Introducing brokers

I intend to open an accoiunt with IKBR. Is there any advantage to do it through an Introducing Broker? If so would the account be LEGALLY an IBKR account or an Introducing Broker account? This may have implications such as tax, probate etc.

I find various definitions on the web of what an “Introducing Broker” would be. However, generally speaking they would act as a middleman between IBKR and you.

Given the rock-bottom fees of IBKR, I doubt it would lead to any significant savings (more likely the opposite) and you would have to deal with a greater level of complexity.
