USA I'm quite sure.With IBUK where is the account located that you are you paying the money into? Does the funding of IBUK account require you to send money into a UK account? If so you have done a remittance.
No, the money (USD account in USA) is sent by ACH account link to IB LLC (USA entity). Are you familiar with ACH? Automated clearing house - Wikipedia

"For your reference, Interactive Brokers (UK) Limited acts as an arranger for Interactive Brokers LLC. Interactive Brokers LLC holds clients funds and assets."
Thanks! Yeah it does seem quite clear. Also, my TX will be in USD and till stay USD.The example you quoted is clear as no offshore funds at any point were sent to UK. This is how it works in private banking in UK for non-doms. A non-dom can have a local banker who manages their assets held offshore and payment for that service takes place offshore and assets being managed offshore have no UK situs. The local banker in that example is compensated offshore thus no remittance has taken place by the client either in paying for assets or the service.
There's also the temporary exception, if the asset doesn't remain in UK less than something like 250 days I think it was, it also isn't a remittance. Cash just sitting there, transferred in, then transferred back out, even if it was into the UK, if it's less than this time then it's also not remitted AFAIK.
RDRM34210 - Residence, Domicile and Remittance Basis Manual - HMRC internal manual - GOV.UK
Remittance Basis: Exemptions: Exempt property - temporary importation rule
You should check the other guidance available on GOV.UK from HMRC as Brexit updates to those pages are being prioritised before manuals.
Property of any description that derives from foreign income or foreign chargeable gains that is brought to the UK is exempt property if it meets the temporary importation rule (ITA07/s809Z4(1)).
The temporary importation rule applies to such property which is brought to, or received or used in the UK so that Condition A of ITA07/s809L applies (refer to RDRM33120 Condition A - money and property) but it is in the UK for fewer than 275 ‘countable days’. If this rule is met, the bringing in of the property is not treated as a taxable remittance.
I have yet to execute on any of this - have been studying a lot. Now know far more about all this than I ever would have liked to
Thanks Martin! Your knowledge and patience is impressive. You sound like an interesting person!
