Thanks for your question - I am Sam and I am one of the UK tax experts here on Just Answer.
Cold you advise
1) From where does the foreign income arise is this OLD income or current/ongoing income, please expand - and is this usually declared to HMRC - or where do you pay tax on it - has any of this income been brought into the UK OR spent in the UK
2) Do you live and work in the UK - when did you arrive and how long do you plan to stay and what visits do you make out of the UK
3) What will the office be used for within this company you may consider purchasing it through what does your business trade in?
I can then advise further ( I may not respond to any reply to make until tomorrow morning - if that is acceptable)
Thanks for your response
As the office will be used in the business then its best to buy through the company so all expenses can be offset against profits.
If you use the income you have earned abroad (and none of it relates to earnings since you started working in the UK) and for those years you were treated as not resident by the UK tax authorities, then none of it will be considered liable to UK tax as earned whilst abroad and not resident (and I presume has nothing to do with the UK company) Your tax position lies in Bahrain
But then this tout sees you not having the company own the office and you cannot claim the costs that arise to run it, and instead would perhaps need to rent it to the limited company. (which then means you also have rental income as an individual to declare to the UK tax authorities)
If you take a loan out (whether from the UK or not) then just the interest element of any loan repayment can be claimed as an allowable expense (and of course then the running costs) as the company will own the office.
Do let me know if I can assist further, or need me to expand on the answers provided
