Anyone else getting these questions from IB, if so do you know why? How long have you been receiving interest/dividend income? What type of investments are issuing you the interest/dividend income? In what year(s) did you make your trading profits? What financial products did you trade to earn these profits?
I assume you state dividends/interest as source of income and trading profits as source of funds. They want you to be more specific as part of their KYC procedure.
Did You try to add permissions lately? I believe is related to the fact that in order to trade certain asset classes You need an account with IB UK and restart all the process of verifications. That is a huge pita to an extent that when happened to me I decided to NOT open that account and give up the permissions .. seriously how the process is done is intimidating.
@Svalbards IB just seems to have stepped up his KYC requirements, have had accounts with various IB entities for over 10 years and never faced so much compliance hassle from them as over the last year (now IB Ireland) My account might be similar as your btw, enough to live off passive income, and much of the capital in it was made in financial markets
