If you are a customer of IB UK are you from a strict juridical view customer of IB UK or IB LLC? Why I'm asking is that the European Union's Council directive 2003/48/EC entered in force as of 1st July 2005. This directive is about taxation of savings income in the form of interest payments. At least in Sweden they will include options and futures in the definition of interest. If your account is in the name of IB UK, they should inform the taxauthorities in your country of residence if this is a EU-Country. However if your account is considered as IB LLC, IB has no obligation to inform any taxauthority. Looking at various documents it seems to me that IB UK accounts are held by IB LLC. Someone Knows or Could IB give an answer?
what do you mean by "includes futures and options in the definition of interest"? interest on margin deposit ? capital gains can't be treated as interest. '
The Swedish Authorities have just widening what they think that they should inform other Eu-countries about.
If you have an account with IBUK then you are a customer of IBUK. If you have an account with IBLLC then you are a customer of IBLLC. Sorry I can't comment about taxes and judicial views, etc.
Steve, Someone on IB should know the answer. Must be an important matter also for IB. If the account is with IBUK, IB must for each client inside EU once a year send written information to the taxauthorities in the clients homecountry. IB must minimum state how much interest that the client has received. However if you look at the various forms you sign when opening an account with IBUK it seems very complicated to sort out if you are a client of IBUK or IBLLC.
