IBKR operates as an international broker, so unless an existing client relocates to a country where we are prohibited, by regulation, from doing business, there should be no problems with continuing your relationship if you move.
Some points to consider:
- The client's country of legal residency is a key factor in determining the IBKR entity with which their account is maintained. As a result, the possibility exists that the account will need to be transitioned to a new IBKR entity, thereby necessitating the opening of a new application after which balances will be transferred and the current account closed.
- Moving to a new country may subject the client to different local regulations which, among other things, may impact the products you can trade. For example, U.S. regulations generally prohibit residents from trading non-U.S. securities options. Similarly, European regulations prohibit residents classified as Retail from trading certain packaged products such as ETFs where the issuer elects not to publish the required disclosure documents.
- Tax withholding rates on dividends are generally based upon the client's country of residency and the relocation to a new country may expose the client to withholding taxes that they were previously not subject to or withholding at a rate higher than that subject to previously.
