You need to be careful with this one. It is possible that they could have asked the wrong person but it could be that there could be other reasons they want your bank accounts. It is easy to turn it on it’s head by asking them why it is reasonable for you to be providing your bank account statements when they have not proved you are in receipt of rents. You could say that you are not adverse to complying with reasonable requests but first you must challenge them to put on the table their compelling evidence that you have been in receipt of income that you have not brought to their attention.
Of course this could be a catch 22 if there was compelling evidence of such as clearly you have not volunteered such information and HMRC. might also consider that any understatement was both deliberate and concealed.
Additionally you should carefully consider if there is anything else you should have reported or disclosed and didn’t
You won’t see much advice where HMRC have not got the correct taxpayer as they should get the correct person with where their information comes from. You would however be best to seek out advice on a fee basis as you are entering a potential argument area that might not come out to the best effect without a full review of your wealth and lifestyle
