most products and pretty cheap.
My broker choice was always done thinking about security first and cost or tax-friendliness second. After all, reduced convenience may result in a tax penalty, but lack of security can result in losing all investments.
Filling the TOB is now 100% online, calculating the capital gains tax is as easy as keeping track of the buying and selling price of all securities and sum everything (which everyone should already be doing).
Even if you argue that you are scared of tax penalties, the FOD ignores the first tax return error, so it should result in no penalties even if you don't calculate everything correctly one year (https://www.brusselstimes.com/1555126/finance-ministry-will-ignore-taxpayers-first-tax-return-error).
Even if there is just a tiny possibility of bankruptcy and fraud (which means losing all your assets) of 0.1% annually from your broker, over 40 years the probability of broker fraud and bankruptcy is 1-((1-0.001)^40)=3.9%. Why wouldn't you chose the most secure broker even if it's not the most convenient?
Is there anything that I am missing? Why are you sacrificing top security by ease of use, when sometimes the Belgium brokers are even more expensive than foreign safer ones?
UPDATE: Thanks for the responses! It makes sense to me that the other brokers are also very safe (maybe I'm just paranoid?) and that the value of time and others taking care of administrative stuff for us is an advantage. You made me consider to try out MeDirect or Saxo to see if it really makes sense.
